Clinical results of arthroscopically-assisted lower trapezius transfer using fascia lata autograft for posterior superior irreparable rotator cuff tear

BackgroundDifferent interpositional grafts have been proposed to connect between the lower trapezius tendon (LTT) to the humerus during LTT transfer. While studies often mention the successful use of Achilles tendon allograft, there is currently no literature reporting the clinical outcomes of utilizing fascia lata autograft (FLA) in LTT transfer. Therefore, the current study aims to evaluate the clinical and radiologic results of LTT using FLA for posterior superior irreparable rotator cuff tears (PSIRCTs) without arthritis. Patient and methodsThe present study constitutes a retrospective case series involving 22 patients, with a mean follow-up of 35.9 ± 15.9 months. Pain levels were gauged using the Visual Analog Scale (VAS), while shoulder function was comprehensively assessed through the Constant and ASES (American Shoulder and Elbow Society) scores. The evaluation of shoulder activities in daily living employed the ADLER (Activities of Daily Living Requiring Active External Rotation) score. Active ROM (Range of Motion) of all directions were obtained, radiologic assessments included key parameters such as AHD (Acromion Humeral Distance) and the Hamada grade. Finally, the integrity of the transferred LTT was evaluated, and a subgroup analysis was undertaken based on Tm trophicity. ResultsBy the final follow-up period, VAS, Constant, ASES, and ALDER demonstrated significant improvement. Active ROM significantly improved in (FE) forward elevation to 155° ± 29°, abduction (Abd) to 140° ± 32°, external rotation (ER) at 90° Abd to 68° ± 19°, and ER at the side to 39° ± 17°. AHD and Hamada grade showed no significant arthritic progression. Tm hypertrophy group experienced superior improvements in ER compared to that of the non-hypertrophy group. Complications included re-tear (n = 2), infection (n = 1) and donor-site morbidity (n = 1). ConclusionThe study highlighted promising clinical outcomes of LTT transfer using FLA, with no significant complications. Along with Achilles tendon allograft, FLA can be a safe and viable alternative interpositional graft choice.

Joint-preserving treatment for global irreparable rotator cuff tears: combined anterior Latissimus dorsi and Teres major tendon transfer.

Treating global irreparable rotator cuff tears (GIRCTs) that involve both antero-and postero-superior cuff tendon tears could be a challenging problem. There has been limited joint-preserving treatment options in high-demand patients with minimal glenohumeral arthritis. The study aims to assess the clinical outcome of combined anterior latissimus dorsi and teres major tendon (aLDTM) transfer for patients with both GIRCTs and minimal glenohumeral arthritis. This retrospective study included patients who underwent combined aLDTM transfer for GIRCTs between 2018 May and 2020 October. Clinical outcomes include pain VAS, Constant, American Shoulder and Elbow Society (ASES), University of California Los Angeles (UCLA), activities of daily living requiring active internal rotation (ADLIR) score, active range of motion (aROM), strength, rates of pseudoparalysis or pseudoparesis reversal and return to work. Radiographic assessment included the acromiohumeral distance (AHD), Hamada grade, and transferred tendon integrity at final follow-up. 23 patients (mean age: 64.7 ± 5.9years [55-74]) were included and the mean follow-up period was 28.2 ± 4.3 [24‒36] months. Postoperatively, VAS, Constant, ASES, UCLA, and ADLIR scores significantly improved at final follow-up (P < .001). Postoperative aROM was significantly improved in forward elevation (FE) to 129° ± 29°, abduction (ABD) to 105° ± t3°, and internal rotation (IR) at back to 5.9 ± 2.5. Strength of both FE and IR were also significantly improved (P < .001). Patients with preoperative pseudoparalysis (2 of 4 patients) and pseudoparesis (6 of 6 patients) experienced a reversal. No significant change in AHD and hamada grade was confirmed at final follow-up. 3 patients experienced partial tear of the transferred tendon. In this study, we found significant improvement in clinical outcomes with no significant progression of arthritis by final follow-up. The aLDTM transfer could be an alternative choice of joint-preserving treatment option for young and active patients with GIRCTs and minimal glenohumeral arthritis. However, large and long-term studies should be conducted to establish its adequacy. Case series. IV.

Long-term Functional and Pain Outcomes Following Arthroscopic Partial-Thickness Rotator Cuff Tear Completion and Repair

Objective: There remains little consensus on the optimal treatment approach for partial-thickness rotator cuff tears and few studies have examined the long-term outcomes of different surgical repair techniques. The purpose of this study is to identify the long-term functional and pain outcomes of arthroscopic tear completion followed by repair. The authors hypothesize that this technique will allow patients to have long-term pain relief and return to a pre-injury level of function. Methods: Patients (n=16) who underwent arthroscopic tear completion and repair for a partial-thickness rotator cuff tear were included in this case series. Each patient returned for a one-time follow-up visit, with an average follow-up time of 7.09 years, at which time physical and neurological exams were performed, quality of life was assessed through subjective questionnaires, American Shoulder and Elbow Society (ASES) and the University of California at Los Angeles (UCLA) shoulder scores were obtained, and magnetic resonance imaging was performed. Results: The average ASES score was 85.3, with 81% of patients reporting that they were able to return to a pre-injury level of function. Half of the patients reported the highest possible UCLA shoulder score of 35. Physical examination showed that patients had excellent strength and range of motion. Magnetic resonance imaging demonstrated continuity of the repair in all but one patient. However, 25% of patients reported return of symptoms since surgery, including pain and limited mobility. Conclusion: At an average of 7.09 years follow-up, most patients were found to have full mobility, pre-injury level of activity, and maintenance of rotator cuff integrity in the surgically treated shoulder. However, one fourth of patients reported return of symptoms. The authors conclude that the tear completion and repair technique can lead to long-term functional improvement, but has less favorable results in terms of subjective pain level and quality of life.

SHOULDER AND ELBOW FUNCTION FOLLOWING ANTEGRADE HUMERAL NAILING AND PLATE FIXATION IN MIDDLE THIRD HUMERAL SHAFT FRACTURES

The choice of whether to perform antegrade intramedullary nailing (IMN) or plate fixation (PF) poses a conundrum for the surgeon who must strike the balance between anatomical restoration while reducing elbow and shoulder functional impairment. Most humeral middle third shaft fractures are amenable to conservative management given the considerable acceptable deformity and anatomical compensation by patients. This study is concerned with the patient reported outcomes regarding shoulder and elbow function for IMN and PF respectively.A prospective cohort study following up all the cases treated surgically for middle third humeral fractures from 2016 to 2022 at a single centre. Telephonically an analogue pain score, an American Shoulder and Elbow Society (ASES) score for shoulder function and the Oxford Elbow score (OES) for elbow function were obtained.One hundred and three patients met the inclusion criteria. Twenty four patients participated in the study, fifteen had IMN (62.5%) and nine had PF (37.5%.). The shoulder function outcomes showed no statistical difference with an average ASES score of sixty-six for the IMN group and sixty-nine for the PF group. Women and employed individuals expressed greater functional impairment. Hand dominance has no impact on the scores of elbow and shoulder function post operatively. The impairment of abduction score post antegrade nailing was higher in the antegrade nailing group than the plated group. The OES demonstrated greater variance in elbow function in the PF group with the IMN group expressing greater elbow disfunction.This study confirms that treatment of middle third humerus shaft fractures by plate fixation is marginally superior to antegrade intramedullary nailing in preserving elbow function and abduction ability.

Outcomes of Reverse Total Shoulder Arthroplasty for Proximal Humerus Fracture Versus Rotator Cuff Arthropathy.

Reverse total shoulder arthroplasty (RSA) is used to treat a variety of shoulder-related pathologies. This study compared medium-term clinical outcomes of less than 10-year follow-up in patients treated with RSA for proximal humerus fracture (PHF) versus rotator cuff arthropathy (RCA). This retrospective review was conducted at two tertiary care centers, in which self-reported clinical outcomes were assessed using four validated instruments, that is, American Shoulder and Elbow Society (ASES) score, Shoulder Pain and Disability Index (SPADI), visual analog scale (VAS), and shoulder subjective value (SSV). Statistical analyses were performed using linear or logistic regression with generalized estimating equations. Of the 189 patients included in this study, 70 were treated for fracture and 119 for RCA. At a mean postoperative follow-up of 6.4 years, the means were 79.7 for ASES score, 20.8 for SPADI-Total, 0.8 for VAS, and 77.1 for SSV. After adjusting models for covariates, there was no significant difference in average SSV (P = 0.7), VAS (P = 0.7) or SPADI-Pain (P = 0.2) between PHF and RCA cohorts; however, the RCA cohort reported significantly better outcomes in ASES scores (P = 0.002), SPADI-Disability (P < 0.0001), and SPADI-Total (P = 0.0001). Patients with RCA and PHF treated with RSA achieved similar medium-term outcomes in several domains, particularly postoperative pain levels; however, patients with PHF reported greater perceived disability. RSA is an effective pain-controlling procedure, but patients may have variable functional outcomes based on the indication for surgery.

Clinical effects of sodium hyaluronate combined with platelet-rich plasma injection on rotator cuff injury in arthroscopic repair

ObjectiveRotator cuff injury is one prevalent shoulder condition that often leads to pain and dysfunction. The study explored the clinical effects of sodium hyaluronate combined with platelet-rich plasma (PRP) injection on rotator cuff injury in arthroscopic repair. MethodsA total of 92 cases with rotator cuff injury were randomly divided into the control group (n = 46, treated with shoulder arthroscopy repair combined with subacromial space injection of sodium hyaluronate) and the experimental group (n = 46, treated with subacromial space injection of autologous PRP on the basis of the treatment in the control group). Visual analogue scale (VAS), Constant-Murley scale (CMS), University of California, Los Angeles (UCLA), American Shoulder and Elbow Society (ASES), and quality of life (QOL) scores, as well as complications were compared in the two groups before surgery and at 3 and 6 months after surgery. Shoulder range of motion (ROM) was measured before and after surgery. ResultsVAS scores of patients in the two groups at 3 and 6 months after surgery were lower than those before surgery, and the VAS scores of patients in the experimental group at 3 and 6 months after surgery were much lower than those in the control group (all P < 0.05). The scores of CMS, UCLA, ASES, and QOL, and shoulder ROM in both groups at 3 and 6 months after surgery were higher than those before surgery, and these shoulder joint function scores, QOL and shoulder ROM in the experimental group at 3 and 6 months after surgery were higher than those in the control group (all P < 0.05). No statistically significant difference presented in the incidence of complications between the two groups (P > 0.05). ConclusionArthroscopic rotator cuff repair and sodium hyaluronate combined with PRP injection can effectively reduce pain symptoms, improve shoulder joint function and shoulder ROM, and improve QOL in patients with rotator cuff injury.

Are Vascularized Fibula Autografts a Long-lasting Reconstruction After Intercalary Resection of the Humerus for Primary Bone Tumors?

A vascularized fibula graft (VFG) is the vascular autograft most frequently used to restore large segmental long bone defects, particularly in the upper limb. Because the use of a vascularized fibula involves an operation in an uninvolved extremity with potential morbidity, it is important to document that this type of reconstruction is successful in restoring function to the humerus. However, the long-term results of VFG after intercalary resection of the humeral diaphysis for bone tumors are still unknown. (1) What was the complication rate of reconstruction? (2) What was the functional result after surgical treatment, as assessed by the Musculoskeletal Tumor Society (MSTS) score, the American Shoulder and Elbow Society (ASES) score, and Constant score? (3) What was the survivorship of these grafts free from revision and graft removal at 5, 10, and 15 years? Between 1987 and 2021, 127 patients were treated at our institution with en bloc resection for a primary malignant or an aggressive benign bone tumor of the humerus; we excluded patients treated with extra-articular resection or amputation. Of those, 14% (18 of 127) were treated with intercalary resection of the humeral diaphysis for primary bone tumors and reconstruction with VFG, with or without a bulk allograft, and were analyzed in this retrospective study. Generally, our indications for reconstruction with VFG are intercalary resection of the humerus for primary malignant or aggressive benign bone tumors in patients with long life expectancy and high functional demands, in whom adequate bone stock of the proximal and distal epiphysis can be preserved. In 13 patients, VFG was used alone, whereas in five patients, a massive allograft was used. Our policy was to use VFG combined with a massive allograft in patients undergoing juxta-articular joint-sparing resections in which proximal osteotomy was performed close to the anatomic neck of the humerus to obtain more stable fixation and better tendinous reattachment of the rotator cuff and deltoid. All 18 patients who were treated with a VFG were available for follow-up at a minimum of 2 years (median follow-up 176 months, range 26 to 275 months), and although three have not been seen in the past 5 years and are not known to have died, they had 172, 163, and 236 months of follow-up, and were included. The median age at surgery was 25 years (range 2 to 63 years), the median humeral resection length was 15 cm (range 8 to 21 cm), and the median fibular length was 16 cm (range 12 to 23 cm). Complications and functional scores were ascertained by chart review that was performed by an individual not involved in patient care. Functional results were assessed with the MSTS score (range 0 to 30), the ASES score (range 0 to 100), and the Constant score (range 0% to 100%). Survivorship was estimated using a Kaplan-Meier survivorship estimator, which was suitable because there were few deaths in this series. Seven patients underwent a revision procedure (one radial nerve transient palsy because of screw impingement, four nonunions in three patients with one humeral head avascular necrosis, treatment for screw-related pain in one patient, and two VFG fractures), and one patient underwent VFG removal. Donor site complications were observed in four patients (one ankle valgus deformity and three claw toes-the first toe in two patients and the other toes in the third). At the final clinical control, at a median follow-up of 176 months (range 26 to 275 months), the median MSTS score was 30 of 30 (range 28 to 30), the median ASES score was 98.3 (range 93 to 100), and the median Constant score was 93.5% (range 79% to 100%). Revision-free survival was 71% (95% CI 53% to 96%) at 5 years and 57% (95% CI 37% to 88%) at 10 and 15 years; VFG removal-free survival was 94% (95% CI 83% to 100%) at 5, 10, and 15 years. VFG appears to be an effective reconstructive option after humeral intercalary resection for primary bone tumors. These are complex procedures and should be performed by an experienced team of surgeons who recognize that complications may occur frequently in the first years after the procedure. The frequency of mechanical complications observed in the first 5 years postoperatively may be lessened by using long spanning-plate fixation, and if successful, this reconstruction provides a long-term, durable reconstruction with excellent functional results. Level IV, therapeutic study.

All-Arthroscopic Glenoid Bone Augmentation Using Iliac Crest Autograft Procedure for Recurrent Anterior Shoulder Instability: Button Fixation Is a Feasible and Satisfactory Alternative to Screw Fixation

To investigate the efficacy of all-arthroscopic glenoid bone augmentation surgery using the iliac crest autograft procedure. Furthermore, we sought to compare the clinical and radiographic outcomes of using screw versus button fixation, in patients with recurrent anterior shoulder instability. Between 2015 and 2019, 134 shoulders with persistent instability were surgically treated with an arthroscopically placed autologous iliac crest bone graft transfer procedure. Preoperative and postoperative clinical follow-up data were evaluated using the range of motion, and the Walch-Duplay, American Shoulder and Elbow Society, and Rowe scores. Radiologic assessment on 3-dimensional computed tomography scans was performed preoperatively, immediately after surgery, as well as postoperatively, at 3months, 6 months, 1 year, and at the final follow-up stage. Graft positions, healing, and resorption were evaluated from postoperative images. This study included 102 patients who underwent arthroscopic iliac crest bone grafting procedure with 2 screws fixation (n= 37; group 1) and 2 button fixation (n= 65; group 2). The mean follow-up period was 37 months. There were no significant differences between groups in terms of clinical scores, shoulder motion range, graft healing, or graft positions on computed tomography scans (P>.05). In group 1, 1 patient showed mechanical irritation and persistent pain around the screw insertion site, being treated through the arthroscopic removal of the screws. The average postoperative bony resorption percentages were 20.3% and 11.2% at 6 months, and 32.4% and 19.3% at 12 months, in group 1 and group 2, respectively. A statistically significant difference was detected between the two groups (P<.05). In the arthroscopic iliac crest bone grafting procedure for the treatment of chronic osseous anterior shoulder instability, excellent functional results were obtained after both button fixation and screw fixation techniques. In addition, less graft resorption and no hardware-related complications were detected with suture button fixation technique. Level III, retrospective comparative therapeutic trial.

Adduction Manipulation of the Glenohumeral Joint versus Physiotherapy for Atraumatic Rotator Cuff Tears: A Randomized Controlled Trial.

Atraumatic rotator cuff tears (ARCTs) are frequently concomitant with adduction restriction of the glenohumeral joint (GHJ). Adduction manipulation (AM) removes the restriction and relieves pain. The present study aimed to investigate the clinical efficacy of AM versus physiotherapy (PT) in ARCTs. Eighty-eight patients with adduction restriction were allocated to the AM and PT groups (n = 44 per group). The glenohumeral adduction angle (GAA) was calculated using X-rays at the first and last follow-up appointments. We recorded pain severity (visual analog scale, VAS), flexion, abduction, external rotation (ER), internal rotation (IR), and American Shoulder and Elbow Society (ASES) and Constant scores at baseline and at 1-, 3-, 6-, and 12- month follow-ups. Forty-three patients (23 males, average age 71.3 years) in the AM group and 41 (16 males, average age 70.7 years) in the PT group were consequently analyzed. At the 1-month follow-up, VAS, shoulder motion except ER, ASES and Constant scores were much better in the AM group than in the PT group, whereas those in the PT group improved gradually up to 12 months. At the final follow-up, flexion, abduction, and Constant score were significantly better in the AM group than in the PT group. The GAA at the initial and final examinations was -21.6° and -3.2°, respectively, in the AM group, and -21.1° and -14.4°, respectively, in the PT group. The AM procedure, which had better clinical efficacy than PT, is recommended as the first conservative treatment option for ARCTs.

Assessment of the Arthroscopic Double-Row Restoration Technique's Reliability and Operational Results for Shoulder Cuff Reconstruction

Objective: This study aims at evaluating the effectiveness of shoulder cuff restoration by arthroscopic surgery in dual row repair mode and shows 30 months of practical results, an ASES-based scoring system was developed. Methods: This study was conduced at mayo hospital Lahore in orthopedics department and the duration of this study was from October 2021 to march 2023. 23 patients who had significant rotator cuff tears repaired arthroscopically in a double-row fashion are included in this cross-sectional research. The operating surgeon performed a clinical assessment on patients who had been admitted for surgery in the outpatient setting both before and after surgery, as well as during follow-up visits at six weeks, three months, six months, and one year. The last examination took place on average 30 months after surgery. Using a scoring system based on a modified ASES score, the function of the patient was evaluated both preoperatively and postoperatively, and the results were compared. Based on the Modified American Shoulder and Elbow Society (ASES) score, a patient-rated questionnaire was utilized to assess shoulder and elbow function. Three parts make up the questionnaire, the first of which included questions regarding pain and had six components with a total weight of 30 points. The existence of pain, its location, and if the patients had discomfort at night were all questions that were posed to the patients. A visual analog pain scale from 0 to 10 was used to assess the degree of the patient’s pain as well as their usage of drugs. The second phase, which included 10 components and a weighted average of 50 points, examined candidates' capacity to carry out everyday tasks. On a scale of 0 to 5, patients were asked to assess their level of competence to accomplish tasks while accounting for any challenges they may have encountered. The shoulder instability was evaluated in the last portion using a visual analog scale with a range of 0 to 10. Patients were divided into four groups based on the grading system: Excellent result (score &gt;75), Good outcome (score 50-75), Fair outcome (score 25-50), and Poor outcome (score &lt; 25) Results: At the time of the last follow-up, there was a substantial improvement in the mean operational result scores depending on the Patient Self-Assessed Questionnaire (p-value &lt; 0.01). By using magnetic resonance imaging to evaluate repair integrity 12 months after surgery, it was discovered that 16 patients had type-I repairs, 2 patients had type-II repairs, and only 1 patient had type-III repairs. For enormous tears, the study's retear rate was 5%. Comparing the type-III repaired shoulders to the other kinds of repaired shoulders, the type-III repaired shoulders showed substantially worse functional outcomes in terms of total scores and strength (p-value &lt; 0.01). Practical Implication: In the practical implication of this study we discovered that the arthroscopic double-row restoration approach is a successful treatment for repairing large rotator cuff injuries with a low chance of re-tear and a big increase in activity levels. Conclusions: In this research, we discovered that the arthroscopic double-row restoration approach is a successful treatment for repairing large rotator cuff injuries with a low chance of re-tear and a big increase in activity levels.

Shoulder Surgery Postoperative Immobilization: An International Survey of Shoulder Surgeons

There is currently no consensus on immobilization protocols following shoulder surgery. The aim of this study was to establish patterns and types of sling use for various surgical procedures in the United States (US) and Europe, and to identify factors associated with the variations. An online survey was sent to all members of the American Shoulder and Elbow Society (ASES) and European Society for Surgery of the Shoulder and Elbow (ESSSE). The survey gathered member data, including practice location and years in practice. It also obtained preferences for the type and duration of sling use after the following surgical procedures: arthroscopic Bankart repair, Latarjet, arthroscopic superior/posterosuperior rotator cuff repair (ARCR) of tears <3 cm and >3 cm, anatomic total shoulder arthroplasty (aTSA) and reverse TSA (rTSA), and isolated biceps tenodesis (BT). Relationships between physician location and sling type for each procedure were analyzed using Fisher's exact tests and post-hoc tests using Bonferroni-adjusted p-values. Relationships looking at years in practice and sling duration preferred were analyzed using Spearman's correlation tests. In total, 499 surgeons with a median of 15 years of experience (IQR = 9-25) responded, with 54.7% from the US and 45.3% from Europe. US respondents reported higher abduction pillow sling use than European respondents for the following: Bankart repair (62% vs. 15%, p < 0.0001), Latarjet (53% vs. 12%, p < 0.001), ARCR < 3 cm (80% vs. 42%, p < 0.001) and >3 cm (84% vs. 61%, p < 0.001), aTSA (50% vs. 21%, p < 0.001) and rTSA with subscapularis repair (61% vs. 22%, p < 0.001) and without subscapularis repair (57% vs. 17%, p < 0.001), and isolated BT (18% vs. 7%, p = 0.006). European respondents reported higher simple sling use than US respondents for the following: Bankart repair (74% vs. 31%, p < 0.001), Latarjet (78% vs. 44%, p < 0.001), ARCR < 3 cm (50% vs. 17%, p < 0.001) and >3 cm (34% vs. 13%, p < 0.001), and aTSA (69% vs. 41%, p < 0.001) and rTSA with subscapularis repair (70% vs. 35%, p < 0.001) and without subscapularis repair (73% vs. 39%, p < 0.001). Increasing years of experience demonstrated a negative correlation with the duration of sling use after Bankart repair (r = -0.20, p < 0.001), Latarjet (r = -0.25, p < 0.001), ARCR < 3 cm (r = -0.14, p = 0.014) and >3 cm (r = -0.20, p < 0.002), and aTSA (r = -0.37, p < 0.001), and rTSA with subscapularis repair (r = -0.10, p = 0.049) and without subscapularis repair (r = -0.19, p = 0.022. Thus, the more experienced surgeons tended to recommend shorter durations of post-operative sling use. US surgeons reported longer post-operative sling durations for Bankart repair (4.8 vs. 4.1 weeks, p < 0.001), Latarjet (4.6 vs. 3.6 weeks, p < 0.001), ARCR < 3 cm (5.2 vs. 4.5 weeks p < 0.001) and >3 cm (5.9 vs. 5.1 weeks, p < 0.001), aTSA (4.9 vs. 4.3 weeks, p < 0.001), rTSR without subscapularis repair (4.0 vs. 3.6 weeks, p = 0.031), and isolated BT (3.7 vs. 3.3 weeks, p = 0.012) than Europe respondents. No significant differences between regions within the US and Europe were demonstrated. There is considerable variation in the immobilization advocated by surgeons, with geographic location and years of clinical experience influencing patterns of sling use. Future work is required to establish the most clinically beneficial protocols for immobilization following shoulder surgery. Level IV.

Reverse Shoulder Arthroplasty for Patients with Massive Rotator Cuff Tears or Cuff Tear Arthropathies at a Minimum Follow-up of 7 Years.

To evaluate indications and factors that influence long-term clinical outcomes and revision rates for reverse shoulder arthroplasty (RSA) in shoulders with irreparable massive rotator cuff tears (mRCTs) or cuff tear arthropathies (CTAs). The authors retrospectively evaluated a consecutive series of shoulders with no fracture sequelae that underwent primary RSA between 2011 and 2013. Independent observers collected demographic data, surgical techniques, and implant types, as well as primary outcome measures such as American Shoulder and Elbow Society (ASES) score and Constant score (CS). Case series, level IV. From the initial series of 123 patients that underwent RSA, 29 patients died (24%) for reasons unrelated to the shoulder arthroplasty, 11 were lost to follow-up (9%), and 4 required revision surgery (3%). The final cohort of 79 patients comprised 55 women (70%), and 24 men (30%), aged 72.7 ± 7.0. At a final follow-up of 8.9 ± 0.6 years (range: 7.4-10.3) the absolute CS was 59.0 ± 16.2, the age-/sex-adjusted CS was 76.6 ± 41.2, and ASES was 77.1 ± 20.3. Univariable analysis revealed no associations for absolute CS, but revealed that age-/sex-adjusted CS was significantly lower for patients with high blood pressure (β = -15.8, p = .025). At a minimum follow-up of 7.4 years, the absolute CS was 59.0 ± 16.2, the age-/sex-adjusted CS was 87.4 ± 24.1 and ASES was 77.1 ± 20.3. When stratifying the outcomes of RSA by indication, there were no significant differences in patients with mRCTs versus CTA in terms of absolute CS, age-/sex-adjusted CS, and ASES. Univariable analysis revealed no association with absolute and age-/sex-adjusted CS for type of indication or surgical approach.

Clinical Outcome after Clavicular Hook Plate Fixation for Displaced Medial-End Clavicle Fractures.

Surgery of the medial end of the clavicle remains a challenge for orthopedic surgeons. Moreover, there is no standard surgical procedure for treating displaced fractures or dislocation of the medial clavicle. Thus, the present study aimed to evaluate the safety and efficacy of using a hook plate for treating medial-end clavicular fractures and present functional outcomes. We retrospectively investigated 18 patients who underwent surgery with a hook plate from July 2016 to December 2021. There were 14 men and 4 women with a mean age of 57.4 years. Fracture union was assessed at follow-up by computed tomography (CT). Other outcome parameters were complications, including implant failure, infection, nonunion, osteolysis of sternal manubrium, and migration of the hook portion. Range of motion (ROM), visual analog scale (VAS), Quick Disabilities of the Arm, Shoulder and Hand (Quick DASH), and American Shoulder and Elbow Society (ASES) scores were evaluated 6 months postoperatively and at the last follow-up. The mean operation time was 43.8 minutes (range, 35-50 minutes) and the mean follow-up was 22.8 months (range, 12-42 months). Bone union was confirmed in all cases. The mean union time was 6.2 months (range, 6-7 months). Implant removal was performed routinely according to the clinical course in 17 cases. The mean implant removal time was 10.0 months (range, 6-14 months). Clinical and functional outcomes measured at the last follow-up were significantly improved compared to those at 6 months postoperatively (p < 0.05). Regarding complications, there were 6 cases (33.3%) of osteolysis of the sternal manubrium. Although the anteroposterior length of the manubrium and hook depth showed significant differences between the non-osteolysis group and the osteolysis group (p = 0.024), ROM, VAS, Quick DASH, and ASES scores were not significantly different between the two groups (all p > 0.05). Clavicle hook plating can be a safe and effective method that can be easily applied with good outcomes if it is used with appropriate surgical planning and technique for medial-end clavicle fracture. CT scans are useful for preoperative planning and postoperative evaluation of bone union or complications.

Percutaneous Intramedullary Nailing of Complex Humeral Shaft Fractures: A Retrospective Case Series.

Humeral diaphyseal fractures have been traditionally stabilized with plates and screws. However, surgical morbidity can be quite extensive, particularly in more complex segmental and comminuted fracture patterns. An intramedullary nail (IMN) has the biomechanical advantage of being a load-sharing device and can be placed with a more minimally invasive technique. The purpose of this study was to evaluate the clinical and radiographic outcomes of complex humeral shaft fractures treated with an IMN utilizing a percutaneous surgical technique. A retrospective review was performed on a consecutive series of patients who underwent treatment of a complex humeral shaft fracture with an IMN placed with a percutaneous technique. Clinical outcome scores and radiographic analysis were performed at a minimum one-year follow-up. Of the 14 patients included, 12 had clinical and radiographic follow-ups at one year. The majority (64%) were obese and involved polytrauma (50%), and 79% were AO Foundation/Orthopaedic Trauma Association (AO/OTA) type C fractures. Union after the index procedure was 93%, with one nonunion requiring a secondary operation. The average operative time was 103 minutes. There were no other complications or additional procedures. The mean clinical outcome scores included American Shoulder and Elbow Society (ASES): 78.2, Constant Score: 72.1, Single Assessment Numerical Evaluation (SANE): 81.9, and Penn Shoulder Score: 82.7. This study demonstrates complex comminuted and segmental humeral shaft fractures in a higher-risk patient population can be effectively managed with IMN. Percutaneous placement of an IMN should be considered as a treatment option in complex humeral shaft fractures, particularly in patients with secondary comorbidities such as obesity and polytrauma.

Open Subpectoral Tenodesis for Isolated Traumatic Long Head of Biceps Tendon Rupture Provides Excellent Functional Outcomes in Active Male Patients.

For many years the long head of biceps tendon (LHBT) rupture has been described and is commonly identified by weakness, cramping, and the so-called "Popeye" sign. Traditionally, this was treated non-operatively, likely reflecting patient factors and the technical difficulty in reattaching a degenerative and shortened tendon. In contrast, traumatic distal biceps rupture is now commonly repaired despite historically being managed non-operatively. The advent of a convenient and reproducible surgical technique led to an increase in the rate of fixation, thereby improving the cramping and weakness associated with non-operative treatment. Given recent surgical advances within this field, many techniques are now present for LHBT pathology. We describe results from a cohort of patients suffering traumatic LHBT rupture who sought a surgical solution to improve their symptoms. Over four years, 18 male patients underwent surgical intervention for isolated traumatic LHBT rupture. The technique used involved an open subpectoral tenodesis with fixation of the LHBT into the bicipital groove. Postoperative immobilization using a sling was recommended for six weeks prior to a progressive rehabilitation program. Patients were assessed with pre- and postoperative visual analog scores (VAS) for pain and American Shoulder and Elbow Society (ASES) scores. The mean patient age at the time of surgery was 49 years (range: 26-65 years). The mean time to surgery was nine weeks (range: 2-24 weeks). All patients showed an improvement following surgery with a mean pre-op ASES score of 33 (range: 10-60) compared to a post-op score of 92.6 (range: 85-100). All patients were able to return to work and sport, with all but one returning to the same functional demand level of work. The mean pre-op pain VASwas 6.3 (out of 10) compared to 0.2 post-op. All patients had a requirement for analgesia pre-operatively and none had postoperatively. No surgical complications were observed. No correlation was observed between the time to surgery and the outcome. LHBT rupture is often treated non-operatively as few studies within the literature describe the surgical technique and outcomes from surgical intervention. When treated non-operatively, patients complain of pain, cramping, and cosmetic deformity known as the "Popeye" sign. Following a traumatic rupture of the LHBT, we have demonstrated excellent outcomes using a standard approach and common fixation technique that has the potential to improve the functional outcome for symptomatic patients. Open subpectoral biceps tenodesis is associated with excellent outcomes in symptomatic patients following isolated LHBT rupture.

Outcomes of arthroscopic-assisted middle trapezius tendon transfer for isolated irreparable supraspinatus tendon tears: minimum 2-year follow-up.

Middle trapezius tendon (MTT) transfer has been proposed as a feasible option for managing isolated irreparable supraspinatus tears (IISTTs). However, no clinical study has been attempted. This study aimed to evaluate clinical and radiologic outcomes of arthroscopic-assisted MTT transfer in patients with IISTTs. This retrospective study included patients who underwent arthroscopic-assisted MTT transfer using fascia lata autograft for IISTTs. Clinical outcomes, including pain visual analog scale (VAS), Constant, American Shoulder and Elbow Society (ASES), University of California Los Angeles (UCLA) shoulder scores and active range of motion (aROM), were assessed. Radiographic analyses included the acromiohumeral distance (AHD), Hamada grade, and transferred tendon integrity at the final follow-up. Twenty-two patients (mean age: 63.3 ± 6.8 [51‒74] years; mean follow-up period: 28.9 ± 4.9 [24‒44] months) met the study criteria. The mean VAS, Constant, ASES, and UCLA scores improved postoperatively at the final follow-up (p < 0.001). The mean aROMs for forward flexion and abduction were significantly increased postoperatively. No significant changes of AHD (p = 0.105) and Hamada grade (p = 0.815) were observed postoperatively. One patient had a re-tear of the transferred tendon at the footprint site at the final follow-up. In this minimum 2-year follow-up study of the novel aMTT transfer using fascia lata autograft, we found significant improvement in pain relief, clinical scores, and active forward flexion and abduction. Additionally, no significant progression of cuff tear arthropathy was observed at the final follow-up. Therefore, aMTT transfer could be a promising treatment option for patients with IISTTs. However, further multicenter and long-term trials are needed to verify its effectiveness. Retrospective case series, level IV.

Comparison of Extracorporeal Shock Wave Therapy and Ultrasound-Guided Shoulder Injection Therapy in Patients with Supraspinatus Tendinitis.

The present study compared the clinical effect of extracorporeal shock wave therapy (ESWT) with that of ultrasound (US)-guided shoulder steroid injection therapy in patients with supraspinatus tendinitis. We hypothesized that the two treatments would show comparable results. The inclusion criteria were age over 20 years and diagnosis of supraspinatus tendinitis using US. Ultimately, 26 patients were assigned using blocked randomization: 13 in the US-guided shoulder injection group and 13 in the ESWT group. Treatment outcomes were evaluated using the pain visual analog scale (pVAS), the American Shoulder and Elbow Society (ASES) score, and the Constant score at baseline and at 1 and 3 months after the procedure. At 1 month after the intervention, pVAS, ASES, and constant score were significantly higher in the US-guided shoulder injection group than in the ESWT group, but not at 3 months after the intervention. Both groups showed clinically significant treatment effects at 3 months after the intervention compared to baseline. No significance was shown using equivalence testing. US-guided shoulder injection therapy was not superior to ESWT therapy. Considering the complications and rebound phenomenon of steroid injections, interventions using ESWT may be a good alternative to treat patients with supraspinatus tendinitis.

Comparison of Treatment Options of Three- and Four-Part Humerus Proximal Fractures in Patients Over 50 Years of Age.

IntroductionOur aim was to evaluate different treatment methods including conservative treatment (CT), locking-plate osteosynthesis (OS) and hemiarthroplasty (HA) in three- and four-part humeral fractures in patients older than 50 years.MethodsForty-seven patients that have at least one year of follow-up were divided into three groups: 18 patients treated with OS, 14 patients treated conservatively and 15 patients treated with HA. For further evaluation, constant shoulder score, disabilities of the arm, shoulder and hand score (DASH), American Shoulder and Elbow Society (ASES) score had been used. Shoulder range of motion was also assessed.ResultsOS and CT groups had better scores than HA group. In OS group, average Constant score was 71.6 ± 16.2, DASH score was 12.1 (5.2-24.2) and ASES score was 77.5 (50.8-96.6). In CT group, average Constant score was 69.6 ± 19.2, DASH score was 16.4 (12.5-36.7) and ASES score was 76.6 (45.4-87.9). DASH scores (p = 0.032), Constant scores (p = 0.001), forward elevation (p < 0.001), abduction (p < 0.001), internal (p = 0.022) and external rotation (p = 0.048) were significantly improved in OS and CT groups than HA group.ConclusionsHA should not be considered a priority in surgical planning in Neer three-part and four-part proximal humerus fractures. CT is superior for patients with additional morbidity and advanced age. But in patients who are younger and can tolerate the surgical procedure, the priority should be OS.

Subacromial Balloon Spacer versus Partial Repair for Massive Rotator Cuff Tears: A Prospective, Randomized, Multi-center Trial

Objectives:Despite various treatment options, the successful management of irreparable, massive rotator cuff tears (MRCTs) remains challenging. Implantation of a biodegradable subacromial balloon spacer (InSpaceTM system; OrthoSpace, Caesarea, Isreal) has gained considerable interest for the treatment of MCRTs due to its ability to effectively recenter the humeral head within the glenoid. Despite promising results, investigations examining outcomes following balloon spacer implantation are limited to small case series and short-term prospective trials without comparison to other surgical modalities. The purpose of the present investigation was to prospectively evaluate the safety and efficacy of the arthroscopically deployed, subacromial spacer balloon compared to partial rotator cuff repair in patients with MRCTs at 24 month follow up.Methods:A non-inferiority, prospective, single-blinded, multicenter, randomized, controlled, pivotal study was conducted to compare the outcomes of arthroscopic subacromial balloon spacer implantation to partial repair in the treatment of MRCTs. Patients ≥ 40 years of age with symptomatic full thickness MRCTs (tears ≥ 5 cm or ≥ 2 tendons) that had failed non-operative management were included. Clinical outcome data, derived from subjective questionnaires and physical examination, were collected at baseline and follow-up intervals at Day 10, Week 6, Month 3, 6, 12 and 24. Postoperative magnetic resonance imaging (MRI) scans were obtained at 6 weeks and 12 months. The primary composite effectiveness endpoint was defined as achievement of the minimal clinically important difference (MCID) for the Western Ontario Rotator Cuff (WORC) score (275 points) and American Shoulder and Elbow Society (ASES) score (6.4 points) by week 6 and maintenance at month 12 without subsequent secondary surgical intervention (SSSI) or serious adverse device effects (SADEs). Secondary effectiveness endpoints included changes in individual and composite clinical outcome scores relative to baseline in addition to MRI findings. Intention-to-treat (ITT), per-protocol (PP), and safety analyses were performed separately.Results:A total of 20 sites were enrolled in the investigation. One hundred, eighty-four patients were randomized into the clinical study (n= 93 balloon spacer; n= 91 partial repair) and included in the safety population, of which 183 patients were included in the ITT analysis (n=93 balloon spacer; n= 90 partial repair) and 176 in the PP analysis (n= 88 balloon spacer; n= 88 partial repair). No significant difference in demographic characteristics based on mean age, sex, race or body mass index were appreciated between groups. Mean procedure duration was 44.6 ± 16.9 minutes for the balloon spacer group and 71.2 ± 30.1 minutes for the partial repair group. Significant improvement over time relative to baseline was observed in all WORC (Fig. 1) and ASES (Fig. 2) scores in both groups. The magnitude of improvement for subjects in the balloon spacer group was the same or better than for subjects in the partial repair group at 12 and 24 month follow up. At 12 months, 51% (n=45 of 88) of patients in the balloon spacer group and 35 patients 40% (n= 35 of 88) in the partial repair group had reached and maintained the primary composite endpoint, meeting the noninferiority criteria (non-inferiority margin 10%; p = 0.0049) and corresponding to an 11.4% mean advantage for the spacer implant group. Non-inferiority was similarly confirmed in the ITT population (p=0.0089). SSSI occurred in 6 subjects (n=3 balloon spacer; n=3 partial repair), with two subjects in each group requiring reverse shoulder arthroplasty and one subject in each group undergoing shoulder arthroscopy.Conclusions:Use of the balloon spacer was found to produce non-inferior outcomes when compared to partial rotator cuff repair for patients with MRCTs at 24 month follow up. Outcomes following balloon spacer device placement met non-inferiority criteria when compared to the partial repair group based on primary composite endpoints.
