Establishing Clinical Significance for Patients Undergoing Arthroscopic Repair of Type II SLAP Lesions.

Type II superior labrum anterior to posterior (SLAP) lesions may be treated with either arthroscopic repair or biceps tenodesis. There are no previous reports of measures of clinically significant improvement after arthroscopic repair of SLAP lesions. To establish the minimal clinically important difference (MCID), Patient Acceptable Symptom State (PASS), and substantial clinical benefit (SCB) for patients undergoing arthroscopic repair for type II SLAP lesions. Case series; Level of evidence, 4. A total of 69 arthroscopic repair procedures for isolated type II SLAP lesions were performed in a military population. The mean age was 28.1 ± 4.7 years, 97.1% were male, and the mean follow-up was 99.5 ± 19.7 months. The MCID, PASS, and SCB were calculated for each patient-reported outcome measure, consisting of the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) for pain, using anchor- and distribution-based models. Factors associated with achieving a clinically relevant improvement were also determined. The MCID, PASS, and SCB for each measure were as follows: 7.7, 70, and 34 for the ASES score, respectively; 10.4, 80, and 45 for the SANE, respectively; and 1.0, 4, and 6 for the VAS pain, respectively. At least 85% of patients achieved the MCID for each measure; however, PASS rates were lower, with 50.7% for the SANE and 69.6% for both the ASES score and VAS pain. The ASES score had the highest percentage of patients achieving the SCB at 44.9%, followed by the SANE (26.1%) and VAS pain (10.1%). Greater forward flexion at final follow-up was associated with achieving the MCID and PASS for both the ASES score and SANE. Internal rotation stiffness at final follow-up was negatively associated with achieving the PASS for the VAS pain. Combat arms military occupational specialty was associated with a lesser likelihood of achieving the SCB for the ASES score. Clinical metrics of improvement were defined for the ASES score, SANE, and VAS pain using the MCID, PASS, and SCB for patients undergoing arthroscopic repair of type II SLAP lesions. Better final range of motion was positively associated with achieving improvement, while high-intensity military duty was negatively associated.

Increasing the Knee Arc of Motion in Patients With Arthrogryposis: Minimum 2-year Follow-up.

Surgery for knee flexion contractures in patients with arthrogryposis multiplex congenital (AMC) have achieved extension to redirect the arc of motion and improve ambulation but has not demonstrated maintained increases in total range of motion (ROM). This study aimed to review the clinical outcomes of combined posterior knee release, proximal femoral shortening, and nerve decompression in patients with arthrogryposis. A retrospective chart and radiographic review were performed on patients with AMC who underwent treatment for knee flexion deformities ≥30 degrees. ROM, ambulation status, and orthotic use were reviewed and analyzed. Complications were recorded. Twenty-nine patients with 51 knees and a mean age of 5.7 years were included. The mean follow-up was 36.9 months. The mean ROM increased from 49 to 80 degrees between pre-op and latest follow-up (P<0.0001). The mean final follow-up flexion deformity was 10 degrees (P<0.0001). Preoperative ROM was moderately correlated with final ROM (rs=0.51). The percentage of ambulatory patients improved from 39% to 93%. Five limbs experienced a fracture either intraoperatively or postoperatively, and 5 limbs required a return trip to the operating room. Improved ambulation and knee ROM can be maintained in patients with AMC at a minimum 2-year follow-up. Prospective investigation and longer follow-up are required to validate these findings. Level IV-therapeutic.

A Short-term clinical and radiologic outcomes of reverse total shoulder arthroplasty with navigation system in Asian population: A retrospective comparative study

BackgroundIn reverse total arthroplasty (rTSA), glenoid component positioning is a critical factor for outcomes especially in Asian population with smaller glenoid. The purpose of this study was to compare the clinical and radiologic outcomes of rTSA with and without the navigation system with a minimum follow-up of two years in Asian population. MethodsThis was a retrospective comparative study of 33 rTSA with the navigation system (NAV group) and 40 conventional rTSA (CON group). Radiologic measurements regarding the position of the glenoid component, glenoid vault perforation by the central cage, and scapular notching, as well as clinical outcomes including range of motion (ROM), functional scores and complications were compared. Number, length, and angulation of screws were assessed. ResultsThe mean age was 73.9 ± 5.9 years with a mean follow-up of 30.1 ± 6.4 months. The NAV group more frequently utilized augmented baseplate (P < 0.001), showed less superior inclination (P = 0.030) and had lower incidence of glenoid vault perforation (P = 0.040). The length of superior (P = 0.001) and inferior screws (P = 0.045) was longer in the NAV group. In the NAV group compared to the CON group, more inferior orientation of superior screws (P < .001), more anterior orientation for inferior screws (P = 0.031), and anterior screws (P = 0.003) were observed. The NAV group showed significantly less penetration into the suprascapular fossa by a superior screw (P = 0.007). Final ROM, functional scores, and complications showed no significant differences between two groups. ConclusionIn short-term follow-up, the use of a navigation system in rTSA showed no significant difference in clinical outcomes and complications compared to conventional implantation. However, it enabled a lower superior inclination and a reduced glenoid vault perforation by the central cage, simultaneously allowing for the insertion of longer peripheral screws in a safer direction compared to conventional implantation.

Operative treatment of clavicle fractures results in more opioids prescribed as compared to non-operative management.

The operative treatment of mid-shaft clavicle fractures shows benefit in union rates, return to work, and lower pain scores relative to non-operative treatment. We sought to determine if the surgical treatment of isolated mid-shaft clavicle fractures would result in fewer opioids prescribed as compared to those managed non-operatively. All mid-shaft clavicle fractures treated at a Level 1 trauma center were identified from 2012 to 2016. Demographics, fracture characteristics, surgical complications/outcomes, non-operative outcomes, and all narcotics prescribed for 6 months post-injury were collected. Narcotic prescriptions, in morphine equivalents (ME), were obtained through the state prescription drug monitoring program (PDMP). One hundred and ten operative and 48 non-operative patients were included. Age, gender, previous alcohol, tobacco or drug use, and final range of motion were similar between groups. Pre-treatment fracture shortening (1.8cm vs. 0.7cm, p < 0.001) and displacement (150% vs. 70%, p < 0.001) were greater in the operative group. Total ME's (604 vs. 187, p < 0.001) and post-operative ME's (420 vs. 187, p < 0.001) were greater for the operative group. In either group, no other variable influenced ME's prescribed. Clavicles treated operatively receive substantially more opiates than those treated non-operatively, despite data suggesting that operative treatment makes clavicle fractures less painful. The total amount of narcotic analgesics obtained by operatively treated patients was over three times that obtained by non-operatively managed patients, which equates to 55 5mg oxycodone pills or 85 5mg hydrocodone pills per patient. While there may certainly be advantages to the operative treatment of clavicle fractures, they must be weighed against the risks of a significant increase in opiate prescribing and potential consumption.

Cervical Collar Use Following Cervical Spine Surgery: A Systematic Review.

The utility and risks associated with the use of cervical collars in the postoperative period after cervical spine surgery have been of debate. The purpose of this study was to systematically review the currently available evidence on the use of cervical collars after cervical spine surgery to assess their impact on outcomes. A literature search of the PubMed database was performed using keywords "cervical collar," "anterior cervical discectomy and fusion (ACDF)," "posterior cervical decompression and fusion," "laminoplasty," "post-operative orthotic bracing," "cervical decompression," and "cervical orthosis" in all possible combinations. All English studies with the level of evidence of I to IV that were published from May 1, 1986, to December 3, 2023, were considered for inclusion. A total of 25 articles meeting the inclusion criteria were identified and reviewed. Regarding anterior and posterior fusion procedures, cervical collar use demonstrated improved short-term patient-reported outcomes and pain control. While surgeon motivation for collar use was to increase fusion rates, this is not well drawn out in the literature with the majority of studies demonstrated no significant difference in fusion rates between patients who wore a cervical collar and those who did not. Regarding motion-preserving procedures such as cervical laminoplasty, patients with prolonged postoperative cervical collar use demonstrated increased rates of axial neck pain and decreased final range of motion (ROM). Surgeon motivation for postoperative cervical collar immobilization after completion of fusion procedures is to increase fusion rates and improve postoperative pain and disability despite this not being fully drawn out in the literature. After completion of motion-sparing procedures, the benefits of collar immobilization diminish with their prolonged use which could lead to increased rates of axial neck pain and decreased ROM. Cervical collar immobilization in the postoperative period should be considered its own intervention, with its own associated risk-benefit profile. Therapeutic Level III.

Prospective randomized comparison of functional bracing versus rigid immobilization with early weightbearing after modified percutaneous achilles tendon repair under local anesthesia

ObjectiveThe optimal treatment and rehabilitation strategy for acute Achilles tendon rupture (ATR) remain a debate. This study aimed to compare the results of the two postoperative regimens after treatment for ATR with modified closed percutaneous repair under local anesthesia. MethodsIn a 4-year study, 72 consecutive patients with acute complete ATR were randomized after percutaneous repair into a functional group (FG), using a modified brace (28 males, three females; mean age 41.9 [29–71] years) and an immobilization group (IG), wearing a rigid plaster (28 males, two females; mean age 42.2 [29–57] years), for a period of 6 weeks. Except for immobilization, they followed the same weight-bearing and rehabilitation protocols. The follow-up period was 3 years. The complication rate, active and passive ankle range of motion, standing heel-rise test, clinical outcome using the American Foot and Ankle Society (AOFAS) hindfoot-ankle score, return to the previous activity level, and subjective assessment were assessed. ResultsThere was one rerupture in the IG and two transient sural nerve disturbances in the FG and one in the IG, and one suture extrusion in the IG, with no other complications. The average AOFAS scores were 96.9 ± 4.3 and 96.0 ± 4.9 in the FG and IG, respectively. Patients in the FG reached a final range of motion and muscular strength sooner without limping and were more satisfied with the treatment. No significant differences could be detected between groups according to the results in any of the assessed parameters. ConclusionEarly dynamic functional bracing in patients with ATR treated with modified closed percutaneous repair under local anesthesia resulted in earlier functional recovery with similar final results in terms of complications and functional outcomes, such as rigid postoperative immobilization with standardized rehabilitation and weight-bearing protocol.

Does the distal radioulnar joint orientation influence the outcome of ulnar shortening osteotomy: a retrospective study.

The aim of this retrospective study was to evaluate the long-term outcome of ulnar shortening osteotomy. A total of 66 patients treated with an ulnar shortening osteotomy for a primary or post-traumatic ulnar impaction syndrome were included, with a median follow-up time of 75 months.There was a positive correlation between the sigmoid notch angle and the final QuickDASH score, but no correlation with final range of motion, grip strength or pain level. Radiological signs of osteoarthritis of the distal radioulnar joint were seen in 20% of patients, yet there was no correlation between the development of distal radioulnar joint osteoarthritis and the sigmoid notch angle. No symptomatic distal radioulnar joint osteoarthritis was observed.Ulnar shortening osteotomy is a good option to treat patients with ulnar impaction syndrome regardless of the distal radioulnar joint angle.Level of evidence: IV.

Outcomes of isolated medial tibial plateau fractures by fracture morphology

PurposeTo identify a cohort of isolated medial tibial plateau fractures treated with surgical fixation and to categorize them by Moore and Wahlquist classifications in order to determine the rate of complications with each fracture morphology and the predictive value of each classification system. We hypothesized there would be high rates of neurovascular injury, compartment syndrome, and complications overall with a higher incidence of neurovascular injury in Moore type III rim avulsion fractures and Wahlquist type C fractures that enter the plateau lateral to the tibial spines. MethodsPatients who presented to six Level I trauma centers between 2010 and 2021 who underwent surgical fixation for isolated medial tibial plateau fractures were retrospectively reviewed. Data including demographics, radiographs, complications, and functional outcomes were collected. ResultsOne hundred and fifty isolated medial tibial plateau fractures were included. All patients were classified by the Wahlquist classification of medial tibial plateau fractures, and 139 patients were classifiable by the Moore classification of tibial plateau fracture-dislocations. Nine percent of fractures presented with neurovascular injury: 5 % with isolated vascular injury and 6 % with isolated nerve injury. There were no significant differences in neurovascular injury by fracture type (Wahlquist p = 0.16, Moore p = 0.33). Compartment syndrome developed in two patients (1.3 %). The average final range of motion was 0.8–122° with no difference by Wahlquist or Moore classifications (p = 0.11, p = 0.52). The overall complication rate was 32 % without differences by fracture morphology. The overall rate of return to the operating room (OR) was 25 %. ConclusionsIsolated medial tibial plateau fractures often represent fracture-dislocations of the knee and should receive a meticulous neurovascular exam on presentation with a high suspicion for neurovascular injury. No specific fracture pattern was found to be predictive of neurovascular injuries, complications, or final knee range of motion. Patients should be counseled pre-operatively regarding high rates of return to the OR after the index surgery.

Outpatient versus inpatient shoulder arthroplasty outcomes using an updated patient-selection algorithm: minimum two-year follow-up

BackgroundPrevious studies have demonstrated the safety and cost-effectiveness of outpatient total shoulder arthroplasty (TSA), with the majority of studies focusing on 90-day outcomes and complications. Patient selection algorithms have helped appropriately choose patients for an outpatient TSA setting. This study aimed to determine the outcomes of TSA between outpatient and inpatient cohorts with at least a 2-year follow-up. MethodsA retrospective review identified patients older than 18 years who underwent a TSA with a minimum of 2-year follow-up in either an inpatient or outpatient setting. Using a previously published outpatient TSA patient-selection algorithm, patients were allocated into three groups: outpatient, inpatient due to insurance requirements, and inpatient due to not meeting algorithm criteria. Outcomes evaluated included visual analog scale (VAS) pain, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, range of motion (ROM), strength, complications, re-admissions, and re-operations. Analysis was performed between the outpatient and inpatient groups to demonstrate the safety and efficacy of outpatient TSA with midterm follow-up. ResultsA total of 779 TSA were included in this study, allocated into the outpatient (N = 108), inpatient due to insurance (N = 349), and inpatient due to algorithm (N = 322). The average age between these groups was significantly different (59.4 ± 7.4, 66.5 ± 7.5, and 72.5 ± 8.7, respectively; P < 0.0001). All patient groups demonstrated significant improvements in preoperative to final patient-outcomes scores, ROM, and strength. Analysis between cohorts showed similar final follow-up outcome scores, ROM, and strength, with few significant differences that are likely not clinically different, regardless of surgical location, insurance status, or meeting patient-selection algorithm. Complications, reoperations, and readmissions between all three groups were not significantly different. ConclusionThis study reaffirms prior short-term follow-up literature. Transitioning appropriate patients to outpatient TSA results in similar outcomes and complications compared to inpatient cohorts with mid-term follow-up.

Reverse shoulder arthroplasty for patients with cuff tear arthropathy: do clinical outcomes differ by inlay vs. onlay design?

The influence of position of the humeral tray (inlay or onlay) on clinical outcomes in reverse shoulder arthroplasty (RSA) is a topic of debate. The purpose of this study was to compare clinical and radiographic outcomes of patients with cuff tear arthropathy treated with RSA systems with inlay or onlay humeral tray design, similar neck-shaft angles, and lateralized glenospheres. This was a retrospective study of prospectively obtained data from 1 tertiary care center. We identified all patients who underwent primary RSA between 2009 and 2017 (N=511). We included 102 patients with diagnosed cuff tear arthropathy treated with RSA prostheses with a lateralized glenosphere and 135° neck-shaft angle (with either an inlay or onlay humeral tray design) who had a minimum of 2 years of follow-up (mean, 44months; range, 24-125months). Sixty-three patients (62%) had an inlay humeral tray (inlay group) and 39 (38%) had an onlay tray (onlay group). All patients underwent preoperative and postoperative evaluations, including measures of patient-reported outcomes (PROs), shoulder range of motion (ROM) testing, and radiographic imaging. Clinical relevance of changes in PROs and ROM was evaluated using published values for minimal clinically important differences. The 2 groups did not differ by demographic characteristics except for a higher proportion of women in the inlay group (75%) than in the onlay group (56%) (P=.04). Preoperative PROs and ROM were not significantly different between groups. At final follow-up, PROs and ROM were not different between groups in terms of statistical significance or clinical relevance. We found no significant differences in the rate of baseplate loosening (inlay, 3.2% vs. onlay, 5.1%, P=.63), revision surgery (inlay, 0% vs. onlay 5.1%, P=.07), acromial stress fracture (inlay, 3.2% vs. onlay, 5.1%, P=.63), prosthesis dislocation (inlay, 0% vs. onlay, 2.6%, P=.20), or scapular notching (inlay, 21% vs. onlay, 7.7%, P=.08). At 2-year minimum follow-up, the position of the humeral tray in RSA prostheses (either inlay or onlay) for cuff tear arthropathy was not associated with PROs, shoulder ROM, or rates of complications, including baseplate loosening, acromial stress fracture, and scapular notching.

Is there a role for acromioplasty and tuberoplasty in reverse shoulder arthroplasty to improve impingement-free range of motion?

Hypothesis and BackgroundLateralizing the center of rotation in reverse shoulder arthroplasty (RSA) decreases the risk of scapular notching due to inferior impingement but may limit range of motion (ROM) in abduction and forward flexion related to superior acromial impingement. Our primary hypothesis was that, using a 3-dimensional (3D) computer model, a virtual acromioplasty (with or without tuberoplasty) could improve abduction and forward flexion following RSA for cuff tear arthritis (CTA) or massive cuff tear. Our secondary hypothesis was that, based on the virtual planning, a surgical acromioplasty could be performed safely during RSA, without increasing the risk of postoperative acromial fracture. MethodsEighty seven patients with CTA scheduled for RSA were analyzed with a 3D software and impingement-free ROM was measured. After virtual prosthesis implantation, early acromio-humeral impingement (abduction ≤ 80° or forward flexion ≤ 120°) was observed in 25% of the cases (22/87). A virtual acromioplasty (with or without tuberoplasty) was then performed and glenohumeral ROM was measured again. Based on this 3D planning, a surgical acromioplasty (with or without tuberoplasty) was performed to improve ROM in the vertical plane in these 22 patients with early acromial impingement. Patients were followed with minimum 24 months of follow-up to assess final shoulder ROM and complications. ResultsAfter virtual acromioplasty alone (n = 11) or acromioplasty with tuberoplasty (n = 11), glenohumeral abduction significantly increased from 75° ± 6.9 before to 89.5° ± 23.4, and forward flexion from 119.3° ± 12 to 135.2° ± 10 (P < .001). After surgical acromioplasty/tuberoplasty, the final mean global forward flexion was 148° ± 5 and mean global abduction 150° ± 8 in these patients. At last follow-up, no acromial fracture was observed. ConclusionIn a 3D model, early acromial impingement may limit abduction (≤80°) or forward flexion (≤120°) after virtual RSA implantation for CTA or massive cuff tear. Virtual acromioplasty (with or without tuberoplasty) shows improved ROM in abduction and flexion. In patients with early impingement, a surgical acromioplasty can be performed safely during RSA, through a deltopectoral approach, without increasing the risk of postoperative acromial fracture.

Anatomic shoulder arthroplasty in patients 40 years or younger

BackgroundGlenohumeral arthritis in adults less than 40 years old represents a challenging clinical scenario to manage. While patients older than 55 have had reproducible success with current shoulder arthroplasty techniques, young patients have historically had less successful outcomes, possibly due to higher physical demands and more complex pathologies. Despite these concerns, anatomic total shoulder arthroplasty (TSA) remains the treatment of choice for young, active patients with severe glenohumeral arthritis and intact rotator cuff. We hypothesize that TSA provides significant relief in pain and functional outcomes in patients less than 40 years old. MethodsWe performed a single-institution retrospective analysis of consecutive patients aged 40 years and younger who underwent TSA between 2007 and 2022. Demographic data included age, sex, body mass index, Charlson comorbidity index, and preoperative diagnosis. Outcome measures included the Single-Assessment Numerical Evaluation (SANE) score, final range of motion, complications, and revision rate. Statistically significant differences between variables were evaluated using a 2-sample t-test at an α level of P < .05. ResultsTwenty-six TSAs were performed in 23 patients with an average final follow-up of 2 years after the procedure. The average age was 33.4 ± 5.3 years with a range of 19-39 years. The most common preoperative diagnosis was osteoarthritis (46%), followed by rheumatoid arthritis (27%) and osteonecrosis/avascular necrosis (19%). The most common glenoid morphology was type B (15) of which 14 were B2 glenoid, followed by type A (11). The SANE score, mean active forward elevation, abduction, external rotation, and internal rotation all improved significantly (P < .05) by the final follow-up. On average, patients in all groups were able to achieve minimal clinically important difference in SANE score after 1 year. There was 1 complication reported of an early postoperative infection treated with irrigation and débridement, and no revision surgeries were performed during the follow-up period. Discussion/ConclusionTSA significantly improved functional outcome measures in patients less than 40 years old with a low rate of complications and revisions in short-term outcomes. As the frequency of TSA continues to increase in adults less than 40 years old, additional studies recording long-term functional outcomes and implant survivorship in this population can be explored.

Teardrop Alignment Changes After Volar Locking Plate Fixation of Distal Radius Fractures With Volar Ulnar Fragments.

We assessed factors associated with change in radiographic teardrop angle following volar locking plate (VLP) fixation of volarly displaced intra-articular distal radius fractures with volar ulnar fragments (VUF) within the ICUC database. The primary outcome was change in radiographic alignment on follow-up imaging, defined as a change in teardrop angle from intra-operative fluoroscopy greater than 5°. Patients with distal radius fractures treated with a VLP within the ICUC database, an international collaborative and publicly available dataset, were identified. The primary outcome was volar rim loss of reduction on follow-up imaging, defined as a change in radiographic alignment from intra-operative fluoroscopy, teardrop angle less than 50°, or loss of normal radiocarpal alignment. Secondary outcomes were final range of motion (ROM) of the affected extremity. Radiographic Soong classification was used to grade plate position. Descriptive statistics were used to assess variables' distributions. A Random Forest supervised machine learning algorithm was used to classify variable importance for predicting the primary outcome. Traditional descriptive statistics were used to compare patient, fracture, and treatment characteristics with volar rim loss of reduction. Volar rim loss of reduction and final ROM in degrees and as compared with contralateral unaffected limb were also assessed. Fifty patients with volarly displaced, intra-articular distal radius fractures treated with a VLP were identified. Six patients were observed to have a volar rim loss of reduction, but none required reoperation. Volar ulnar fragment size, Soong grade 0, and postfixation axial plate position in relation to the sigmoid notch were significantly associated (P < .05) with volar rim loss of reduction. All cases of volar rim loss of reduction occurred when VUF was 10.8 mm or less. The size of the VUF was the most important variable for predicting volar rim loss of reduction followed by postfixation plate position in an axial position to the sigmoid notch and the number of volar fragments in the Random Forest machine learning algorithm. There were no significant differences in ROM between patients with volar ulnar escape and those without.

The Influence of Insurance Status on Extensor Tendon Repair Outcomes

Background: Little is known regarding how patient insurance status influences outcomes after extensor tendon-injury repair. We aim to establish a relationship between the outcomes of primarily repaired extensor tendon injuries and patient insurance status. We hypothesize that commercially insured patients will achieve superior outcomes due to more facile access to postoperative hand therapy and fewer barriers to appropriate postoperative care. Methods: A retrospective chart review was conducted of patients who underwent primary extensor tendon repair in any zone, excluding the thumb, at a single large safety-net hospital. Inclusion criteria included a minimum of eight weeks of follow-up, complete data available for review, and an extensor tendon injury requiring primary surgical repair. Four cohorts were examined: patients with commercial insurance, patients with Medicare/Medicaid, patients with county hospital-sponsored insurance, and uninsured patients. Statistical analysis was performed using Chi-Square and ANOVA analyses, with significance defined as p ≤ 0.05. Results: Of the 62 patients (100 digits) included, 20 had commercial insurance, 12 had Medicare/Medicaid, 13 had hospital-sponsored insurance, and 17 were uninsured. Except for mean age, there were no significant differences between groups in terms of demographic data, medical comorbidities, or digit characteristics. There were also no significant differences in mean follow-up, time to return to full activity, or surgical complications among groups. Procedure duration differed significantly between groups, with procedures lasting longer in uninsured patients. Postoperative final flexion total arc of motion (TAM) and extension measurements were similar across all groups. Additionally, hand therapy visits did not differ significantly between groups. Conclusions: Following extensor tendon repair, patient insurance status did not affect outcomes in terms of final range of motion, return to full activity, or postoperative complications.

Distal humeral osteotomy for cubitus varus in children compared to adolescents

BackgroundWhile pediatric cubitus varus has often been considered merely a cosmetic deformity, long-standing cubitus varus can lead to symptomatic pain and elbow instability in adults and may present as early as adolescence. The purpose of this study was to compare patient and radiographic characteristics, surgical factors, and symptom resolution after distal humeral osteotomy for cubitus varus in pediatric versus adolescent patients. MethodsThis is a retrospective single-institution review of 17 patients (12 patients <10.0 years (group Peds); 5 patients >10.0 years (group Adol)) were treated for cubitus varus with distal humeral osteotomy from 2003 to 2019. Peds had a median age of 6.3 years (range, 2.7-7.8 years) at the time of osteotomy, and Adol had a median age of 14.1 years (range, 13.5-16.7 years). A Fisher’s exact test was used to compare categorical variables between Peds and Adol, and continuous variables were compared using Mann-Whitney or Student’s t-test depending on normality results using the Shapiro-Wilk test. Statistical significance was set at P<.05. ResultsPreoperative pain was present in 17% (2/12) of Pediatric patients (Peds) but 100% (5/5) of Adolescent patients (Adols). Mechanical symptoms were present in 17% (2/12) of Peds and 80% (4/5) in Adol. Radiographic correction and final range of motion did not significantly differ between the 2 groups. The mean tourniquet time was 83 minutes in Peds and 117 minutes in Adol. Pin fixation was used in 100% (12/12) of Peds; 80% (4/5) of Adol had plates. At the final follow-up, all Peds had resolution of symptoms, but 60% (3/5) Adol had continued pain and mechanical symptoms. ConclusionsAlthough both pediatric and adolescent patients have similar radiographic correction and range of motion after distal humeral osteotomy to correct cubitus varus, the surgery may be more technically difficult in adolescent patients, with longer tourniquet times and the use of plate instead of pin fixation. Adolescents should be counseled that, like adults, their symptoms may not completely resolve after correction of radiographic and clinical deformity. The authors recommend that cubitus varus be corrected in childhood prior to the development of symptoms in adolescence. Key Concepts1)Cubitus varus following pediatric distal humerus fracture may present with pain and mechanical symptoms as early as adolescence.2)Although pediatric and adolescent patients may have similar radiographic correction and range of motion after distal humeral osteotomy, the surgery is technically more difficult in adolescent patients.3)Adolescents should be counseled that pre-operative symptoms may not completely resolve after correction of radiographic and clinical limb deformity.4)It is the authors’ opinion that cubitus varus should be surgically corrected before a child reaches adolescence, when it is technically less demanding and before mechanical symptoms and pain develop.

Distal radius fractures: What are the effects of ulnar styloid fracture and face-toface rehabilitation on the functional outcome?

This study aimed to investigate the effects of the accompanying ulnar styloid fracture and 2 different postoperative rehabilitation protocols on the final outcomes following surgical treatment of distal radius fractures. In this retrospective study, 47 patients (11 male, 35 female; mean age=52.6 years, age range=24-85) who underwent plate fixation for distal radius fractures were divided into 4 groups based on the presence of an ulnar styloid fracture and type of rehabilitation. To evaluate clinical outcomes, wrist range of motion (ROM), grip strength, lateral pinch strength, disabilities of the arm, shoulder, and hand (DASH) questionnaire scores and visual analog scale (VAS) scores were obtained at the final follow-up. The rehabilitation exercises of the patients in groups 1 and 2 were carried out in the physical therapy room by the hand therapist during the postoperative 2 months. Patients in groups 3 and 4 were supplied with videos of the exercises of each phase and instructed to carry out those exercises at home routinely. Patients who received home rehabilitation programs demonstrated greater grip strength loss. Patients without accompanying ulnar styloid fractures had better DASH and VAS scores. Final wrist ROM and the duration for return to preinjury activity level did not differ among groups. This study has suggested that accompanying ulnar styloid fractures may worsen the functional outcomes after plate fixation of distal radius fractures. Home-based programs may provide patients with adequate overall wrist function with certain drawbacks compared to rehabilitation under direct supervision.

Acute effects of resistance training at different range of motions on plantar flexion mechanical properties and force

ABSTRACT The effects obtained from resistance training depend on the exercise range of motion (ROM) performed. We aimed to examine the acute effects of different exercise ROM resistance training on the plantar flexor muscles. Eighteen healthy untrained male adults participated in three conditions: calf raises in 1) partial condition [final (short muscle length) partial ROM], 2) full condition (full ROM), and 3) control condition. The ankle dorsiflexion (DF) ROM, passive torque at DF ROM, passive stiffness of muscle-tendon unit, and maximal voluntary isometric contraction (MVC-ISO) torque were measured before and immediately after the interventions. There were significant increases in DF ROM, passive torque at DF ROM, and a decrease in MVC-ISO, but no significant interaction in passive stiffness. Post hoc test, DF ROM demonstrated moderate magnitude increases in the full condition compared to the partial (p = 0.023, d = 0.74) and control (p = 0.003, d = 0.71) conditions. Passive torque at DF ROM also showed moderate magnitude increases in the full condition compared to the control condition (p = 0.016, d = 0.69). MVC-ISO had a moderate magnitude decrease in the full condition compared to the control condition (p = 0.018, d=−0.53). Resistance training in the full ROM acutely increases joint ROM to a greater extent than final partial ROM, most likely due to stretch tolerance.

PATELLA FRACTURE FIXATION WITH NOVEL WAGON WHEEL CONSTRUCT VERSUS TENSION-BAND CONSTRUCT: A TECHNICAL TRICK.

Internal fixation of patella fractures remains technically challenging. Cannulated screws with an anterior tension band have been associated with high rates of implant prominence, and fracture comminution can make appropriate application of a tension band impractical. We present the results of a novel technique using a transtendinous/transligamentous mini-fragment plate positioned peripherally around the patella with radially directed screws: termed the wagon-wheel (WW) construct. Compared with a cohort of fractures treated with cannulated screws with an anterior tension band, there was no difference in final range of motion and rate of nonunion. The WW construct had a significantly decreased incidence of symptomatic implants (5% vs. 32%, P = 0.02), rate of reoperation (9% vs. 38%, P = 0.018), dependency on gait aids (10% vs. 38%, P = 0.031), and a faster time to union (HR: 2.2; 95% CI, 1.28-3.95, P = 0.005). In summary, the WW was designed with the goal of obtaining peripheral plate fixation to maximize fragment-specific fixation while minimizing implant prominence. Patients treated with the WW demonstrated reduced rates of implant prominence and reoperation.

Patient specific implants versus conventional implants in primary total knee arthroplasty: No significant difference in patient reported outcomes at 5 years

BackgroundPatient specific implants (PSI) represent a novel innovation aimed to improve patient satisfaction and function after total knee arthroplasty (TKA); however, longitudinal patient reported outcome measures (PROMs) for PSI are not well described. We sought to primarily evaluate PROMs of patients undergoing TKA with either PSI or off-the-shelf (OTS) implants at mid-term follow-up. MethodsA retrospective review was performed on a prospectively collected cohort of 43 primary, cruciate-retaining TKAs performed with PSI (n = 23) and OTS implants (n = 20) by a single surgeon. Patient demographics, operative characteristics, range of motion (ROM) return, reoperations, and outcomes [Patient-Reported Outcomes Measurement Information System (PROMIS) T-score, Knee Injury and Osteoarthritis outcome score (KOOS), and Knee Society Score-Function (KSS-F)] were compared. Mean follow-up was 5 years. ResultsTKA performed with either PSI and OTS implants demonstrated no difference in obtaining ROM by 3 months (extension 3° short of full extension vs. 0°, p = 0.16) or flexion (114° vs. 115°, p = 0.99) and final ROM was identical [0° extension to 120° flexion (p = 1)]. Although not significant (p = 0.42), 5 (22%) PSI TKA and 2 (10%) OTS implant patients required manipulation under anesthesia. KSS-F and PROMIS T-scores were higher in the PSI versus OTS TKA patients, respectively (90 vs. 73, p = 0.002; 51.6 vs. 44.5, p = 0.01). However, after multivariable analysis, none of these continuous outcome measures were significantly different (p = 0.28 for KSS and p = 0.45 for PROMIS T-score) between the groups. ConclusionIn a series of TKAs performed with PSI, no difference existed in postoperative ROM, reoperations, or patient-reported outcomes compared to OTS implants at 5 years. Surgeons may utilize the equivocal midterm results during TKA preoperative patient discussion of implant technologies.

Does tranexamic acid diminish hemorrhage and pain in open elbow arthrolysis? a systematic review and meta-analysis

Background/Objective: Effective hemostasis has the potential to reduce inflammation and pain, leading to potential benefits in the early rehabilitation of patients who undergo elbow arthrolysis. In the present study, we aim to assesse the effects of tranexamic acid (TXA) on elbow arthrolysis postoperative blood loss, patients’ pain perception according to the visual analog scale (VAS), elbow range of motion (ROM), and complications.MethodsWe systematically searched PubMed, Web of Science, SCOPUS, and Cochrane Library. We included controlled trials, either randomized (RCT) or non-randomized studies of intervention (NRSI) comparing the effects of intravenous tranexamic acid (TXA) treatment with placebo/no treatment on postoperative blood loss, pain VAS score, elbow ROM, and complications, in patients who underwent open or closed elbow arthrolysis surgery.ResultsOne RCT, and three NRSIs met eligibility criteria. The meta-analysis determined that tranexamic acid application reduced drain output 34 mm on average (WMD: -34.00; 95% CI: -49.45, -18.55). There was a discrepancy among included articles in terms of intra-operative blood loss; although the study with the largest sample size (291 and 296 patients in the case and control groups, respectively) reported reduced intra-operative blood loss in patients who received TXA. The pooled estimation for the pain VAS score on the first day post-operatively indicates a reduction in pain among patients in the TXA group (WMD: -0.82; 95% CI: -1.36, -0.28). Results for ROM, and complications’ rate such as hematoma and ulnar nerve palsy were not different between the two groups.ConclusionTXA may be beneficial to reduce elbow arthrolysis bleeding volume. However, it dose not seem to affect final elbow ROM and patients’ pain score. Further high-quality clinical trials are needed to draw a robust conclusion on this topic.
