Targeting the Sweet Spot: A Systematic Review With Meta-Analysis of Anterior Versus Posterior Glenohumeral Joint Injections for Adhesive Capsulitis.

To compare clinical outcomes following steroid injections using the anterior and posterior approaches. Systematic review with meta-analysis. Embase, Web of Science, and Cochrane Center Register of Controlled Trials were searched for randomized control trials (RCTs) and prospective comparative studies. Patients with adhesive capsulitis. Glenohumeral steroid injections using either anterior or posterior approach. Pain visual analog scale (VAS) and shoulder range of motion (ROM) at 12 weeks, accuracy, and adverse events. Standardized mean difference (SMD) for VAS and weighted mean difference (WMD) for ROMs. We identified 6 RCTs and one prospective comparative study with a total of 468 patients. While there was no difference in pain VAS at 12 weeks between the 2 approaches (SMD, -0.86; 95% CI, -1.76 to 0.04), the anterior approach resulted in greater improvements in external rotation (WMD, 8.08; 95% CI, 0.79-15.38) and abduction (WMD, 6.76; 95% CI, 3.05-10.48) compared with the posterior approach. Subgroup analysis with RCTs that utilized steroid injection with hydrodilatation for both approaches demonstrated greater reduction in pain VAS at 12 weeks with the anterior approach (SMD, -0.52; 95% CI, -0.98 to -0.07). Overall, procedures were well tolerated without major complications. While pain reduction is similar, the anterior approach may be more beneficial in restoring shoulder external rotation and abduction compared with the posterior approach at 12 weeks. Steroid injection combined with hydrodilatation may further improve pain control when performed with the anterior approach at 12 weeks.

Staged bilateral total shoulder arthroplasty: a single institutional experience with mid-term follow-up

BackgroundThe preferred surgical approach for surgical treatment of advanced glenohumeral arthritis is shoulder arthroplasty (SA). Considering the growing volume and success of SA, patients with bilateral shoulder disease are likely to undergo surgery on both shoulders. There are numerous studies evaluating the outcomes of bilateral hip and knee arthroplasty, but a paucity of information examining bilateral SA. This study intends to evaluate the clinical outcomes of patients undergoing staged bilateral anatomic total shoulder arthroplasty (aTSA) or reverse total shoulder arthroplasty (rTSA). MethodsInstitutional records were queried for patients who underwent staged bilateral aTSA or rTSA from 2009 to 2020. Patient records were retrospectively reviewed to assess preoperative and postoperative range of motion (ROM) and strength measurements, demographic information, and complications. Mean ± standard deviation was reported for all continuous variables. Mean functional measurements were compared using a 2-Sample t-Test, ordinal variables via Wilcoxon-Mann Whitney test, and categorical variables via Chi-squared test. Patients were included in the outcome analysis if they had a bilateral TSA with the same procedure (i.e. aTSA on both sides, or rTSA on both sides). Results43 patients (15 male, 28 female) were included. There was an average time of 1.8 years between surgeries. Of the 43 patients, 26 patients had staged bilateral aTSAs and 14 had staged bilateral rTSAs with three patients who had different surgeries on each shoulder. The three patients with different surgeries on each shoulder were excluded from outcome analysis. Patients who had staged aTSA operations demonstrated significant improvement in external rotation (P = .0191, P < .001), forward elevation (FE) (P = .0004, P < .001), and internal rotation (IR) (P = .0183, P = .0166) after the first and second surgeries. Staged rTSA patients showed significant improvement in FE after the first (P = .0043) and second surgeries (P = .016). Patients demonstrated significant increase in strength of external rotation (P = .0136), FE (P = .0088), and IR (P = .0206) after the first rTSA. There was no corresponding increase in strength testing after the second bilateral rTSA surgery. The average Single Assessment Numeric Evaluation, Contralateral Single Assessment Numeric Evaluation, American Shoulder and Elbow Surgeons, and Simple Shoulder Test scores for all surgeries were 84 ± 10, 83 ± 13, 75 ± 20, and 9 ± 2, respectively for the first surgery and 82 ± 13, 83 ± 13, 71 ± 21, and 8 ± 3 for the second surgery. ConclusionIndividuals that undergo staged aTSA procedures gain a better ROM and IR strength after both operations. However, individuals that undergo staged rTSA procedures have an improved ROM and strength after the first surgery but limited improvement after the second.

Clinical outcomes of over-the-top subscapularis repair in reverse shoulder arthroplasty

BackgroundBiomechanical research demonstrates increased subscapularis abduction range-of-motion (ROM) when the tendon’s upper two-thirds is repaired over-the-top of the center of rotation (OTTR) during reverse shoulder arthroplasty (RSA). This study compares clinical outcomes of patients undergoing RSA with OTTR to patients without repair. MethodsWe retrospectively reviewed 97 consecutive RSAs with either OTTR of the subscapularis (N=75) or no repair (N=22). Repair was attempted in all patients but not performed if the subscapularis could not be brought to the over-the-top position in 20° of external rotation and 30° of abduction. Improvements in ROM were compared to the minimal clinically important difference (MCID) for RSA. ResultsMean follow-up was 3.8±1.6 years. Demographics were similar between groups. Preoperatively, patients undergoing repair had greater external rotation when compared to those without repair (15±16°vs.5±12°,P=.003). Postoperatively, patients undergoing repair had greater forward elevation (132±21°vs.126±22°,P=.268) and abduction (114±26°vs.106±23°,P=.193) with both exceeding the MCID (-2.9°and-1.9°, respectively); however, not statistically significant. Patients with repair were more frequently able to reach the small of their back postoperatively (65%vs.21%, P=.006) but had less improvement in external rotation (13±20°vs. 24±20°,P=.028). Postoperative outcome scores, complications, and reoperations were similar between groups. DiscussionOTTR of the subscapularis in RSA had similar ROM and outcome scores compared to no repair, but a significantly larger proportion of patients with repair achieved functional internal rotation to the small of the back. External rotation limitations seen after conventional repair may also apply to this novel technique, but without a corresponding detrimental effect on forward elevation or abduction.

Does matching glenosphere size to patient height improve outcomes following reverse total shoulder arthroplasty?

Introduction Optimal biomechanics in reverse total shoulder arthroplasty (rTSA) are still a topic of debate. Although larger glenospheres have been linked with a theoretical improvement in the range of movement, results from clinical studies are mixed. We hypothesised that matching glenosphere diameter to patient height would result in greater improvements in post-operative range of motion (ROM) and patient-reported outcomes (PROMs). Methods An international database of rTSAs was analysed. After exclusions, 3318 rTSA patients were classified as short (&lt;158 cm), average (158–173 cm) or tall(&gt;173 cm). Outcomes were stratified for glenosphere size (small≤38 mm, large≥40 mm). Results were compared preoperatively and at 2 years. Results In short patients glenosphere diameter had no statistically significant impact on the degree of post-operative improvement for any ROM or PROM. Average height patients treated with small glenospheres had significantly more improvement in internal rotation (1.3 vs 1.0, p = 0.01), VAS pain (5.3 vs 4.8, p = 0.002), American Shoulder and Elbow Surgeons (47.8 vs 45.2, p = 0.03) and Shoulder Arthroplasty Smart (30.9 vs 28.2, p = 0.01) but significantly less improvement in constant score (31.7 vs 35.3, p = 0.009). Tall patients treated with small glenospheres had significantly more improvement in external rotation (21.2 vs 16.4, p = 0.01) and VAS pain scores (4.7 vs 4.3, p = 0.04). Conclusions While most significant differences favoured small glenospheres, the magnitude of these differences was small. Overall, patients of all heights can expect similar clinical improvements irrespective of glenosphere size.

Two-year clinical outcomes and complication rates in anatomic and reverse shoulder arthroplasty implanted with Exactech GPS intraoperative navigation.

We compared the 2-year clinical outcomes of both anatomic and reverse total shoulder arthroplasty (ATSA and RTSA) using intraoperative navigation compared to traditional positioning techniques. We also examined the effect of glenoid implant retroversion on clinical outcomes. In both ATSA and RTSA, computer navigation would be associated with equal or better outcomes with fewer complications. Final glenoid version and degree of correction would not show outcome differences. A total of 216 ATSAs and 533 RTSAs were performed using preoperative planning and intraoperative navigation with a minimum of 2-year follow-up. Matched cohorts (2:1) for age, gender, and follow-up for cases without intraoperative navigation were compared using all standard shoulder arthroplasty clinical outcome metrics. Two subanalyses were performed on navigated cases comparing glenoids positioned greater or less than 10° of retroversion and glenoids corrected more or less than 15°. For ASTA, no statistical differences were found between the navigated and non-navigated cohorts for postoperative complications, glenoid implant loosening, or revision rate. No significant differences were seen in any of the ATSA outcome metrics besides higher internal and external rotation in the navigated cohort. For RTSA, the navigated cohort showed an ARR of 1.7% (95% CI 0%, 3.4%) for postoperative complications and 0.7% (95% CI 0.1%, 1.2%) for dislocations. No difference was found in the revision rate, glenoid implant loosening, acromial stress fracture rates, or scapular notching. Navigated RTSA patients demonstrated significant improvements over non-navigated patients in internal rotation, external rotation, maximum lifting weight, the Simple Shoulder Test (SST), Constant, and Shoulder Arthroplasty Smart (SAS) scores. For the navigated subcohorts, ATSA cases with a higher degree of final retroversion showed significant improvement in pain, Constant, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), SST, University of California-Los Angeles shoulder score (UCLA), and Shoulder Pain and Disability Index (SPADI) scores. No significant differences were found in the RTSA subcohort. Higher degrees of version correction showed improvement in external rotation, SST, and Constant scores for ATSA and forward elevation, internal rotation, pain, SST, Constant, ASES, UCLA, SPADI, and SAS scores for RTSA. The use of intraoperative navigation shoulder arthroplasty is safe, produces at least equally good outcomes at 2 years as standard instrumentation does without any increased risk of complications. The effect of final implant position above or below 10° of glenoid retroversion and correction more or less than 15° does not negatively impact outcomes.

Clinical and Structural Outcomes of Arthroscopic Rotator Cuff Repair in Patients Over 75 Years Are Comparable to Those in Younger Patients: A Propensity Score-Matched Comparative Study

PurposeTo compare clinical and structural outcomes of arthroscopic rotator cuff repair (ARCR) in patients over 75 years and those under 75 years and to analyze the factors associated with retear and clinical outcomes after ARCR. MethodsThis retrospective study reviewed patients who underwent ARCR between 2011 and 2021 with at least 2-years of follow-up. Using propensity score matching for sex, tear size, subscapularis involvement, and follow-up time, this study included 54 patients older than 75 years (group A) and 54 patients younger than 75 years (group B). Cuff integrity was evaluated using magnetic resonance imaging (MRI). Structural and clinical outcomes were compared between the two groups. ResultsThe mean improvements in external rotation (P = .030) and the ASES score (P = .043) were significantly higher in group A. Visual analog scales for pain and function, American Shoulder and Elbow Surgeons (ASES) score, and Constant score were significantly improved in both groups (all P = .001). On routine postoperative MRI at 6 months, the retear rate was 20.4% (11/54) in group A and 18.5% (10/54) in group B with no statistical difference between the two groups (P = .808). Factor analysis in group A showed that follow-up duration (P = .019), tear size in mediolateral dimension (P = .037), occupation ratio (P = .036), and incomplete repair (P = .034) were associated with retear, and mild glenohumeral arthritis (P = .003) and subscapularis involvement (P = .018) were associated with inferior Constant score. ConclusionClinical and structural outcomes after ARCR in patients aged 75 years or older are comparable to those in patients younger than 75 years.

Mid-term outcomes of arthroscopically assisted lower trapezius tendon transfer using Achilles allograft in treatment of posterior-superior irreparable rotator cuff tear

Arthroscopically assisted lower trapezius tendon (aLTT) transfer is one of the treatment options for posterior-superior irreparable rotator cuff tears (PSIRCTs). Although short-term clinical outcomes have shown promising results, there are currently no reported clinical outcomes over a longer follow-up period. This study evaluated the mid-term outcomes of aLTT transfer in patients with a diagnosis of PSIRCT. This retrospective case-series study included patients who underwent aLTT transfer between May 2017 and May 2019. The clinical outcome assessment included the visual analog scale (VAS) pain score, Constant score, American Shoulder and Elbow Surgeons score, University of California-Los Angeles score, Activities of Daily Living Requiring Active External Rotation (ADLER) score, active range of motion, Single Assessment Numeric Evaluation score, and return-to-work rate. The radiographic analysis included the acromiohumeral distance, Hamada grade, and integrity of the transferred tendon at final follow-up. Subgroup analyses were performed based on the integrity of the transferred tendon and the trophicity of the teres minor (Tm). This study enrolled 36 patients with a mean age of 63.4 years who met the inclusion criteria and were followed up for a mean of 58.2±5.3 months. At final follow-up, the patients showed significant improvement in mean VAS score, Constant score, American Shoulder and Elbow Surgeons score, University of California-Los Angeles score, ADLER score, and active range of motion in all directions except internal rotation. A decrease in the acromiohumeral distance and an increase in the Hamada grade were observed at final follow-up (P=.040 and P=.006, respectively). Retears of the transferred tendon occurred in 7 patients, and postoperative infections developed in 2 individuals. An interesting finding was that the retear group still demonstrated improvement in the VAS score but did not show improvement in external rotation at the side by the final follow-up. Compared with the Tm non-hypertrophy group, the Tm hypertrophy group showed significantly better improvement in external rotation at 90° of abduction and at the side, as well as the ADLER score. Of the study patients, 30 (83.3%) were able to successfully resume their previous work. In this study, aLTT transfer in patients with PSIRCTs demonstrated significant improvements in clinical and radiologic outcomes by the final follow-up. These findings provide support for the mid-term safety and effectiveness of aLTT transfer as a viable joint-preserving treatment option for PSIRCTs. However, larger and longer-term studies are still needed to further validate these findings.

Comparison of the Functional OutcomeBetween Intra-Articular Corticosteroid Injection versus Platelet-Rich Plasma in Patients with Adhesive Capsulitis

Objective: To compare mean resting pain relief and passive external rotation improvement by Intra-articular Steroid versus intra-articular Platelet Rich Plasma injection in patients with adhesive capsulitis.&#x0D; Study Design: Prospective comparative study.&#x0D; Place and Duration of Study: Armed Forces Institute of Rehabilitation Medicine, Rawalpindi Pakistan, from Jan to Jun 2019.&#x0D; Methodology: A total of 60 patients were included in the study. Group-A and B received Intra-articular 40mg Triamcinolone Acetonide with 1 ml 1% Lignocaine and platelet-rich plasma injections in affected shoulders, respectively. Pain severity was assessed on the Numeric Rating Scale, and passive external rotation was assessed by goniometry at baseline, i.e., preintervention, six weeks and 12 weeks intervals.&#x0D; Results: In our study, the NRS scale for pain was 3.030.76 at six weeks and 1.230.77 at 12 weeks with PRP versus 5.070.87 at six weeks and 3.200.89 with Corticosteroids at 12 weeks post-intervention, with the p-value of &lt;0.001 showing increased efficacy of PRP. While passive external rotation was 70.275.26 at six weeks and 82.304.84 at 12 weeks with PRP versus 61.35.28 at six weeks and 71.806.99 with corticosteroids at 12 weeks post-intervention, with the p-value of &lt;0.001 showing increased efficacy of PRP.&#x0D; Conclusion: There was a significant improvement in mean resting pain relief and passive external rotation after platelet-rich plasma injection in the shoulder joint adhesive capsulitis compared to intra-articular Steroids.

Comparison of Anterior and Posterior Transfer of Latissimus Dorsi Tendon to Humeral Head in Patients with Massive and Irreparable Rotator Cuff Tear.

Latissimus dorsi tendon transfer is a treatment option in patients with irreparable rotator cuff tears. This study aimed to compare the effectiveness and safety of anterior and posterior transfer of latissimus dorsi tendon for anterosuperior or posterosuperior massive irreparable rotator cuff tears. In this prospective clinical trial, 27 patients with irreparable rotator cuff tears were treated with latissimus dorsi transfer. The transfers in 14 and 13 patients were from the anterior for anterosuperior cuff deficiency (group A) and from the posterior for posterosuperior cuff deficiency (group B), respectively. Pain, shoulder range of motion in forward elevation, abduction, external rotation, and functional scores were evaluated 12 months after the surgery. Two and one patients were excluded from the study due to not referring in time for follow-up and infection, respectively. Therefore, 13 patients remained in group A and 11 patients in group B. Visual analog scale scores decreased from 6.5 to 3.0 in group A (P=0.016) and from 5.909 to 2.818 in group B (P=0.028). The constant scores improved from 41 to 50.2 (P=0.010) in group A and from 30.2 to 42.5 (P=0.001) in group B. There was a significant improvement in the abduction and forward elevation in both groups which was more significant in group B. The posterior transfer made significant improvement in external rotation; however, the anterior transfer did not change external rotation. No radial or axillary nerve injury was observed in any of the two groups. Latissimus dorsi transfer in patients with irreparable rotator cuff tears has a significant effect on recovery. It improves shoulder function and range of motion and reduces pain. Improvement of shoulder elevation and abduction is more significant in posterior transfer. The anterior transfer is as safe as the posterior transfer for nerve injury.

Optimizing glenoid bone preservation in reverse total shoulder arthroplasty using augmented baseplates

As techniques and implants for reverse total shoulder arthroplasty (rTSA) evolve, a greater emphasis is being placed on preserving glenoid bone stock and optimizing shoulder biomechanics. Augmented baseplates preserve glenoid bone and improve shoulder range of motion by lateralizing the center of rotation of the glenosphere, while also reducing postoperative complications after rTSA. The technique for bone preservation with use of augmented baseplates in the absence of bone loss and the outcomes of a series of cases are contained in this report. A retrospective chart review was conducted for 37 patients with Walch type A1/Sirveaux E0 glenoids who underwent primary rTSA using a bone preserving technique with an augmented baseplate between January 2018 and January 2019 at a single site by a single surgeon. The primary outcome measures were range of motion, strength, and patient-reported clinical outcomes (pain and function rated on a visual analog scale; single assessment numeric evaluation; American Shoulder and Elbow Surgeons score; and disabilities of the arm, shoulder, and hand score). Preoperative radiographs were analyzed for the presence of glenoid bone loss and postoperative radiographs were assessed for evidence of component loosening and scapular notching. A repeated measures design was used, and preoperative and postoperative comparisons were made using parametric t-tests. At an average follow-up of 23.3 ± 6.3 months, there was a significant improvement in active forward flexion and abduction and nonsignificant improvement in external rotation. There was no radiographic evidence of glenoid notching in any of the patients and optimal glenoid inclination was observed. Patient-reported outcome scores after an average of 25.2 ± 10.0 months indicated a significant improvement in pain, function, and scores for the American Shoulder and Elbow Surgeons and disabilities of the arm, shoulder, and hand assessments. There were no substantial postoperative radiographic findings, intra/postoperative complications, or revisions/reoperations. rTSA with augmented baseplates for glenoid bone preservation in patients with minimal or no bone loss is effective for preserving glenoid bone stock and significantly improves the range of motion and patient-reported outcomes after approximately 2 years.

Medialized versus Lateralized Center of Rotation in Reverse Total Shoulder Arthroplasty: A Systematic Review and Meta-Analysis.

One of the original biomechanical principles of reverse total shoulder arthroplasty (RTSA) is medialization of the center of rotation (COR) relative to the native level of the glenoid. Several authors have proposed the lateralized center of rotation, which is characterized by a lateralized (L) glenoid and medialized (M) humeral component. The aim of this review is to compare the clinical and functional outcomes of COR in medialized (M-RTSA) and lateralized (L-RTSA) RTSA in patients with uniform indications and treatment through a meta-analysis. A PRISMA-guided literature search of PubMed, Medline, Embase, Scopus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and Cochrane Clinical Answers was conducted from April to May 2021. Twenty-four studies were included in the qualitative synthesis, and 19 studies were included in the meta-analysis. Treatment with RTSA resulted in positive post-operative outcomes and low complication rates for both groups. Statistically relevant differences between L-RTSA group and M-RTSA group were found in post-operative improvement in external rotation with arm-at-side (20.4° and 8.3°, respectively), scapular notching rates (6.6% and 47.7%) and post-operative infection rates (1% and 7.7%). Both lateralized and medialized designs were shown to improve the postoperative outcomes. Nevertheless, a lateralized COR resulted in greater post-operative external rotation.

Rate of improvement in shoulder strength after anatomic and reverse total shoulder arthroplasty.

BackgroundThe rate at which patients regain shoulder strength after anatomic and reverse total shoulder arthroplasty (TSA) is unknown. In this study, we aimed to quantify differences in the timeline during which patients gained shoulder strength after primary anatomic and reverse TSA.MethodsWe retrospectively reviewed prospectively collected data from 374 shoulders after primary anatomic TSA (aTSA) and 601 shoulders after primary reverse TSA (rTSA). Postoperative improvement in external rotation (ER) strength and forward elevation (FE) strength from baseline was assessed at 3 months, 6 months, 1 year, and 2 years. Percent change in mean shoulder strength between each time point was determined for anatomic and reverse groups separately. A handheld dynamometer was used to assess ER strength with the involved shoulder in 0° ER, 0° abduction, and the elbow in 90° flexion and FE strength with the involved shoulder in the scapular plane at 30° of flexion and 30° of abduction.ResultsBoth aTSA and rTSA groups ceased to have statistically significant gains in FE strength after 1 year postoperatively. In contrast, patients continued to have statistically significant gains in ER strength between 1 year and 2 years postoperatively after rTSA (P = .001), but not after aTSA (P = .476). Both aTSA and rTSA groups saw improvement in strength in both ER (+32.1% and +51.4%, respectively) and FE (+38.3% and +90.3%, respectively) at 2-year follow-up. The aTSA group’s ER and FE strength increased the most between 3 and 6 months (+16.2% and +35.7%, respectively). In contrast, the rTSA group gained the most ER strength between 6 months and 1 year (+14.8%) and the greatest FE strength between baseline and 3 months (+40.3%).ConclusionPatients gain ER strength earlier and FE strength later after aTSA compared with rTSA. Most gains in strength occurred in the first year. However, statistically significant gains in shoulder ER strength in the rTSA group continued between 1 year and 2 years postoperatively, suggesting that 2-year follow-up may be inadequate to capture the full benefits of rTSA on shoulder strength. The results of this study provide insight into the timeline of strength recovery after aTSA and rTSA that will help inform patient counseling and future study design.

Long-Term Hand Function Outcomes of the Surgical Management of Complete Brachial Plexus Birth Injury

Hand function outcomes of primary nerve reconstruction for total brachial plexus birth injury (BPBI) are confounded by nerve roots left in continuity, inclusion of secondary procedures, and no assessment of the ability to perform activities of daily living. The purpose of this study was to evaluate the long-term hand function outcomes in a cohort of patients with a complete BPBI who had no nerve root in continuity prior to primary nerve reconstruction targeting the lower trunk. This single-center retrospective case series of complete BPBI included patients who underwent primary nerve reconstruction. The outcomes were assessed using the active movement scale (AMS) and brachial plexus outcome measure preoperatively and at the age of 4 and 8 years. Fifty patients with a complete BPBI, of whom 82% (41/50) had an avulsion of C8-T1, underwent primary nerve reconstruction at a mean age of 4.1 months. Compared with the preoperative AMS scores, a statistically significant increase of AMS scores was observed at 4 and 8 years of age for all movements except forearm pronation. Between 4 and 8 years of age, there was a statistically significant improvement of external rotation of the shoulder and elbow flexion as well as diminution of thumb flexion. In the brachial plexus outcome measure assessment, there were 83% (24/29) at 4 years and 81% (21/26) at 8 years who had sufficient functional movement to perform wrist, finger, and thumb activities. Functional hand outcome was restored to sufficiently perform bimanual activity tasks in 81% (21/26) of patients with a complete BPBI at 8 years of age. This affirmed that primary nerve reconstruction reinnervating the lower trunk can result in a functional extremity. Therapeutic IV.

Mid-term outcomes after reverse total shoulder arthroplasty with latissimus dorsi transfer.

Reverse total shoulder arthroplasty is a common treatment for patients with rotator cuff arthropathy who have failed a prior rotator cuff repair. Latissimus dorsi transfer can be performed simultaneously to reverse total shoulder arthroplasty for patients with preoperative external rotation deficiency. Current literature is limited with several studies providing functional and pain improvements at short-term follow-up; however, there is a deficit in data regarding mid-term outcomes. The purpose of this study was to evaluate the clinical and radiographic outcomes following reverse total shoulder arthroplasty with latissimus dorsi transfer with mid-term follow-up. We hypothesized significant improvement in external rotation and shoulder functionality for patients with preoperative external rotation lag. We retrospectively reviewed patients who underwent reverse total shoulder arthroplasty with latissimus dorsi transfer. Preoperative and postoperative changes in range of motion were assessed. American Shoulder and Elbow Surgeon Score and the Simple Shoulder Test were used to evaluate changes in shoulder function while pain scores were assessed using the Visual Analog Scale (VAS). Radiographs were reviewed for rotator cuff arthropathy, fatty infiltration, scapular notching, baseplate loosening, and osteolysis. We reported frequency and mean ± standard deviation for categorical and continuous variables, respectively. Means were compared using the paired Student's t-test and proportions using the Chi-square test. Fifteen patients met the inclusion criteria. The mean age of the cohort was 71.7 ± 8.4 years (range 51.2-87.8 years) with a mean follow-up of 6.3 ± 4.1 years (range 1.0-14.5 years). Reverse total shoulder arthroplasty with latissimus dorsi transfer improved external rotation (-7 ± 21.3° to 38 ± 15.8°; p value = 0.001). There was no statistically significant difference regarding forward flexion (116.3 ± 45.4° to 133.7 ± 14.7°; p value = 0.17) and internal rotation (T12 to L2; p value = 0.57). The procedure led to an increase in American Shoulder and Elbow Surgeon Score scores (37 ± 19 to 62 ± 22; p = 0.005) and Simple Shoulder Test scores (2 ± 2 to 6 ± 3; p value = 0.001) with a significant reduction in Visual Analog Scale scores (5 ± 3 to 2 ± 3; p value = 0.022). The procedure corrected external rotation lag in 10 patients. Radiographically, rotator cuff arthropathy was found to be grade 3 in two patients, grade 4 A in four patients, grade 4B in eight patients, and grade 5 in one patient. On postoperative imaging, scapular notching was found in six patients (40%). Twelve patients had cortical humeral erosion at the site of the latissimus dorsi transfer. Only one patient experienced a shoulder-related complication which was aseptic baseplate loosening and required a revision reverse total shoulder arthroplasty with allograft. In this study, patients undergoing reverse total shoulder arthroplasty with latissimus dorsi transfer experienced improvements in range of motion, functional scores, and pain at mid-term follow-up. The shoulder-related complication rate was low.Level of evidence: IV; Case series.

Latissimus Dorsi Tendon Transfer and Superior Capsular Reconstruction for Irreparable, Posterosuperior Rotator Cuff Tears.

The purpose of this study was to compare latissimus dorsi tendon transfer (LDTT) and arthroscopic superior capsular reconstruction (SCR) to determine if one is superior to the other regarding improvement in range of motion (ROM) or patient-reported outcomes (PROs). A multicenter, retrospective cohort study was conducted on 43 patients with an irreparable, posterosuperior rotator cuff tear who underwent either LDTT or SCR. Preoperative and postoperative forward flexion and external rotation, as well as PROs including ASES, VAS, and SSV, were assessed. Student t-test and chi-square statistical analyses were performed. 16 LDTT, at mean follow-up of 18 months, and 27 SCR, at mean follow-up 15 months, were studied. Mean active forward flexion significantly improved from 85.2° to 137.6° in the SCR cohort (P=0.001). SCR patients demonstrated a significantly greater increase in forward flexion as compared to LDTT patients (52.4° vs 14.1°, P=0.001). Mean active external rotation amongst the LDTT group significantly improved from 41.7° to 61.5° (P=0.032). LDTT demonstrated significantly greater improvement in external rotation as compared to SCR (19.4° vs 0.8°, P=0.011). There were no significant differences in reported ASES, VAS, or SSV scores. This study demonstrates successful clinical and patient-reported outcomes with both LDTT and SCR for irreparable, posterosuperior rotator cuff tears, with greater improvement in forward flexion with SCR and greater improvement in external rotation with LDTT.

Restoration of External Rotation Following a Lateral Approach for Glenoid Bony Increased-Offset Reverse Shoulder Arthroplasty

Background:Reverse shoulder arthroplasty (RSA) is a recognized therapeutic modality for a massive rotator cuff tear. Some authors recommend lateralization of the center of rotation by bony increased offset (BIO) of the glenoid for improvement of external rotation, while others refute its effects. RSA through the conventional deltopectoral approach sacrifices the subscapularis tendon during the approach. We hypothesized that a lateral approach (LA) for RSA, with less soft-tissue resection, would restore external rotation by allowing retensioning of the remaining rotator cuff with use of a BIO graft.Methods:We retrospectively investigated 36 nonlateralized inlay RSAs performed through a lateral approach (LA non-BIO group) and 40 inlay RSAs performed through a lateral approach with BIO (LA BIO group) for a massive rotator cuff tear. There were 5 patients with a combined loss of active elevation and external rotation (CLEER) in the LA non-BIO group and 6 in the LA BIO group. The Constant score, the UCLA (University of California Los Angeles) score, and range of motion, in particular, external rotation with the arm at 0° (ER0) and at 90° of abduction (ER90), were compared.Results:The mean ER90 in the LA BIO group improved significantly, from 45.8° ± 21.6° to 65.9° ± 15.8° (p = 0.012). Postoperative ER90 in the LA BIO group was significantly higher than in the LA non-BIO group (mean, 65.9° ± 15.8° compared with 53.0° ± 12.3°; p = 0.026). The mean ER0 for the patients with CLEER status significantly improved in the LA BIO group, from −15.8° ± 9.8° to 11.0° ± 15.6° (p = 0.0072). The mean postoperative anterior elevation, UCLA score, and Constant score in the LA BIO group and the LA non-BIO group improved significantly, but there was no difference between the 2 groups (anterior elevation: 131.5° ± 17.6° compared with 121.5° ± 14.1°, p = 0.07; UCLA: 25.5 ± 6.4 compared with 23.4 ± 5.4, p = 0.2; Constant: 74.3 ± 12.0 compared with 73.6 ± 10.1, p = 0.43).Conclusions:LA BIO-RSA was associated with a significant improvement in range of motion, particularly external rotation. Improvements in anterior elevation, the Constant score, and the UCLA score were not significantly different from those noted for LA non-BIO-RSA.Level of Evidence:Therapeutic Level III.

Clinical and Radiographic Outcomes After Arthroscopic Iliac Bone Grafting for Traumatic Anterior Shoulder Instability with Significant Glenoid Bone Loss – A Minimum of Five-year Follow-up

Objectives:The choice of surgical options for traumatic anterior shoulder instability with severe glenoid bony defect remains controversial. The purpose of this study was to evaluate the outcomes after arthroscopic (AS) iliac grafting with capsulolabral reconstruction with a minimum of five-year follow-up.Methods:Subjects consisted of 24 patients (24 shoulders), including 22 males and 2 females, who underwent AS iliac bone grafting and were followed for more than five years. Eighteen shoulders were primary surgery, and 6 were revision surgery. The mean age at surgery was 30 years (range, 18-52), and the mean follow-up was 8 years (range, 5-11). The mean glenoid bony defect measured on preoperative 3D-CT was 22% (range, 20-28). All surgeries were performed under general anesthesia. Free bone graft with approximately 2.0 cm length and 0.8 cm height was harvested from the iliac crest with the patients in the supine position, (Figure 1) and then the patient was placed in the beach chair position. The bone graft was inserted in the glenohumeral joint and arthroscopically fixed to the anterior glenoid using 2 cannulated screws followed by soft tissue Bankart repair using four anchors. (Figure 2 Gr: graft GL: glenoid) Functional outcomes including Rowe score, sports return, and ROM were evaluated. Radiographic findings including Samilson osteoarthritis (OA) grade and graft evaluation using 3D-CT at the final follow-up were also evaluated.Results:No patients experienced re-dislocation after surgery except one patient. All patients returned to their sports after surgery except for one patient who was not engaged in any sports. The mean Rowe score improved significantly from 19 (range, 5-40) to 95 (range, 70-100) (p<.0001). Postoperative forward flexion showed significant improvement: 157 (range, 110-180) to 170 (range, 150-180) degrees (p=.006), but no improvement in external rotation: 56 (range, 30- 85) to 56 (range, 30-70) degrees, and internal rotation: T8 (range, T5-L5) to T10 (range, T7-L5) level. OA change progressed in 8 shoulders (40%). 3DCT at the final follow-up demonstrated remodeling of the graft in 20 shoulders (88%) and absorption in 3 shoulders (12%).Failure case: A 23-year-old male experienced re-dislocation of the left shoulder during snowboarding five-year after the index surgery. Healed graft fracture and screw breakage were confirmed on 3DCT images (Figure 3).Conclusion:AS iliac bone grafting for traumatic anterior shoulder instability with significant glenoid bone loss yielded a satisfactory outcome with a minimum of five-year follow-up. Although this is technically demanding procedure, AS iliac bone grafting with capsulolabral reconstruction for shoulders with severe glenoid bone loss is an effective and practical procedure.Figure 1.Figure 2.Figure 3.

Bilateral total shoulder arthroplasty: A systematic review of clinical outcomes.

The purpose of this study was to describe the clinical outcomes following bilateral total shoulder arthroplasty (TSA). A systematic search of the PubMed, Embase, and Cochrane Library databases following PRISMA guidelines was performed. English-language literature published from 2010 to 2018 analyzing bilateral TSA (anatomic and/or reverse) with a minimum one-year follow-up was reviewed by two independent reviewers. Study quality was evaluated with the Modified Coleman Methodology Score and the methodological index for non-randomized studies score. Eleven studies (1 Level II, 3 Level III, 7 Level IV) with 292 patients were included. Two studies reported on bilateral anatomic TSA (n = 54), six reported on bilateral reverse TSA (RTSA; n = 168), two reported on anatomic TSA with contralateral RTSA (TSA/RTSA; n = 31), and one compared bilateral anatomic TSA (n = 26) and bilateral RTSA (n = 13). Among studies, mean revision rate ranged from 0% to 10.53% and mean complication rate ranged from 4.9% to 31.3%. At final follow-up, patients experienced significant overall improvements in range of motion and patient-reported outcome score measurements. However, bilateral anatomic TSA resulted in greater improvements in external rotation compared to bilateral RTSA. Overall patient satisfaction was 91.0%. The available data indicate that bilateral TSA allows for functional and pain improvements and result in high patient satisfaction. IV.

Arthrolyse arthroscopique dans les raideurs de l’épaule séquellaires de paralysie néonatale du plexus brachial: Résultats cliniques d’une série prospective de 28 enfants sur 2 ans de suivi

The primary objective of this study was to evaluate improvements in external rotation after isolated arthroscopic capsular release in children with shoulder contracture due to brachial plexus birth palsy. This study included all children older than 2 years with a range of active external rotation limited to 30° or less and/or active anterior elevation (AE) limited to 90° or less secondary to brachial plexus palsy treated between 2011 and 2015. Passive glenohumeral motion, passive global (gle- nohumeral plus scapulothoracic) motion, active global motion for external rotation with the elbow at the side (ER1), AE, and internal rotation with the elbow at the side were recorded before and 2 years after surgery. Improvement was evaluated by comparing the preoperative and follow-up values. The operation performed was subscapularis-sparing arthroscopic capsular release. Thirty-five patients were included, and 28 completed 2 years of follow-up. The average changes in active global ER1, passive glenohumeral ER1, and passive global ER1 were + 35 (range, 20 to + 100; p > 0.0001), + 35 (range, + 0 to + 75°; p > 0.0001), and + 26° (range, 15 to + 60; p > 0.0001), respective- ly. There were no significant changes in internal rotation with the elbow at the side or AE. The mean improvement in the aggregate Mallet score was 3.9 points (range,?3 to + 9 points; p > 0.0001). For children with shoulder contracture secondary to brachial plexus palsy, subscapularis- sparing isolated capsular release improves external rotation and functional scores and avoids any loss of active internal rotation but does not improve AE.

Clinical and cost comparison of manipulation under anaesthetic and steroid injection for frozen shoulder (stage II) with arthroscopic interval release

BackgroundManipulation under anaesthetic and Steroid Injection (MUA) is a traditional treatment for frozen shoulder (FS). Some clinicians believe arthroscopic release is superior. This study evaluates the clinical outcome of MUA for primary unilateral stage II FS and compared costs to interval release (IR). Methods115 cases were retrospectively reviewed. Pre- and postoperative ranges of movement (ROM) were measured and compared to the other shoulder. Demographic data, symptom length, stated cause and diabetic status (11) were collected. Postoperative course was charted to discharge. ResultsFinal ROM matched the normal side for flexion and abduction with significant improvement of external rotation (6.5° (SD 8.9°)) and internal rotation (1.3 vertebra/10 (SD1.6)). No pre-existing factors investigated influenced the results. 3 failures (2.6%), had repeat MUA (2) or IR (1). 73 were discharged on first post-op visit (63.5%). 27 (23%) had mild shoulder impingement that resolved with steroid injection, 3 (2.6%) with impingement required SAD, 9 (7.8%) with mild residual stiffness, which settled spontaneously. There were no complications.MUA took 16 min, generated income £1600 with cost £831. IR took 66 min, income £4163, cost £2931. ConclusionMUA for FS is safe, successful (97%) obtaining near normal movement (94%). It is a cost effective first line treatment for patients, hospital and NHS. Symptomatic shoulder impingement is common postoperatively and should be sought and treated.
