education - Abstract
Internal rotation contracture of the shoulder in brachial plexus birth palsy frequently leads to shoulder dysplasia. Six children underwent anterior arthroscopic release sparing the subscapularis. Clinical examination and MRI were performed preoperatively and repeated at the 5-year follow-up. MRI was carried out for assessment of glenohumeral dysplasia. Passive external rotation was improved by 63.3° without any limitation of active internal rotation. Active antepulsion/abduction was improved by 90°. Remodeling of the glenoid and improved coverage of the humeral head were observed in all cases. Shoulder arthroscopic release sparing the subscapularis seems to be an efficient procedure to restore external rotation without affecting active internal rotation.

- Abstract
Purpose: To determine, from a sizable cohort of reverse shoulder arthroplasty (RSA), whether the deltopectoral (DP) or anterosuperior (AS) approach grant better outcomes at a minimum follow-up of 24 months., Methods: The authors reviewed 743 RSAs in patients with primary osteoarthritis (OA) with or without rotator cuff lesions and secondary OA due to rotator cuff tears. The DP approach was used in 540 and the AS approach in 203. Pre- and post-operative constant scores (CSs) and shoulder range of motion were recorded., Results: Of the initial cohort of 743 shoulders, 193 (25.7%) were lost to follow-up, 16 (2.1%) died, and 33 (4.4%) were revised; 540 shoulders were operated using DP approach (73%), of which 22 were revised (4.1%), while 203 were operated using the AS approach (27%), of which 11 were revised (5.4%). Propensity score matching resulted in two groups: 172 shoulders operated by DP approach, and 88 shoulders operated by AS approach. Comparing outcomes of the matched groups at 2 or more years also revealed that, compared to the AS approach, the DP approach resulted in significantly better post-operative CSs (67.3 ± 14.0° vs 60.8 ± 18.3, P = 0.017), active forward elevation (137° ± 27.4° vs 129° ± 29.8; P = 0.031)., Conclusion: At 2 or more years following RSA, the DP approach granted significantly better CS (by 6.5 points) and active forward elevation (by 8°) compared to the AS approach. The differences observed are clinically relevant and must be considered to manage patient expectations following RSA and for selecting surgical approach depending on their functional needs., Level of Evidence: III, comparative study., Competing Interests: Declaration of Conflicting Interests: CN and LH report fees from DePuy Synthes outside of the submitted work.

- Abstract
Background: Latissimus dorsi tendon transfer (LDTT) is increasingly performed with arthroscopic assistance, requiring an open axillary incision, which could increase risks of infection, hematoma, and lymphoedema. Technological advancements now enable LDTT to be fully arthroscopic, but its benefits and safety have not yet been confirmed., Purpose: To compare the clinical outcomes and complication rates of arthroscopic-assisted versus full-arthroscopic LDTT for irreparable posterosuperior massive rotator cuff tears in shoulders with no surgical antecedents., Study Design: Cohort study; Level of evidence, 3., Methods: The study included 90 patients who had undergone LDTT over 4 consecutive years by the same surgeon and did not have prior surgery. During the first 2 study years, all procedures were arthroscopically assisted (n = 52), while during the last 2 years, all procedures were fully arthroscopic (n = 38). Procedure duration and all complications were recorded, as well as clinical scores and range of motion at minimum 24-month follow-up. To enable direct comparison between the techniques, propensity score matching was used to obtain 2 groups with equivalent age, sex, and follow-up., Results: From the initial cohort of 52 patients who underwent arthroscopic-assisted LDTT, 8 had complications (15.4%), of which 3 (5.7%) required conversion to reverse shoulder arthroplasty and 2 (3.8%) required drainage or lavage. From the initial cohort of 38 patients who had full-arthroscopic LDTT, 5 had complications (13.2%), of which 2 (5.2%) required conversion to reverse shoulder arthroplasty but no patients (0%) required other procedures. Propensity score matching resulted in 2 groups, each comprising 31 patients, with similar outcomes in terms of clinical scores and range of motion. The procedure time was about 18 minutes shorter for full-arthroscopic LDTT, which had different complications (2 axillary nerve pareses) as compared with arthroscopic-assisted LDTT (1 hematoma and 2 infections)., Conclusion: Equivalent outcomes at minimum 24-month follow-up were found for arthroscopic-assisted and full-arthroscopic LDTT in terms of complications rates (15.4% and 13.2%, respectively), conversion to reverse shoulder arthroplasty (5.7% and 5.2%), clinical scores, and range of motion., Competing Interests: The authors have declared that there are no conflicts of interest in the authorship and publication of this contribution.

- Abstract
Background: Over time, surgical management for conditions involving the long head of the biceps tendon (LHBT) has evolved. Some techniques, such as keyhole tenodesis proposes bicortical drilling, however, carries an axillary nerve injury risk. The goal of our cadaveric study was to see if we could keep a safe zone between the point of exit of keyhole tenodesis of biceps and axillary nerve., Methodology: The study was performed on ten shoulders from five fresh frozen cadavers. Between the lower border of the transverse humeral ligament (THL) and the superior margin of the pectoralis major insertion at the lowest limit of the bicipital groove, a beath pin was driven through with the help of the modified tip aimer tibial jig procured from the anterior cruciate ligament reconstruction (ACL) set, which was fixed at an arc of 45°. The distance between the axillary nerve and beath pin at the exit point was measured., Results: The biceps tendon musculotendinous junction was followed all the way to the inferiorly and biceps tendon was found in the groove. The average distance from the axillary nerve to the exit point of the beath pin was 17.7 mm (range 14.4-20.9 mm, 95% CI)., Conclusion: The axillary nerve is not injured during bicortical drilling when keyhole tenodesis of biceps is performed at the distal limit of the groove of biceps. The area in the biciptal groove between inferior margin of THL and superior border of pectoralis major insertion is safe area for biceps tenodesis., Competing Interests: Conflict of InterestDr. Rajkumar S.

- Abstract
Purpose: To determine the reliability of anatomic references for mediolateral component positioning in shoulder arthroplasty., Materials and Methods: The computed tomography scans of 86 shoulders free of arthritic or anatomic deformities were studied. Two surgeons independently digitized a series of points, including the intersection of the 3 bone branches of the scapular spine (Y), the center of the glenoid surface (G), the most medial point of the scapula (MS), the cortical convergence (CC) of the anterior and posterior margins of the glenoid, the base of the coracoid (BC), the anterior (HA) and posterior (HP) margins of the subchondral bone., Results: The mean mediolateral distances between G and Y, BC, CC were respectively - 19.6 mm, - 1.5 mm, and - 36.8 mm. The consistency of anatomic landmarks was greatest for Y (standard deviation (SD) =2.3 mm; interquartile range (IQR) =3 mm), compared to BC (SD = 4.6 mm; IQR = 7 mm), and CC (SD = 6.6 mm; IQR = 8 mm). The repeatability of anatomic landmarks was excellent for all measurements. The mean ratios (relative to humeral head size) of distances between G and Y, BC, CC were respectively - 0.45, - 0.04, and - 0.85. The consistency of ratios was greatest for Y (SD = 0.05; IQR = 0.06), compared to BC (SD = 0.11; IQR = 0.14), and CC (SD = 0.13; IQR = 0.17). The repeatability of ratios was excellent for Y and BC, while it was good for CC., Conclusions: The Y-plane is a reliable reference for glenoid component positioning in shoulder arthroplasty, with a consistent distance from the center of the glenoid surface, and could therefore be suitable for preoperative planning., Study Design: Level III, comparative anatomic study., (© 2022.

- Abstract
Introduction: Osteoarthritis (OA) of the shoulder in under-50 year-olds is rare, and treatment is delicate. Shoulder replacement incurs frequent long-term risk of progression and a high revision rate, making it unsuited to young active patients. The aim of the present study was to determine the epidemiology of shoulder OA in under-50 year-olds and to assess the clinical results of the various treatment options., Hypothesis: The main study hypothesis was that well-conducted non-operative treatment can allow shoulder replacement to be postponed. The secondary hypothesis was that anatomic total shoulder arthroplasty (TSA) is the treatment of choice when other options fail., Materials and Methods: A multicenter retrospective study included primary (POA) and post-instability osteoarthritis (PIOA) in patients aged≤50years at symptom onset. Exclusion criteria comprised post-traumatic OA, rheumatoid arthritis and necrosis. Two hundred and sixty-six patients for 273 shoulders were included from 13 shoulder surgery centers: 2 types of non-operative treatment (28 by platelet-rich plasma [PRP] and 88 by viscosupplementation), 73 arthroscopies, and 150 implantations (62 humeral hemiarthroplasties [HA], comprising 10 hemi-metal, 24 hemi-pyrocarbon and 28 hemi-resurfacing; 77 anatomic total prostheses, and 11 reverse prostheses). Minimum follow-up was 12 months for non-operative treatment and 24 months for arthroplasty (some patients having both). Endpoints comprised Constant score, Subjective Shoulder Value (SSV) and number of complications/revision procedures., Results: Mean age at treatment was 43 years (range, 23-65 years), with 75% male predominance. Symptom onset was earlier in PIOA than in POA: 36 vs. 39 years (range, 20-50 years). PRP and viscosupplementation postponed implantation by a mean 3.5 years in 86% of cases, as did arthroscopy in 56%. ER1 restriction was the most negative factor. At 74 months' follow-up for HA and 95 months for TSA, mean Constant score was significantly lower for HA (56 vs. 67; p=0.004), with higher rates of complications (31% vs. 11%) and implant exchange (13% vs. 9%)., Discussion/conclusion: PRP, viscosupplementation and arthroscopy allow implantation to be postponed until the shoulder becomes stiff and painful. In case of failure, TSA is the most effective solution in the medium-term., Level of Evidence: IV a; therapeutic study - investigating the results of treatment., (Copyright © 2020 Elsevier Masson SAS.

- Abstract
Indications and techniques for tendon transfer in irreparable rotator-cuff tear have greatly progressed and are no longer restricted to external rotation deficit. The present article first reviews the various types of tear and corresponding tendon transfers and the biomechanics of the pseudoparalytic shoulder. The indication of choice for tendon transfer is iterative tear following failure of isolated long biceps tenotomy or partial repair. Latissimus dorsi, inferior trapezius and pectoralis major transfer are the 3 types to be used after failure of primary surgery. Latissimus dorsi transfer is indicated for partial loss of active limb elevation or isolated loss of internal rotation. Inferior trapezius transfer is best indicated for isolated active external rotation deficit. In pseudoparalytic shoulder with total loss of active elevation or combined loss of elevation and active external rotation, isolated transfer is insufficiently powerful to restore active range of motion and should be associated to reverse arthroplasty. We describe the various transfer techniques and report their results., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Kany J and Selim HA
- Abstract
Many treatment options have been proposed for treatment of irreparable posterosuperior rotator cuff tears. Among these options, latissimus dorsi tendon transfer can be considered a good alternative, especially in young patients before development of glenohumeral arthritic changes, aiming at rebalancing the shoulder with a functioning subscapularis muscle and restoring both active external rotation and elevation with the aid of a properly functioning deltoid muscle. The technique was recently adapted from open to arthroscopically assisted with numerous advantages. We propose a combined fully arthroscopic technique for transfer of latissimus dorsi and teres major in which the tendons are fixed in a flat manner at the junction of supraspinatus and infraspinatus to decrease failure rate., (© 2019 by the Arthroscopy Association of North America.

- Abstract
Background: Internal impingement of the shoulder (IIS) is the leading cause of chronic shoulder pain in overhead throwing athletes. No consensus exists about which techniques are optimal when surgery is in order. The available studies are limited by small sample sizes and short follow-ups. The primary objective of this study was to assess return-to-sports (RtS) outcomes after surgical treatment for IIS. A favourable RtS outcome (RtS+) was defined as returning to the previous sport at the same or a higher level., Hypothesis: The main hypothesis was that surgical treatment resulted in an RtS+ outcome. The secondary hypothesis was that epidemiological factors, pre- and intra-operative anatomical factors, and specific surgical procedures were associated with higher RtS+ rates., Material and Methods: A retrospective multicentre design was used. We included 135 patients with IIS managed arthroscopically using any of the following procedures: anterior capsulorrhaphy, posterior capsulotomy/capsulectomy, postero-superior labral debridement, posterior glenoidplasty, and rotator cuff tear debridement or repair. Follow-up was at least 1 year. The patients were divided into two groups based on whether they had an RtS+ outcome as defined above or an RtS- outcome defined as a return to the previous sport at a lower level, a switch to another sport, or an inability to engage in any sport. The Kerlan-Jobe Orthopaedic Clinic (KJOC) and Constant's score were used to evaluate subjective and objective shoulder function., Results: Mean follow-up was 7.9 years. Of the 135 patients, 120 (90%) returned to sports after surgery including 70 (52%) to the previous sport at the same level (RtS+ outcome). By univariate analysis, the following factors were associated with an RtS+ outcome: male sex, rotator cuff tear documented intra-operatively, absence of a greater tuberosity cyst on pre-operative imaging studies, and cuff tear debridement. Anterior capsulorrhaphy was associated with worse post-operative pain., Discussion: The RtS+ rate in this study differed from previously reported values, due to differences in the sports practiced by the patients and to considerable variability in the surgical techniques used. The positive association between presence of a rotator cuff tear and an RtS+ outcome is at variance with most of the previously published data. Some of the apparent discrepancies between our results and those from other countries may be ascribable to differences in the most popular sports., Level of Evidence: IV., (Copyright © 2019.

- Abstract
Background: Internal impingement of the shoulder (IIS) is a specific disorder of young overhead-throwing athletes that was first described in 1991. The many non-operative and surgical treatments suggested to date have produced mixed outcomes. The objective of this study was to compare the practices of surgeons in France versus other countries regarding the diagnosis and treatment of IIS., Hypothesis: Diagnostic and therapeutic practices regarding IIS differ between surgeons in France and in other countries., Material and Methods: A 21-item questionnaire in French and English was emailed to the 1300 members of the French Arthroscopy Society and to surgeons from countries other than France. The questionnaire collected information on knowledge about IIS (2 items), the frequency of IIS in clinical practice (2 items), the diagnosis of IIS (6 items), the non-operative and surgical treatment of IIS (3 and 5 items, respectively), and return-to-sports rates after treatment for IIS (3 items)., Results: The completed questionnaire was sent back by 261 surgeons, 206 in France and 55 in other countries, including 42 in Japan. Among the respondents, 90% knew about IIS. Experience with IIS in terms of number of patients seen or surgical treatments performed was greater in the international group (45% vs. 19% in France, p<0.001). Posterior shoulder pain in the arm cocking position was the most widely recognised symptom (99% in France, 74% internationally, p<0.001), followed by excessive external rotation during arm abduction (55% vs. 65%, p=0.23). The most commonly sought lesions were those of the postero-superior labrum and articular surface of the rotator cuff. Rotator cuff debridement was among the surgical options according to most respondents (74% vs. 70%). In contrast, postero-superior glenoidplasty was cited almost only by surgeons in France (67% vs. 4%, p<0.001). The proportion of patients who are able to return to sports was estimated at 50% to 75% by most respondents., Discussion: Most respondents had theoretical knowledge about IIS, but surgery was rarely performed in France. Only very few athletes in France play baseball, which is responsible for most sports injuries of the shoulder seen in Japan. This fact, combined with differences in the lesions or even the diagnoses, may have contributed to the differences in the responses to the survey items between the French and international groups., (Copyright © 2019 Elsevier Masson SAS.

19. Arthroscopic Coracoacromial Ligament Transfer Augmented With Suspensory V-Shaped Fixation System for Chronic Acromioclavicular Joint Dislocation.

Kany J and Selim HA
- Abstract
Chronic acromioclavicular joint dislocations (ACJDs) develop when there is failure of conservative treatment, failed surgical treatment of acute ACJD, or simply missing the treatment in the acute healing phase. There is wide agreement that mechanical fixation alone in chronic ACJD is not sufficient and biological augmentation is necessary. Various arthroscopic techniques for reconstruction of the coracoclavicular ligament have been described, but allografts are expensive, are not available in all centers, carry the risk of disease transmission, and are "dead tissue" with a poor capacity for healing. Autografts are associated with donor-site morbidity and avascular structures. Moreover, these grafts are associated with a high risk of clavicular or coracoid fractures owing to large tunnels. We present an arthroscopic technique to transfer the coracoacromial ligament to the inferior surface of the lateral part of the clavicle in chronic ACJD, augmented with 2 clavicular buttons and a single coracoid button in a V-shaped configuration. The technique has various advantages including better stabilization, anatomic reconstruction, and a minimal risk of fracture of the coracoid and clavicle with small tunnels, using a vascularized graft with arthroscopic control of reduction.

- Abstract
Background: No consensus exists about the management of massive and symptomatic rotator cuff tears (RCTs). The objective of this study was to compare the 12-month clinical outcomes of various treatment options for massive RCTs., Hypothesis: Arthroscopic surgery has a role to play in the treatment of massive and apparently irreparable RCTs., Material and Methods: A prospective multicentre non-randomised study was performed in patients with massive RCTs managed non-operatively (NONOP) or by arthroscopic tenotomy/tenodesis of the long head of biceps (aTLB), arthroscopic partial tendon repair (aPTR), arthroscopic latissimus dorsi transfer (aLDT), or reverse shoulder arthroplasty (RSA). Clinical outcomes were evaluated based on the Constant score, Subjective Shoulder Value (SSV), and American Shoulder and Elbow Surgeons (ASES) score after 3, 6, and 12 months., Results: The 218 included patients (mean age, 69 years) were distributed as follows: NONOP, n=71; aTLB, n=26; aPTR, n=61; aLDT, n=25; and RSA, n=35. After 12 months, the mean Constant score, SSV, and ASES score values were 70, 68%, and 73, respectively, and had improved significantly versus the preoperative values in all treatment groups. RSA was the only treatment followed by improvements in all Constant score items. Active forwards elevation improved significantly in the NONOP (+25°), aPTR (+26°), and RSA (+66°) groups. An improvement in active external rotation was seen only in the RSA group, where it was small (+10°, p=0.046). Significant increases in internal rotation were seen in the NONOP (+1.6 points) and aPTR (+1.7 points) groups., Conclusion: Arthroscopic techniques (aTLB, aPTR, and aLDT) for managing massive irreparable RCTs produce significant functional gains. Partial tendon repair (aPTR) and RSA may provide better outcomes than isolated aTLB or aLDT., Level of Evidence: III, non-randomised prospective study., (Copyright © 2018.

- Abstract
Background: Combination of fluoropyrimidines and a platinum derivative are currently standards for systemic chemotherapy in advanced adenocarcinoma of the stomach and gastroesophageal junction (GEJ). Nevertheless, individual likelihood for response to these therapeutic regimes remains uncertain. Even more, no predictive markers are available to determine which patients may benefit more from oxaliplatin versus cisplatin or vice versa. The new invasion and stem cell markers VEGFR-3 and CXCR4 have been linked prognostically with more aggressive esophagogastric cancer types. Thus, we aimed to assess correlations of VEGFR-3 and CXCR4 expression levels with clinical outcome in a randomized phase III study of patients with oxaliplatin/leucovorin/5-FU (FLO) versus cisplatin/leucovorin/5-FU (FLP)., Methods: The patients data examined in this study (n = 72) were from the collective of the FLO vs. FLP phase III AIO trial. Tumour tissues were stained via immunohistochemistry for VEGFR-3 and CXCR4 expression and results were evaluated by two independent, blinded investigators.Outcome parameter: Survival analysis was calculated for patients receiving FLO vs. FLP in relation to VEGFR-3 and CXCR4 expression., Results: 54% and 36% of the examined tumour tissues showed strong positive expression of VEGFR-3 and CXCR4 respectively. No superiority of each regime was detected in terms of overall survival (OS) in the whole population. Patients with strong expression of CXCR4 on their tumour tissues profited more in terms of OS under the treatment of FLP (mOS: 28 vs 15 months, p = 0.05 respectively). Patients with negative VEGFR-3 and CXCR4 expression had a trend to live longer when FLO regime was applied (mOS: 22 vs. 9 months, p = 0.099 and 20 vs. 10 months, p = 0.073 respectively). In an exploratory analysis of patients older than 60 years at diagnosis, we observed a significant benefit in overall survival for VEGFR-3 and CXCR4-positive patients when treated with FLP (p = 0.002, p = 0.021 respectively)., Conclusions: CXCR4 positive patients profited in terms of OS from FLP, whereas FLO proved to be more effective in CXCR4 and VEGFR-3 negative patients. Our results suggest, despite the limited size of the study, a predictive value of these biomarkers concerning chemotherapy with FLP or FLO in advanced esophagogastric cancer.

- Abstract
Latissimus dorsi tendon transfer is a method for surgical treatment of massive irreparable posterosuperior cuff tears. It partially restores active anteflexion, external rotation, and function of the shoulder but does not significantly increase strength of the shoulder. It is contraindicated in case of pseudoparalytic shoulder; associated irreparable subscapularis tear, deltoid palsy, and in case of associated osteoarthritis, as an isolated procedure. Results are inferior when performed as a secondary procedure compared with a primary procedure. However, latissimus dorsi tendon transfer is an attractive solution to improve shoulder mobility and function of young and non osteoarthritic patients whose previous surgical treatment of massive postero-superior irreparable rotator cuff tear failed. As a primary procedure, latissimus dorsi tendon transfer competes with debridement, biceps tenotomy, and partial cuff repair. In association with reverse shoulder arthroplasty, it restores active external rotation in osteoarthritic patients with active external rotation deficit. New arthroscopic assisted techniques might improve results in the future.

- Abstract
Arthroscopically assisted latissimus dorsi transfer is a viable option for treatment of patients in their 50s to 70s, without arthritis of the glenohumeral joint, who suffer from massive rotator cuff tears that are not amendable to primary repair due to fatty changes in the muscle tissue, or that have failed previous repair attempts. This procedure offers immediate and dramatic pain relief and is not as technically demanding as one might think. Understanding and respecting the principles of tendon transfer is a key to the success of this procedure.

- Abstract
We describe an arthroscopic keyhole technique for proximal biceps tenodesis. The technique is safe, easy to reproduce, cost-effective, and less time consuming. It does not need any special instrumentation and is suitable especially for use in the developing countries. It enables examination of the biceps sheath and distal biceps tendon for unidentified tears, synovitis, and fibrosis.
