Outcomes of Isolated Biceps Tenodesis/Tenotomy or Partial Rotator Cuff Repair Associated with Biceps Tenodesis/Tenotomy for Massive Irreparable Tears: A Systematic Review.

Irreparable large to massive rotator cuff tears (MIRCTs) are a prevalent cause of shoulder pain and dysfunction, and nonoperative treatment may not always be effective. Various surgical options exist, with isolated biceps tenotomy/tenodesis (BT) or arthroscopic partial repair with associated biceps tenotomy/tenodesis (PCR-BT) being the most common. The aim of this study was to systematically review the available data on the clinical and functional outcomes of BT and PCR-BT in patients with MIRCTs. METHODS: MEDLINE, Embase, and CENTRAL databases were searched for studies on the treatment of MIRCT. We included studies with BT or PCR-BT with a minimum follow-up of 24 months. The MINORS (Methodological Index for Nonrandomized Studies) score was used to assess study quality. Outcomes included were the visual analog scale for pain, functional scores such as Constant-Murley and American Shoulder and Elbow Surgeons, range of motion, radiological measurements, and complications. RESULTS: A total of 1101 patients (506 had a BT and 595 had a PCR-BT) from 22 studies were included (cases series = 13, case-control = 7, randomized control trial = 1, prospective cohort study = 1). The mean MINORS score was 13.2 ± 3.2. The mean age and follow-up were 67 ± 6.8 years and 4.58 ± 1.1 years (range, 2, 12), respectively. The VAS improvement showed at the last follow-up for PCR-BT (range, 1.97, 5.8) and BT (range, 4, 6.1). CMS was improved at the final follow-up for PCR-BT (range, 13, 47.6) and BT (range, 10.8, 28). Regarding the ASES, it has demonstrated significant improvements for PCR-BT (range, 31.81, 44.8) and BT (range, 30,45.8). For forward flexion, PCR-BT showed improvement (range, -14°, 59.4°), as well as the BT group (range, 2°, 27.9°). CONCLUSIONS: This systematic review demonstrated that both BT and PCR-BT improve functional outcomes and reduce pain at midterm follow-up for MIRCT. Since we know that a failed cuff repair would worsen the shoulder, it might be beneficial in terms of the risk-benefit ratio to not repair in certain patients with MIRCT.

Arthroscopic proximal carpal row replacement by semitendinosus and gracilis graft (CArpus Row Plasty Using the Semitendinosus: CARPUS procedure). An anatomical study of 16 cases.

INTRODUCTION: Post-traumatic lesions of the carpus (scapholunate rupture, scaphoid non-union) frequently evolve into disabling osteoarthritis (scapholunate advanced collapse or scaphoid non-union advanced collapse: SLAC or SNAC wrist). Proximal row carpectomy (PRC) is a reliable option but with poorer prognosis in case of osteoarthritis of the distal radius or capitate head. In such situations, radiocarpal arthrodesis may be necessary, sacrificing wrist motion. To circumvent this limitation, we propose a new procedure consisting in arthroscopic PRC and replacing the proximal row by tendon graft. METHODS: This was a study on 16 cadaver specimens. A scapholunate pin was introduced via an approach into the anatomical snuffbox and used as a guide for a cannulated drill bit (9mm) to create a tunnel through the proximal row. The arthroscope and a reamer were introduced into the tunnel via its radial and ulnar ends. PRC was performed under arthroscopic control. The gracilis and semitendinosus tendons were harvested and folded so as to obtain a graft with the same length and diameter as the proximal row. The graft was threaded through the radial approach and fixed to the capsule. RESULTS: Mean procedure time was 68min. There was no pre- to postoperative difference in joint motion or carpal height. On radiocinematography, the graft was stable between the radius and the second row of the carpus. The radial and ulnar sensory branches, median nerve and radial artery were intact at end of procedure. DISCUSSION: This technique could be a solution in SLAC or SNAC wrist with osteoarthritis of the capitate head or radial glenoid. It also conserves carpal height. Being arthroscopic, the procedure avoids the major edema observed after a dorsal approach of the carpus, and also ensures graft stability, since the radiocarpal ligaments are conserved. Harvesting from a second anatomical site and the in vivo fate of the transplant are two issues that need to be discussed. CONCLUSION: This anatomical study paves the way for clinical experimentation. LEVEL OF EVIDENCE: IV.

Use of Gracile and semi-tendinosus tendons (GRAST) for the reconstruction of irreparable rotator cuff tears.

BACKGROUND: Irreparable rotator cuff tears are common and difficult to treat. Techniques for "filling the loss of substance" require fixation to the rotator cuff stump (tendon augmentation) or to the glenoid (superior capsular reconstruction), which are complicated by the narrow working zone of the subacromial space. The main objective of this study was to determine whether a braided graft of gracilis (GR) and semitendinosus (ST) could fill a loss of tendon substance from an irreparable rupture of the supra- and infraspinatus, by fixing the graft to the greater tuberosity and the spine of the scapula. METHODS: This was a cadaveric study with the use of ten specimens. The GRA and ST tendons were harvested, braided and reinforced with suture. An experimental tear of the supraspinatus (SS) and upper infraspinatus (IS) retracted at the glenoid was made. The GRAST transplant was positioned over the tear. The transplant was attached to the greater tuberosity by two anchors and then attached to the medial third of the scapular spine by trans-osseous stitching. The percentage of filling obtained was then measured and passive mobility of the shoulder was assessed. We proceeded to the same technique under arthroscopy for a 73 years old patient whom we treated for a painful shoulder with irreparable cuff tear. We inserted a GRAST graft using arthroscopy. RESULTS: The Braided-GRAST allowed a 100% filling of the loss of tendon substance. Mobility was complete in all cases. CONCLUSION: This technique simplifies the medial fixation and restores the musculo-tendinous chain where current grafting techniques only fill a tendinous defect. The transplant could have a subacromial "spacer" effect and lower the humeral head. The donor site morbidity and the fate of the transplant in-vivo are two limits to be discussed. This anatomical study paves the way for clinical experimentation.

Live Surgery: A retrospective study on the outcomes and complications of 7 orthopedic live surgery events.

INTRODUCTION: Live surgery has always been an invaluable part of medical education. Live Surgery Events (LSE) have recently been criticized in France, arguing that unnecessary risks have been placed on the patients. HYPOTHESIS: We want to report our experience in organizing the last 7 shoulder LSE over the past 12 years focusing on the results and complications during and after the surgeries performed during these courses. MATERIAL AND METHODS: 190 patients benefited from live shoulder surgery between 2005 and 2017. 11 of them were lost to follow up, thus 179 patients were included. The mean follow-up was 7,5 years for the instability group, 6,7 years for the rotator cuff group, 7,5 years for the arthroplasty group and 6,8 years for the nerve group. This study is a retrospective analysis of prospectively collected data. We report the epidemiology of the surgeries perfomed and analyzed the patient outcomes: peri and postoperative complications. We evaluated the educational benefit for the attendees of this shoulder LSE through a questionnaire. RESULTS: There were 6 (3.1%) peri or immediate postoperative complications. There were 33 (18%) long term complications needing 26 (14%) revisions. 90% of the surgeons audience attending the events evaluated the educational benefit from good to very good. DISCUSSION: Over the years, we have standardized the organization of the meeting to ensure maximum safety, while still respecting patient integrity and anonymity. Our complications rates seem within the ranges found in the current literature for each procedure. Our LSE has been an instrument for education, but also for matching patients with complex problems with experienced surgeons, to the benefit of the patient. Our experience has shown that LSE may induce potential dangers and complications can arise. However, these events should follow rigorous rules and not just recommendations. LEVEL OF EVIDENCE: IV; retrospective analysis of prospectively collected data.
