[PMID: 38506977 DOI: 10.1007/s00276-024-03337-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 02/27/2024] [Indexed: 03/22/2024]
Abstract
PURPOSE The open Trillat Procedure described to treat recurrent shoulder instability, has a renewed interest with the advent of arthroscopy. The suprascapular nerve (SSN) is theoretically at risk during the drilling of the scapula near the spinoglenoid notch. The purpose of this study was to assess the relationship between the screw securing the coracoid transfer and the SSN during open Trillat Procedure and define a safe zone for the SSN. METHODS In this anatomical study, an open Trillat Procedure was performed on ten shoulders specimens. The coracoid was fixed by a screw after partial osteotomy and antero-posterior drilling of the scapular neck. The SSN was dissected with identification of the screw. We measured the distances SSN-screw (distance 1) and SSN-glenoid rim (distance 2). In axial plane, we measured the angles between the glenoid plane and the screw (α angle) and between the glenoid plane and the SSN (β angle). RESULTS The mean distance SSN-screw was 8.8 mm +/-5.4 (0-15). Mean α angle was 11°+/-2.4 (8-15). Mean β angle was 22°+/-6.7 (12-30). No macroscopic lesion of the SSN was recorded but in 20% (2 cases), the screw was in contact with the nerve. In both cases, the β angle was measured at 12°. CONCLUSION During the open Trillat Procedure, the SSN can be injured due to its anatomical location. Placement of the screw should be within 10° of the glenoid plane to minimize the risk of SSN injury and could require the use of a specific guide or arthroscopic-assisted surgery.

Abstract
The Trillat procedure has been described for the management of shoulder instability in younger patients but also for shoulder instability in older patients with irreparable rotator cuff tears. We describe an all-arthroscopic technique using screw fixation. This technique allows for safe dissection, clearance and osteotomy of the coracoid, and direct visualization during screw tensioning and fixation to minimize the risk of subscapularis impingement. We outline our stepwise approach to medialize and distalize the coracoid process using arthroscopic screw fixation and present pearls to avoid fracture through the superior bone bridge.

Abstract
Hyperlaxity is a common factor in failed arthroscopic Bankart repair. The best treatment for patients with instability, hyperlaxity, and minimal bone loss is still controversial. Patients with hyperlaxity often have subluxations rather than frank dislocation, and concurrent traumatic structural lesions are infrequent. Conventional arthroscopic Bankart repair with or without capsular shift poses a risk of recurrence because of soft tissue insufficiency. The Latarjet is not a good procedure in patients with hyperlaxity and instability, especially an inferior component, and risks include a higher degree of postoperative osteolysis after Latarjet with an intact glenoid. The arthroscopic Trillat procedure may be used to treat this challenging patient group by repositioning the coracoid medially and downward by a partial wedge osteotomy. The coracohumeral distance and shoulder arch angle are decreased after performing the Trillat, which may reduce instability, and the Trillat procedure mimics the sling effect of the Latarjet. However, complications should be considered due to the procedure's nonanatomic nature, such as osteoarthritis, subcoracoid impingement, and loss of motion. Other options to improve inferior stability include robust rotator interval closure, coracohumeral ligament reconstruction, and posteroinferior/inferior/anteroinferior capsular shift. The addition of posteroinferior capsular shift and rotator interval closure in the medial lateral direction also benefits this vulnerable patient group.

Abstract
PURPOSE OF REVIEW Shoulder instability in patients with underlying joint hyperlaxity can be challenging to treat. Poorly defined terminology, heterogeneous treatments, and sparse reports on clinical outcomes impair the development of best practices in this patient population. This article provides a review of the current literature regarding optimal management of patients suffering from shoulder instability with concomitant hyperlaxity of the shoulder, from isolated shoulder joint hyperlaxity to congenital hypermobility spectrum disorders (HSD). RECENT FINDINGS Current research shows specialized physiotherapy protocols focused on strengthening of periscapular muscles and improvement of sensorimotor control are a promising non-surgical therapeutic avenue in certain patients, which can be augmented by device-based intervention in select cases. If surgical treatment is warranted, arthroscopic techniques such as pancapsular shift or plication continue to demonstrate favorable outcomes and are currently considered the benchmark for success. The long-term success of more recent innovations such as coracoid process transfers, conjoint tendon transfers, subscapularis tendon augmentation, and capsular reconstruction remains unproven. For patients affected by connective tissue disorders, treatment success is generally less predictable, and the entire array of non-operative and operative interventions needs to be considered to achieve the best patient-specific treatment results. In the treatment of shoulder instability and concomitant hyperlaxity, specialized physiotherapy protocols augmented by device-based interventions have emerged as powerful, non-operative treatment options for select patients. Successful surgical approaches have been demonstrated to comprehensively address capsular redundancy, labral lesions, and incompetence of additional passive stabilizers in a patient-specific fashion, respective of the underlying connective tissue constitution.

High resorption rates following glenoid augmentation procedures do not seem to lead to higher recurrence rates or worse clinical outcomes: a systematic review and meta-analysis. Knee Surg Sports Traumatol Arthrosc 2022:10.1007/s00167-022-07267-x.

Abstract
PURPOSE Bone augmentation techniques show a relatively high complication rate, which might be due to graft non-union and resorption. It is unclear which augmentation techniques demonstrate the highest amount of non-union and resorption and whether this leads to worse clinical or functional outcomes. Therefore, the aim of this review was (i) to compare non-union and resorption rates between surgical approaches, procedures, graft types, donor sites and fixation methods regarding clinical and functional outcomes and (ii) determine whether high non-union or resorption rates lead to less favorable clinical or functional outcomes. METHODS The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statements were followed. PubMed, EMBASE (Ovid) and Cochrane Library were searched on December 15th 2021 for studies examining bone graft non-union or resorption using radiograph or CT following glenoid augmentation to treat anterior shoulder dislocation. RESULTS The search resulted in 103 inclusions, comprising 5,128 glenoid augmentations. When comparing pooled proportions of bony union, graft fracture rate, hardware failure rate, recurrence rate, return to sports and Rowe score, most results were similar between approaches, procedures, graft types, donor sites and fixation methods. High resorption rates were seen for allograft augmentation (74.3; 95% CI: 39.8-92.7) compared to autograft augmentation (15.5; 95% CI 10.1-23.2), but this was not associated with higher recurrence rates or worse clinical outcomes. Meta-analyses (8 studies; 494 patients) demonstrated no difference in incomplete and complete non-union rates between arthroscopic and open procedures; however, both analyses showed substantial heterogeneity. Higher partial resorption rates were observed on CT (48.0; 95% CI 43.3-52.7) compared to radiograph (14.1; 95% CI 10.9-18.1). Three studies comprising 267 shoulders demonstrated a higher rate of non-union and recurrence in smokers, whereas one study comprising 38 shoulders did not. CONCLUSION Non-union and resorption rates were similar among procedures, grafts and fixation methods. Higher resorption rates were observed in allografts, but this was not associated with higher recurrence rates or worse clinical outcomes. Pooling data demonstrated substantial heterogeneity and definitions varied among studies, warranting more standardized measuring. LEVEL OF EVIDENCE IV.

Abstract
» Anterior glenohumeral instability (AGI) is a challenging condition that requires close attention to osseous and soft-tissue abnormalities. The morphometric variance of the periarticular scapular anatomy may be involved in the pathogenesis of recurrent traumatic anterior instability. » The Trillat procedure repositions the coracoid medially and downward by a partial wedge osteotomy, mimicking the sling effect of the Latarjet procedure by moving the conjoint tendon closer to the joint line in throwing position. The Trillat procedure decreases the coracohumeral distance without affecting the integrity of the subscapularis muscle and tendon. » Joint preservation methods, such as the Trillat procedure, may be explored in older patients to treat AGI with simultaneous irreparable rotator cuff tears (RCTs) with a static centered head and a functional subscapularis. » Shoulder hyperlaxity and instability can be challenging to treat with isolated soft-tissue procedures. In cases without glenoid bone loss, free bone block techniques are ineffective because of the subsequent potential graft resorption, apprehension, or recurrence. The Trillat surgery, in conjunction with an anteroinferior capsuloplasty, seems to be helpful in preventing recurrent instability and in reducing shoulder apprehension. » Recently, several variations of the original technique have been described. In the future, anatomical, biomechanical, and clinical studies need to be conducted to further evaluate the morphometric characterization of the procedure, enhance the technical features, improve indications, and avoid coracoid impingement and other potential complications with the Trillat procedure.
