The Evaluation and Management of the Failed Primary Arthroscopic Bankart Repair

Recurrent Instability after the Latarjet Procedure

The Latarjet procedure is a favored approach for managing chronic and recurrent dislocation, especially in the presence of bone loss. Although generally yielding excellent results, the procedure carries a 15 to 30% complication rate. Although recurrent instability is a major concern, various complications such as infection, nerve injuries, and hardware impingement can also necessitate revision after a Latarjet procedure. Strategies for addressing this issue include glenoid bone grafting, using autogenous bone grafts from the iliac crest or distal clavicle, and allografts, with fresh lateral distal tibial allografts offering advantages because of their osteochondral nature. In addition, soft-tissue procedures offer another solution for recurrent instability, suitable for patients lacking substantial bone loss or those experiencing multidirectional instability. This review aims to provide a comprehensive overview of the causes and management strategies for recurrent instability following a failed Latarjet procedure.

Managing Bone Loss in Shoulder Instability-Techniques and Outcomes: a Scoping Review

PURPOSE OF REVIEW

The aim of this scoping review is to provide an overview of the literature published over the past 5 years related to the management of bone loss in anterior shoulder instability.

RECENT FINDINGS

During recent years, there has been a focus on patients at high risk for failure following soft tissue anterior stabilization (Bankart repair). A growing body of evidence suggests that anterior capsulolabral repair is insufficient in the setting of subcritical glenoid bone loss with an off-track Hill Sachs lesion. In such cases, the addition of a remplissage procedure to a Bankart repair or a bone-block augmentation to the glenoid (Latarjet, for example) is often advocated to decrease the risk of recurrent instability. Recent studies have also evaluated the role of alternative bone-block procedures in comparison to the Latarjet, outcomes with arthroscopic and open techniques as well as various fixation methods and radiological outcomes (bone graft resorption, glenohumeral osteoarthritis). Advances in our understanding of subcritical glenoid bone loss and the glenoid track concept have significantly impacted clinical decision making and treatment selection. The development of arthroscopic techniques has allowed for minimally invasive and safe arthroscopic bone-block procedures as an alternative to open procedures. Further research related to free bone-block procedures will inform long-term outcomes between these procedures and the gold standard Latarjet. Additionally, high-quality evidence is lacking to identify the ideal treatment for patients with glenoid subcritical glenoid bone defect. Variability in outcome reporting suggests the need to standardize outcome measures for future instability trials.

Arthroscopic Repair of Humeral Avulsion of the Glenohumeral Ligament for Anterior Shoulder Instability

Humeral avulsion of the glenohumeral ligament (HAGL) is a rare cause of anterior shoulder instability. Recurrent instability and anterior shoulder pain could be caused by an unrepaired HAGL; therefore, making the diagnosis is crucial. Only a few articles describe arthroscopic HAGL repair. This uncommon technique uses lateral decubitus arthroscopy and standard Bankart instrumentation. Different methods used to facilitate visualization of the working space as well as anchor placements are described.
