Background: Our aim is to determine the interobserver reliability for surgeons to detect Hill-Sachs lesions on magnetic resonance imaging (MRI), the certainty of judgement, and the effects of surgeon characteristics on agreement.
Methods: Twenty-nine patients with Hill-Sachs lesions or other lesions with a similar appearance on MRIs were presented to 20 surgeons without any patient characteristics. The surgeons answered questions on the presence of Hill-Sachs lesions and the certainty of diagnosis. Interobserver agreement was assessed using the Fleiss' kappa (κ) and percentage of agreement. Agreement between surgeons was compared using a technique similar to the pairwise t-test for means, based on large-sample linear approximation of Fleiss' kappa, with Bonferroni correction.
Results: The agreement between surgeons in detecting Hill-Sachs lesions on MRI was fair (69% agreement; κ, 0.304; p<0.001). In 84% of the cases, surgeons were certain or highly certain about the presence of a Hill-Sachs lesion.
Conclusions: Although surgeons reported high levels of certainty for their ability to detect Hill-Sachs lesions, there was only a fair amount of agreement between surgeons in detecting Hill-Sachs lesions on MRI. This indicates that clear criteria for defining Hill-Sachs lesions are lacking, which hampers accurate diagnosis and can compromise treatment.

Purpose: To compare functional outcomes, recurrence rate, range of motion (ROM) and return to sport between arthroscopic Bankart repair with remplissage (BR) and open Bankart repair with inferior capsular shift (OBICS) in contact and collision athletes with recurrent anterior shoulder instability.
Methods: A prospective comparative cohort study of 90 patients separated into two study groups (OBICS and BR) of 45 collision and contact athletes each was conducted. All athletes had subcritical glenoid bone loss (SGBL) ≤ 10% and off-track Hill Sach lesions (HSLs).
Glenoid bone loss and patient history influence surgical decision-making for bony Bankart lesion: A mid-term follow-up retrospective study.
J Shoulder Elbow Surg

Concordia Hospital, Rome, Italy.
Background: To analyze how patient history, glenoid bone loss (GBL), and the size of the residual glenoid bone fragment (GBF) influence the choice between arthroscopic Bankart repair and open Latarjet procedure in patients with anteroinferior glenohumeral instability and bony Bankart lesions.
Methods: Review of 290 patients with bony Bankart lesions treated for anterior glenohumeral instability was conducted and patients were categorized into three groups based on GBL and GBF: Group A (GBL < 10% and GBF <10%), Group B (GBL ≥ 10% and GBF <10%), and Group C (GBL ≥10%, GBF ≥10%). Number of preoperative dislocations, time from the first instability, Western Ontario Shoulder Index (WOSI) scores, Hill-Sachs lesion (HSL) location (central or peripheral), HSL track status, and Glenoid Track Instability Management Score (GTIMS) were analyzed.
Comparison of Revision and Redislocation Rates After First-Time Anterior Shoulder Instability Between Subluxators and Dislocators: A Midterm Outcome Study.
Orthop J Sports Med
December 2024
Department of Orthopaedic Surgery, UPMC Freddie Fu Sports Medicine Center, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA.
Background: Anterior shoulder instability is a common pathology seen especially in young men and highly active patient populations. Subluxation is a commonly encountered clinical issue, yet little is known about the effects of first-time subluxation compared with dislocation on shoulder stability and clinical outcomes after surgical stabilization.
Purpose: To compare revision and redislocation rates as well as patient-reported outcomes (PROs) between subluxators and dislocators after a first-time anterior shoulder instability event.
Characteristics of High-Risk Bipolar Bone Loss Lesions Using 3-Dimensional Imaging.

Steadman Philippon Research Institute, Vail, Colorado, USA.
Background: The concept of on-track versus off-track bone lesions in glenohumeral instability continues to evolve. Although much has been ascertained from an original biomechanical model, bony pathological changes, especially on 3-dimensional (3D) imaging, have not been fully evaluated.
Purpose: To compare the differences in on-track versus off-track lesions to characterize glenoid and humeral head bone defects using 3D modeling software.

Introduction: Posterior shoulder dislocation with a reverse Hill-Sachs lesion is a rare and complex injury, requiring specialized treatment due to the difficulty in diagnosis, reduction, and addressing both sides of the pathology to reduce the potential for recurrent dislocation.
Purpose: To evaluate the clinical and functional outcomes of closed reduction and arthroscopic McLaughlin procedure with posterior labral repair in patients with neglected locked posterior shoulder dislocation for less than 12 weeks.
Methods: A prospective study was conducted at university hospitals, managing 15 patients with neglected locked posterior shoulder dislocation for less than 12 weeks and concomitant engaging reverse Hill-Sachs lesions of less than 40% of the humeral articular surface.
