Anterior glenoid rim fracture is a consequence of the humeral head impacting the glenoid fossa. The management of large glenoid fractures involving more than 20% of the articulating glenoid requires surgical treatment. The 2 main techniques are open reduction internal fixation (ORIF) by screws and arthroscopic treatment using suture anchors or transcutaneous screws. Next to the technical equipment, a surgeon requires extensive experience to achieve good results with the arthroscopic technique. The main disadvantage using the ORIF technique is the detachment of the subscapularis muscle, which is often criticized for causing functional deficits of the subscapularis. Our study demonstrates the feasibility of the ORIF technique through a deltopectoral approach and splitting of the subscapularis. To our knowledge, subscapularis splitting has never been described to treat glenoid fractures.

Biomechanical Outcomes of Glenoid Bone Graft Fixation Techniques: A Systematic Review.
Am J Sports Med

Mayo Clinic Arizona Department of Orthopedic Surgery, Phoenix, Arizona, USA.
Background: The Latarjet and other bony augmentation procedures are commonly used to treat anterior shoulder instability in the setting of significant glenoid bone loss. Although several fixation strategies have been reported, the biomechanical strength of these techniques remains poorly understood.
Purpose: To perform a systematic review of the biomechanical strength of glenoid bony augmentation procedures for anterior shoulder instability.

Background: While risk factors for recurrent instability (RI) after arthroscopic Bankart repair (ABR) for anterior glenohumeral instability (aGHI) have been well established in adult populations, there is much less evidence in pediatric and adolescent patients, despite being the most affected epidemiologic subpopulation.
Purpose: To identify the clinical, demographic, radiologic, and operative risk factors for RI after ABR for aGHI in pediatric and adolescent patients.
Study Design: Systematic review; Level of evidence, 4.
The Radiologic Evaluation and Clinical Significance of Glenohumeral Bone Loss in Anterior Shoulder Instability.

Glenoid and humeral bone loss is associated with a high incidence of recurrent shoulder instability and failure of arthroscopic stabilization procedures. However, the radiographic evaluation of bony Bankart and Hill-Sachs injuries continues to pose a diagnostic challenge, and a universally accepted optimal method of measurement is lacking. The purpose of this review is to summarize the advantages and disadvantages of various techniques and imaging modalities available for measuring glenoid bone loss in shoulder instability, including conventional roentgenography, 2-dimensional and 3-dimensional computed tomography (CT), and magnetic resonance imaging (MRI).

This study develops deep learning (DL) models to detect Bankart lesions on both standard MRIs and MRAs, aiming to improve diagnostic accuracy and reduce reliance on MRAs. We curated a dataset of 586 shoulder MRIs (335 standard, 251 MRAs) from 558 patients who underwent arthroscopy.

Electronic address:
Background: Arthroscopic repair is recommended for patients with bony Bankart lesions to restore anterior shoulder stability and avoid recurrent glenohumeral instability. The aim of this study was to investigate the clinical and radiological outcomes of patients following arthroscopic bony Bankart repair using a single suture anchor fixation technique named the "door-locking" technique.
Methods: From January 2017 to February 2024, a consecutive series of 22 patients with acute bony Bankart lesions underwent shoulder arthroscopy.
