BACKGROUND Recurrent shoulder instability is commonly associated with glenoid bone defects. Coracoid transfer procedures, such as the Bristow and Latarjet procedures, are frequently used to address these bone deficiencies. Despite the frequent synonymous labeling of these transfers as the "Bristow-Latarjet" procedure, their true equivalence has not been demonstrated. Therefore, our purpose was ...

BACKGROUND Representing 3%-5% of shoulder girdle injuries scapula fractures are rare. Furthermore, approximately 1% of scapula fractures are intraarticularfractures of the glenoid fossa. Because of uncertain fracture morphology and limited experience, the treatment of glenoid fossa fractures is difficult. The glenoid fracture classification by Ideberg (1984) and Euler (1996) is still commonly u...

BACKGROUND Posttraumatic anterior shoulder instability is associated with anterior glenoid bone loss, contributing to recurrence. Accurate preoperative quantification of bone loss is paramount to avoid failure of a soft tissue stabilization procedure as bone reconstruction is recommended for glenoid defects greater than 20% to 27%. QUESTIONS/PURPOSES We determined whether radiography, MRI, or...

Objectives: Limited studies have compared graft-glenoid apposition and glenoid augmentation area between the latarjet distal clavicle grafts in glenohumeral stabilization. Additionally, pre-operative planning is typically performed using computerized tomography (CT), few used 3- dimensional magnetic resonance imaging (3D-MRI) reformations to assess graft dimensions. The purpose of study was two...

BACKGROUND The purpose of this study was to evaluate the angle between the long head of the biceps tendon (LHBT) and the glenoid during arthroscopic surgery and its correlation with biceps subluxation on magnetic resonance imaging (MRI). Furthermore, we evaluated the relationship of this angle with subscapularis tears and biceps pathologies. METHODS MRI and arthroscopic images of 270 consecut...

HYPOTHESIS Anterior instability is one of the most common complications in reverse shoulder replacement. This study hypothesized that intrinsic stability of a reverse prosthesis varies with the degree of version of the humerus and glenoid components. This should provide guidelines on how to best position the implant components to decrease the rate of dislocation. MATERIALS AND METHODS Resista...

We performed a prospective study using MRI in 16 consecutive infants with a mean age of 5.2 months (2.7 to 8.7) who had shown inadequate recovery from an obstetric lesion of the brachial plexus in the first three months of life, in order to identify early secondary deformities of the shoulder. Shoulders were analysed according to a standardised MRI protocol. Measurements were made of the appear...

We conducted a retrospective study of 36 patients with reverse shoulder prostheses to assess whether placement of the glenoid component affected development of scapular notches. Minimum follow-up was 2 years. Glenosphere position and its relation to scapular notching was analyzed radiographically. The glenosphere overhung the inferior glenoid rim in 19 cases (52.8%) and was flush with the rim i...
