INTRODUCTION: The stability of the glenohumeral joint (GHJ) is dependent upon passive stabilizing mechanisms such as the glenoid labrum and long head of the biceps (LHB) tendon. The labrum improves GHJ stability by increasing the glenoid concavity, and the contiguous structure of the labrum and LHB tendon may increase tension on the labrum during superior humeral translations which may contribu...

An osseous Bankart lesion is commonly seen in patients with an anterior shoulder dislocation. It is defined as a detachment of the anteroinferior labrum associated with a glenoid rim fracture. Radiological studies are crucial not only for detecting glenoid bone defects but also for measuring the amount of bone loss. The precise quantification of the bony defect is crucial for the therapeutic de...

The goal of this study was to compare the accuracy of abduction-external rotation magnetic resonance arthrography (ABERMRA) with standard MRA in the diagnosis of intra-articular shoulder pathology.One hundred three consecutive patients undergoing preoperative direct MRA and subsequent arthroscopic examination were included in the study. Seventy-eight patients underwent standard MRA and 25 under...

The high recurrence rate associated with anterior shoulder dislocations may reflect inadequate healing of a Bankart lesion when the arm is immobilized in internal rotation. The effect of external rotation (ER) of the humerus on the glenoid-labrum contact of Bankart lesions was examined in 10 human cadaveric shoulders. The contact force between the glenoid labrum and the glenoid was measured in ...

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...

BACKGROUND Resorbable anchors are widely used in arthroscopic stabilization of the shoulder as a means of soft tissue fixation to bone. Their function is to ensure repair stability until they are replaced by host tissue. Complications include inflammatory soft tissue reactions, cyst formation, screw fragmentation in the joint, osteolytic reactions, and enhanced glenoid rim susceptibility to fra...

Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. Only 13 cases around the shoulder have been described in the literature. These lesions are often asymptomatic, but, in cases located close to neurovascular structures or articular surfaces, they can be symptomatic, causing pain, neurologic dysfunction, or articular fractures. This article re...

Arthroscopic stabilization has proven an effective technique in the treatment of anterior shoulder instability due to soft tissue labrum/ligamentous (i.e. Bankart) injury. However, this procedure has not proven as reliable in patients with glenoid rim fractures that have either been neglected or unrecognized, and gone on to resorb. Consequently, there has been a growing emphasis on the importan...

BACKGROUND It is not clear whether the anterior capsule should be repaired to the coracoid process or to the native glenoid during the modified Latarjet procedure. We investigated joint stability and range of motion of the shoulder after the modified Latarjet procedure with both of these methods of capsular repair. METHODS Eighteen fresh-frozen cadaveric shoulders were used. After a Bankart l...
