BACKGROUND Several risk factors for the postoperative recurrence of instability after arthroscopic Bankart repair have been reported, but there have been few detailed investigations of the specific risk factors in relation to the type of sport. PURPOSE This study investigated the postoperative recurrence of instability after arthroscopic Bankart repair without additional reinforcement procedu...

INTRODUCTION: The Latarjet procedure is commonly used to treat glenoid bone loss due to recurrent instability and dislocation. In this procedure, the coracoid process is osteotomized from its native position and fixed to the anterior glenoid at the site of bone loss. As a result, the coracoid acts as an extension of the glenoid face, thus restoring the glenoid articulating surface and increasin...

This article describes the case of a 77-year-old man with a recurrent posterior shoulder dislocation, treated with humeral hemiarthroplasty and reconstruction of a large posteroinferior glenoid defect with a bone block created from humeral head autograft. On examination, the patient's left arm was held in internal rotation against his stomach, with minimal swelling about the deltoid. His should...

BACKGROUND Current glenoid defect measurement techniques only quantify bone loss in terms of defect diameter or surface. However, the glenoid depth plays an important role in shoulder stabilization by means of concavity compression. CASE PRESENTATION We present a case of a professional wrestler who suffered from anterior shoulder instability after sustaining a bony Bankart lesion without loss...

Shoulder stability depends on the position of the arm as well as activities of the muscles around the shoulder. The capsulo-ligamentous structures are the main stabilisers with the arm at the end-range of movement, whereas negative intra-articular pressure and concavity-compression effect are the main stabilisers with the arm in the mid-range of movement.There are two types of glenoid bone loss...

BACKGROUND The present study investigated individualized coracoid osteotomy for 3D congruent arc glenoid reconstruction and evaluated the clinical outcomes in recurrent anterior shoulder dislocation. METHODS From January 2005 to July 2015, 78 patients with glenoid defect underwent coracoid and conjoint tendon transposition. The patients were divided into the individualized group (n = 34) and ...

Recurrent anterior shoulder instability may result from a spectrum of overlapping, often coexistent factors, one of which is glenoid bone loss. Untreated, glenoid bone loss may lead to recurrent instability and poor patient satisfaction. Recent studies suggest that the glenoid rim is altered in up to 90% of shoulders with recurrent instability, thus underscoring the need for careful diagnosis, ...

BACKGROUND Shoulders with recurrent anterior instability often have combined bony defects of the humeral head and glenoid. Previous studies have looked at only isolated humeral head or glenoid defects. PURPOSE/HYPOTHESIS The aim of this study was to define the relationship of combined humeral head and glenoid defects on anterior shoulder instability. Combined bony defects will lead to increas...

BACKGROUND Large glenoid rim defects in patients with traumatic anterior shoulder instability are often regarded as a contraindication for arthroscopic Bankart repair, with a defect of 20% to 27% considered as the critical size. While recurrence of dislocations, male sex, and collision sports were reported to be the significant factors influencing large glenoid defects, the influences of sublux...
