INTRODUCTION This study quantified bone removed to correct three different sizes of posterior glenoid defects and also quantified the change in rotator cuff muscle length resulting from correction of each defect using three different glenoid designs. METHODS A 3-D computer model quantified the cortical and cancellous bone removed when correcting three sizes of posterior glenoid defects and si...

Glenoid and humeral sided bone loss are both independent risk factors for failure after arthroscopic Bankart repair. The purpose of this study was to determine the combined effect subcritical levels glenoid on 171 individuals with minimum 2 years follow up who underwent primary repair between 2007-2015 were included in study. measured using track model. Cases defined as sustained a subluxation ...

Advanced glenohumeral osteoarthritis can transform glenoid morphology and, in some cases, is found in association with severe glenoid retroversion. The associated glenoid retroversion leads to difficulty in fixation of the glenoid component in reverse total shoulder arthroplasty. In the context of extreme glenoid wear, structural grafts can be used to restore glenoid volume and version in order...

Glenoid inclination has been associated with rotator cuff tears and superior humeral translation, but the relationship between glenoid inclination and superior humeral translation has not been assessed in vivo. This study compared glenoid inclination between repaired and contralateral shoulders in 21 unilateral rotator cuff repair patients. As a secondary analysis, we assessed the relationship ...

SUMMARY The universally accepted method of measuring glenoid version to determine proper alignment of the glenoid component during total shoulder arthroplasty does not account for the complex and variable relationship of the glenoid vault with the scapular body. Existing evidence indicates that the glenoid and the scapular body development are controlled by independent genetic and biomechanical...

Bioabsorbable suture anchors are commonly used for arthroscopic repair of rotator cuff and labrum lesions. They provide soft-tissue attachment to bone. They have been introduced to avoid complications such as artefacts on MRI scans, commonly seen with metal anchors. However, bioabsorbable implants may lead to other problems such as local osteolysis, cyst formation, soft tissue inflammation and ...

Computed tomography (CT) immediately after double-contrast shoulder arthrography was taken in twenty-two young male patients with anterior shoulder instability including recurrent dislocation and subluxation. This recently developed technique called CT arthrography can provide significant information about patients with glenohumeral instability which is difficult to obtain by conventional arthr...

BACKGROUND Failed shoulder instability surgery is mostly considered to be the recurrence of shoulder dislocation but subluxation, painful or non-reliable shoulder are also reasons for patient dissatisfaction and should be considered in the notion. METHODS The authors performed a revision of the literature and online contents on evaluation and management of failed shoulder instability surgery....
