Anterior glenoid bone loss is present in nearly all cases of recurrent anterior glenohumeral instability. Treating glenoid bone loss in the setting of recurrent instability is challenging, and often, soft tissue stabilization procedures in isolation are inadequate. The nonanatomic, incongruous joint resulting from most bony augmentation procedures has motivated investigators to find an alternat...

BACKGROUND Aseptic loosening of glenoid components is a common problem associated with total shoulder arthroplasty and one cause for failure. A new cementless fluted glenoid component was developed and has shown excellent bony ingrowth in a canine model. HYPOTHESIS Clinical utilization of this cementless fluted pegged glenoid component in total shoulder arthroplasty would lower rates of radio...

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...

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...

Anatomic factors, such as a hooked acromion, have been associated with rotator cuff disorders. Orientation of the glenoid relative to the scapula has been implicated in shoulder instability, but it has not been linked to rotator cuff disorders. The purpose of the current study was to test the hypothesis that superior inclination of the glenoid is associated with full-thickness rotator cuff tear...

Introduction Recurrent instability of the glenohumeral joint is usually associated with a Bankart tear—a soft-tissue injury of the glenoid labrum attachment. However, patients with recurrent shoulder instability often present with osseous injury to the glenoid and humeral head as well. Understanding and appropriately addressing irregularities in the osseous architecture of the glenohumeral join...

We performed ninety-five consecutive Latarjet procedures for the treatment of recurrent anterior instability of the shoulder between 1969 and 1983. In 1993, we retrospectively reviewed the clinical and radiographic results that were available for fifty-six patients (fifty-eight shoulders) who had been followed for an average of 143 years (range, ten to twenty-three years). The purpose of the st...

INTRODUCTION The concept of the study was to compare the morphometry of the suprascapular notch (SSN) in females and males because its size and shape may be a factor in suprascapular nerve entrapment. MATERIAL AND METHODS The measurements of 81 scapulae included morphological length and width, maximal width and length projection of the scapular spine, and width and length of the glenoid cavit...
