Injuries to the glenoid labrum can result in shoulder instability and pain. These lesions may occur anywhere around the glenoid labrum, and thus, the arthroscopist must be prepared to approach all aspects of the glenoid from multiple angles. The pan-labral or circumferential (360°) tear of the glenoid labrum presents a unique challenge to even the experienced arthroscopist. The extent of the le...

During use of the normal shoulder, the humeral head is centered within the glenoid and the coracoacromial arch. When the shoulder cannot maintain this centered position during use, it is unstable. An unstable shoulder prevents normal function of the upper extremity. Shoulder instability is not the same as joint laxity. Joint laxity is a property of normal joints and allows the shoulder to attai...

The glenoid fossa is involved in approximately 10% of all scapular fractures.Glenoid fossa incongruity is surprisingly well tolerated.Surgery is recommended when 20% or more of the anterior glenoid fossa is involved.Glenoid rim fractures often lead to chronic shoulder instability.Unstable glenoid neck fractures need surgical treatment and stable fractures can be treated conservatively.CT examin...

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...

BACKGROUND Posterior glenoid bone deficiency in the setting of posterior glenohumeral instability is typically addressed with bone block augmentation with iliac crest bone grafts (ICBGs). Reconstruction with fresh distal tibial allograft (DTA) is an alternative option, with the theoretical advantages of restoring the glenoid articular surface, improving joint congruity, and providing the biolog...
