Background Bone defects of the glenoid are often found in patients with traumatic anterior glenohumeral instability. There is no consensus regarding which glenoid defects need to be treated surgically. The aim of this review is to describe the management of glenoid defects in anterior shoulder instability in patients with traumatic anterior glenohumeral instability. Methods We conducted a rev...

Osteochondral disease of the glenoid is a well-known cause of shoulder pain and disability in young and active patients. The etiology can be multifactorial, and disease severity can exist across a wide spectrum. Symptoms can often interfere with athletic performance, job responsibilities, and activities of daily living. Although a number of cartilage restoration techniques exist for other joint...

The three-dimensional (3D) correction of glenoid erosion is critical to the long-term success of total shoulder replacement (TSR). In order to characterise the 3D morphology of eroded glenoid surfaces, we looked for a set of morphological parameters useful for TSR planning. We defined a scapular coordinates system based on non-eroded bony landmarks. The maximum glenoid version was measured and ...

Secure and lasting fixation of the glenoid component in total shoulder arthroplasty is difficult because there is an insufficient volume of strong bone in the scapula. Consequently, radiolucencies of the glenoid component are common (much more common than radiolucencies of the humeral component). Early glenoid component designs were fabricated wholly from polyethylene, were fixated with PMMA ce...

A new arthroscopic approach for traumatic instability has been developed with which avulsed capsulolabral tissue can be effectively attached to the glenoid articular rim with sutures, providing anatomic reattachment and effective deepening of the glenoid concavity similar to that achieved by open repair. This technique does not depend on fixation devices, trans-scapular drilling, or implantatio...

BACKGROUND One possible cause of shoulder pain is rotator cuff contact with the superior glenoid (cuff-glenoid contact) with the arm in flexion, as occurs during a Neer impingement sign. It has been assumed that the pain with a Neer impingement sign on physical examination of the shoulder was secondary to the rotator cuff making contact with the anterior and lateral acromion. QUESTIONS/PURPOS...

Surgical treatment for traumatic, anterior glenohumeral instability requires repair of the anterior band of the inferior glenohumeral ligament, usually at the site of glenoid insertion, often combined with capsuloligamentous plication. In this study, we determined the mechanical properties of this ligament and the precise anatomy of its insertion into the glenoid in fresh-frozen glenohumeral jo...

Shoulder arthroplasty represents one of the fastest growing orthopaedic procedures in the USA. In comparison to hemiarthroplasty, total shoulder arthroplasty has higher patient satisfaction and lower revision rates. Aseptic glenoid loosening remains a concern for longevity of total shoulder arthroplasties. Cement fixation on the glenoid side represents the primary and only mode of fixation in t...

Achieving sufficient exposure of the glenoid is one of the most demanding aspects of shoulder arthroplasty surgery. Beginning with the positioning of patient and ending with the final placement and adjustment of retractors, multiple maneuvers must be taken at each step of the procedure to ultimately allow for adequate glenoid visualization. With thoughtful planning, patience, and attention to d...

Newer glenoid components that allow for hybrid cement fixation via traditional cementation of peripheral pegs and bony ingrowth into an interference-fit central peg introduce the possibility of long-term biological fixation. However, little biomechanical work has been done on the initial stability of these components and the various fixation options. We conducted a study in which all-polyethyle...
