Complex glenoid deformities present the most difficult challenges in shoulder arthroplasty. These deformities may be caused by severe degenerative or congenital deformity, posttraumatic anatomy, tumor, or, in most cases, bone loss after glenoid failure in anatomical total shoulder arthroplasty. Methods of treating severe bone loss have included inlay and onlay bone-graft options with augmented fixation and, in severe cases, salvage hemiarthroplasty with limited goal expectations. Unfortunately, none of these methods has provided consistently satisfactory reproducible results...

BACKGROUND: Anterior shoulder instability has been successfully managed arthroscopically over the past two decades with refined "anatomic" reconstruction procedures involving the use of anchors for the repositioning and re-tensioning of the antero-inferior capsuloligamentous complex, in an effort to recreate its "bumper effect". METHODS: Research and online content related to arthroscopic treatment of shoulder instability was reviewed and their results compared...

BACKGROUND: Generally, a glenoid bone loss greater than 20% to 25% is considered critical for poor surgical outcomes after a soft tissue repair. However, recent studies have suggested that the critical value should be lower. PURPOSE: To determine the critical value of anterior glenoid bone loss that led to surgical failure in patients with anterior shoulder instability. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: The study included 169 patients with anterior glenoid erosion...

PURPOSE: Latarjet, which is a coracoid bone block procedure, is an effective treatment for anterior shoulder instability with glenoid bone loss. During this reconstructive procedure the subscapularis may be tenotomized or be split to expose the glenoid neck. The aim of this study was to assess the effect of subscapularis management on functional outcomes and internal and external rotation durability and strength. Hypothesis is that the subscapularis split approach will result in better functional results and superior internal rotation strength and endurance...

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 desicion-making and clinical outcomes. Although we know that major glenoid bone loss requires surgical intervention, none of the studies performed so far answered the question what size of the defect should be an indication for open surgery procedures...

Bipolar bone loss in patients with anterior glenohumeral instability is challenging to treat. The goal of the treatment is to restore stability by ensuring that the humeral head remains within the glenoid vault. This can be achieved either with the combination of an arthroscopic Bankart procedure and remplissage (glenoid bone loss <25%), or with a Latarjet procedure (glenoid bone loss >25%). In cases with more severe bipolar bone loss of both the glenoid and the humeral head, the conventional approach has been to lengthen the articular arc of the glenoid and to ignore the Hill-Sachs lesion...

Is reverse total shoulder arthroplasty a feasible treatment option for failed shoulder arthroplasty? A retrospective study of 44 cases with special regards to stemless and stemmed primary implants. BACKGROUND: Due to humeral or glenoid bone-loss and rotator cuff insufficiency reverse total shoulder arthroplasty often means the only remaining treatment option in revision shoulder arthroplasty. This study investigates the clinical outcome of patients treated with a reverse total shoulder in revision cases with special regard to stemless and stemmed primary implants...

Significant anteroinferior glenoid bone loss is widely accepted as a major pathology of recurrent anterior shoulder dislocation, particularly after failed arthroscopic Bankart repair. Numerous surgical techniques for glenoid bone grafting have been described and have been reported to yield successful outcomes. Both open and arthroscopic approaches have been used, with the coracoid and the iliac crest being commonly used for bone graft. When compared with open surgery, an arthroscopic approach has many advantages...

Recurrent anterior shoulder instability with significant bone loss represents a surgical challenge. Anterior bone block procedures including variations of the Latarjet coracoid transfer have been used in this setting. Bone graft resorption with prominence of the metalwork is a serious concern, whereas the relative contribution of the dynamic sling effect of a Latarjet procedure is still controversial. We describe an arthroscopic technique for anatomic reconstruction of anterior glenoid bone defects using autologous iliac crest graft...

BACKGROUND: Recognition and proper treatment of glenoid bone loss (GBL) are important for successful management of anterior shoulder instability. Although GBL has been described as the amount of bony loss from the front of the glenoid, there is also a fragment of bone that is usually displaced and often undergoes attrition. Thus, due to attritional bone loss (ABL) of the fragment, insufficient bone is left to fully reconstruct the glenoid. PURPOSE: To (1) evaluate ABL of the glenoid fragment in recurrent anterior shoulder instability and (2) correlate ABL with clinical history, fragment size, and radiographic findings...
