BACKGROUND: Glenoid bone defect and excessive medialization could represent challenging issues during reverse shoulder arthroplasty, especially in the setting of revision surgery. Although a solution is offered by the Boileau's BIO-RSA technique in primary cases, only autologous iliac crest bone graft and homologous graft from bone banks are available for revision surgeries, with known disadvantages and risk of graft resorption and implant failure. MATERIALS AND METHODS: We describe in this work a new technique based on a customized porous tantalum device to be used in salvage situations, aimed at lateralization of the glenoid component of a reverse shoulder arthroplasty...

Humeral bone loss has been shown to be a risk factor for failure after arthroscopic treatment of instability. We present the arthroscopic remplissage technique originally described by Koo and Burkhart et al. with a modification in the percutaneous anchor placement and suture tying that is reproducible and effective. We percutaneously place 2 suture anchors, which require no additional suture passing across the tissue, to create a double pulley technique, filling the defect with posterior capsule and rotator cuff...

BACKGROUND: Chronic osteoarthritis can result in glenohumeral subluxation and loss of posterior glenoid bone. This can alter normal glenohumeral biomechanics and affect the stress placed on the glenoid implant after total shoulder arthroplasty. This study evaluated the clinical and radiographic results of an augmented all-polyethylene glenoid for the treatment of glenoid osteoarthritis in the presence of posterior glenoid bone loss and determined whether any failures or complications occurred with short-term follow-up...

BACKGROUND: Glenoid and humeral bone loss are well-described risk factors for failure of arthroscopic shoulder stabilization. Recently, consideration of the interactions of these types of bone loss (bipolar bone loss) has been used to determine if a lesion is "on-track" or "off-track." The purpose of this study was to study the relationship of the glenoid track to the outcomes of arthroscopic Bankart reconstructions. METHODS: Over a 2-year period, 57 shoulders that were treated with an isolated, primary arthroscopic Bankart reconstruction performed at a single facility were included in this study...

BACKGROUND: Treating shoulders with osteoarthritis, an intact rotator cuff, and substantial glenoid bone loss is challenging. One option is reaming the glenoid flat and inserting a reverse prosthesis. This study reports the subjective, objective, and radiographic results of reverse total shoulder arthroplasty (RTSA) in this population. METHODS: We retrospectively reviewed 42 consecutive patients (23 women; mean age, 71 years [range, 53 to 89 years]) with primary glenohumeral osteoarthritis, intact rotator cuffs, and Walch type-A2 (n = 19), B2 (n = 5), or C glenoids (n = 18) who had undergone a total of 42 RTSAs with glenoid reaming without bone-grafting between 2008 and 2013 (mean follow-up, 36 months [range, 24 to 66 months])...

Shoulder dislocations are a common injury, with anterior shoulder dislocation among male patients being the most common presentation. A patient with recurrent shoulder instability, anterior-superior escape, and chronic subscapularis tendon rupture following multiple shoulder stabilization surgeries presents the surgeon with a complex and challenging case. This report describes a 40-year-old man with an extensive left shoulder history that included a failed Latarjet procedure, an irreparable, chronic subscapularis tear with grade 4 Goutallier fatty infiltration, and associated anterior-superior escape...

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 alternative solution. Recently, the use of fresh distal tibia allograft has been reported as an anatomic, osteoarticular reconstructive option for restoring the glenoid arc and maintaining glenohumeral congruency...

The preoperative assessment of anterior glenoid bone loss is a critical step in surgical planning for patients with recurrent anterior glenohumeral instability. The structural integrity of the glenoid has been identified as one of the most important factors influencing the success of operative repair. The currently accepted gold standard for glenoid structural assessment among most orthopaedic surgeons is the use of 3-dimensional reconstructed computed tomography images with the humeral head digitally subtracted, yielding an en face sagittal oblique view of the glenoid...

Failed arthroscopic soft-tissue stabilization and anterior glenoid bone loss have been shown to have high failure rates after standard arthroscopic stabilization techniques. For patients with recurrent glenohumeral instability, the Bristow-Latarjet procedure is currently the standard of care. It is predominantly performed through an open deltopectoral approach but has recently been described arthroscopically. Although providing excellent clinical outcomes, the Bristow-Latarjet procedure violates the subscapularis muscle, has a steep learning curve with a high complication rate, and permanently changes the anterior shoulder anatomy, making any future revision surgery more challenging...

CONTEXT: Posterior shoulder instability has become more frequently recognized and treated as a unique subset of shoulder instability, especially in the military. Posterior shoulder pathology may be more difficult to accurately diagnose than its anterior counterpart, and commonly, patients present with complaints of pain rather than instability. "Posterior instability" may encompass both dislocation and subluxation, and the most common presentation is recurrent posterior subluxation. Arthroscopic and open treatment techniques have improved as understanding of posterior shoulder instability has evolved...

PURPOSE: Estimation of anterior glenoid bone loss is important for surgical decision-making. The purpose of this study was to describe a method for estimating anterior glenoid bone loss. METHODS: Thirty-nine cadaveric glenoids were digitized to obtain glenoid geometry. Glenoid bare spot centre, arthroscopic centre, and centre of the inferior glenoid circle relative to the geometric centre were measured. To simulate anterior glenoid bone loss, imaginary sequential osteotomies were created 0°, 22...

The management of glenoid bone loss is a major challenge in both complex primary and revision arthroplasty surgery. To deal with this problem, a number of techniques have been advocated, although there has been no previous systematic review of the literature. In the present review, we have attempted to identify a coherent strategy for addressing this problem, taking into account the degree of bone loss, the advantages and limits of standard implants, bone reconstruction techniques and the use of customized prostheses...

Bone reconstruction for management of glenohumeral instability to reduce postoperative recurrence rates is increasingly emphasized in our literature. Unfortunately, significant complication rates are associated with these procedures, particularly in the United States where training in bony glenoid reconstruction may be limited. The alternative of early intervention, specifically surgical treatment of first-time shoulder dislocation, could result in glenoid bone preservation and overall improvement in the results of soft-tissue stabilization procedures...

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 of glenoid surface area but flattening of the concavity due to medialization of the fragment...

BACKGROUND: Total shoulder arthroplasty for end-stage glenohumeral arthritis with severe glenoid bone loss poses a unique challenge for shoulder surgeons. Current surgical solutions are limited and associated with high complication rates. We hypothesized that a custom-made computer-aided design-computer-aided manufacturing (CAD-CAM) total shoulder replacement (TSR; Stanmore Implants Worldwide, Elstree, UK) resembling a total hip prosthesis could offer a reliable alternative for this challenging subset of patients...

BACKGROUND: Revision of failed shoulder arthroplasty is often associated with poor results and a high rate of complications. Significant humeral bone loss after removal of long stems poses a considerable surgical challenge. Therefore, the aim of our study was the evaluation of the clinical and radiologic outcome of cemented long-stem humeral components in revision reverse shoulder arthroplasty with a minimum 5 years' follow-up. METHODS: Between June 2001 and June 2009, revision reverse shoulder arthroplasty using long-stem cemented humeral components was performed in 124 patients...
