BACKGROUND: Off-track Hill-Sachs lesions have been associated with high rates of recurrent shoulder instability. Both arthroscopic Bankart with remplissage and modified Latarjet have been described to treat off-track Hill-Sachs lesions. However, few comparative studies exist between the 2 techniques in heterogeneous populations. HYPOTHESIS: Remplissage would have similar recurrence rates and clinical outcomes to modified Latarjet for off-track Hill-Sachs lesions with subcritical glenoid bone loss...

BACKGROUND: Total shoulder arthroplasty remains an effective procedure for shoulder pain relief. Despite the negative effect of abnormal glenoid morphology and specifically retroverted and posteriorly subluxated glenoids, there is no consensus for management of B2 glenoids in total shoulder arthroplasty. The purpose of this study was to compare the outcomes and complication rates for B2 glenoid techniques so as to provide a baseline understanding of the current state of treatment of this pathology...

PURPOSE: To compare the outcomes of total shoulder arthroplasty (TSA) with posterior capsule plication (PCP) and reverse shoulder arthroplasty (RSA) in patients with primary osteoarthritis, posterior subluxation, and bone loss (Walch B2). PATIENTS AND METHODS: All shoulders undergoing anatomic TSA with PCP were retrospectively identified (group 1, G1) and compared to shoulders undergoing RSA (group 2, G2) for Walch B2 osteoarthritis. There were 15 patients in G1 (mean (SD) age and follow-up of 70...

Recurrent anterior shoulder instability is associated with glenohumeral bone loss. Glenoid deficiency compromises the concavity-compression mechanism. Medial Hill-Sachs lesions can result in an off-track humeral position. Anterior glenoid reconstruction or augmentation prevents recurrence by addressing the pathomechanics. In Bristow and Latarjet procedures, the coracoid process is harvested for conjoint tendon transfer, capsular reinforcement, and glenoid rim restoration. Complications and the nonanatomic nature of the procedure have spurred research on graft sources...

The purpose of this study was to examine outcomes after cryopreserved tri-cortical iliac crest allograft reconstruction for glenoid bone loss in patients with shoulder instability. 10 patients completed the required assessments at a mean follow up of 4.5 years. At final follow up, mean ASES was 92 ± 12, mean WOSI was 315 ± 319, with good range of motion. None of the final radiographs demonstrated graft resorption or failure of hardware. The data demonstrated that patients who were treated with glenoid bone grafting with cryopreserved tri-cortical iliac crest allograft can expect good range of motion and functional capacity...

PURPOSE: A group of patients affected by bone loss in the context of recurrent anterior shoulder instability were treated arthroscopically with a modified Eden-Hybinette technique since 2005. The last modification was made in 2013, consisting of fixation using a pair of specifically designed double round Endobuttons, which secure the bone graft to the glenoid rim placed through a guide. This report describes patients operated on after this last modification. No reports have described the results of this technique, and the purpose of this study was to assess early clinical and radiological results of an arthroscopic bone block procedure with double round Endobutton fixation...

BACKGROUND: Corrective anterior reaming is an accepted method for addressing retroversion in a biconcave retroverted (Walch classification, type B2) glenoid in anatomic total shoulder arthroplasty. However, concern still exists regarding early glenoid component failure in the setting of severe retroversion, which may be related to loss of component containment and/or violation of subchondral bone resulting from reaming. The goal of this study was to determine what characteristics of B2 glenoids are less amenable to corrective reaming by virtually implanting anatomic glenoid components...

Background: Recurrent shoulder dislocation and anterior instability are most commonly attributed to pathology of the capsulolabral complex with the presence of bony loss at the humeral and glenoid surfaces. Unassessed bone loss has been a cause of failure of primary soft tissue procedures or recurrence of symptoms, despite adequate address of soft tissue pathology. Purpose: To study the anthropometric and radiologic dimensions of the coracoid in relation to glenoid bone loss, its adequacy in filling glenoid defects in an Indian population, and whether the choice of surgical technique (congruent arc vs classical) and graft positioning alters the surgical results...

The reverse shoulder arthroplasty facilitates surgical treatment of primary and revision shoulder with rotator cuff and bone deficiencies. Wear pattern classifications and a logical treatment approach for glenoid bone loss enable the surgeon to address a difficult series of problems in the reconstructions where the glenoid might not otherwise be able to support the implants. Bone grafting using the native humeral head in primary cases, and in revision cases, iliac crest are the most reliable sources for structural grafts for the worn or deficient glenoid vault...

PURPOSE: Glenoid loosening is a common cause of reverse total shoulder arthroplasty (RTSA) failure, and grafting of the glenoid is often required for revision due to bone loss due to the central peg in most glenoid baseplates. Helical blades have been used in the hip to optimize bone fixation in proximal femoral fracture. This study presents the initial results of specifically designed helical blade in the shoulder to optimize glenoid bone fixation and preservation as part of RTSA. METHODS: Thirty-five patients underwent RTSA with glenoid helical blade fixation...

BACKGROUND: Anterior shoulder instability with significant glenoid bone loss is a challenging condition. The open Latarjet procedure is the established standard treatment method in this setting, but there is an increasing use of the arthroscopic technique. PURPOSE: To systematically review the current evidence in the literature to ascertain if the open or arthroscopic Latarjet procedure resulted in improved patient outcomes. STUDY DESIGN: Systematic review and meta-analysis...

BACKGROUND: Few studies have evaluated the success of the Latarjet procedure for recurrent anterior glenohumeral instability in the contact or collision athlete. The purpose of this study was to evaluate the return-to-sport and functional results of the Latarjet procedure in this select group. METHODS: One hundred and nine consecutive contact or collision athletes (112 shoulders) treated with an open Latarjet procedure for recurrent anterior glenohumeral instability were retrospectively identified...

BACKGROUND: There is currently no consensus regarding the amount of posterior glenoid bone loss that is considered critical. Critical bone loss is defined as the amount of bone loss that occurs in which an isolated labral repair will not sufficiently restore stability. PURPOSE: The purpose is to identify the critical size of the posterior defect. STUDY DESIGN: Controlled laboratory study. METHODS: Eleven cadaveric shoulders were tested...

BACKGROUND: Bony defect situations are a common problem in revision arthroplasty of the shoulder and are the cause of the complexity of the procedure. Aseptic and septic loosening as well as difficult implant removal can result in humeral and/or glenoid bone loss. PLANNING: A careful preoperative imaging is needed to estimate the extent of the bony defect and to enable precise planning of the bone reconstruction and the required implants. However, the size of the defect needs to be re-evaluated intraoperatively after removal of the implant components and any larger defects have to be addressed appropriately...

BACKGROUND: Glenoid morphology and rotator cuff muscle quality are important anatomic factors that can impact longevity of the glenoid component following total shoulder arthroplasty (TSA). We hypothesized that rotator cuff muscle fatty infiltration is associated with increased pathologic glenoid bone loss in glenohumeral osteoarthritis (OA). METHODS: We retrospectively reviewed 190 preoperative computed tomography (CT) scans of 175 patients (mean age, 66 years; range, 44 to 90 years) who underwent TSA for the treatment of primary glenohumeral OA...

Removal of a cemented glenoid component often leads to massive glenoid bone loss, which makes it difficult to implant a new glenoid baseplate. The purpose of this study was to demonstrate the feasibility of revisions with a completely convertible system and to report clinical and radiographic results of a retrospective review of 13 cases. Between 2003 and 2011, 104 primary total shoulder arthroplasties (TSAs) were performed with an uncemented glenoid component in our group. Of these patients, 13 (average age, 64 years) were revised to reverse shoulder arthroplasty (RSA) using a modular convertible platform system and were included in this study...

Complex glenoid bone deformities present the treating surgeon with a complex reconstructive challenge. Although glenoid bone loss can be encountered in the primary setting (degenerative, congenital, post-traumatic), severe glenoid bone loss is encountered in most revision total shoulder arthroplasties. Severe glenoid bone loss is treated with various techniques including hemiarthroplasty, eccentric reaming, and glenoid reconstruction with bone autografts and allografts. Despite encouraging short- to mid-term results reported with these reconstruction techniques, the clinical and radiographic outcomes remain inconsistent and the high number of complications is a concern...

BACKGROUND: Glenoid bone loss and capsular deficiency represent critical points of arthroscopic Bankart repair failures. The purpose of this study was to evaluate an all-arthroscopic bone block procedure associated with arthroscopic subscapularis augmentation (ASA) for treating gleno-humeral instability with glenoid bone loss (GBL) and anterior capsulo-labral deficiency. Our hypothesis was that these two procedures could be combined arthroscopically. The feasibility of this technique and its reproducibility, and potential neurovascular complications were evaluated...
