: 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...

OBJECTIVE: To determine whether 3D-MR osseous reformats of the shoulder are equivalent to 3D-CT osseous reformats in patients with glenohumeral instability. MATERIALS AND METHODS: Patients with glenohumeral instability, who were to be imaged with both CT and MRI, were prospectively selected. CT and MR were performed within 24 h of one another on 12 shoulders. Each MR study included an axial 3D isotropic VIBE sequence. The image data from the isotropic VIBE sequence were post-processed using subtraction and 3D software...

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...

PURPOSE: To assess the ability of 3-dimensional (3D) magnetic resonance imaging (MRI, 1.5 and 3 tesla [T]) to quantify glenoid bone loss in a cadaveric model compared with the current gold standard, 3D computed tomography (CT). METHODS: Six cadaveric shoulders were used to create a bone loss model, leaving the surrounding soft tissues intact. The anteroposterior (AP) dimension of the glenoid was measured at the glenoid equator and after soft tissue layer closure the specimen underwent scanning (CT, 1...

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...
