Management of proximal and distal biceps tendon pathology is evolving. The long head of the biceps tendon, if inflamed, may be a pain-producing structure. In appropriately indicated patients, a symptomatic long head of the biceps tendon can be surgically managed via tenotomy, tenodesis, and/or superior labrum anterior to posterior repair. In some patients, primary superior labrum anterior to posterior pathology can be managed via biceps tenodesis. Determining which procedure is most appropriate and which technique and implant are preferred for a given patient with biceps tendon pathology is controversial...

A phantom study was conducted to determine bias in motion and bias at zero motion of radiostereometric analysis (RSA) for evaluating implant relative displacement in reverse total shoulder arthroplasty (RTSA). A Sawbones shoulder phantom was fitted with a RTSA implant set and 13 tantalum markers. The model was fixed to a manual micrometer, providing controlled movements though fifteen known increments in translation and twelve increments in rotation (0.02-5.00 mm and 0.1-6.0°), along each translation and rotation axis...

INTRODUCTION: Management of periprosthetic shoulder infections (PSIs) still remains challenging. We conducted a retrospective case study to assess the outcomes of definitive articulating antibiotic spacer implantation in a cohort of elderly, low-demanding patients. We hypothesized that in patients with low functional demands seeking pain relief with chronic PSIs, treatment with a definitive articulating antibiotic spacer would lead to satisfying results concerning eradication of the infection, improvement of pain, and improving shoulder function...

Recurrent anterior shoulder instability is commonly associated with defects of the anterior glenoid rim. Substantial osseous defects significantly diminish the glenohumeral stability and require a bony augmentation, either by a coracoid transfer or free bone grafting procedure. Both reconstructive techniques have been applied for a long time and evaluated biomechanically and clinically. Although neither treatment option has been recognized as clearly superior, both comprise certain advantages and disadvantages...

PURPOSE: A crucial step of the Latarjet procedure is the fixation of the coracoid process onto the glenoid. Multiple problems associated with the fixation have been described, including lesions of the suprascapular nerve due to prominence of the screw or bicortical drilling. The purpose of the present study was to evaluate whether monocortical fixation, without perforating the posterior glenoid cortex, would provide sufficient graft stability. METHODS: Coracoid transfer was performed in 14 scapula models (Sawbones®, Composite Scapula, 4th generation)...

BACKGROUND: Conventional computed tomography (CT) is not accurate for glenoid version measurement. This study sought to examine the feasibility of an interdepartmental protocol implemented between orthopedic surgery and radiology departments for acquisition of anatomic axial CT images and to validate the glenoid version measured through such a protocol. MATERIALS AND METHODS: Data of 30 conventional CT scans of 10 normal and 20 osteoarthritic glenoids were transferred to clinical 3-dimensional imaging software by a radiology technician trained for the study...

PURPOSE OF REVIEW: To review the etiology, classification, presentation, evaluation, treatment strategy, and outcomes in overhead athletes with partial thickness rotator cuff tears. RECENT FINDINGS: Despite advances in surgical repair techniques, return to play following surgical repair of partial rotator cuff tears remains modest at best. Overhead athletes may be particularly prone to rotator cuff pathology due to the supraphysiological strains within the tendon during the throwing motion, as well as mechanical stress with contact between the undersurface of the rotator cuff and the glenoid...

BACKGROUND: Anterior shoulder dislocations in young patients are associated with high rates of recurrent instability. Although some surgeons advocate for surgical stabilization after a single dislocation event in this population, there is sparse research evaluating surgical treatment for first-time dislocators. METHODS: Patients undergoing surgical stabilization for anterior shoulder instability were prospectively enrolled at multiple institutions from 2015-2017 and stratified by number of dislocations before surgery...

REVIEW
C Gerhardt, L J Lehmann
In recent years, the understanding of shoulder fractures has changed due to the progress of arthroscopy. In addition to the cosmetic result, the access morbidity, particularly the integrity of the subscapularis muscle in glenoid and scapular fractures, must be mentioned as an advantage of a minimally invasive approach. Furthermore, necessary secondary interventions, e. g. hook plate removal, can be prevented or minimized by modern implants and arthroscopic techniques.However, the available data and publications are almost exclusively limited to technical notes or small case series, so statements about faster recreation or potential reduction of infection risk cannot be made...

Background: Arthroscopic stabilization is the most broadly used surgical procedure in the United States for management of recurrent shoulder instability. Latarjet coracoid transfer has been considered a salvage surgical procedure for failed arthroscopic repairs or cases of significant glenoid bone loss; however, with recent literature suggesting reduced risk of recurrent instability with Latarjet, several surgeons have advocated its broader utilization as a primary operation for treatment of shoulder instability...

BACKGROUND: Glenoid component failure is a prevalent mechanical complication of anatomic total shoulder arthroplasty. The objective of this study was to identify surgeon-controlled factors that may be addressed to reduce the rate of glenoid component failure that is sufficiently symptomatic to merit surgical revision. METHODS: We reviewed the clinical and radiographic features of 215 total shoulder arthroplasties that we revised for symptomatic glenoid component failure...

BACKGROUND: The purpose of this study was to evaluate the posterior ridge of the greater tuberosity, a palpable prominence during surgery, as a landmark for the posterior approach to the glenohumeral joint. METHODS: Twenty-five human cadaveric shoulders were dissected. In 5 cases, a full-thickness rotator cuff tear was present. The posterior surgical anatomy was defined, and the distance from the ridge to the interval between the infraspinatus (IS) and teres minor (TM) muscle, the distance from the ridge to the inferior border of the glenoid (IBG), and the distance between the IS-TM interval and the IBG were determined...

BACKGROUND: Scapula fractures are rare injuries that are generally treated nonoperatively. When surgery is performed, it is commonly undertaken through the posterior approach, which can be invasive and unforgiving on the soft tissues. We describe an alternative safe approach between teres major and minor that remains deep to a fascial sling formed by the combined infraspinatus and teres minor fasciae and deep to the primary nerve to teres minor, which is a terminal branch of the axillary nerve...
