BACKGROUND The impact of a recurrent defect on the outcome after rotator cuff repair has been controversial. The purpose of this study was to evaluate the functional and anatomic results after arthroscopic repair of large and massive rotator cuff tears with use of ultrasound as an imaging modality to determine the postoperative integrity of the repair.

BACKGROUND Complex acute proximal humeral fractures may require prosthetic replacement of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been suggested as an alternative to hemiarthroplasty in the management of such fractures. This study compared the functional outcomes of RSA with hemiarthroplasty in patients with acute proximal humeral(More)
BACKGROUND Surgery on the posterior aspect of the shoulder has become accepted practice for a number of pathological conditions affecting the scapula and the glenohumeral joint. Despite this trend, the anatomy of the posterior branch of the axillary nerve has not been well characterized. The purpose of the present study was to determine the innervation(More)
Elbow stability relies on a complex interaction between the bony articulations of the elbow joint, the capsuloligamentous structures, and dynamic muscle restraints. Understanding the functional anatomy of the elbow and the relative contribution of the various elements to elbow stability is important in developing a strategy for diagnosis and management.(More)
BACKGROUND Reverse total shoulder arthroplasty (RSA) is a relatively recent concept that provides further options in the management of cuff-deficient shoulder disorders. While early results utilizing the Delta III prosthesis (DePuy, Warsaw, IN) have been promising, there is limited data in the literature on outcomes utilizing differing prosthetic designs.(More)
INTRODUCTION Dislocation of the elbow with associated fractures of the radial head and the coronoid process of the ulna have been referred to as the terrible triad of the elbow because of the difficulties in treating this injury and the poor outcomes. MATERIALS AND METHODS There were 23 patients (24 elbows) available for evaluation with this injury during(More)
Cystlike cortical defects appearing after minor greenstick fractures in children have occasionally been described. These lesions are typically asymptomatic and appear just proximal to the fracture line within the area of subperiosteal new bone formation. Although the pathogenesis of these lesions remains in doubt, complete resolution is the rule, with no(More)
Rotator cuff repair is one of the most common surgical procedures done in the shoulder. Traditionally, repair has required an open incision with release of a portion of the deltoid from the acromion. In the past decade, an arthroscopically-assisted, mini-open approach has gained popularity. This has been facilitated by advances in the use of arthroscopy.(More)
BACKGROUND AND OBJECTIVES Ultrasound (US) imaging facilitates catheter placement adjacent to the most appropriate elements of the brachial plexus, which for shoulder surgery are the C5YC6 roots or superior trunk. Therefore, it was investigated whether such placement would improve catheter effectiveness compared to placement with traditional techniques. (More)
