BACKGROUND Identification of fluid in the elbow joint by physical examination alone can be challenging. Ultrasound can assist in the diagnosis of elbow effusion, and guide aspiration of the effusion. OBJECTIVES We illustrate the anatomy and ultrasound guidance technique of a posterior approach to elbow arthrocentesis using examples of normal and pathologic elbow joint ultrasound images. DIS...

Pigmented villonodular synovitis (PVNS) is a rare, idiopathic proliferative disorder of the synovium. While, PVNS of elbow is extremely rare. We report an 82-year-old female patient with 20-year-history of gradually increased PVNS in her left elbow. The multiple masses were located in anterior, medial and lateral of elbow. Her radial, median and ulnar nerves were compressed by the tumor. We res...

OBJECTIVE To evaluate the results from transposition of the triceps for elbow flexion in patients with chronic and complete injury to the upper trunk of the brachial plexus. METHODS This was a retrospective study, including only patients who had biceps grade 0 and triceps grade 5, who underwent anterior transfer of the triceps muscle, performed between 1998 and 2005. The affected side, sex, t...

OBJECTIVE The optimal exposure interval for anteromedial coronoid fractures is unknown. The purpose of this study was to quantitatively compare the osseous and ligamentous exposure of the medial elbow using the flexor carpi ulnaris (FCU)-Splitting and Hotchkiss Over-the-Top approaches. METHODS Forty surgical approaches were performed on 20 fresh-frozen cadaveric elbows using a randomized cros...

INTRODUCTION We report a rare case of a ganglion cyst at the elbow causing neurological symptoms by stretching the superficial radial nerve alone. Ganglia associated with radial nerve palsy at the elbow have been reported previously involving the deep branch of the posterior interosseous nerve and the superficial radial nerve, but not the superficial radial nerve alone. CASE PRESENTATION A 45...

We describe a posterior approach to the elbow which combines the advantages of both splitting and reflecting the triceps. It gives protection to the ulnar nerve and its blood supply during the operation while providing excellent exposure of the distal humerus. During closure, the triceps muscle can be tensioned, thereby improving stability of the elbow. This approach has particular relevance to...

BACKGROUND Tissue adaptations in response to pitching are an expected finding during magnetic resonance imaging (MRI) evaluation of the throwing elbow of adult pitchers. These changes are considered normal in the absence of symptom complaints. It is unclear when during the playing career these tissue adaptations are initiated. HYPOTHESIS Abnormalities in the appearance of the throwing elbow c...

PURPOSE The purpose of this study is to provide a thorough understanding of the anatomy of the cubital tunnel and to outline specific anatomical parameters of the cubital tunnel retinaculum (CuTR) that might aid in the management of ulnar nerve problems. The hypotheses of this study are (1) that the nerve elongates with elbow flexion and (2) that the cross-sectional area of the cubital tunnel i...
