BACKGROUND The aim of surgical management of Kienböck's disease has been proposed to slow the progressive osteonecrosis and secondary carpal damage. The aim of this case series was to evaluate the results of a new technique, combining distal capitate shortening with capitometacarpal fusion for the treatment of Kienböck's disease (Lichtman stage II or stage IIIA) in neutral ulnar variance patien...

anterior transposition of the ulnar nerve is widely implemented for treatment of cubital tunnel ‎syndrome. however, preservation of the extrinsic blood supply of the ‎ulnar nerve may result in better clinical outcomes. fourteen patients with cubital tunnel ‎syndrome, 11 ‎men and 3 women, were treated by anterior subcutaneous transposition of the ulnar nerve. the extrinsic blood supply of the ul...

BACKGROUND AND PURPOSE The purpose of this study was twofold: (1) to determine whether passive wrist flexion and extension goniometric measurements using ulnar alignment, radial alignment, and volar/dorsal alignment were similar or dissimilar and (2) to examine which of these three techniques had the greatest intratester and intertester reliability. SUBJECTS One hundred forty patients (141 wr...

common form of entrapment neuropathy after carpal tunnel syndrome.1 Symptoms which patients report include aching pain on the medial aspect of the elbow, forearm and hand, as well as numbness, tingling, hyperesthesia, or weakness in the distribution of the ulnar nerve (see Norkus and Meyers1 for a more detailed description). Diagnosis rests on clinical findings, confirmed by electrodiagnostic c...

OBJECTIVE To compare the detailed architectural properties of the pronator teres (PT), extensor carpi radialis brevis (ECRB), and extensor pollicis longus (EPL) muscles to evaluate the suitability of PT-to-ECRB and PT-to-EPL surgical procedures. METHODS Muscle physiologic cross-sectional areas and region-specific muscle fiber lengths were measured in cadaveric PT, ECRB, and EPL muscles (n = 1...

Background The location of the ulnar styloid process can be confusing because the radius and the hand rotate around the ulna. The purpose of this study was to identify the absolute location of the ulnar styloid process, which is independent of forearm pronation or supination, to use it as a reference for neutral forearm rotation on lateral radiographs of the wrist. Methods Computed tomography...

BACKGROUND Surgical decompression of the ulnar nerve is effective for cubital tunnel syndrome. However, deep approaches may result in iatrogenic elbow stiffness. This long-term study was to evaluate the range of motion (ROM) of the elbow and functional outcomes after anterior subcutaneous transposition. METHODS A total of 115 patients (78 male and 37 female; mean age: 46.6 years) who underwen...
