PURPOSE Several techniques for ulnar-shortening osteotomies have been described in recent years, reflecting the difficulties that sometimes are encountered in what seems to be a relatively simple procedure. We describe the use of a simple step-cut ulnar-shortening osteotomy stabilized with a lag screw and a palmarly placed 3.5-mm neutralization plate. METHODS Twenty-nine patients had the surg...

PURPOSE This study was conducted to evaluate the ability of sonography to visualize the ulnar nerve at Guyon's canal and the common peroneal nerve dorsal to the fibular head and to test for correlations between nerve measurements and subject characteristics. METHODS We used a 5-12-MHz linear-array transducer in sonographic evaluation of 15 healthy adult volunteers. We evaluated the correlatio...

Ulnar neuropathy is caused by compression of the ulnar nerve in the upper extremity, frequently occurring at the level of the elbow or wrist. Rarely, ulnar nerve entrapment may be seen proximal to the elbow. This report details a case of ulnar neuropathy diagnosed and localized to the arcade of Struthers with electromyography (EMG) and ultrasound (US) imaging and confirmed at time of operative ...

High bifurcation of the brachial artery seems to be a common variation, which can occur in many different forms, and some of them might be rather rare. We report an unusual case of bilateral high bifurcation of the brachial artery in a male cadaver. On the right arm, high origin of the ulnar artery as superficial ulnar artery was observed. The brachial artery continued and divided at the level ...

Ulnar sided wrist pain is a common site for upper extremity disability. Ulnar impaction syndrome results in a spectrum of triangular fibrocartilage complex (TFCC) injuries and associated lunate, triquetrum, and ligamentous damage. Patients commonly present with insidious ulnar sided wrist pain and clicking, and a history of trauma or repetitive axial loading and rotation. In this case series, t...

Extensor carpi radialis brevis (ECRB) sarcomere length was measured in seven patients using intraoperative laser diffraction. Sarcomere length was measured with the forearm in one of four positions: wrist in neutral with regard to radial-ulnar deviation and forearm in neutral rotation, wrist in ulnar deviation and forearm in neutral rotation, wrist in neutral and forearm in pronation, and wrist...

OBJECTIVE This research examines individual differences in the wrist postures adopted during the use of two pointing devices (mouse and trackball). DESIGN A multiple case study of twelve participants was employed. BACKGROUND The use of pointing devices may lead to musculoskeletal discomfort and injury as a consequence of prolonged exposure to postures involving wrist extension and ulnar dev...

Introduction Variations of the arterial patterns in the upper limb have been the subject of many anatomical studies due to their high incidence. Brachial artery is the main artery of the arm. It is a continuation of axillary artery at the lower border of teres major muscle. It usually terminates at the level of neck of radius in the cubital fossa by dividing into radial and ulnar arteries. The ...

conclusions this study did not show that distal radius anatomical indices including the radial height, radial inclination, ulnar variance and volar tilt influence perilunate fracture dislocation as risk factors. background distal radius radiographic indices may play a role as risk factors in pathogenesis of kienbock’s disease, scaphoid fracture and non:union:. perilunate fracture dislocations a...
