Transecting the transverse carpal ligament (TCL) is a routine procedure to surgically treat carpal tunnel syndrome; yet, its mechanical consequences on carpal bones are unclear. In this study, our intent was to perform a computational analysis of carpal biomechanics resulting from TCL release. A three-dimensional finite element model of the wrist was constructed, which included all the carpal b...

Although nearly every combination of intercarpal arthrodeses has been described, excision of the scaphoid and fusion of the remaining carpal bones in neutral alignment was a unique concept when it was introduced nearly 20 years ago. This time-tested and established procedure that is commonly known as the 4-corner or 4-bone arthrodesis is based on the principle that the radiolunate articulation ...

We compared the long-term outcome in 61 patients (62 fractures) treated operatively or conservatively for an acute fracture of the carpal scaphoid. A total of 30 fractures was randomised to conservative treatment using a cast and 32 to operative treatment using a Herbert bone screw. The duration of sick leave was shorter for patients treated by operation, but this was only significant in patien...

The management of pain, stiffness and weakness of the wrist following unsuccessful conservative treatment of fractures of the scaphoid or of Kienb#{246}ck’s disease is a difficult problem. The result of excision of the affected bone is unpredictable and arthrodesis is a major procedure which leaves a disability. To avoid these disadvantages Stamm (1944) suggested arthroplasty of the wrist by ex...

Injuries to the wrist often present problems of accurate diagnosis and effective treatment (MacAusland 1944, B#{246}hler1956, Cave 1958, Aitken and Nalebuff 1960). Those associated with fractures are usually demonstrated by proper radiographs, but even these injuries may be missed (Soto-Hall and Haldeman 1941, Speed 1950). Dislocation of the scaphoid bone may occur after apparently successful r...

BACKGROUND Scaphoid fractures are the most common type of carpal fractures. OBJECTIVES The aim of the study was to compare the diagnostic value of panoramic and conventional radiographs of the wrist in scaphoid fractures. PATIENTS AND METHODS The panoramic and conventional radiographs of 122 patients with acute and chronic wrist trauma were studied. The radiographs were analyzed and examine...

We prospectively reviewed 14 patients with deficiency of the proximal pole of the scaphoid who were treated by rib osteochondral replacement arthroplasty. Improvement in wrist function occurred in all except one patient with enhanced grip strength, less pain and maintenance of wrist movement. In 13 patients wrist function was rated as good or excellent according to the modified wrist function s...
