The wrist represents a complex anatomic region in the human extremity and a highly functional and intricate structural joint. Most perilunate injuries result from a staged disruption of the ligamentous structures. Forces may be directed through the carpal bones themselves resulting in a fracture. Early anatomic reduction of any carpal malalignment is of the utmost importance. Unfortunately, eve...

Trapezoid bone fracture is the least common fracture owing to the fact that it is strictly bounded to scaphoid, capitate and the base of the second metacarpal. Isolated fractures are rarely seen and usually related to the high energy trauma. It is conservatively treated without dislocation. Triquetrum fractures are the second least common fractures among carpal bones. The body fractures are usu...

We have assessed the value of using a simple apparatus,the Carpal Box, in patients with suspected scaphoid fracture, to produce elongated and magnified radiographs of the carpus. The interobserver agreement between 60 observers of standard scaphoid radiographs and longitudinal and transverse Carpal Box radiographs (X-CB) was compared in 11 patients. Three-phase bone scanning was used as a compa...

Radio-carpal joint dislocation, with or without fracture of the radius, is an uncommon injury; only 21 cases have previously been reported. Successful treatments of closed reduction and surgery have also been reported. A 35-year-old right-handed man was injured in a traffic accident and taken to an emergency room of a hospital, where radiographic examination showed a right palmar radio-carpal j...

Compression of the median nerve after Colles’s fracture has been well documented. The causes of compression that have been identified include haematoma within the carpal tunnel (Seddon 1975; Watson-Jones 1 976), hyperextension at the time of the injUry with direct nerve damage (Kirchman 1910; Sterling and Habermann 1973), and healing with excessive callus formation and malunion (Zachary 1945). ...

Perilunate Dislocation Anterior-posterior (AP) view (Figure 1) demonstrates the distal and proximal carpal rows overlapping, as well as a complete radial styloid fracture. Lateral view (Figures 2 and 3) demonstrates dorsal dislocation of the capitate, whereas the lunate remains articulated with the radius. More often seen in young men in their teens to twenties, rather than children or the elde...

Carpal malalignments in malunion of distal radius fracture are considered as an adaptive response of the carpus to loss of normal architecture of the distal radius. This condition leads to mechanical overload, ligament attenuation and progressive dynamic instability around the wrist joint. Radial corrective osteotomy is suggested as a treatment option of carpal malalignment after distal radius ...

Compression neuropathy of the median nerve in the carpal tunnel, better known as the carpal tunnel syndrome, occurs most commonly in adults aged between 30 and 60 years ofage, and is five times more common in women than men.' Any condition that crowds or reduces the capacity ofthe carpal tunnel may initiate the symptoms. Local causes include malaligned Colles' fracture, oedema from trauma or in...

Of all wrist dislocation, the perilunate is the most common type of dislocation. There is ligament disruption typically begins radially and propagates around the lunate. It may be associated with different carpal fractures which the most common pattern is the trans-scaphoid perilunate fracture-dislocation [1,2] which constitutes approximately 50% of these injuries [1-5]. Injury to the distal ra...
