Congenital fusion of the trapezium and trapezoid.

چکیده
We report an unusual case of carpal coalition between trapezium and trapezoid in a 54-year-old man who was diagnosed after a pain in left wrist following a night's sleep. The patient was otherwise asymptomatic.

The distal row, which is more stable and moves as a unit, consists of the trapezium, the trapezoid, the capitate, and the hamate. The distal row forms a rigid, supportive transverse arch upon which the five metacarpals of the hand are supported. The trapezium articulates with the first metacarpal, the trapezoid with the second, and the capitate with the third one. The capitate and trapezoid are...
متن کاملCarpal Coalitions; Failures of Differentiation of the Carpus: A Description of Cases
Synostosis of carpal bones originates from lack of cavitation at the site of the future joint space with subsequent chondrification and ossification during the 4 to 8 weeks of intrauterine life. It is mostly seen as a chance finding discovered on radiographs. These coalitions are often asymptomatic, but can give complaints after trauma. We report six patients with different congenital carpal co...
متن کاملMultiple carpometacarpal dislocations and an ipsilateral scapho-trapezium-trapezoid fracture-dislocation: a rare pattern of injury.
We report a rare case of simultaneous dorsal dislocation of 4 ulnar carpometacarpal joints and dorsoradial dislocation of the trapezium with an associated fracture of the scaphoid tuberosity. The injuries were diagnosed early and treated successfully with closed reduction and transfixation using Kirschner wires. The functional results were excellent at 17-month follow-up.
متن کاملTraumatic volar dislocation of the trapezoid with acute carpal tunnel syndrome.
1 reported the first case of a dislocation of the trapezoid. Since that time there have been Ͻ25 reported cases in the literature. 2-24 Most dislocations are accompanied by a fracture of the adjacent carpals or metacarpals and usually are dorsal in direction. Palmar dislocation of the trape-zoid is distinctly more unusual, with Ͻ10 reported cases. 3, 4,6,22,24 A volar disloca-tion with accompan...
متن کاملA 3D quantitative comparison of trapezium and trapezoid relative articular and nonarticular surface areas in modern humans and great apes.
The structure and functions of the modern human hand are critical components of what distinguishes Homo sapiens from the great apes (Gorilla, Pan, and Pongo). In this study, attention is focused on the trapezium and trapezoid, the two most lateral bones of the distal carpal row, in the four extant hominid genera, representing the first time they have been quantified and analyzed together as a m...
