Ｂａｒｔｏｎ骨折の治療経験

Abstract

Volar Barton's fracture is an unusual injury. We have treated five cases of volar Barton's fracture at fresh injury. Four cases were treated by open reduction and internal fixation with A-O small T plate. One case had been treated by conservative therapy with cast, but the carpal bone was translocated to volar side lately and proximal carpal instability was caused. So radiocarpal limited arthrodesis was added. Clinical results were evaluated by the Sarmiento system. Three of four cases treated by open reduction and internal fixation were excellent, and one case was good. One case treated by cast was poor, because pain, ROM limitation and loss of grip power had, remained. After arthrodesis the symptoms were improved, and the result became fair. In the case with carpal instability, the instability was caused by the deformity of articular surface of distal radius and the disruption of radiocarpal ligament. In other cases the anatomical reduction was obtained and carpal instability did not develop.
