Abstract:
The pathophysiology of carpal adaptations after fracture of the distal radius is incompletely understood. We report 5 patients who had normal carpal alignment on injury radiographs that developed marked volar angulation of the lunate during recovery from volar plate fixation of a fracture of the distal radius. There were no signs of alteration of the carpal ligaments. Two patients had similar volar tilt on the contralateral side. The cause and optimal treatment of carpal malalignment after restoration distal radial alignment are unclear.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
