Volar Tilt of the Lunate After Open Reduction Internal Fixation of a Distal Radius Fracture

J Hand Surg Am. 2021 Jun;46(6):520.e1-520.e6. doi: 10.1016/j.jhsa.2020.06.016. Epub 2020 Aug 13.


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.

Keywords: Carpal malalignment; lunate; radius.
