Abstract

Posttraumatic volar instability of the thumb metacarpophalangeal joint with hyperextensile laxity makes pain and weakness during pinch or grip exercise. Several surgical procedures have been described to eliminate thumb metacarpophalangeal joint hyperextension. We treated a patient who had suffered from volar instability with pain for 17 years using volar plate repair and capsulodesis with suture anchor. The result was successful with satisfactory recovery of the hand function.

Keywords: Metacarpophalangeal joint, Volar instability, Volar capsulodesis
