Multidirectional radiocarpal dislocation without fracture: a case report.

The first reported case of posttraumatic multidirectional instability of the radiocarpal joint is described with a review of the relevant literature. A 31-year-old man sustained a palmar radiocarpal dislocation that also dislocated dorsally with gentle provocation and showed ulnar translation and a dorsal intercalated segmental instability pattern after closed reduction. Treatment consisted of open reduction and internal fixation with 11 weeks of immobilization. Follow-up at 32 months showed excellent clinical and radiographic results. Multidirectional instabilities of the radiocarpal joint can occur with radiocarpal dislocation, and one must look for them when planning treatment. Anatomic realignment of the bones and joints is recommended to allow soft tissue healing and prevention of secondary ligamentous laxity.
