Abstract
Dislocations involving the carpus are among the most devastating injuries of the wrist.
The more commonly encountered perilunate dislocations occur as the final stage of
a mechanism progressing in a radial to ulnar direction. These injuries often are missed
initially, potentially leading to serious complications. Patients presenting with
high energy injuries about the wrist must be scrutinized carefully using standard
wrist radiography and occasionally tomography. All dislocations of the carpus require
prompt reduction. Better results from perilunate and lunate dislocations can be expected
when dorsal and volar surgical approaches are used and the scapholunate interosseous
ligament is repaired. Wrist stiffness, posttraumatic arthritis, and median nerve dysfunction
may complicate carpal dislocations, even after early surgical attention.
