Midcarpal (central carpal) dislocation describes an injury where there is dislocation of the capitate from the lunate, and subluxation of the lunate from the radius. This term is somewhat confusing because some authors use "midcarpal dislocation" to refer generally to perilunate and lunate dislocations.
A four-stage process to describe perilunar instability has been described by Mayfield, where midcarpal dislocation represents stage 3 3.
