[A case of inveterate metacarpo-phalangeal dislocation of the thumb treated surgically by the Kessler method]

A case of inveterate dorsal dislocation of the MCP joint of the thumb treated by open reduction and tendon reinforcement of the volar capsule. The paper reports rare cases of inveterate, complete dorsal dislocation of the thumb MCP joint. After open reduction there was a full passive flexion but dorsal dislocation recurred. The tendency to return of dislocation was abolish by tendon reinforcement of the capsule of the joint described by Kessler. Follow up studies revealed no significant instability, the range of motion was between 20 degrees and 55 degrees of flexion.
