The role and implementation of metacarpophalangeal joint fusion and capsulodesis: indications and treatment alternatives.

Successful surgical reconstruction of the basilar thumb joint requires a thorough knowledge of the longitudinal intercalated collapse that may occur with this condition. Evaluation of the hyperextended thumb MCP joint and appropriate treatment are instrumental to successful basal joint reconstruction. Stabilization of the MCP joint helps maximize return of a pain-free, efficient pinch mechanism. A useful guide to specific reconstructive methods for the MCP joint is presented in Table 1.
