Abstract:

Objective Basing on anatomic characteristics of the second metatarsophalangeal joint, we studied the method and clinical effects of reconstructing  composite tissue defects in the metacarpophalangeal joint by transplantation of modified composite tissue  in the second  metatarsophalangeal joint. Methods  According  to the defects of the metacarpophalangeal joint , modified composite tissue in the second  metatarsophalangeal joint transplantation was conducted to reconstruct metacarpophalangeal joint: total  metatarsophalangeal joint transplantation  in 7 cases, semi-joint transplantation  in 5 cases. Results All reconstructed metacarsophalangeal joints survived in 12 cases. With follow-ups for 6~36 months, all cases have no joint degeneration in X-ray manifestation and the restoration of joint function is satisfying; the function of cases with metatarsophalangeal semi-joint transplantation was better than those in total joint transplantation.. Conclusions It is an effective method to reconstruct composite tissue defects in the metacarpophalangeal joint by transplantation of composite tissue in the second metatarsophalangeal joint.
