Abstract:
Objective To explore the efficacy of simultaneous reconstruction of composite tissue defects in two adjacent metacarpophalangeal joints of hand by split the 2nd toes.Methods From December 2006 to December 2011,the second toe composite flap pedicled with the dorsalis pedis artery-first,second metatarsal dorsal artery-dorsal artery were designed,and split it into the second metatarsophalangeal joint composite flap pedicled with the dorsalis pedis artery-first dorsal metatarsal artery-tibial artery and the proximal interphalangeal joint composite flap pedicled with dorsalis pedis artery-second dorsal metatarsal arteryfibular dorsal artery.Then they were used to repair composite tissue defects in two adjacent metacarpophalangeal joints of hand at the same time after reconstruction.Results This group includes 14 metacarpophalangeal joints of 7 cases,twelve joints was successful,two joints of 1 case to give up because the first dorsal metatarsal artery variation.At 6-24 months follow-up study in 12 out of 14 cases showed that there was no joint degeneration in X-ray manifestation and the recovering of joint function was satisfying.According to the function evaluation standard of reconstraction of thrumb and finger issued by Hand Surgery Society Chinese Medical Association,the excellent and good rate was 83.3％.Conclusion It is feasible to reconstruct of composite tissue defects in two adjacent metacarpophalangeal joints of hand at the same time by split the 2nd toes,and can effectively improve the functions of injury metacarpophalangeal joint.
