Abstract:
Objective To explore the effect of shifting the little finger abductor muscle and cutting open the metatarsophalangeal joint dorsal articular capsule to improve the appearance and function of reconstructed thumb.Methods From August 2007 to May 2012,twelve cases of Ⅳ°or Ⅴ°defect of thumb were repaired by free transplantation of the second toes with metatarsophalangeal joint.During operation,using the abductor muscle of little finger to reconstruct palmar opposition function,cutting open the joint capsule of metatarsophalangeal joint,adjusting the tension of the joint by the little finger abductor muscle and toe short extensor muscles,which were used to improve the appearance and function of reconstructed thumb.Results Twelve reconstructed thumbs all survived.Followed up from 6 to 24 months,the appearance and function were improved obviously.According to the evaluation trial standards,nine cases were optimal and 3 cases were good.Conclusion The shift of the little finger abductor muscle could reconstruct palmar opposition function,combined with metatarsophalangeal joint dorsal articular capsule incision and adjusting joint tension,could improve the appearance and function of reconstructed thumb.The effect of operation was satisfied.
