Reconstructing finger hemiarthrosis injury with free second toe hemiarthrosis graft

Abstract

Objective To report the clinical results of applying free second toe hemiarthrosis to repair finger hemiarthrosis injury,and discussed the countermeasures of relative problems. Methods From June 2005 to January 2010, thirteen fingers of 13 patients with traumatic finger joint injury had repaired by using vascularized second toe hemiarthrosis graft. Results All 13 grafted fingers survived,and all wounds were primary healing.The time of follow-up was between 1.5 and 4.5 years,average of 3.2 years.All grafted joints were healed and the remaining joints were normal in morphology and structure, except for 1 patient subluxation with dorsal slightly convex.No degenerative changes happened to the grafted joints.No pain and no joint instability phenomenon.Nonunion and re-fracture phenomenon did not appear.The average extension of joint motion was 0°.The average flexion was 80°.Healing of the foot donate areas were satisfactory,and did not affect walking function.Using TAM assessment method of the hand joint function,the excellent rate was 90％. Conclusion The way of using free second toe hemiarthrosis to repair finger hemiarthrosis injury could achieve satisfactory clinical efficacy.To completed set-up of transplanted joint structure and function units,a delicate surgery were improved to be important factors of the surgical treatment.
