Objective To explore the therapeutic effect of Ilizarov technique on wrist scar contracture deformity. Methods Seven patients with wrist scar contracture deformity were treated with Ilizarov technique from April 2017 to January 2020(3 males and 4 females). The age ranged from 12 to 52, with an average of 24 years old. There were 2 cases of left hand, 1 case of left wrist, 4 cases of right wrist. Scar hyperplasia occurred in 2 cases due to wound infection, 1 case due to boiling water scald and 4 cases due to flame burn. Scar formation last from 6 months to 34 years, with an average of 7 years. The wrist function was evaluated according to Mayo score, the function was good in 5 cases and poor in 2 cases before operation. Results The deformity of wrist was corrected. The measurement of neutral position of the wrist was 0°. The carpal flexion could reach 55~70°, and the dorsi extension could reach 0~55°. The postoperative follow-up was conducted for 5 to 24 months, with an average of 15 months. There were no complications such as needle tract infection and extremity numbness . At the last follow-up, wrist function was evaluated according to Mayo score. The function was good in 4 cases, fair in 3 cases, which were significantly improved compared with preoperative results. Conclusions Ilizarov technique is safe and effective in the treatment of wrist scar contracture deformity, which provides a new method for limb function reconstruction after burns.
