Comparison of two methods in the treatment of finger flexion deformity of scar contracture

Objective To investigate the clinical efficacy, indications and precautions of dual intersecting trapezoid flaps and laterodigital flaps in the treatment of finger flexion deformity of scar contracture. Methods From February 2014 to October 2016, 14 patients (25 fingers) with finger flexion deformity of scar contracture were treated. According to the extension of scar contracture line, dual intersecting trapezoid flaps were used in 7 cases (12 fingers) (group A) and laterodigital flaps were used in 7 cases (13 fingers) (group B). The repair range, infection and necrosis rate, total active motion of inured finger (TAM), extension rate of scar contracture line and reoperation were compared between the two groups. Results All the flaps survived uneventfully. The repair range of group A reached the level of DIP and group B reached the level of PIP. There was no reoperation due to recurrence of scar contracture in both groups, but the satisfaction of group B was lower than that of group A. Conclusion The dual intersecting trapezoid flaps have reliable blood supply and the operation is simple, the repair range of which can reach the level of DIP. They can allow early joint movement. It is a more ideal method for the treatment of finger flexion deformity of trans-articular scar contracture. Key words: Surgical flaps; Finger injuries; Cicatrix; Contracture
