Abstract
Objective To explore the clinical efficacy of reconstruction of extensor tendon insertion in situ for treatment of tendinous mallet finger deformities. Methods From August 2015 to July 2017, 10 cases of tendinous mallet finger deformities were treated with the modified method. Specifically, three bone holes were drilled obliquely by 15 gauge needle at the distal phalanx dorsal base of the injured finger. The proximal of extensor tendon was fixed to the distal phalanx dorsal base with 4-0 tendon suture through the bone holes. Four weeks after the operation, external fixation was removed and moderate active flexion and extension exercises were started. After 8 weeks, the rehabilitation training could be gradually strengthened. Results All the cases were follow-up from 3 to 10 months with an average of 7 months. The wounds all achieved primary healing. The mallet finger deformities were corrected. There is no pain in the movement of the injured finger. According to the evaluation system of Crawford mallet finger evaluation system, the results were excellent in 8 cases and good in 2 cases. Conclusion It is a simple and effective surgical method to reconstruct the extensor tendon insertion by using this modified method. Key words: Surgical procedures, operative; Treatment outcome; Tendinous mallet finger; Extensor tendon insertion
