OBJECTIVE: To introduce the repair of distal extensor tendon rupture of the finger by the purse-string burial method.
METHODS: On the back of the distal interphalangeal joint of the affected finger, an oval suture was designed with the long axis parallel to the midline of the finger and the short axis parallel to the articular surface, and the entry and exit points of the needle were located at one end of the short axis. A 1/2-arc, 4 x 12 circular needle with 1-0 silk thread is used. The needle is inserted and removed across the joint, forming a loop and knotted, and the thread is buried under the skin, and another loop is sewn in the same way. Postoperative day and night interval finger rest extension position was fixed for one to three weeks.
RESULTS: According to the evaluation criteria for the efficacy of hammer finger developed by Patel et al, 12 cases in this group were followed up from 6 to 12 months after surgery, with an average of 7 months, of which 2 (17%) were excellent, 7 (58%) were good, 2 (17%) were moderate, and 2 (17%) were poor. The overall excellent rate was 75%.
CONCLUSION: The buried wire method for hammer finger deformity is a good procedure.
