ABSTRACT
PURPOSE: We report clinical and radiographic outcomes after internal fixation of intraarticular volar fractures of the middle phalanx base. METHODS: A retrospective review was conducted on 11 patients who had been treated with miniplate or screw for acute proximal interphalangeal joint fracture, after adjusting for the cases excluding severe comminuted or open fractures. The participants consisted of 9 males and 2 females, with average age of 43.7 years and with average follow-up period of 15.2 months. Bony union, change of articular side were examined through radiographs, and functional results were evaluated by means of the total active range of motion (TAM) and the disabilities of the arm, shoulder, and hand (DASH). RESULTS: Of 11 cases of a finger fracture, 7 cases were fixed by miniplate with screws and 4 cases by screws alone. At the final follow-up retrospection, the average range of proximal interphalangeal joint motion was 95degrees, the average TAM was 243.2degrees, and the average DASH score was 7.4. Average 2.8 months was spent from the finger fracture to bony union. There was no case of degenerative change. CONCLUSION: Open reduction and internal fixation with screws for acute intraarticular fractures of the middle phalanx base showed favorable results in our study and it could be one of recommendable treatment options.
