Operative treatment for volar plate avulsion fractures of the fingers.

We present our experience with 14 volar plate avulsion fractures of the fingers that were treated by excision or internal fixation and discuss the factors affecting the operative techniques and results. Fourteen cases were divided into two groups: the volar plate avulsions with excision (eight cases) and the volar plate avulsions with fixation (six). We compared clinical factors between fracture groups and between fixation methods. Fractures treated with fixation had the larger fragment, a shorter preoperative period, and the larger articular surface involvement than fractures treated with excision. Postoperative pain, average age, patients' satisfaction measured by VAS, DASH scores, grip, and pinch strength were not different between two groups. All fixated fractures healed and the time to union did not differ based on fixation method. The true size of the fracture fragment was larger than expected based on the X-ray and the fragments were usually rotated by pull of the volar plate or ligament. The size and shape of the avulsed fragment might be important factors to determine the treatment method, but the results after operation were not significantly different whether the fragment was excised or fixed.
