Nail hooks and elastic bands external dynamic traction for fractures of the proximal interphalangeal joint

Intra-articular fractures of the proximal interphalangeal joint remain a treatment challenge for hand specialists. The purpose of this investigation was to review the results of 12 patients, 6 men and 6 women (average age, 21 y), who were treated using the nail hooks and elastic bands external dynamic traction technique for their intra-articular proximal interphalangeal joint fractures. Of the total 12 fractures, 6 involved the proximal phalanx and 6 involved the middle phalanx. The final arc of motion at the proximal interphalangeal joint averaged 89 degrees (range, 25 to 111 degrees). At the conclusion of treatment: 1 patient developed a radial deviation and 1 developed a slight ulnar deviation. All patients were able to return to their preinjury level of functioning. Nail hooks and elastic bands external dynamic traction provides an effective treatment for intra-articular proximal interphalangeal joint fractures. It is an inexpensive, easily applied, nonoperative method of treatment.
