Purpose: Many skeletal traction devices have been described to treat fracture dislocations of the proximal interphalangeal (PIP) joint. Most of these techniques are technically challenging or involve cumbersome frames. We present a design modiﬁcation that enhances the stability of a simple dynamic ﬁxation system described previously and report our results with this technique.
Methods: A previously described simple dynamic ﬁxator with no rubber bands was applied to 6 patients who sustained fracture dislocations of the PIP joint. The middle ﬁnger was involved in 3 patients, the ring ﬁnger in 1 patient, and the small ﬁnger in 2 patients. The average age of the patients was 27 years (range, 21–42 y). The average involvement of the base of the middle phalanx was 48% (range, 35% to 60%). The average time from the injury to the surgery was 6 days (range, 1–14 d). The average follow-up period was 24 months (range, 7–43 mo). Immediate active ﬂexion extension was allowed and the ﬁxator was removed after 3 to 4 weeks.
Results: The average range of motion of the PIP joint at the ﬁnal follow-up evaluation was 5° to 89°(range, 0° to 100°). Two patients developed pin track infection that resolved with oral antibiotics. Only one patient complained of mild pain with extreme ﬂexion. Proper reduction and congruency of the joint was noted on ﬁnal anteroposterior and lateral radiographs.
Conclusions: A simple dynamic ﬁxator for the treatment of unstable PIP joint fracture dislocations was used succesfully in 6 digits to maintain reduction and restore digital range of motion. The addition of modiﬁcations to the original technique not only improves the solidity of the construct but also provides satisfactory functional results. Based on our experience we recommend this easy technique to treat fracture dislocations of the PIP joint. (J Hand Surg 2005;30A:154–160.
