Cerclage Fixation for Fracture Dislocation of the Proximal Interphalangeal Joint

Dorsal fracture dislocations of the proximal interphalangeal joint remain 1 of the most difficult problems in which to obtain an excellent functional outcome. The use of minimally invasive internal fixation techniques improving the biologic healing response and yet providing fracture fragment stabilization has met with greater popularity in recent years. The results of 12 patients treated by the volar cerclage wiring technique are described. At average followup examination of 2.1 years, 11 of 12 patients were noted to have no degenerative joint changes with only 1 patient having evidence of early volar articular surface beaking. Average final active arc of motion at the proximal interphalangeal joint was 89 ° (range, 72 °-109 °). The average degree of extension loss at the proximal interphalangeal joint was 8 ° (range, 0 °-16 °). There were no complications involving implant failure, irritation, or infection. A description of the volar cerclage wire technique is presented. This technique provides the advantage of avoiding fracture fragment stripping, stable restoration of the articular surface, and palmar buttress of the middle phalanx at the proximal interphalangeal joint.
