Treatment of proximal interphalangeal joint fractures by the pins and rubbers traction system: a follow-up

AbstractA fracture of the proximal interphalangeal (PIP) joint at the base of the middle phalanx is rare, but is a challenge to treat. Posttraumatic osteoarthritis is a known complication causing impaired hand function and disability. The aim of the present retrospective study was to evaluate characteristics and outcome of complex PIP joint fractures treated by the pins and rubbers traction system (PRTS). Medical records of 42 patients with fractures treated with a PRTS in 1999–2010 were reviewed, and followed-up by questionnaires (QuickDASH, CISS, self-composed questionnaire). Eighteen of the 42 were clinically examined. The fractures were divided into three types of fractures: volar lip, dorsal lip, and pilon fractures. The volar lip fracture was most frequent (26/42; dorsal lip 3/42; pilon 13/42). Most fractures were sport-related (19/42; 45%) and males predominated (M:F ratio = 1.8). All fractures united. Infection occurred in 17/41 (41%) cases. Radiological signs of posttraumatic osteoarthritis were ...
