Open reduction and circular external fixation of intraarticular calcaneal fractures.
Open reduction and internal fixation techniques do not allow early weight bearing. In an effort to develop a better method to obtain calcaneal fracture reduction and maintain it in the face of early weight bearing, a circular external fixator was applied to seven patients in combination with a limited lateral approach and open reduction and internal fixation of the depressed subtalar joint fragments. The operative technique uses the Ilizarov circular external fixator to obtain a ligamentotaxis reduction, following which the depressed subtalar joint fragments are elevated open; then, the fixator is used to reduce the lateral translation. All displacements of the fracture fragments are corrected. This method proved successful in six patients, all of whom achieved a satisfactory result with anatomic restoration of the subtalar joint and heel. One patient went on to late partial collapse of the posterior facet. Subtalar motion was greater than 50% in four of seven patients. None of the patients complained of heel pad pain, which was attributed to the desensitization of the heel by early weight bearing. This technique has produced encouraging preliminary results in two- to four-year follow-up evaluation.
