Abstract

Total extrusion of the talus with interruption of all ligaments (missing talus) is a rare injury. We describe the case of a 27-year-old man who reported total extrusion of the talus after a motorbike accident with interruption of all talar ligaments. In the first repair effort, the articular void left by the talus was filled with antibiotic cement and the wound was closed primarily. Nevertheless, the skin overlying the talar joint displayed necrosis. In order to cover the cutaneous defect, improve local vascularization, and allow reimplantation of the talus, a sural fasciocutaneous island flap was harvested. Subsequently, the original talus was placed and arthrodesis of the subtalar joint was performed. The patient was able to walk bearing full weight without support equipment after 6 months. Several therapeutic options have been suggested in such cases, including replacing the talus, tibiocalcaneal arthrodesis, and pseudoarthrodesis. The rarity and peculiarity of such cases make the establishment of generalized guidelines an arduous task, leaving the choice of treatment to the surgeon, in conformity with each case's peculiarity. In this case use of the flap may have promoted the vascularization of the reimplanted talus, thus avoiding avascular necrosis and allowing successful reimplantation of the original talus.
