[Posterior dislocation of the talus]

This report presents a rare case of an open total talar extrusion. The patient was treated by reduction and transarticular Kirschner-wire fixation of the talus, suture of an associated Achilles tendon rupture and plaster cast immobilisation. The plaster cast and Kirschner wires were removed after 6 weeks. At 10 weeks after injury, the patient started to walk with full weight-bearing of the operated extremity. At 18 months after injury, the patient was free from subjective complaints, with persisting slight restriction of ankle dorsiflexion range of motion and recurrent perimalleolar oedema. Neither MRI nor radiographic examination showed any avascular necrosis of the talus. The authors discuss the aetiology, diagnosis, therapeutic options and the most serious complications of this injury.
