Open total dislocation of the talus with extrusion (missing talus): report of two cases.

Author information

Department of Orthopaedic Surgery, Showa University, Tokyo, Japan.


Two different methods of treatment for open dislocation of the extruded talus without soft tissue attachments (missing talus) were examined. In case 1, a 20-year-old man sustained an open total dislocation of the talus due to a motorcycle accident. The missing talus was found within 3 hr and replaced after thorough washing and debridement. Weightbearing was permitted at 20 weeks; however, the density of the talar body increased in the x-ray and nonweightbearing status was resumed. Reexamination at 2 1/2 years revealed that there was joint space narrowing on the x-ray and decreased pain with ambulation; the patient had returned to his job. In case 2, a 26-year-old man sustained an open total dislocation of the talus with a severe crush wound and impaired circulation to the foot. After thorough washing and debridement of the wound, the calcaneus and distal end of the tibia were aligned. The missing talus was found 3 days later, but not replaced. Weightbearing was allowed on the affected foot at 2 months; however, the patient felt pain at the joint surfaces and arthrodesis was consequently performed. At 2 1/2 years, the patient had a 4.0-cm leg length discrepancy in the involved extremity, but felt no pain when walking. Although reduction of the talus is ideal to preserve function and length of the extremity, several complications can occur. A review of literature on open total dislocation of the talus with extrusion was performed.
