Complete dislocation of the talus: a case report using intraoperative 3D fluoroscopy.

Introduction: In a complete dislocation of the talus, the talus is stripped of all its ligament connections in the triple articulated ankle joint. This case report describes the treatment and the 3-year follow-up of a complete dislocation of the talus with the use of intraoperative 3D imaging.

Patients And Methods: The 19-year-old patient was involved as a driver in a car accident. After the radiological diagnosis of a complete talus dislocation, an emergency operation was performed due to the critical soft tissue condition. The ISO-C3D fluoroscope from the company Siemens (Erlangen, Germany) was utilized for reduction control.

Results: Follow-up evaluations were completed three years after the treatment, the patient had no complaints.

Discussion: Since these types of serious injuries are always combined with severe soft tissue damage, the main goals of this treatment have to be debridement and minimized iatrogenic surgical damage. By using intraoperative 3D imaging, immediate reduction control is available, so that revision operations can be avoided.

Conclusion: Complete dislocation of the talus is an extremely rare injury, which may cause serious complications. A fast and careful reduction, whether open or closed, should be the goal of treatment. Successful reduction can be determined intraoperatively with the use of 3D imaging.
