Comparative Analysis of Trans-syndesmotic Versus Non-syndesmotic Screw Fixation in Surgical Treatment of Ankle Fracture with Diastasis / 대한정형외과학회잡지

ABSTRACT

Fibular fractures that begin proximal to the tibial plafond are assumed to include an injury of the syndesmosis. Many surgeons have treated this injuries by rigidly repairing the medial and lateral malleoli with trans-syndesmotic fixation. However, recently, some demonstrated that a trans-syndesmotic screw places biomechanical restrictions on the tibiotalar joint and is not required to maintain the integrity of the distal tibiofibular joint in cadava models. Thirty eight patients of ankle fracture with syndesmotic injury treated at Sun General Hospital from January 1989 to June 1994 week analyzed in clinical and radiologic aspect. The results obtained from this study were as followings. 1. If rigid anatomic medial and lateral joint fixation was obtained, syndesmotic screw fixation was not required to maintain the integrity of the syndesmotic. 2. Repairting the deltoid ligament did not enhance treatment results when fibular fracture and syndesmotic had been fixed anatomically. Therefore, we believe that syndesmotic screw fixation was indicated only when medial and lateral stabilization could not be achieved adequately.
