[Experiences with using the soft cast in injuries of the fibular ligament of the upper ankle joint]

Abstract

From June 1993 until October 1994, 75 persons with recent ruptures in the region of the fibular ligament at the ankle joint were treated with a Softcast at our hospital. The patients were divided into a surgical and a conservative group: 33 patients were operated on and 42 were treated conservatively; 49 persons were male, 26 female. Both groups were initially treated with a conventional cast, and after the first week a Softcast was used. Surgery was performed whenever X-ray examination showed a difference of more than 10 degrees in supinatory subluxation between the unstable ankle and the intact one or anterior instability of more than 10 mm. In 55 of these patients follow up by clinical and X-ray examination was possible after an average period of 14.5 months after trauma and treatment. For the clinical follow-up the 100-point Pförringer-Stolz score was used (6), and the X-ray examination was performed under constant conditions by means of these standardized conditions, excellent and good results were achieved in more than 95% of the patients. The authors recommend the semi-rigid immobilization with Softcast in both operatively and conservatively treated patients with ruptures of the lateral ankle ligaments.
