[Current status of diagnosis and therapy of chronic collateral ligament instability of the ankle joint: results of a survey of 267 German clinics in 1994].
A questionnaire was mailed to the heads of 400 German orthopaedic departments listed by the "Deutsche Gesellschaft für Unfallchirurgie", with the aim of evaluating the diagnostic and therapeutic approaches to chronic ankle instability that were current in 1994. The questionnaire was structured to focus on diagnostic imaging techniques, conservative and surgical management, and postoperative treatment. Evaluable questionnaires were returned from 267 hospitals (66.7%). The number of ligament reconstructions performed per institution ranged from 1 to over 100 (mean 17.5). Radiographic stress investigations and clinical examination were considered by 71.6% of the surgeons to be the most important criteria for surgical therapy. The methods most frequently used for primary reconstruction of the ligaments were: periosteal flaps (45.3%), anatomical repair (23.6%), different tenodeses (20.6%), and free anatomical implants of autologous or exogenous material (10.5%). Half the respondents used reconstruction procedures involving secondary repair of the injured ligament without augmentation or with periosteal flaps. The other half of the German surgeons preferred tenodeses or various other procedures. Conservative management of chronic ankle instability was considered by surgeons to be less appropriate for young active patients. Postoperative treatment includes casting and orthosis. The duration varied from 2 weeks to 8 weeks. The results of the nationwide survey demonstrate that more objective clinical methods of diagnosis are needed to allow preoperative differentiation between functional and mechanical instability. With better knowledge of the function of individual ligaments and more frequent exposure of the ligaments for simple overlap and direct suture, a lower rate of primary non-anatomical reconstructions may be possible in the future.
