Seven years follow-up after ankle inversion trauma.

During one year all ankle inversion injuries seen at the acute ward of our institution were divided into grades of severity and classified according to the maximal area of tenderness at the time of clinical examination. Seven years later 648 of the subjects (91%) evaluated their ankle with the help of a questionnaire. Location of maximal tenderness at the time of injury was: lateral fibular ligaments 61%, lateral midfoot ligaments 24%, base of the fifth metatarsal/peroneal tendons 5% and combined lesions 8%. 39% were considered minor, 46% were moderate, and 15% severe. All cases followed a functional treatment protocol. Seven years post- injury 32% reported chronic complaints of pain, swelling or recurrent sprains. 72% of the subjects with residual disability reported that they were functionally impaired by their ankle - in most cases a question of not performing sports at a desired level. 4% experienced pain at rest and were severely disabled. 19% were bothered by repeated inversion injuries - 43% of these subjects felt that they could compensate by using an external ankle support. There was no correlation between the severity of the sprain as judged at the time of injury and the frequency of residual disability or between the area of maximal tenderness at the time of injury and the area of maximal pain at the time of follow-up.
