title: Acute midtarsal sprains: frequency and course of recovery.
abstract: In a prospective consecutive registration of 711 ankle inversion sprains, the dorsal ligaments and capsule of the midtarsal joints were involved in 237 of the cases (33%), and in 172 cases (24%) only these joints seemed to be injured. A total of 162 isolated midtarsal injuries and 161 cases of isolated lateral talocrural lesions selected at random were followed using questionnaires 1, 3, 6, 9, and 12 months after injury. The frequencies of pain after 1 month and swelling after 1 and 3 months were significantly lower in isolated dorsal midtarsal sprains compared with isolated lateral talocrural sprains. At the following controls, frequencies of both pain and swelling were the same for both groups. Functional instability appeared with the same frequency in both groups during the 12 months of follow-up. Regarding the social impact of the sprains, absence from work and sports did not differ between groups. When avulsions were present in midtarsal injuries recovery was slow, with two thirds of the patients experiencing pain after 6 months. We conclude that the dorsal midtarsal sprain is a common entity with a course of recovery and a frequency of residual symptoms very like the lateral talocrural lesions.
