Background. The purpose of this study is to examine the relationship between foot morphologic characteristics and inversion ankle sprains. The incidence of anterior cavo-varus foot was retrospectively investigated as a possible risk factor of recurrence after injuries. Methods. Lateral ankle sprains related to sport injuries were collected in a retrospective 5-year study; 1493 patients were re-examined. The age at injury ranged from 16 to 45. Residual problems were registered within 18 months follow-up after the first sprain. All subjects were asked concerning the amount of time off after injury, the involvement in a rehabilitation program, the use of a prophylactic ankle support, the occurrence of re-injury, and residual sport-limiting symptoms. Clinic and functional assessments were focused on the examination of foot architecture. Lower leg-foot alignment and foot arch were investigated to determine the rate of cavo-varus feet. According to the method of Viladot and Coleman test, 3 progressive degrees of cavo-varus foot were identified. Anterior cavo-varus foot was identified by 2nd or 3rd degree longitudinal arch in combination with a positive test (plantar flexed 1st ray deformity). Results. The incidence rate of cavo-varus foot was 51% of the first lateral ankle ligament injuries. The same tendency toward re-injury was observed in the 1st degree cavo-varus foot and the normal foot. An interesting finding was the high correlation of anterior cavo-varus foot structure and the occurrence of re-injury (66.3%). Rehabilitation protocols and ankle stabilizers were effective to prevent further sprains. Therefore rigid cavo-varus foot structure showed significant low compliance to ankle braces. At 18 months follow-up, only 38% of the competitive subjects regained full pre-injury athletic level. Conclusions. Possible risk factors for ankle inversion re-injuries include foot structure and alignment. Our study underlines the presence of anterior cavo-varus foot as directly implicated in the occurrence of re-injuries. Proper investigation on functional anatomy of the first ray and longitudinal arch is necessary to evaluate the relationship between foot morphologic characteristics and risk of sports-related injury. Recurrent inversion sprains in presence of anterior cavo-varus may be less likely to occur if an orthosis is used.
