title: Association of ankle instability and foot deformity.
abstract: 95 patients operated on for chronic lateral ankle instability were compared for possible foot deformities with 34 normal persons. All the feet underwent a standardized radiographic examination. Measurements of three defined angles on a lateral nonweight-bearing radiograph indicated higher foot arches in the instability group than in the control group. Benink's tarsal index showed a higher frequency of cavovarus deformities in the instability group.
