Surgical reconstruction for calcaneonavicular coalition. Evaluation of function and gait

The function of nineteen patients was evaluated at three to fourteen years after reconstructive surgery for calcaneonavicular coalition. Measurements of subtalar motion, single-limb functional tests, and gait analyses were carried out to determine how function in these patients differed from normal. Better function correlated well with better postoperative subtalar motion. Patients with a unilateral coalition who had good subtalar motion after resection showed symmetrical gait patterns during tests of function of the subtalar joint under conditions of stress.
