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.
