of function and gait. Chambers-RB; Cook-TM; Cowell-HR J-Bone-Joint-Surg-Am. 1982 Jul; 64(6): 829-36 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.
