[Equinovarus of the foot in adults treated with tibiocalcaneal arthrodesis. Review of 18 cases].
The authors have retrospectively studied 18 cases of tibiocalcaneal arthrodesis performed to treat a fixed equinovarus deformity of the foot in 13 adult patients. The operations were performed between 1981 and 1998; there were 9 neurologic and 9 post-traumatic deformities. The mean calcaneal varus deformity was 50 degrees and the mean equinus deformity was 75 degrees. The results were evaluated using Kitaoka's criteria. We noted one postoperative cutaneous necrosis, two nonunions, one of which was reoperated by bone freshening and osteotomy of the midfoot. All rearfeet were in neutral alignment and were stable. Shortening was on average 2.8 cm. Plantar support was achieved in 10 feet, with improved autonomy, walking capacity and footwear. Overall, there were 10 good, 2 fair and 1 poor result. In the group with neurologic deformities there were 4 good, 1 fair and 1 poor result. In the group with post-traumatic deformities, there were 6 good and one fair results. Other series published also showed satisfactory results comparable to or better than those obtained with triple arthrodesis, which generates severe stiffness of the rear- and midfoot, disturbing gait. Fixed equinovarus deformity of the foot in the adult is a good indication for tibiocalcaneal arthrodesis, allowing in the majority of cases to achieve stable and painless plantar support.
