Arthrodesis of the subtalar joint, triple arthrodesis (involving the subtalar, talonavicular, and calcaneocuboid joints), double arthrodesis (involving the talonavicular and calcaneocuboid joints), arthrodesis of the talonavicular joint, and arthrodesis of the calcaneocuboid joint were simulated in a cadaver model, and the range of motion of each joint not involved in the simulated arthrodesis was measured with a three-dimensional magnetic space tracking system. The excursion of the posterior tibial tendon was also measured under all of these conditions...

BACKGROUND: Surgical resection of persistently painful talocalcaneal tarsal coalitions may not reliably relieve symptoms in patients with large coalitions associated with excessive hindfoot valgus deformity and subtalar posterior facet narrowing. Since 1991, calcaneal lengthening osteotomy, with or without coalition resection, has been used at our institution to relieve symptoms and to preserve motion at the talonavicular and calcaneocuboid joints. METHODS: We retrospectively reviewed the records for eight patients with thirteen painful talocalcaneal tarsal coalitions who had undergone a calcaneal lengthening osteotomy for deformity correction with or without coalition resection between 1991 and 2005...

BACKGROUND: Treatment of spastic planovalgus feet is challenging, especially in patients with severe and rigid deformities. The available techniques do provide some correction but not at the site of the deformity and sometimes the correction is lost over time. We describe a new surgical approach at the site of the deformity. TECHNIQUE: Indications for the surgery included adolescents or young adults with severe and rigid planovalgus deformities of the feet resulting from cerebral palsy...

PURPOSE: Talocalcaneal coalitions can be difficult to detect on plain radiographs, despite obvious clinical findings. The purpose of this study is two-fold: (1) to delineate the benefits of thin-cut computed tomography (CT) and 3D reconstructions and (2) to develop a classification scheme for talocalcaneal coalitions that will provide valuable information for surgical planning. METHODS: From 2005 to 2009, 54 feet (35 patients) with a talocalcaneal coalition were evaluated with thin-cut (1 mm) CT, using multi-planar 2D and 3D reconstructions...

Triple arthrodesis is indicated for pain, deformity, and instability of the tritarsal complex. Although osseous consolidation is important to outcome, success depends primarily on appropriate realignment. A poorly positioned triple arthrodesis may result in continued pain and disability, gait disturbances, excessive stress in adjacent joints, and footwear problems. We present a protocol for intraoperative realignment of the triple arthrodesis guided by image intensification. This protocol for alignment evaluation was followed in nine patients who underwent triple arthrodesis for a variety of pathologies...

Most of the clinical studies report the incidence of tarsal coalitions (TC) as less than 1% but they disregard the asymptomatic coalitions. TC have been associated with degenerative arthritic changes. After X-rays, computer tomography (CT) is the most commonly used diagnostic test in the detection of TC. The aims of our study were to establish the incidence of TC; the association between TC and accessory tarsal bones and between TC and tarsal arthritis; and to assess the sensitivity of CT as a diagnostic tool in TC...

Tarsal coalition refers to a union of two or more tarsal bones. The union may be fibrous, cartilaginous, or bony. The most common sites of tarsal coalition reported in the literature are the calcaneonavicular, the talocalcaneal, and, less commonly, the talonavicular areas. Bilateral coexistent multiple tarsal coalitions are a rare occurrence. The authors present a case report of a 17-year-old boy with bilateral coexistent calcaneonavicular and talonavicular bars. The diagnosis was established by radiographs and CT scanning...

Histopathological analysis was performed on 55 feet in 48 patients with nonosseous tarsal coalitions. Histological findings were similar to those observed at the tendinous attachment site of Osgood-Schlatter disease, accessory navicular, and bipartite patellae. No nerve elements were observed in the fibrocartilaginous tissue at the coalition. Nerve elements were present only in periosteum and articular capsule surrounding the coalition. Pain in the tarsal coalition is not mediated by nerve elements at the coalition site itself...

PURPOSE: To evaluate the usefulness of the C sign, a C-shaped line formed by the medial outline of the talar dome and the inferior outline of the sustentaculum tali, in the diagnosis of subtalar coalition (SC) on lateral radiographs of the ankle. MATERIALS AND METHODS: Lateral ankle radiographs obtained before and after the availability of computed tomography (CT) at the authors' institution were retrospectively and prospectively evaluated for the presence of the C sign...

Ball-and-socket ankle is a rare deformity associated with such pre-existing conditions as congenital shortening of the lower limb, coalition of tarsal bones, absent digital rays and aplasia or hypoplasia of the fibula. We have observed seven patients with this deformity for an average of six years from initial examination at 20 days to 3.5 years. Arthrography showed that the configuration of the ankle was apparently normal in patients under 10 months of age and that a ball-and-socket joint develops by four to five years of age, possibly in compensation for the loss of inversion and eversion caused by tarsal coalition...
