title: Operative treatment of flatfoot with talocalcaneal coalition.
abstract: Rigid flatfoot or peroneal spastic flatfoot often is associated with a congenital fibrous, cartilaginous, or osseous union of two tarsal bones or more, potentially causing great difficulties in its treatment. Since 1996, 12 patients (14 feet) with painful flatfoot and restricted motion of the hindfoot attributable to talocalcaneal coalition, were treated by resection of the coalition and subtalar arthroereisis by a bioreabsorbable implant. The results were evaluated by the ankle hindfoot clinical rating system of the American Orthopaedic Foot and Ankle Society. These clinical results also were evaluated statistically. Radiographs and computed tomography scans were taken preoperatively and postoperatively. Eight (57.1% of patients) had excellent results, three (21.4% of patients) had good results, and three (21.4% of patients) had fair results. No poor results, or subjective or objective complications were reported. On the basis of these early results, arthroereisis by implanting a bioreabsorbable device after removal of the tarsal coalition, seems to be an effective procedure for the treatment of symptomatic flatfoot associated with talocalcaneal coalitions: correcting the relationship between talus and calcaneus, restoring the alignment of the hindfoot, and reducing pain.
