Abstract

Tarsal coalitions often present in young adults as a painful pes planovalgus hindfoot deformity. Resection of moderate and even large coalitions has become accepted as an alternative to arthrodesis. A review of the literature, however, suggests that coalitions with severe preoperative planovalgus malposition treated with resection are associated with continued disability and deformity. The authors believe that malposition contributes to persistent pain and disability after simple coalition resection. The hypothesis is that resection of the coalition with simultaneous hindfoot reconstruction can improve clinical and radiographic outcomes. Seven consecutively treated patients (eight feet) were retrospectively reviewed from the senior author's practice. Clinical exam, American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scores, and radiographic measurements were evaluated after talocalcaneal coalition resection with simultaneous hindfoot reconstruction. All patients were satisfied and would have the same procedure again. All patients were either active students or gainfully employed at last follow-up. Clinical and radiographic hindfoot alignment was corrected reliably. The average increase in medial longitudinal arch height was 8.7 mm. After 2 years the average AOFAS hindfoot score was 88. Most patients had only mildly progressive arthrosis. There were two postoperative complications that resolved (superficial wound breakdown and calf deep vein thrombosis). This hindfoot reconstruction with coalition resection increased motion, reliably corrected malalignment, and improved pain. The authors believe that coalition resection and concomitant hindfoot reconstruction is a better option than resection alone or hindfoot fusion in patients with talocalcaneal coalition and painful pes planovalgus hindfoot deformity. Triple arthrodesis should be reserved as a salvage procedure.
