Abstract

PURPOSE OF REVIEW: Tarsal coalitions may cause painful pes planovalgus and recurrent sprains, and can lead to arthrosis if improperly managed. In this review, we discuss the current topics related to talocalcaneal and calcaneonavicular coalitions.
RECENT FINDINGS: Tarsal coalitions are initially managed with conservative therapy, and when this approach fails, surgery is performed. Treatment of calcaneonavicular coalitions involves resection of the coalition and interposition of the extensor digitorum brevis muscle or fat, and in cases of marked valgus deformity, correction of the deformity. In talocalcaneal coalitions, recommendations include coalition resection for those affecting less than 50% of the area of the posterior facet and with a less than 16° valgus, coalition resection and valgus correction for those affecting less than 50% of the area and valgus greater than 16°, and isolated valgus correction for those affecting more than 50% of the area and with a more than or less than 16° valgus. Arthrodesis is reserved as a salvage procedure.
SUMMARY: Talocalcaneal and calcaneonavicular coalitions can cause painful pes planovalgus. Their diagnoses are confirmed by plain radiograph, computed tomography, and, in cases of fibrous or cartilaginous coalitions, MRI. Initial treatment is conservative, and when symptoms persist, resection of the coalition is recommended along with tissue graft interposition with or without associated valgus correction. Arthrodesis is indicated as a salvage procedure whenever treatment fails or with advanced arthrosis.
