The medial approach to triple arthrodesis. Indications and technique for management of rigid valgus deformities in high-risk patients.

Between 1995 and 2002 the authors treated 17 patients who had a rigid hindfoot valgus deformity, and for whom a triple arthrodesis was planned, using a single medial incision. The indication for surgery was pain that was refractory to shoe wear, orthotic, and brace modifications. The severity of the hindfoot deformity itself was not a sufficient indication for this procedure. All 17 patients were examined a mean of 3.5 years following surgery (1-8 years). Subtalar and talonavicular arthrodesis was achieved in all patients and calcaneocuboid arthrodesis was achieved in 15 of 17 patients (2 asymptomatic pseudoarthrosis). The medial approach to triple arthrodesis is a reliable procedure, and can be used with a predictable outcome in patients who are at risk for wound healing complications for correction of hindfoot valgus deformity.
