Abstract

Aim: Extraosseous talotarsal stabilization (EOTTS) is increasingly popular as a surgical treatment for adult symptomatic flexible pes planus. This can be performed alone or combined with medializing calcaneal osteotomies with or without medial column stabilization. The aim of our radiographic study is to evaluate the changes in various radiographic parameters of a pes planus deformity including hindfoot alignment after EOTTS. We hypothesize that EOTTS can demonstrate improvement in radiographic parameters, including hindfoot alignment. Materials and methods: A total of 12 feet from nine patients who had undergone EOTTS using the HyProCure implant were analyzed. Weight-bearing radiographs were used to measure the pre- and postoperative talar-second metatarsal, lateral Meary's, calcaneal inclination, talar declination angles. Hindfoot alignment was measured using fibular axis calcaneal offset (FACO) method. Results: Our results showed significant improvement in all the radiographic parameters including hindfoot alignment. Conclusion: There is a radiographic improvement in a flexible pes planus deformity after an EOTTS procedure, including hindfoot alignment. Clinical significance: Hindfoot alignment can be corrected with EOTTS procedure with or without associated procedures.
