Abstract:

Objective  To explore the feasibility of treatment of flatfoot without posterior tibial tendon disfunction by subtalar arthroereisis and evaluate the therapeutic effect. Methods  Data of 28 patients (40 feet) with flatfoot without posterior tibial tendon disfunction who underwent subtalar arthroereisis were retrospectively analyzed. Changes of hind foot valgus angle and talar-first metatarsal angles on lateral films before and after surgery were measured and analyzed. Changes of foot function before and after surgery were compared by American Orthopedic Foot and Ankle Society-Ankle Hindfoot (AOFAS-AH) Scale. Results  All 28 patients were followed up for 14-48 months. All indexes improved significantly. Only one patient underwent calcaneal osteotomy due to poor alignment of hind foot. Other patients did not undergo second surgery. Conclusion  Subtalar arthroereisis is an effective treatment for flatfoot without posterior tibial tendon disfunction. It is simple and minimal invasive and can relieve pain and realign foot with fewer complications.
