Abstract:
PURPOSE: To determine the clinical and radiographic results of arthroereisis using the Kalix(R) implant (Newdeal, Lyon, France) for the treatment of flexible flatfoot deformity. MATERIALS AND METHODS: From February 2005 to February 2007, we performed the subtalar arthroereisis on 8 patients (9 feet) of symptomatic flexible flat feet after more than 6 months of conservative treatment. Average age was 14.5 years (11~29 years) old. We checked the functional status with AOFAS functional score pre-operatively and at final follow-up. Radiologically, we took weight bearing anterior to posterior and lateral view of the feet, and measured the talo-first metatarsal angle, calcaneal pitch angle in pre-operatively and at final follow-up. RESULTS: Mean follow up period was 34.4 months. Average AOFAS score improved from preoperatively 65.6 to postoperatively 94.8. Average lateral talo-first metatarsal angle reduced from 12.8degrees preoperatively to 1.6degrees at final follow-up. Average anterior to posterior talo-first metatarsal angle was reduced from 15.1degrees preoperatively to 8.3degrees at final follow-up. Average calcaneal pitch angle was increased from 9.5degrees preoperatively to 12.0degrees at final follow-up. CONCLUSIONS: Subtalar arthroereisis with Kalix(R) implant can be considered to be one of treatment options symptomatic flatfoot deformity patients.
