Abstract:
PURPOSE: We evaluate the results of subtalar arthroereisis with Kalix(R) implant (Newdeal, Lyon, France) that were performed in painful flatfoot deformity. MATERIALS AND METHODS: We performed the subtalar arthroereisis on 16 feet of children symptomatic flexible flat feet after more than 6 months of conservative treatment. Average age was 11 years (8-14 years) old. We checked the functional status with AOFAS functional score in 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-1st metatarsal angle, calcaneal pitch angle, cuboid-surface height. Finally, we asked to patient's parents for satisfaction of the surgery. RESULTS: Mean follow up period was 34.1 months. Average AOFAS score improved from preoperatively 71.9 to postoperatively 91.3. Only one patient has subtalar pain. Average lateral 1st metatarsal angle reduced from -18.2 degrees preoperatively to -4.6 degrees at final follow-up. Average anterior to posterior 1st metatarsal angle was reduced from 18.9 degrees preoperatively to 6.5 degrees at final follow-up. Average calcaneal pitch angle was increased from 8.6 degrees preoperatively to 12.6 degrees at final follow-up. Average cuoboid-surface height was improved from 12.1 mm preoperatively to 16.0 mm at final follow-up. All patients had excellent or good satisfaction. CONCLUSIONS: Subtalar arthroereisis with Kalix(R) implant is a viable surgical alternative for painful flatfoot deformity of children.
