Abstract
The purpose of the study was to evaluate the efficacy of subtalar arthroeresis for II stage tibial tendon dysfunction by Johnson and Storm classification. From November 2007 to August 2009, 18 patients with that pathology were operated on. After implantation of Kalix® II endorthesis the plasty of posterior tibial tendon was performed. The results were assessed by American Orthopaedic Foot and Ankle Society (AOFAS) scores system. After treatment average estimate by AOFAS increased from 47.2 before operation to 79.0 after surgery, pain index from 16.3 to 30.0, foot function from 28.7 to 41.6, foot position from 2.6 to 8.4. According to X-ray data the longitudinal arch angle decreased by 14.3° at an average and talar-calcaneal angle by 8°. Study results showed that technique of subtalar arthrodesis was effective enough for correction of flat foot resulted from II stage posterior tibial tendon dysfunction. Combination of that technique with tendon plasty ensured the full-value reconstruction of the foot.
