Purpose: The purpose of this study is to evaluate the results of Kidner procedure combined with medial displacement calcaneal osteotomy (MDCO) in patients with the symptomatic accessory navicular with hindfoot valgus. Materials and Methods: From January 2014 to January 2019, fifteen patients (15 cases) who had undergone a Kidner procedure combined with MDCO for symptomatic accessory navicular with hindfoot valgus were included. Their mean age was 36.3 years old (19~61 years old) and there were 6 males and 9 females. The clinical results were evaluated using visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, and postoperative subjective satisfaction. The radiographic results were evaluated using the talonavicular coverage angle and the anteroposterior talo-first metatarsal angle, the lateral talo-first metatarsal angle, the calcaneal pitch angle, and the hindfoot alignment angle. The postoperative complications were also evaluated. Results: The VAS and AOFAS midfoot scores continuously improved until 12 months after surgery. Subjective satisfaction after surgery was excellent in 10 cases and good in 5 cases. The hindfoot alignment angle significantly changed after surgery. Pain due to lateral impingement disappeared in five patients, and persisted in one patient. Five patients complained of irritation caused by their fixation devices, and all the symptoms improved after removal of the fixation devices. Conclusion: Kidner procedure combined with MDCO in patients with the symptomatic accessory navicular with hindfoot valgus showed good clinical results with satisfactory correction of hindfoot valgus. In particular, the clinical results showed continuous improvement until 12 months after surgery.

Purpose: To evaluate the short-term results of medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot deformity. Materials and Methods: Twenty four patients (25 feet) who had undergone medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot between July 2004 and May 2007 were included. The mean age was 43.6 years (16~78 years). The mean follow-up was 26 months (14~50 months). Clinical outcomes were assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS). Six radiographic parameters were measured from weightbearing radiographs to assess the difference between preoperative and postoperative radiographs. Results: The mean AOFAS score improved from 57.9 points preoperatively to 89.2 points at latest follow-up (p=0.000). The mean VAS improved from 62 points preoperatively to 23 points at latest follow-up (p=0.000). The mean talonavicular coverage angle on anteroposterior (AP) view changed from 20.2 degrees to 16.0 degrees (p=0.002). The mean calcaneal pitch angle on lateral view changed from 12.6 degrees preoperatively to 14.5 degrees at latest follow-up (p=0.001). Regarding these radiographic parameters, the difference between interobserver measurements was larger than that between pre- and post-operative measurements. The calcaneus was transferred medially by average 11.8 mm (p=0.003), which was 27.9% of the width of calcaneal tuberosity (p=0.000). The mean talo-first metatarsal angle on AP and lateral views, and navicular height on lateral view were not significantly changed. Conclusion: Medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot could lead to improve the clinical outcomes, although the restoration of medial longitudinal arch was not clinically significant.
