摘要

Purpose

Medializing displacement calcaneal osteotomies are part of conservative surgical treatments and represent a reliable option in valgus flatfoot deformities. Favorable short-term results of this procedure is well-known. However, there are few series with follow-up beyond five years. This study reports the clinical outcomes of calcaneal medialization osteotomy with a minimum follow-up of five years. The primary objective was to compare functional scores and radiographic measurements at the preoperative stage, immediately post operative, and at the final follow-up.

Materials and methods

This was a retrospective, single-centre, multi-operator study of 32 patients, who underwent a medialization calcaneal osteotomy for type II flatfoot. Clinical evaluation of the patients was conducted using the American Orthopaedic Foot and Ankle Surgery (AOFAS) score and the European Foot and Ankle Society (EFAS) score. Radiographic evaluation used the plantar arch angle angle, the talus–first metatarsal axis (T-M1) on lateral weight-bearing radiographs, and calcaneal valgus on Meary’s angle in a hindfoot alignment view.

Results

Mean follow-up was seven years. AOFAS score improved from 46 to 87 and EFAS score from 11 to 20 (p < 0.05). Each radiographic parameter was significantly modified between the preoperative and immediate postoperative periods.

Conclusion

We observed a significant and lasting improvement in functional scores at a mean follow-up of seven years. The correction of the evaluated radiographic parameters was significant and remained stable over time.
