Realignment Midfoot Osteotomy: A Preoperative Planning Method and Intraoperative Surgical Technique.

Abstract

Deformities of the midfoot are often treated with midfoot osteotomies. The goal of the midfoot osteotomy is to create a plantigrade forefoot to hindfoot relationship. Many different techniques are described for performing midfoot osteotomies. Our goal is to present an objective pre-operative planning method and an intra-operative technique for accurate multiplanar realignment and discuss our short-term results. We retrospectively reviewed 18 patients, 10 female (56%) and 8 male (44%), that underwent realignment midfoot osteotomies. The mean follow-up was 25 months (range, 4-120). The mean age at the time of surgery was 53 years (range, 21-76). Statistically significant improvement in radiographic alignment was found in the anteroposterior talo-first metatarsal angle (p = .002) and the mechanical axis deviation of the foot (p = .02). This study proved that our pre-operative and intra-operative planning technique provides accurate multiplanar radiographic realignment with good clinical results.
