Metatarsal Osteotomy for the Cavus Foot

Thirty-nine patients with pes cavus-type deformities were treated with osteotomy of the proximal metatarsals for the cavus component of the deformity. Fifty operations were followed for an average of 15 years, many for up to 26 years. Of the 39 patients, 11 had bilateral involvement. Each patient was clinically evaluated for postoperative mobility and categorized according to the Massachusetts General Hospital rating scale. Excellent or good results were obtained in 84% of the proximal metatarsal osteotomies.
