The "Z" osteotomy versus the Kalish osteotomy for the correction of hallux abducto valgus deformities: a retrospective analysis.

Abstract

A retrospective analysis of hallux abducto valgus surgery performed between 1990 and 1995 where the "Z" osteotomy and Kalish osteotomy were utilized was performed. Objective and subjective data were collected to determine the effectiveness of the Z osteotomy versus the Kalish osteotomy. Twenty cases of hallux abducto valgus where the Z osteotomy was utilized were evaluated on the basis of intermetatarsal angle correction and alleviation of preoperative symptoms. The same evaluation was performed on 21 cases where the Kalish osteotomy was utilized. There did not appear to be an appreciable difference in intermetatarsal angle correction between the two osteotomies; however, the Kalish osteotomy did alleviate preoperative symptoms to a greater degree compared with the Z osteotomy.
