内反肘に対するInterlocking Wedge Osteotomyの術後成績

The authors reviewed 20 patients with cubitus varus deformity who were treated with the interlocking wedge osteotomy. All deformities including medial, posterior tilt and internal rotation of the distal fragment can be simultaneously corrected with this osteotomy. There were 14 males and 6 females whose average age was 5.0 years at injury and 14.1 years at surgery. The average follow-up period was 37 months. Thirteen patients had excellent results, 6 good, and 1 poor. The mean carrying angle was improved from 21.5° of varus to 8.8°of valgus, compared to 9.4°of valgus on the uninjured side. The mean flexion of the elbow increased from 123.9°to 134.3゜, and the mean hyperextension decreased from 12.0°to 7.5°. Three-dimensional correction and stable fixation can be achieved with this osteotomy.
