ABSTRACT
PURPOSE: To analyse the result and examine the effectiveness of the operative method. MATERIALS AND METHODS: The authors reviewed 55 osteotomies performed from February 1989 to January 1997. They performed closed-wedge osteotomy by using 2 K-wires and "figure 8"wire loop to correct the cubitus varus deformity. The follow-up period was 22 months in average (5-63 months). RESULT: The mean carrying angle, which was 25 degrees of varus preoperatively, was converted into 6.5 degrees of valgus immediate postoperatively and decreased to 4.6 degrees of valgus at the final follow-up. In range of motion of the elbow, all cases showed full range of motion except one. The mean duration of plaster-cast immobilization after the operation was 2.5 weeks. Fifty-two cases (95%) showed excellent or good results by using the Oppenheim and Bellemore evaluation method. CONCLUSIONS: Closed-wedge osteotomy through lateral approach and fixation by 2 K-wires with "figure 8" wire loop is a safe and satisfactory method having short operating time, stable internal fixation and short immobilization period.
