Objective To assess the outcome of inverted V-shaped valgus osteotomy as a treatment for congenital coxa vara in children. Methods Between Feb. 1990 and Jan. 2000,27 patients (35 hips) with congenital coxa vara underwent inverted V-shpaed valgus osteotomy. There were 16 males and 11 females. The average age was 7. 8 years (range:3 to 14 years). They all presented with limp or concomitant pain in the older children. The clinical result was evaluated according to Shi’s criteria. The X-ray films of preoperative, postoperative and the most recent follow-up periods were analyzed. Results Twenty-two patients (28 hips) were followed-up for a mean of 5. 4 years (14 months to 9 years). According to Shi’ s criteria, the excellent and good results accounted for 82. 1 % of cases. The preoperative NS angle, HE angle and ATD value were 94.5° ±9.1° ,67.2° ± 1.8° and - 3.8 mm ± 6. 9 mm respectively whereas those of the immediate postoperative were 148.0° ± 6.5°, 28.6° ± 4.3° and 27.5 mm ± 3. 1 mm; and
