| Abstract: | Seventy-six consecutive patients with 106 bunions were examined 6 years after chevron osteotomy. The feet were evaluated clinically and radiologically. The American Orthopaedic Foot and Ankle Society (AOFAS) scale (0–100) was used. The mean age of the patients was 46 years at time of operation. Ninety-six % of the operated patients were female. At 6 year follow-up, the hallux valgus angle was 17,9 degrees (range, 2–42 degrees) and the intermetatarsal angle was 10,5 degrees (range, 4–20 degrees). The change of the hallux valgus angle (compared to the preoperative X-ray picture) was 6,4 degrees (P<0,001, 95% confidence interval 4,0 to 8,7 degrees). The mean AOFAS score was 81 (±SD15). The study indicates that the long term results of chevron osteotomy are variable. The clinical evidence of effectiveness is still weak and there is an obvious need for randomized controlled trials in this field. |
