We performed basal chevron metatarsal osteotomy on 32 feet (31 patients) for painful hallux valgus associated with an increased intermetatarsal 1/2 angle (> 12 degrees). Pedobarographic and radiological examinations were done preoperatively and at a minimum of six months postoperatively. The average hallux valgus angle was improved from 40.9 degrees to 19.2 degrees and the intermetatarsal 1/2 angle from 16.5 degrees to 6.8 degrees. The mean angle of declination of the first metatarsal was decreased by 1.4 degrees. The pedobarographs showed a significant reduction in areas sustaining pressure > 5 kg/cm2, an increased total foot contact area and a higher percentage forefoot contact area on heel raise. There was a high level of patient satisfaction with relief of symptoms and improved appearance of the foot.
我们对32只足（31例患者）进行了基底V形截骨术，用于治疗与第1、2跖骨间角增大（>12度）相关的疼痛性拇外翻。术前及术后至少6个月进行了足压力分析和放射学检查。平均拇外翻角从40.9度改善至19.2度，第1、2跖骨间角从16.5度改善至6.8度。第1跖骨的平均倾斜角减小了1.4度。足压力分析显示，承受压力>5 kg/cm2的区域显著减少，全足接触面积增加，足跟抬起时前足接触面积百分比更高。患者对症状缓解和足部外观改善的满意度较高。
