We retrospectively reviewed the results of 32 patients (38 feet), with hallux valgus angles between 35 degrees and 60 degrees, who were treated by standard distal chevron osteotomy and intra-articular lateral soft tissue release. The average follow-up period was 5.2 years (4-7 years). The preoperative intermetatarsal angle averaged 14.4 degrees, and the postoperative angle averaged 7.7 degrees. The preoperative hallux valgus angle averaged 42.7 degrees, and the postoperative angle averaged 18.8 degrees. Subjectively, the satisfaction rate in terms of symptom improvement, cosmetic appearance and function was over 90%. Avascular necrosis of the first metatarsal head was not found in our series, which indicated that additional lateral soft tissue release is not contraindicated in combination with chevron osteotomy. Based on the level of satisfaction in our series, we conclude that the combination of distal chevron osteotomy and intraarticular lateral soft tissue release has broader application than the chevron osteotomy alone for patients with hallux valgus deformity.
我们回顾性分析了32例（38足）拇外翻角度在35度至60度之间、接受标准远端V形截骨术及关节内外侧软组织松解术治疗患者的结果。平均随访时间为5.2年（4至7年）。术前第1、2跖骨间角平均为14.4度，术后平均为7.7度。术前拇外翻角度平均为42.7度，术后平均为18.8度。主观上，在症状改善、外观及功能方面的满意率超过90%。我们的研究系列中未发现第1跖骨头缺血性坏死，这表明V形截骨术联合外侧软组织松解并无禁忌。基于我们研究系列中的满意度，我们得出结论，对于拇外翻畸形患者，远端V形截骨术与关节内外侧软组织松解术联合应用较单独的V形截骨术具有更广泛的适用性。
