This paper describes a simple technique of oblique osteotomy of the first metatarsal for treatment of symptomatic hallux valgus deformity. The osteotomy is performed at a 30 degree angle from the long axis of the metatarsal shaft. The head of the metatarsal is then displaced laterally to provide correction of the hallux valgus. This is an uncomplicated procedure for the treatment of hallux valgus. From 1984 through 1989, 53 feet in 31 patients were treated with an oblique osteotomy of the first metatarsal. A total of 49 feet in 27 patients were followed up more than 2 years. The follow-up x-rays and clinical examinations revealed a good result in 43 feet. In six feet of three patients, all of whom had simultaneous oblique osteotomies of both the first and second metatarsals, a fair or poor result was obtained. It was learned that oblique osteotomy for hallux valgus greater than 40 degrees provided insufficient correction of the valgus angle or limitation of motion at the metatarsophalangeal joint of the great toe.
本文描述了一种用于治疗有症状的拇外翻畸形的第一跖骨斜行截骨术的简单技术。截骨术在与跖骨干长轴呈30度角处进行。然后将跖骨头向外侧移位以矫正拇外翻。这是一种治疗拇外翻的简单手术。从1984年到1989年，31例患者的53只脚接受了第一跖骨斜行截骨术治疗。27例患者的49只脚接受了超过2年的随访。随访的X线片和临床检查显示43只脚效果良好。在3例患者的6只脚中，所有这些患者同时进行了第一和第二跖骨的斜行截骨术，结果为一般或较差。研究发现，对于大于40度的拇外翻进行斜行截骨术，外翻角度矫正不足或拇趾跖趾关节活动受限。
