A total of 67 patients with 94 resistant club feet were treated operatively as soon after birth as all other postnatal problems could be excluded, the mean age of the patients being 12 days. No treatment was attempted before operation. The results, after a follow-up period of a minimum of two years (mean 4.4 years) are comparable with the best published results. This method of treatment has many advantages but cannot be recommended for general use without reservations.
共有67例患者，94只患马蹄内翻足，在排除所有其他产后问题后，于出生后尽快接受手术治疗，患者平均年龄为12天。术前未尝试任何治疗。经过至少两年（平均4.4年）的随访，结果与已发表的最佳结果相当。这种治疗方法有很多优点，但不能毫无保留地推荐广泛使用。
