Varisation osteotomies on the distal femur are an established treatment method for valgus osteoarthritis of the knee in younger patients. Osteotomy can be done in a lateral open-wedge or medial closed-wedge manner.
We retrospectively studied 14 patients treated by the lateral open-wedge technique, fixed with the Tomofix plate, with a mean duration of follow-up of 45 ± 3.4 months.
We observed often delayed osteotomy healing after 3, 6 and 12 months, no secondary dislocations, and frequent troublesome irritation due to the plate being on the iliotibial band. However, outcome was satisfactory once the osteotomy healed and the plate was removed.
Based on the often slow healing of the osteotomy and frequent irritation due to the plate, this procedure has been abandoned by the authors, and the medial closing-wedge osteotomy adopted as the alternative treatment.
对于年轻患者的膝关节外翻性骨关节炎，股骨远端的截骨术是一种成熟的治疗方法。截骨术可以采用外侧开放式楔形或内侧闭合式楔形的方式进行。
我们回顾性研究了 14 例采用外侧开放式楔形技术治疗的患者，使用 Tomofix 板固定，平均随访时间为 45 ± 3.4 个月。
我们观察到术后 3、6 和 12 个月时经常出现延迟的截骨愈合，没有二次脱位，但由于钢板位于髂胫束上，经常出现烦人的刺激。然而，一旦截骨愈合并取出钢板，结果是令人满意的。
基于截骨愈合缓慢以及钢板经常引起刺激，作者已放弃该手术，转而采用内侧闭合楔形截骨术作为替代治疗方法。
