Osteotomy is the well-established treatment of Blount's disease (tibia vara), although the types of fixation used vary considerably. The use of dynamic axial external fixation to stabilize osteotomies for tibia vara until solid union occurs without the use of supplemental casting has not been reported by other authors. From 1985 until the present, we have used osteotomy with dynamic axial external fixation as treatment of 31 tibiae in 23 patients. All osteotomies healed and there was no postoperative loss of correction. There was an average correction of 20 degrees between the pre- and postoperative mechanical axis. Advantages of dynamic axial external fixation include ease of application, adjustability, early weight bearing, the ability to lengthen the extremity, and no second operation for removal of hardware. Based on our results, we believe that dynamic axial external fixation is an excellent form of osteotomy stabilization in the surgical treatment of tibia vara.
截骨术是治疗布朗特氏病（胫骨内翻）的成熟方法，尽管所使用的固定类型差异很大。其他作者尚未报道使用动态轴向外固定来稳定胫骨内翻截骨术直至牢固愈合而不使用辅助石膏固定的情况。从1985年至今，我们采用截骨术结合动态轴向外固定治疗了23例患者的31条胫骨。所有截骨均愈合，术后无矫正丢失。术前和术后机械轴平均矫正20度。动态轴向外固定的优点包括应用简便、可调节、早期负重、能够延长肢体以及无需二次手术取出内固定。基于我们的结果，我们认为动态轴向外固定是胫骨内翻手术治疗中截骨稳定的一种极佳形式。
