Adolescent tibia vara is a multiplanar deformity that can lead to progressive deformity, altered gait, unequal leg lengths, and premature knee arthritis if uncorrected. The purpose of the current study is to report our experience in management of adolescent tibia vara using Taylor Spatial Frame (TSF).
A prospective study of eleven adolescent tibia vara patients managed by proximal tibial osteotomy gradual deformity correction using TSF.
The average time in the frame was 123.5 (±25.5) days. At final follow up (average 15 (±2) months), the mean post-operative mPTA was 87 (±4) degrees (range 81 to 93 degrees), where the mean preoperative mean mPTA was 68 (±9) degrees (range 49 to 77 degrees) (p value 0.003). The mean postoperative MAD was 12.2(±11.4) mm, range (-1 to 26 mm), where preoperative mean MAD was 75.7(±14.7 mm), range (60 to 107mm) (p value 0.003). The mean postoperative PPTA was 80(±2) degrees, range (77 to 83 degrees), while the preoperative mean PPTA was 72 (±12) degrees, range (42 to 82 degrees) (p value 0.028).
Although we have not directly compared the TSF with the Ilizarov fixator, this series serves to highlight the versatility and effectiveness of the TSF in the treatment of complex and often obstinate adolescent tibia vara.
青少年胫骨内翻是一种多平面畸形，如果不加以矫正，可导致畸形进展、步态改变、腿长不等以及过早出现膝关节炎。本研究的目的是报告我们使用泰勒空间框架（TSF）治疗青少年胫骨内翻的经验。
对11例采用TSF进行胫骨近端截骨逐渐矫正畸形的青少年胫骨内翻患者进行前瞻性研究。
使用框架的平均时间为123.5（±25.5）天。在末次随访时（平均15（±2）个月），术后平均机械轴胫骨角（mPTA）为87（±4）度（范围81至93度），术前平均mPTA为68（±9）度（范围49至77度）（p值0.003）。术后平均机械轴偏移（MAD）为12.2（±11.4）mm，范围（-1至26mm），术前平均MAD为75.7（±14.7mm），范围（60至107mm）（p值0.003）。术后平均近端胫骨干角（PPTA）为80（±2）度，范围（77至83度），术前平均PPTA为72（±12）度，范围（42至82度）（p值0.028）。
虽然我们没有将TSF与伊里扎洛夫固定器进行直接比较，但本系列研究突出了TSF在治疗复杂且往往顽固的青少年胫骨内翻方面的多功能性和有效性。
