Different methods and devices are used to perform lengthening and deformity reconstruction in the tibia. Recently, the Taylor spatial frame (TSF) has been introduced as a computer-assisted and versatile external ring fixator. Lengthening index (LI) and complications are important result parameters, and the aim of this study was to review our first 20 tibial segments operated with the TSF and to compare the results with our experience of using the traditional Ilizarov external fixator (IEF).
We lengthened 20 tibial segments in 20 patients with the TSF. The results were compared with those of 27 tibial segments from 27 patients that were lengthened with the IEF. All segments were operated on with monofocal osteotomies.
In the overlapping zone of comparable lengthening distances between 2.4 and 6.0 cm, the LI of 2.4 and 1.8 months/cm was not significantly different between the TSF and IEF groups, respectively (p = 0.17). This non-significant difference was confirmed after adjustment for age.
We found no difference between the TSF and IEF frames regarding LI and complication rate. However, rotational, translational, and residual deformity correction is easier to perform with the TSF.
在胫骨延长及畸形重建中会使用不同的方法和器械。最近，泰勒空间框架（TSF）作为一种计算机辅助的多功能外固定环被引入。延长指数（LI）和并发症是重要的结果参数，本研究的目的是回顾我们最初使用TSF治疗的20例胫骨节段，并将结果与我们使用传统伊里扎洛夫外固定器（IEF）的经验进行比较。
我们使用TSF对20例患者的20个胫骨节段进行了延长。将结果与27例使用IEF延长的27个胫骨节段的结果进行比较。所有节段均采用单焦点截骨术进行手术。
在2.4至6.0 cm的可比延长距离重叠区域，TSF组和IEF组的LI分别为2.4和1.8个月/cm，差异无统计学意义（p = 0.17）。调整年龄后，这一差异无统计学意义得到了证实。
我们发现TSF和IEF框架在LI和并发症发生率方面没有差异。然而，使用TSF进行旋转、平移和残余畸形矫正更容易。
