INTRODUCTION
The aim of the study was to study results of (made in India) hexapod external fixator (HEF) (deft fix)-assisted correction in a case of knee subluxation with malunited medial tibial condyle fracture.
METHODOLOGY
A subject with knee subluxation was selected for application of hexapod and Ilizarov ring fixator for staged correction of subluxation using deft fix-assisted correction.
RESULT
The study shows anatomical reduction of the subluxated knee using HEF with deft fix-assisted correction.
CONCLUSION
The HEF does not require frame transformation and is easier to use and is known to have the ability to correct complex multiplanar deformities better and much faster than the traditional Ilizarov ring fixator which requires multiple changes in hardware while correcting complex deformities. Software-assisted hexapod correction provides more faster and accurate correction with the ability to do fine adjustments at any stage of correction.
引言
本研究的目的是探讨（印度制造的）六足外固定器（HEF）（灵巧固定器）辅助矫正膝关节半脱位合并胫骨内侧髁骨折畸形愈合的效果。
方法
选择一名膝关节半脱位患者，应用六足外固定器和伊里扎洛夫环形固定器，采用灵巧固定器辅助矫正方法分阶段矫正半脱位。
结果
研究表明，使用HEF并采用灵巧固定器辅助矫正可使半脱位膝关节实现解剖复位。
结论
HEF无需进行框架转换，使用更简便，且已知其能够比传统伊里扎洛夫环形固定器更好、更快地矫正复杂的多平面畸形，传统固定器在矫正复杂畸形时需要多次更换硬件。软件辅助的六足外固定器矫正能够提供更快、更准确的矫正效果，并且在矫正的任何阶段都能够进行精细调整。
