胫骨骨折内固定术后扭转角的CT测定

CT measurement of tibial torsion after internal fixation in patients suffering from unilateral tibial fracture

目的:探讨胫骨骨折内固定术后扭转角的CT测定方法及其临床价值。方法:回顾性分析27例单侧胫骨骨折内固定术后的CT资料,并与X线片资料进行对比。结果:所有病例均通过CT技术测得相应的扭转角值,X线片无法进行准确测量;26例胫骨骨折内固定术后扭转角与正常人比较无显著差异,1例达68°,提示存在扭转畸形。结论:CT对胫骨骨折内固定术后扭转角的测定比较方便、精确,具有较重要的临床应用价值。

Objective: To study the CT technique for measurement of tibial torsion after internal fixation in patients suffering from unilateral tibial fracture. Methods: CT data of 27 patients suffering from unilateral tibial fracture and receiving internal fixation were analyzed retrospectively and compared with X-ray data. Results: Tibial torsions of 27 patients were successfully obtained with CT and they could not be accurately measured with X-ray. The tibial torsions in 26 patients showed no difference with those of the normal people, with 1 in 26 patients reaching 68°, indicating the presence of tibial torsional deformity. Conclusion: CT is convenient and precise in measuring the tibial torsion of patients suffering from unilateral tibial fracture and receiving internal fixation, and it is of great clinical significance.
