胫骨结节-股骨滑车间距离的 CT 测量与分析

目的：通过膝关节CT检查，完善国内青少年健康人群胫骨结节-股骨滑车间距离的相关数据，为髌骨不稳疾病的诊疗和国人胫骨结节移位手术提供参考。方法于2013年8-10月招募16∽25岁青少年志愿者65名（共计130例膝关节），行膝关节C T检查，对一般资料、体格检查及C T检查数据进行汇总分析。结果65名健康志愿者TT-TG值为（156．0±38．1） mm ，左、右侧膝关节TT-TG值比较差异有统计学意义（P ＜0.001）。男、女性受试者TT-TG值比较差异无统计学意义。不同年龄组受试者膝关节 TT-TG值比较差异无统计学意义。不同体质指数受试者膝关节 TT-TG值比较差异无统计学意义（P ＞0.05）。结论通过CT测量胫骨结节-股骨滑车间距离是较为准确和可靠的测量方法，初步建立了国人胫骨结节-股骨滑车间距离的相关参数值。

Computerized tomographic assessment of the distance between tibial tuberosity-trochlear groove

Objective To provide the anatomic parameters and CT data of adolescents about knee joints for the tibial tuberosity-trochlear groove distance and provide reference for diagnoses and treatment of patellar instability and operation of tibial tubercle shift in Chinese .Methods Volunteers of 16 to 25 years old were recruited to do a check of CT on knees in August 2013 to October 2013 ,and the data were analyzed .Re-sults Sixty-five healthy volunteers （20 males ,45 females） were recruited .In the 130 knees the normal TT-TG distance is （15 6.0 ± 3 8.1） mm ,（16 9.1 ± 3 6.6） mm in the right knee ,and （14 2.9 ± 3 5.2） mm in the left knee .There is significant difference between right and left knee （P 〈0.001） .There is no significant difference between males and females ,no significant difference between different ages and no significant difference between different BMI （P 〉0.05） .Conclusion CT is a reliable method of measurement for the TT-TG .This study preliminarily established TT-TG parameter values in Chinese .
