【摘要】：目的依据国际脊柱畸形研究组(Spine Deformity Study Group SDSG)分型方法对青年军人下腰椎峡部裂患者进行分型,并针对其矢状位参数特点进行分析。方法回顾性分析2015年3月到2016年6月我科收住的峡部裂患者的临床资料。并依据纳入排除标准对其进行筛选。依据SDSG分型方法对入选人群进行分型,分析各型斜位X线片的影像学特点。同时对侧位X线片上进行脊柱-骨盆参数的测量(包括PI、PT、SS、LL、STA、STI、SP等),并对测量结果进行组间统计学分析。结果共纳入患者72例,其中“钳夹型”17例,“剪切型”13例,“正常”42例。统计结果显示:各组间在年龄、滑脱百分比SP、骶骨平台指数STI等方面无明显差异;在LL、PT、SS和STA等方面存在着差异。“剪切型”和“钳夹型”、“正常型”相比,“剪切型”在腰椎前凸角LL、骨盆倾斜角PT、骶骨倾斜角SS等方面均大于“钳夹型”和“正常型”,而“剪切型”的骶骨平台角STA较“钳夹型”“正常型”明显偏小,且这种差异具有统计学意义。相关性检验显示PI与LL、SS呈高度正相关,与STA呈低度负相关。结论1.青年军人下腰椎峡部裂患者经SDSG分型后,“剪切型”较“正常型”、“钳夹型”具有更大的LL、PT、SS以及更小的STA;2.PI与LL、SS呈高度正相关、与STA呈低度负相关。
[Abstract]:Objective to analyze the characteristics of sagittal parameters in young servicemen with lower lumbar spondylolysis according to the (Spine Deformity Study Group SDSG) classification method of international study group of spinal deformities. Methods the clinical data of patients with isthmic fissure admitted from March 2015 to June 2016 were analyzed retrospectively. They were screened according to the exclusion criteria. According to the method of SDSG classification, the imaging characteristics of each type of oblique radiographs were analyzed. The spinal and pelvic parameters (including PI,PT,SS,LL,STA,STI,SP, etc.) were measured on lateral radiographs, and the results were analyzed statistically. Results A total of 72 cases were included, including 17 cases of "clamp type", 13 cases of "shear type" and 42 cases of "normal". The statistical results showed that there were no significant differences in age, percentage of slippage, SP, sacral plateau index (STI), but there were differences in LL,PT,SS and STA among the groups. Compared with "clamp type", "shear type" and "normal type", the "shear type" was larger than the "clamp type" and "normal type" in the obliquity angle of LL, pelvic obliquity angle of lumbar vertebrae, PT, obliquity angle of sacrum, etc. The sacral plateau angle STA of the "shear type" was significantly smaller than that of the "clamp type" and "normal type", and the difference was statistically significant. Correlation test showed that PI was highly positively correlated with LL,SS and negatively correlated with STA. Conclusion 1. After SDSG classification, "shear type" was higher than "normal type", "clamp type" had greater LL,PT,SS and smaller STA;2.PI was highly positively correlated with LL,SS, and it was negatively correlated with STA.
