【摘要】：目的:1、研究转子间骨折患者股骨近端髓腔形态特点;2、低能量损伤下不同股骨近端髓腔形态的转子间骨折严重程度对比;3、不同股骨近端髓腔形态对转子间骨折PFNA髓内固定手术的影响。方法:本研究通过收集山西大医院骨科于2012年12月至2017年1月诊断为股骨转子间骨折的患者术前、术后髋关节(包括股骨上段)正侧位X线、骨盆正位X线数字影像学资料及病例资料。用本院syngo.via影像学软件测量3项股骨近端髓腔内径参数和2项髓腔形态参数,对所得参数进行相关统计。并记录术中5项手术指标及骨折分型,分析在股骨髓腔开大指数(CFI)分型中不同几何形态的骨折分型所占比例及手术指标之间的差异。结果:1.转子间骨折患者股骨近端髓腔形态内径较以往统计数据明显增大,股骨髓腔形态为烟囱型患者比例约20%,明显高于以往统计结果。2.老年在低能量损伤下(跌倒损伤),转子间骨折以不稳定型骨折多见,股骨近端髓腔形态间差异不会显著影响骨折严重程度。3.股骨近端髓腔形态差异对PFNA髓内固定手术影响不明显。结论:虽然老年转子间骨折患者的髓腔内径较正常人群数据偏大,且烟囱型患者明显增多,但在低能量损伤下,髓腔形态的差异对骨折的严重程度影响较小,髓腔形态的差异对PFNA髓内固定手术影响较小。
[Abstract]:Objective: 1. The morphological characteristics of the medullary cavity of proximal femoral intertrochanteric fracture of 2; the severity of low energy damage under different rotor comparative morphology of proximal femoral medullary cavity fracture; 3 different proximal femoral medullary cavity effect on PFNA intramedullary fixation of intertrochanteric fractures. Methods: the study by collected in the Department of orthopedics from December 2012 to January 2017 in Shanxi hospital for diagnosis of femoral intertrochanteric fracture patients after hip joint (including proximal femur) and lateral X-ray, pelvic X-ray digital imaging data and clinical data. 3 proximal femoral medullary cavity diameter parameter and 2 parameters of pulp cavities of software the measurement of syngo.via image, and related statistics on the parameters and record the fracture and type 5 operation indexes in operation, analysis of opening index in the medullary cavity of femur (CFI) in different types of geometric shape of fracture type proportion and operation index Between the two groups. Results: the proximal medullary cavity diameter increased significantly compared with the previous statistical data of 1. patients with femoral intertrochanteric fracture, femoral morphology as the proportion of chimney type were approximately 20%, significantly higher than previous statistical results of.2. in elderly low energy damage (fall injury), with unstable fractures were more common intertrochanteric fractures morphology of proximal femoral medullary cavity, the difference between the.3. does not significantly affect the degree of fracture of proximal femoral medullary cavity were not significantly effect on fixation of intramedullary PFNA. Conclusion: Although the intertrochanteric fractures in the elderly patients with medullary cavity diameter than the normal population data is too large, and the chimney type patients increased significantly, but in low energy injury, differences in morphology of medullary cavity has little effect on the severity of the fracture, the difference of medullary cavity of PFNA intramedullary fixation has little effect.
