摘要
目的:探讨下肢全长拼接摄影测量肢体力线的准确度在实际应用中是可靠的。方法:对50例患者行全下肢摄影,应用全数字化大平板透视-摄影系统的拼接摄影功能得到全下肢全长,根据得到的影像测量髋-膝-踝角[180°-(测量的髋-膝-踝角)]得到畸形角度,再据测得的畸形角度做相关性分析。结果:畸形角度与术中截骨存在高相关性(相关指数=0.696,P<0.01)将畸形角度与术中截骨进行回归分析,畸形角度与术中截骨长度的线性关系存在。所获50例患者采用下肢全长拼接摄影肢体力线测量数据对术中截骨提供了可靠依据。结论:下肢全长拼接摄影可对肢体力线进行准确测量,为骨科手术截骨提供有价值信息。
Objective：Our study focus on the clinical reliability of the alignment measurement in slot radiography of full lower limbs using the splicing technique.Methods：50 patients were taken digital slot radiography using the splicing imaging technique of Shimadzu NIALVISION SAFIRE Ⅱ system.According to the imaging measurement of hip-knee-ankle angle,180°（hip-knee-ankle angle）was used as the measurement of the deformity angle.Results：There was high correlation between the deformity angle and the osteotomy length （correlation index= 0.696,P〈0.01）.Linear regression analysis indicated that the regression coefficient was 0.485.Conclusion：The results show that full lower limbs splicing radiography could strongly support osteotomy practice with accurate data.
