X线断层融合技术对股骨颈骨折术后愈合过程的评价

Evaluation on Postoperative Healing Process of Fracture of Neck of Femur Based on X-ray Tomosynthesis

目的：探讨X线断层融合技术（DTS）对股骨颈骨折患者术后断骨愈合过程的应用价值,以了解断层融合技术在临床的实用价值.方法：回顾性分析2013年10月-2014年10月期间在某院住院并行手术治疗的36例股骨颈骨折患者,对36例患者在术后3个月、9个月时分别行普通X线和X线断层融合扫描,就两种成像方法产生的图像质量进行对比.结果：在术后3个月时,普通X线图像质量优秀率是52.78%（19/36）,断层融合技术图像质量优秀率是83.33%（30/36）,差异显著（P 〈0.05）;术后9个月时,普通X线图像质量优秀率是58.33%（21/36）,断层融合技术图像质量优秀率是91.67%（33/36）,差异显著（P 〈0.05）.结论：股骨颈骨折术后患者复查时首选X线断层融合扫面,能更好的显示骨折愈合情况,以供临床医师评估疗效.

Objective:To investigate the application value of X-ray digital tomosynthesis in postoperative healing process of femoral neck fracture,in order to understand fault fusion technology in the clinical practical value.Methods:A retrospective analysis was made on 36 cases of femoral neck fracture in our hospital during the period from October 2013 to October 2014,36 cases of patients were scanned in X-ray and X-ray DTS 3months,9months later after operation respectively,compare the quality of image achieved according to the 2methods.Results:3months later after operation,the excellent rate of the quality of the images achieved through X-ray was 52.78%(19/36)while the rate of the images achieved according to X-ray DTS was 83.33%(30/36).The difference was significant(P<0.05);9months later after operation,the quality of the image achieved through common X-ray was 58.33%(21/36),91.67%(33/36)through X-ray DTS,and the difference was significant(P < 0.05).Conclusion:X-ray DST shall be the first choice for patients with femoral neck fracture during reexamination,it would better reflect the healing of fracture and would help clinicians to make evaluation on curative effect.
