中文摘要:

目的:探讨多层螺旋CT(MSCT)多层面重组图像(MPR)定量评价Colles骨折的可行性和可靠性。

方法:自2011年6月至2014年6月,选取拍摄腕关节正侧位X线片并行MSCT扫描的Colles骨折患者36例,男11例,女25例;年龄35~72岁,平均(42.5±5.4)岁。均在外伤后2 d内进行X线片和CT检查,检查图像均通过PACS局域网传送至工作站,根据X线正侧位片及MSCT-MPR图像分别进行远骨折块背侧嵌插深度、掌倾角和腕关节面塌陷错位度进行测量,间隔2周后再重复测量1次。比较前后2次测量结果及其相关性。

结果:36例患者中X线和MPR均能测量掌倾角,嵌插深度21例及关节面塌陷错位16例;伤后2 d的X线片测得掌倾角、嵌插深度和关节面塌陷度分别为(12.5±3.6)°、(4.5±2.1) mm、(3.7±1.6)mm,2周后分别为(4.8±2.2)°、(6.4±3.6) mm、(2.5±1.2) mm;前后比较各参数差异有统计学意义,中低度相关(r=0.681、0.640、0.345).MPR图像伤后2 d测量分别是(14.5±5.3)°、(4.2±1.2) mmm、 (5.7±2.3) mm,2周后分别为(13.2±2.6)°、(4.7±2.2) mm、( 4.6±2.1)mm;前后比较,关节面塌陷度有差异,其余差异无统计学意义(P>0.05),具有中度以上相关性(r=0.954、0.854、0.642).X线片测量的掌倾角、嵌插深度和关节面塌陷度与MPR比较,差异有统计学意义(P<0.05),具有低或中度相关性(r=0.454、0.532、0.378).

结论:借助MSCT的MPR图像,可对Colles骨折进行多个参数测量,作出定量评价,且重复测量可靠性更好。

Quantitative evaluation of Colles' fracture by Multislice CT multiplanner reconstruction: a feasibility study
ABSTRACT  

Objective:To investigate the feasibility and reliability on the quantitative evaluation of Colles' fracture by multislice CT (MSCT) multiplanner reconstruction(MPR).

Methods:A total of 36 patients with Colles' fracture from July 2011 to July 2014 were investigated in this study. There were 11 males and 25 females with a mean age of (42.5±5.4) years old (ranged 35 to 72 years). All the patients underwent anteroposterior and lateral X-ray films and MSCT scans on wrist joints within 2 days after trauma. Images were sent to the workstation through picture archiving and conserving system(PACS). One associate chief physician independently and respectively measured the dorsal intercalation depth of distal fracture block,palmar angle and dislocation degree of wrist articular surface collapse on anteroposterior and lateral X-ray film and MSCT-MPR. The time interval between the two measurements was 2 weeks. All the data between the first and second measurement on X-ray and MPR and the mean value between the X-ray and MPR was examined with paired t-test. The pearson analyzed their correlation.

Results:Among the 35 cases,35 cases of palmar angle,21 cases of intercalation depth and 16 cases of dislocation of wrist articular surface collapse could be measured on both X-ray and MPR. For the above parameters,the first measurement results were (12.5±3.6)°,(4.5±2.1) mm,(3.7±1.6) mm and the second measurement results were (4.8±2.2)°,(6.4±3.6) mm,(2.5±1.2) mm on X-ray films respectively. The first measurement results on MPR were(14.5±5.3)°,(4.2±1.2) mm,(5.7±2.3) mm,and the results were(13.2±2.6)°,(4.7±2.2) mm,(4.6±2.1) mm for the second measurement respectively. The three parameters between the first and second measurement on plain film had statistical difference and low correlation(r=0.681,0.640,0.345,P<0.05). The data between the first and second measurement on MPR showed that the dislocation degree of wrist articular surface collapse had statistical difference (P<0.05) and no statistical significance was found for the other two parameters (P>0.05),with the moderate correlation (r=0.954,0.854,0.642). The three parameters had low or moderate correlation with each other on X-ray(r=0.454,0.532,0.378,P<0.05),compared with the mean value on MPR.

Conclusion:Using MSCT MPR images may carry on the multiple parameter measurement of Colles fracture,to make quantitative evaluation,and repeated measurement is better reliability.
