Quantitative evaluation of Colles'fracture by Multislice CT multiplanner reconstruction:a feasibility study
摘要
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 ,pal-mar 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 correla-tion. 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.关键词
