Abstract:
[Objective]To observe clinical value of multi-slice spiral X-ray computed tomography(MSCT)volume rendering technique(VRT)and multi-planar reconstruction(MPR)in classification and treatment of tibial plateau fracture(TPF).[Method]From August 2005 to February 2009,49 fratures in 45 patients with TPF were treated.Their clinical data were studied retrospectively.There were 32 males and 13 females.The patients were aged from 20-65 years(mean 46 years).Four patients suffered bilateral TPF.All patients were examined with standard X-rays and 64-slice spiral CT scanner.Axial CT scans were processed with VRT and MPR.Their X-ray plain films and 64-slice spiral CT seans(including VRT and MPR)were performed to determine their fracture types and protocol.[Result]According to the VRT and MPR findings,13 fractures(13/49)classified by X-ray plain film were corrected,protocols were changed for 9 fractures(9/49),and 15 fractures(46.9%)of intereondylar eminence of the tibia and 6 fractures(28.6%)of proximal fibula were underdiagnozed.[Conclusion]MSCT(VRT+MPR)can clearly show the area and degree of tibial plateau collapse,the details of TPF and the delitescence fracture,help to determine TPF types,decrease the underdiagnosis rate and choose a rational protocol.The use of combined VRT and MPR is a supplementary means for X-ray plain film and axial CT scanning.which has great clinical value.
