Abstract：Objective To study the 3D manifestation and clinical value of joint surface injury after joint disassembly under the computed tomography (CT) volume rendering for extremities fractures patients.Methods Ninety-nine extremities fracture patients were taken "CT-VR conventional method" and "CT-VR joint disassembly method" after CT scan,respectively.The results of joint surface injury were compared and analyzed between two groups.Results For all 99 cases,images by using "CT-VR joint disassembly method" could display full extremities fracture surface injury directly and completely.The main CT features of manifestation were as below:feature of single joint surface crack,feature of intra-articular dissociable bone chips and joint surface bony defect,feature of intra-articular avulsion-diastasis,feature of several joint surface cracks,feature of joint surface fragmenting and mismatch;feature of joint surface fragmenting and separate deformation.Conclusion The colorful 3D images after post process by "CT-VR joint disassembly method" can show severity and specified details of extremities fracture joint surface injury exactly.It is useful references to determination treatment options for an extremities fracture.
