Postoperative evaluation of MSCT three-dimensional reconstruction for distal radius autogenous bone transplantation / 实用放射学杂志

ABSTRACT

Objective To evaluate the clinical value of three-dimensional MSCT reconstruction in autogenous bone transplantation surgery.Methods 72 cases with complex wrist fractures were performed X-ray and three-dimensional MSCT reconstruction before and after articular distal radial autogenous bone transplantation surgery.Results Among 72 cases of X-ray diagnosis,62 cases obtained clear imaging to make a diagnosis;however,the other 10 cases need to use again three-dimensional reconstruction with MSCT to make a diagnosis.The X-ray accuracy of diagnosis was 87％,the three-dimensional reconstruction of MSCT accuracy of diagnosis was 100％, and the difference was statistically significant (P <0.05 ).Postoperative patients were followed up,with reference to the fracture healing efficacy standard,the treatment by autogenous bone graft after MSCT three-dimensional reconstruction allows patients to fracture healing well.Conclusion MSCT scanning and three-dimensional reconstruction are organically combined.A three-dimensional image can comprehensively and accurately display the three-dimensional structure and anatomical relationship of various parts of the distal radius,be valuable for preoperative intra-articular distal radius comminuted fracture,select the appropriate surgical approach and evaluate the postoperative values.
