Application of three-dimensional reconstruction in pelvic and acetabular fractures / 中国组织工程研究

ABSTRACT

BACKGROUND:Diagnosis of pelvic and acetabular fractures is difficult with a high misdiagnosis rate. It is necessary to diagnose pelvic and acetabular fractures rapidly and accurately. And patients suffer great injury, blood loss, from traditional open pelvis and acetabulum surgery, often complicated by neurovascular injury. Correct positioning and placement of internal fixator can reduce surgical complications. OBJECTIVE:To explore the new progress of three-dimensional reconstruction of pelvic and acetabular fractures in order to promote its clinical application. METHODS:A computer-based online search of PubMed database, CNKI database and Vip database between September 1996 and October 2013 was performed to search related articles using the key words of“3D, three dimensional reconstruction, pelvic fracture, acetabular fracture”in English and Chinese, respectively. The duplicate research or Meta analysis articles were eliminated. Final y, 41 articles were enrol ed for further analysis. RESULTS AND CONCLUSION:Through a three-dimensional reconstruction using a variety of post-processing techniques, such as multi-planar reformation, maximum intensity projection, shaded surface display and volume rendering, we can get high quality images at any angle. Various post-processing techniques interact with each other that can reduce missed diagnosis rate and misdiagnosis of pelvic and acetabular fractures. Moreover, three-dimensional reconstruction techniques can be used to design surgical approach, guide surgeon’s surgical program designed to simulate surgical procedures, reduce the complications caused by the dislocation of internal fixation, and reduce the surgical risk. Three-dimensional reconstruction is also used for postoperative fol ow-up review of fracture recovery.
