The application of computer aided rapid prototyping technology in diagnosis and treatment of complicated pelvic fractures
摘要
Abstract
Objective To evaluate the value of computer aided rapid prototyping technology in diagnosis and treatment of complicated pelvic fractures. Methods Twenty-two patients of complicated pelvic fractures were examined by thin-slice CT to gain two-dimensional data of the pelvis. Three-dimensional reconstructions of anatomical models were accomplished by computer aided technology. By rapid prototyping technology , the pelvic models were rendered , by which diagnosis and typing of pelvic fractures were finalized for operation project , mimic operation and guiding the operation. Results Three-dimensional reconstruction images and rapid prototyping pelvic models were extremely similar to what doctors saw in the operations. Preoperative mimic operation shortened the time of operation and reduced the volume of bleeding in the operation. All 22 cases were available for review in follow-up period of 6 ~ 24 months. Patients could sit up in 2 ~ 4 weeks after surgery , and walk with a crutch 6 weeks later. Pelvic fractures reductions were good in 22 cases. According to the Majeed's functional criteria , 16 patients were judged excellent and 3 patients were good. The excellent and good rate was 86.4%. Conclusions Computer aided rapid prototyping technology can overall, direct-viewing, and exactly display the three-dimensional shape of pelvis and spatial relation of anatomic structures. It is important for definite clinic diagnosis , typing and treatment.关键词
