Abstract:
BACKGROUND:Bone tumors around the Ⅱ section of pelvis are difficult to treat due to complicated anatomic structures.Using computer-aided technique,the excision range and prosthesis preparation can be individualized,which may obtain notable therapeutic efficacy in treating pelvic fractures in the clinic.OBJECTIVE:To discuss the application and the clinic effect of computer-aided technique in bone tumors therapy around the Ⅱsection of pelvis.METHODS:The pelvis model was generated with its CT data by rapid prototyping.Simulated bone resection and reconstruction were performed on the models.Then we designed surgical extension and made hemi-pelvic.Eight cases received resection of pelvic tumor and reconstruction based on computer-aided technique.RESULTS AND CONCLUSION:The resection of tumor and implantation of prosthesis were easily accessible.Two cases relapsed and 1 case loosened at 2 years after operation.According to Harris scoring criteria after total hip replacement,the scores of cases were well.The simulated resection and reconstruction of bone tumors around the Ⅱ section of pelvis based on computer-aided technique makes the operation easy and reconstruction precise,which produces good clinic results and offers a good promise for the application.
