Abstract:
BACKGROUND: Acetabular malignant tumor reconstruction is to obtain pelvic stability and lower limb walking function to excise the tumor at safe margin.Excision range has been evaluated by MRI,CT,X-ray,which are subjective and lack preoperative design.Computer-aided three-dimensional reconstruction can evaluate tumor erosion range from all planes to accurately excise the tumor.OBJECTIVE: To evaluate the value of computer aided design in the treatment of acetabular malignant tumor.METHODS: One case with acetabular hemangiosarcoma was checked with lamellar CT scanning,which acquired some two-dimensional data in disease area.The three-dimensional reconstruction of anatomical model,design of cutting bone extent,design of individual prosthesis and sham operation were made by computer.Based on computer aided design proposal,acetabular tumor was resected,pelvic ring and right hip articulation were reconstructed with allogeneic semi-pelvis and individual total hip replacement.RESULTS AND CONCLUSION: The patient began to non-weight bearing walk with double crutches 2 months after operation.At6 months,the patient walked normally.The right hip joint motion was good with no pain.Postoperative X-ray film displayed individual prosthesis matched to pelvis.The patient fell a little numbness of skin in the lateral of right hip.No phlebothrombosis,prosthesis loosening or dislocation was found.Computer aided design has a good perspective of application in the treatment of acetabular malignant tumor.Individualized treatment can improve operation accuracy,reliability,convenience and curative effect.
