Computer 3D Reconstruction Technology

Computer three-dimensional reconstruction technology has important significance in simulating the pelvis, determining the scope of malignant tumor resection, and individualized design of the prosthesis. The soft tissue infiltration in the pelvis is about 10cm. CT scan of the lesion and pelvis, computer three-dimensional reconstruction, using laser rapid prototyping technology to produce a physical pelvic model. According to the model, the osteotomy range and osteotomy markers were determined, and the lesions were simulated. Basic Information Specialist classification: Oncology examination classification: CT Applicable gender: whether men and women apply fasting: not fasting Tips: Check before taboo: Maintain normal diet and schedule. Normal value Normal people do not need to use computer 3D reconstruction technology. Clinical significance Abnormal results A computer-based three-dimensional reconstruction technique can be used to create a prosthesis that matches the lesion. Patients with skeletal lesions or patients who need to be placed in the prosthesis to be examined. Precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for inspection: Actively cooperate with the doctor's work. Inspection process Take acetabular chondrosarcoma as an example: soft tissue infiltration in the pelvis is about 10cm. CT scan of the lesion and pelvis, computer three-dimensional reconstruction, using laser rapid prototyping technology to produce a physical pelvic model. According to the model, the osteotomy range and osteotomy markers were determined, and the lesions were simulated. Continue to use the computer to create an acetabular prosthesis that matches the resected lesion, with a fixed handle that is fully compliant with the surrounding pelvic tissue. Surgery and prosthetic equipment were simulated by prosthesis and patient tumor pelvic models. The Smith-Peterson and Radley combined approach was used to expose the hip, pubic symphysis, and ischial branch. The tumor was resected according to the three-dimensional reconstruction model and the prefabricated prosthesis was implanted. The prosthesis was firmly fixed with the iliac crest, pubis, and ischial residual. . The cement is used to fix the acetabular lining and replace the femoral head.
