Description
Technical Field
The invention relates to the field of medical instruments, in particular to a personalized customized pelvic prosthesis and a manufacturing method thereof.
Background
The weight of a normal person is transferred from the lumbar vertebra to the pelvis downwards, from the pelvis to the ilium through the sacroiliac joint to the two sides, and then transferred to the left and right femurs through the left and right ilium respectively through the left and right hip joints. The cases of pelvic tumors are relatively rare, and require resection, both for primary tumors and for metastatic tumors. After the resection of the primary focus of malignant tumor around the pelvis, a great deal of tissue structure defects are often accompanied, including the damage of structures such as the pelvis, the ilium, the acetabulum, the femur and the like. Without surgical reconstructive repair, postoperative defects in bony support function and loss of motor function must be followed. The good restoration and reconstruction can obviously improve the postoperative life quality and labor capacity of patients. For tumors of the locomotor system of the extremities, there are various types of tumor-type prostheses for reconstructive surgery, these prostheses mainly adopting modular design. For the tumors of the central axis bone, especially the tumors of the pelvic region, the local anatomy and biomechanics of the tumors are complex, and the operation difficulty of reconstructing the structure and recovering the function is high.
The main means for reconstructing the pelvic bone comprise joint fusion, reconstruction of variant bones, inactivation of autologous tumor bones and reconstruction of artificial prostheses. However, patients who undergo joint fusion surgery are limited in their normal activities, have difficulty healing after implantation of autogenous and allogenic bones, and are at greater risk of infection. However, the pelvis of a human body has a special structural form, and the design of the artificial prosthesis is difficult to meet the requirements, so that the installation is difficult and the sciatic nerve is clamped and pressed after the operation. Furthermore, the different forms of prosthesis may lead to a considerable increase in the probability of loosening, breaking, dislocation of the prosthesis, and also to a considerable increase in the manufacturing price of the prosthesis, which increases the economic burden on the patient, or to a greater amount of material, and therefore costs, required for manufacturing the prosthesis. And the large-size prosthesis needs a larger wound in the operation, so that the recovery period of the patient is prolonged, and the infection risk is increased.
Accordingly, there is a need to provide a customized pelvic prosthesis and a method for making the same that overcomes the shortcomings of the prior art.
