Background
The sacrum is formed by fusion of 5 sacral vertebrae and is an important component of the pelvic girdle. The sacrum tumor occupies a certain proportion in the bone tumor cases, and surgical excision is the main means for treating the sacrum tumor at present. The sacrum not only has the functions of keeping the pelvic ring structure continuous and protecting viscera, but also has the function of supporting the spine. Thus, sacral defects will have an impact on the stability of the pelvis and spine. After the sacral tumor has been resected, the sacrum needs to be reconstructed in order to regain the integrity of the pelvic girdle.
The prior art generally employs staples, rods, and various structures of sacral prostheses for reconstruction. The stability of reconstruction by using the traditional nail rod is insufficient, the long-term clinical effect is poor, and the reconstruction is carried out by adopting various structures of sacral prostheses at present.
The anatomy of the sacrum is complex and different patients have different sacral structures. Meanwhile, the tumor ranges of different patients are different, and when the sacrum tumor is resected, the range of the different patients to be resected is different. After tumor resection, osteotomies of different shapes and sizes and angles of inclination are formed, and the sacral prosthesis is fixed with the pelvis by combining with the osteotomies. Moreover, since the tumor is not equally divided on both sides of the sacrum due to the tumor position, the shape, size and angle of the osteotomy on the left and right sides of the sacrum or ilium are different, and the existing sacrum prosthesis is of an integral type non-adjustable structure, the accurate matching with the osteotomy face after tumor resection cannot be realized during use, and the osteotomy range has to be increased according to the specification of the existing prosthesis.
In the prior art, some customized prostheses are needed to be custom designed and processed before operation according to the conditions of different patients, and the production cost is increased undoubtedly. This will increase the time and economic burden of the tumor patient waiting for the procedure.
