Abstract

The invention provides a vertebral prosthesis which is characterized in that a bone grafting space is arranged in a base body, and the base body is mounted in a vertebral body; a connecting hole is formed in the side wall of the base body and communicated with the bone grafting space, and the connecting hole is exposed out of the vertebral body; a bone grafting hole is formed in the end wall of the base body and communicated with the bone grafting space; a fastener penetrates in from the connecting hole and penetrates out from the bone grafting hole; and a connecting part which is matched with the fastener in a limiting manner is arranged in the connecting hole. According to the technical scheme, the problem that in the prior art, a vertebral body is prone to collapse is effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a vertebral body prosthesis. Background technique [0002] Cervical spondylotic myelopathy is a more serious type of degenerative cervical spondylosis. Due to the compression of the cervical cord or nerve roots, it often causes neurological symptoms such as paresthesia or paralysis of the limbs, and the disease develops progressively. Surgical intervention to relieve spinal cord or nerve root compression, prevent further deterioration of neurological function, and improve the patient's quality of life. [0003] Subtotal cervical corpectomy has the advantages of sufficient decompression of the spinal cord and immediate stabilization of the cervical spine after surgery, and has been widely used in clinical practice. [0004] In a related technique, a cervical subtotal corpectomy involves the implantation of a titanium cage to decompress the spinal cord or nerve roots. ...
