Description
Technical field
The present invention relates to a kind of artificial prosthesis, and in particular to used in a kind of vertebral resection Reconstruction it is internal can prolonged human
Work centrum.
Background technology
The infectious diseases such as tumor of spine, serious vertebral fracture and tuberculosis of spine can often cause the destruction of centrum, so that
Cause spinal cord, root compression and backbone angulation deformity caused by collapse of vertebra, now often must row Vertebrae resection.It is especially right
In tumor of spine, can often involve whole even more than centrum, it is tight to local stability destructiveness because excision extension is larger
Weight, if without effectively rebuilding, patient is postoperative often to occur Unstable internal fixation, and cause serious nerve function lesion and ridge
Post deformity.
Early in 1969, Hamdi was reported vertebral tumor excision and is substituted with prosthese first.Hereafter, it is miscellaneous
Artificial vertebral body starts gradually to develop.At present, artificial vertebral body is broadly divided into such as Types Below：Filled-type (such as bone cement), support type
(such as titanium net), and adjustable artificial vertebral body etc..What is be wherein most widely used surely belongs to titanium net, but titanium net and its internal bone grafting
Block is only contacted with upper hypocentrum in point, and the ability of osteoacusis is extremely limited, tends not to reach reliable bone grafting fusion.In addition titanium
The sharp edge of net may be formed to upper and lower terminal plate of vertebral body and cut, so as to result in implants sedimentation, loosening, even deviate from,
Even occurred in that in some patientss because of paraplegia caused by titanium net loose shift compressing spinal cord.
It can be seen that, preferable artificial vertebral body should not only possess good immediate postoperative stability, more need to take into account stability at a specified future date,
I.e. artificial vertebral body forms reliable bony union with neighbouring centrum.Should have concurrently simultaneously and insert the features such as convenience, height adjustable.
In recent years, numerous studies show that cellular structure metals not only have good histocompatbility and preferable biomethanics knot
Structure, it is often more important that it has good osteoconductive nature, is conducive to host's Bone Ingrowth, and fusion rate is high.
