Description
Technical field
The invention belongs to technical field of medical instruments, and in particular to a kind of to repair lumbar vertebra compression fracture position using inner matter method
Specific purpose tool.
Background technology
Compressed fracture of thoracic vertebra and lumber vertebra is spinal surgery multiple injuries, the understanding and treatment one to compressed fracture of thoracic vertebra and lumber vertebra
It is straight to there is dispute.For the normal unstability compressed fracture of thoracic vertebra and lumber vertebra of function of nervous system, most of scholar advises row Thoracolumbar disk
Open posterior resets and combines in pedicle screw and fixes, so as to recovering spinal column normal sequence as far as possible and rebuilding spinal stabilization.
With a large amount of developments of such operation, have scholar find injected vertebral body Follow-up After during occur pedicle nail loosening, broken nail,
Corpus vertebrae replacement is undesirable, fix vertebral body RA in postoperative taking-up situations such as lose.There is the main cause of above-mentioned complication
Be fix using the system reset after, occur the change of ghost sample in vertebral body, front center pillar supporting role is lost, stress concentrations in
Nail rod internal fixation system, causes load irrational distribution.To prevent screw-rod Unstable internal fixation, at present frequently with measure
Have：Posterolateral fusion, pedicle are hindered bone grafting in vertebra, bone cement and hinder vertebra plasty, Jing and hinder vertebra pedicle screw fixation
And Pillar " pillar block " is inserted.Outside bone grafting can not be rebuild and hinder center pillar before vertebra afterwards, not have timely mechanical support effect, no
Can effectively prevent screw-rod system from fixing failure.Pedicle hinders bone grafting in vertebra, does not act on front center pillar mechanical support, difficult
To reduce the incidence rate that Unstable internal fixation and RA are lost, and there is bone grafting fibrosiss, bone grafting.Face
In the screw-rod system that bed is adopted, fixed row bone cement simultaneously hinders vertebra plasty, and vertebra height and front center pillar support function are hindered in reconstruction
Method, as bone cement percolation ratio is higher, be easily caused pulmonary infarction and nerve root, spinal cord injury, and the springform of bone cement
Amount is far longer than Intrapyramidal spongy bone, considerably increases the probability of adjacent vertebral bodies fracture.Jing hinders the fixation of vertebra pedicle screw can
Reduce Unstable internal fixation rate, may rebuild with screw and hinder that vertebra part support function is relevant, but still be not hinder vertebra reconstruction have efficacious prescriptions
Method.
Implantation Pillar " pillar block " can both overcome traditional screw-rod system reset after " ghost sample " vertebral body this lack
Point, and have different degrees of correcting to hindering vertebra deformity itself.But its average diameter is big compared with pedicle of vertebral arch, needs in implantation process
With dilator expanding channel step by step, the probability that pedicle of vertebral arch rupture occurs in art is higher.Once pedicle of vertebral arch medial wall ruptures, will be to god
Jing roots cause to damage so as to there are nervous symptoms.And its distraction reduction ability is not good enough, the reset response of vertebral body front pillar height is had
Limit.Therefore, it is to treat Thoracolumbar disk at present to find the safe and effective operation method for rebuilding center pillar before patients with thoracolumbar fracture hinders vertebra
The matter of utmost importance of compression fracture.
