Description
Technical field
The present invention relates to a kind of titanium cable pedicle screw fixation operation methods.
Background technique
Spondylolysis and spondylolithesis of the lumbar spine is orthopaedics common disease, is the one of the major reasons for causing low back pain, and incidence is up to about 4%,
Wherein serious symptom, conservative therapy nonresponder need row operative treatment.Early stage uses outside simple Isthmic bone grafting and postoperative plaster corset
Fixation treatment, but curative effect is dissatisfied, and postoperative pseudarthrosis incidence needs to lie in bed for a long time and up to number up to 18%~81%
The plaster corset of the moon is fixed.Also there have been attempts with various across FSU unsettled methods add bone grafting treat spondylolysis and spondylolithesis of the lumbar spine, but with
It finds not only to generate stress force shelter reaction across FSU unsettled to fixed area but also neighbouring section can be increased significantly afterwards to answer
Power, thus the adverse effect for accelerating fixed area and neighbouring section interverbebral disc biochemistry and metabolism to substantially change.
Currently, spondylolysis and spondylolithesis of the lumbar spine is fixed, there are a variety of fixed forms, including FSU unsettled and across segment fusion to fix,
There are different degrees of deficiencies.FSU unsettled includes Buck isthmus screw method, pedicle nail vertebral lamina hook fixation and vertebral arch
Root follows closely U-shaped stick method.Buck isthmus screw method is fixed through the direct screw of the lumbar isthmus broken ends of fractured bone, so that Isthmic bone grafting amount influences bone grafting less
Fusion, is not suitable for the elongated patient of isthmus.Pedicle nail vertebral plate fixation is installed again need to sting except part vertebral plate ligamentum flavum, may
Hard mold capsule is damaged, operation precision is required high.The fixation of pedicle nail U stick belongs to indirect weighting and fixes, the installation damage spine of U-shaped stick
Between ligament, exist simultaneously the risk of fracture of spinous process.CN207755360 provides a kind of for treating the interior fixation of spondylolysis and spondylolithesis of the lumbar spine
Device, comprising: pedicle screw, for being implanted into pedicle of lumbar vertebral arch portion；Anatomical form vertebral plate hooking bar, comprising: barred body portion, one end are used for
Cooperate with the pedicle screw of implantation pedicle of vertebral arch and fastens；Hook body segment, set on the barred body portion the other end and with the barred body portion
It is integrally formed, hook body segment has the opening with vertebral plate shape adaptation, states vertebral plate by the open hook residence；The hook body segment phase
There is the first angle offset to become smaller with sagittal plane angle for barred body portion, the hook body segment has and hat relative to barred body portion
The second angle offset that shape face angle becomes larger.Fixation needs to cut off interverbebral disc and carries out bone grafting fusion between segment, loses vertebra
Between mobility, accelerate Adjacent segment degeneration, be not suitable for young patient.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of titanium cable pedicle screw fixation operation methods, realize
Simply, it is fixed suitable for the spondylolysis and spondylolithesis of the lumbar spine of young patient.
To achieve the goals above, the technical solution adopted by the present invention are as follows: a kind of titanium cable pedicle screw fixation operation method,
It is characterised by comprising: being screwed into two pieces of pedicle screws in Isthmic defect pedicle of vertebral arch, the isthmus broken ends of fractured bone and bone grafting are repaired；In Isthmic defect
The spinous process root mid point of vertebra drills, and penetrates titanium cable；Titanium cable is fixed on side pedicle screw nail tail with the head of a nail, is followed closely in the other side
Tightening titanium cable back spin marks closely cap after tail is screwed into the head of a nail, cuts extra titanium cable.
The invention has the benefit that
First, it realizes simply, belongs to FSU unsettled, do not sacrifice motor function between segment, do not destroy vertebral plate and rear is tough
Band tissue.It is acted on by titanium cable tension band come the direct press perpendicular isthmus fracture broken ends of fractured bone, meets the requirement of isthmus biomethanics, favorably
It is merged in Isthmic bone grafting, is not in fracture of spinous process, be suitable for not developed by isthmus without slippage or I degree slippage type Isthmic defect
It influences.The operation method of generation has wound small, and bleeding is few, restores the advantages that fast.
Second, it is widely used, titanium cable is not broken with pedicle screw firm connection, is fixed with meeting spondylolysis and spondylolithesis of the lumbar spine
Mechanical requirements.The fixed operation method of isthmus reparation is carried out in such a way that soft alloy cable is in conjunction with pedicle screw not
It is only applicable to spondylolysis and spondylolithesis of the lumbar spine operation, the fixation of cervical vertebra isthmus fracture fracture, the scope of application are also applied for after special designing
Extensively, fixed to Isthmic defect reparation that there is important clinical value, this traditional operation can be repaired to isthmus generates far-reaching shadow
It rings.
