Description
Technical field
This utility model relates to the vertebral plate shaping blade plate of using in a kind of posterior cervical vertebral canal plastic operation art.
Technical background
What cervical operation was the most frequently used clinically is divided into two big class, anterior cervical operation and cervical posterior approaches by the otch route of entry.
The anterior cervical decompression fusion is reported at first in 1958 that by Smith and Robinson merging between the anterior cervical decompression vertebral body is the method that treatment myeloid form and cervical spondylotic radiculopathy are accepted extensively.The decompression purpose is to recover function of nervous system, and the fusion purpose provides stable, prevents that the intervertebral abnormal movement from causing neural further damage, keeps spinal column to line, keeps intervertebral height, and the maintenance curative effect prevents recurrence.
Usually get three cortical bones from patient self ilium cutter, implant intervertebral space and merge.But the higher complication such as bone district pain of getting makes more in recent years development adopt the Invasive lumbar fusion device (Cage) of circular or quadrate titanium alloy or carbon fiber (PEEK) material.In the art simultaneously assistance application titanium plate fix.
In recent years AM General company releases the product with Cage and the design of titanium plate " two one " formula, and PCB is fusion device fixedly, is applied to anterior cervical operation.
Cervical posterior approach is a kind of very effective operation method in treatment Multilevel cervical spondylotic myelopathy, congenital cervical spinal canal stenosis and cervical ossified posterior longitudinal ligament diseases such as (OPLL).
Cervical posterior approach is divided three classes: conventional laminectomy and decompression, expansion laminectomy and decompression and vertebral canal plastic operation art.
The laminectomy and decompression of conventional and expansion property because postoperative cervical vertebra posterior column structure destroys, affects the treatment along with cicatrization and contraction, long term often occurs sx, cervical region generation goose neck sample deformity.
For avoiding above-mentioned defective, people such as Pinglin of Japan in 1977, middle open country begin one's study " posterior cervical vertebral canal plastic operation art ".
1. single open-door formula vertebral canal plastic operation art: a side vertebral plate holostrome cuts, and a side vertebral plate only outside plate cuts, and vertebral plate is raised to a side, enlarges canalis spinalis.With the spinous process sutured on the joint capsule ligament.But postoperative " rate of closing the door " is high;
2. two (center) opening door vertebral canal plastic operation art: Miyazaki was improved in 1984 by the bright proposition in the rugged ocean of rock in 1980.But this art formula complicated operation, the specification requirement height needs special installation in the art.And can not carry out the nerve root canal decompression in the art, use less;
3. posterior cervical " Z " word plasty: propose by the mountain pass, but require carefully, patient in the art, have carelessness promptly to cause catastrophic effect slightly, so use seldom;
Mainly adopt three kinds of art formulas at present clinically:
At posterior cervical under lateral mass or pedicle of vertebral arch nail-plate system or nail-stick system internal fixation prerequisite, work half or full laminectomy for decompression: purpose is to strengthen the postoperative cervical stability, avoid postoperative generation goose neck sample deformity, but cost is multi-segmental or long segment to be fixed, merges, the postoperative cervical region is stiff, the devitalization function;
At posterior cervical under lateral mass or pedicle of vertebral arch nail-plate system or nail-stick system internal fixation prerequisite, make single open-door formula vertebral canal plastic operation art: advantage is to improve than the former, keeps the vertebral plate structure, reduces and prevents that postoperative scar from shrinking and compressing.Shortcoming is that the postoperative cervical region is stiff equally, the devitalization function;
3. single open-door formula vertebral canal plastic operation art, but improved: single open-door formula vertebral canal plastic operation art biggest advantage is the motor function that postoperative has kept each sections of cervical vertebra; Maximum shortcoming is that postoperative " rate of closing the door again " is very high, final operative failure.So each scholar tries to explore in recent years, tries hard to improve its art formula or fixed form, immobilization material.
The method that stresses to build of opening the door is a lot, comprises from body spinous process, ilium, allograph bone, artificial material, titanium plate etc.Moulding good sept is placed between door.Fix with absorbing suturing with thread management, or add again with small-sized blade plate and fix.Or with special vertebral plate open the door the shaping blade plate (opendoor laminoplasty, ODLP).
ODLP is present latest developments.ODLP is a kind of special-shaped blade plate.Select sizeable ODLP, the vertebral plate broken ends of fractured bone inserts in " plate mouth ", and plate places lateral mass, and the abdomen fork leans against the lateral mass broken ends of fractured bone.Adjust the plate position, 2.6mm * 5.0mm tapping screw riveting is fixed.As shown in Figure 1, 2.
The single open-door laminoplasty is that lateral mass and the vertebral plate intersection in a side interrupts fully, and the lateral mass of opposite side and vertebral plate intersection partly interrupt, and the people is for causing this place's incomplete fracture.The place of interrupting forms the place of opening the door fully, goes into sept in the disposal of opening the door, and with the expansion canalis spinalis, removes nerve compression; And the part place of interrupting forms " door-hinge ".
" single open-door laminoplasty " both can interrupt the lateral mass and the vertebral plate intersection in left side fully, and the lateral mass on right side and vertebral plate intersection partly interrupt, and make from left to right and open the door; Also the lateral mass and the vertebral plate intersection on right side can be interrupted fully, the lateral mass in left side and vertebral plate intersection partly interrupt, and make from right to left and open the door.
No matter when being L.H.flapped door, or during R.H.flapped door, ODLP one end is lateral mass fixedly, is positioned at the outside of operating field, and the other end is the vertebral plate broken ends of fractured bone fixedly, is positioned at the inboard of operating field.
The advantage of ODLP is to fix by nail-plate, rebuilds the stability of cervical vertebra posterior column structure, prevents that the vertebral plate that postoperative is opened from closing the door again.
But still there is very big defective in ODLP.The side plant bone mass is rebuild if open the door in the art in advance, can not absorb suturing with thread management fixing after, then be difficult for the ODLP that chooses length to be fit to, and be difficult for installing and fixing; If ODLP installs and fixes in advance, then plant bone mass is difficult for rebuilding ideally, or falls into canalis spinalis easily.And, the postoperative callus may be in the canalis spinalis hypertrophy, charge into, pressuring neural root or spinal cord reappear malaise symptoms, have influence on late result.
