Background technology
Stiff type cervical kyphosis are a kind of high deformities of spine of disability rate, lead to patient to produce serious hunchback abnormal
Shape, sight line can not be looked squarely, and difficulty in opening mouth is even paralysed.Such patient's expectant treatment is invalid, and due to lopsided stiff fusion, the way of escape is cut
Bone orthomorphia is unique effectively treatment means.Posterior cervical bone-culting operation mainly has three steps：1) osteotomy, 2) reset, 3)
Fixing；Wherein second step resets is the most key step.Because after osteotomy, cervical vertebra and spinal cord are in quick condition, such as
The direction that fruit resets has deviation or dynamics control bad, easily leads to spinal cord or nerve root injury.
At present, in posterior cervical osteotomy orthomorphia, the method for reset is：Carry out through posterior Pedicle after centrum osteotomy, hand
Dynamic new line hand-reset, makes the curvature of cervical vertebra convex be changed into lordosis from rear.Such repositioning method risk is higher, because hand-reset
It is difficult to control the speed resetting and degree, and be difficult to during resetting keep stablizing of head；So frequently resulting in ridge
Marrow and nerve root injury, lead to patient's hemiplegia or paraplegia.In view of above-mentioned risk, the domestic present rarely such hand of hospital
Art, reports that the maximum-norm research of such operation also only has more than ten example cases in the world.
In conjunction with this kind of operating difficulty be big, time length feature, in surgical procedure, patient is in general anesthesia, lies prone in operation
On platform, the head leaning forward needs to support.For preventing patient body from being oppressed, body especially four limbs, eyes need to protect.Hand
When postoperative period is corrected to deformity of spine, especially it is noted that the speed and strength of the head of patient lifting upwards.
The orthopedic resetting means complex structure of existing cervical vertebra osteotomy, the requirement to operating personnel is higher；Expensive, for
In the case that existing operation is less, less economical.In sum, while needing one kind can meet corrective surgery requirement, economical
Property more preferably, the more easy orthopedic resetting means of cervical vertebra osteotomy of structure.
