Multiple segmental cervical spondylotic myelopathy (MCM) is a common type of cervical spondylosis and often requires surgical treatment. The main cause of its onset is cervical spine trauma, chronic strain, degenerative changes and congenital developmental abnormalities caused by spinal stenosis and posterior longitudinal ligament ossification. Clinical manifestations: limb numbness, weakness, walking instability, clumsy gait (cotton sense), hands fine movement decline.
Experts from the department of bone spine of qianfoshan hospital in shandong province said that the single open cervical canal expanded plasty has been recognized as one of the most effective methods for the treatment of cervical spinal stenosis, but there are shortcomings such as postoperative spinal canal restenosis and stubborn axial symptoms, limiting its promotion. Centerpiece titanium plate is a kind of micro-titanium plate of posterior cervical laminoplasty internal fixation system. It can expand and decompress the spinal canal, relieve the compression of nerves and spinal cord, and maintain the cervical vertebra motion after surgery. Compared with the traditional single-door expanded cervical laminoplasty, it has its advantages:
1. Minimally invasive, reducing excessive dissection and exposure of paravertebral muscle, and reducing intraoperative bleeding; The physiological structure of the posterior column of the cervical spine is retained, which is more consistent with the physiological characteristics from the biomechanics and reduces the postoperative cervical instability.
2. Support. As a supporting titanium plate, it can provide more stable support, reduce the pressure of scar tissue, effectively prevent the re-closing of the door, and avoid adhesion between the dural sac and surrounding tissues.
3, safe, centerpiece titanium plate, screw does not need to enter the spinal canal, reduce the risk of injury to the dural sac and spinal cord, high safety.
4. Early activity. In the past, long-term cervical braking after posterior cervical surgery often caused discomfort such as neck pain and stiffness.
Typical case: male, 42 years old, admitted to the department of bone and spinal column of qianfo hospital, shandong province for 4 months due to numbness and weakness of limbs. Imaging examination suggested ossification of posterior longitudinal ligament of cervical spine with obvious stenosis of cervical spinal canal. Hospital diagnosis of multiple segmental myelopathic type was longitudinal ligament ossification after the merger of cervical vertebra disease, cervical spondylosis the division director Zhang Kaining professor team after discussion, decisions for patients with cervical posterior single door vertebral canal expanded keratoplasty (centerpiece miniature titanium plate), postoperative patients with limb symptoms eased significantly, on the third day after normal activities on fields, 6 days after discharge.
