Posterior-anterior approaches for cervical spondylotic myelopathy with stenosis of cervical spinal canal
In OPLL patients with less than 60% spinal canal stenosis, dynamic factors should be considered for the occurrence of myelopathy.
Methods: 28 cases with recrudescent intra-spinal canal tumors were analyzed, and the causes of recrudescence were predicated.
Fig. 2 Anterior-posterior border deossification behind L5 of lumbar with PLMN, arcuated bone block was bilateral faulting and palinal, the right crypt and spinal canal were stenotic.
The saggital diameter of spinal canal, Povlov ratio and dynamic spinal stenosis parameter were measured on X-ray.
The dumbbell-shaped sign and the relationship between spinal cord and tumor are two key points for the diagnosis of neurinomas in the spinal canal with MRI.
However, the changes of MR signal intensity of neurinoma are not distinguishable with those of meningioma and ependymoma in the spinal canal.
Results: the T1W imaging results of 6 cases show that GD - DTPA could greatly improve the demonstration of the brachial plexus both inside and outside the spinal canal part.
Objective To measure qualitatively the influence of AFC on disc height, neuroforamen height and the spinal canal volume of lumbosacral.
Relationship among the traumatic spinal canal stenosis,location of conus medullaris,and neurologic deficits in burst fracture of the first lumbar vertebra
Objrctive:To study the feasibility of keeping posterior of lumbar spinal canal stenosis and central lumbar disc herniation.
Also, the mass projecting into spinal canal can be cured by conservative treatment.
Summary of Background Data. There have been few reports of migration of cervical disc herniation to the posterior surface of the spinal canal.
Objective: To analyze the value of low-field MRI for neurilemmoma in spinal canal.
