Objective: The goal of this study is to establish the mechanism(s) of progression of primarily spinal syringomyelia (PSS), the type of syringomyelia that is associated with pathology in the spinal column and not at the craniocervical junction. Our hypothesis is that when a lesion obstructs the spinal subarachnoid space, it shortens the segment of spinal canal that dampens the CSF pressure waves that are produced with each heartbeat and creates enlarged spinal subarachnoid pressure waves that act on the spinal cord above the block to drive CSF into the spinal cord and create a syrinx. After a syrinx is formed, enlarged subarachnoid pressure waves compress the external surface of the spinal cord, propel the syrinx fluid, and promote syrinx progression. Study Population: Subjects will have primary spinal syringomyelia associated with 1) intradural scarring which is post-traumatic, post-inflammatory, or post-operative, 2) intradural-extramedullary masses such as arachnoid cysts or meningiomas, and 3) extramedullary-extradural spinal lesions such as cervical spondylosis or spinal deformity, or 4) an intramedullary tumor. Design: Subjects will have testing before and after standard surgical therapy of syringomyelia. Testing includes measurement of CSF pressure, neurologic examination, CT-myelography, and MR scanning. Results of CSF pressure measurements before surgery will be compared to measurements from normal controls that were previously studied. The effect of surgery on CSF pressure, neurologic examination, CT-myelography, and MRI scans will be evaluated. Outcome Measures: The primary outcome measure is cervical CSF pulse pressure, which is the amplitude of the CSF pressure wave, compared to normal values. Secondary outcomes measures include change in CSF pulse pressure, neurologic examination, CT-myelography, and MRI scans between before and after surgery.
Potential benefits
Good to know: Potential benefits are defined as outcomes that are being measured during and/or after the trial.
