Metrizamide is largely replacing iophendylate (Pantopaque) for routine lumbar myelography. Better visualization of the nerve root sheaths should make metrizamide myelography more sensitive in detecting laterally herniated disks, such that epidural venography might be required less often. However, that expectation has not been realized. In over 800 consecutive myelograms, one-half obtained with ...

Oxygen-ozone intradiscal and periganglionic injection is a minimally invasive procedure first applied clinically in the peridural treatment of lumbar sciatic pain and lumbar disk herniation. A reduction in herniated disk volume is one of the therapeutic aims of the gas mixture, as disk shrinkage may reduce nerve root compression. Another reason for using medical ozone to treat disk herniation i...

A 22-year-old woman with type I Ehlers-Danlos syndrome had severe radicular pain in the lower back. A laterally herniated lumbar disk was seen on myelography. Pain and walking improved after lumbar laminectomy. A chronic focal seizure disorder was associated with CT evidence of a congenital structural defect of the brain.

Low back ache arising due to a herniated lumbar disk with radicular pain the lower limbs is commonly occurring problem evaluated by spine surgeons. Conservative treatment has usually been proposed for an acute prolapse in cases without significant motor or sensory deficit. Spontaneous radiological regression of extruded complete symptomatic recovery occasionally reported. A case conservatively ...

Study Design Biomechanical study on cadaveric spines. Objective Spinal bending causes the annulus to pull vertically (axially) on the end plate, but failure mechanisms in response to this type of loading are poorly understood. Therefore, the objective of this study was to identify the weak point of the intervertebral disk in tension. Methods Cadaveric motion segments (aged 79 to 88 years) were ...

OBJECTIVE To correlate spinopelvic balance with the development of degenerative spondylolisthesis and disk herniation. METHODS This was a descriptive retrospective study that evaluated 60 patients in this hospital, 30 patients with degenerative spondylolisthesis at the L4-L5 level and 30 with herniated disk at the L4-L5 level, all of whom underwent Surgical treatment. RESULTS Patients with ...

Fifteen nuclear magnetic resonance (NMR) studies of 14 patients with herniated lumbar intervertebral disks were performed on the UCSF NMR imager. Computed tomographic (CT) scans done on a GE CT/T 8800 or comparable scanner were available at the time of NMR scan interpretation. Of the 16 posterior disk ruptures seen at CT, 12 were recognized on NMR. Diminished nucleus pulposus signal intensity w...

Forty patients with symptoms and signs of radicular disease or spinal cord involvement secondary to cervical spondylosis were studied with myelography (using nonionic water-soluble contrast medium) followed by computed tomographic (CT) myelography. In 17 patients CT was also performed before myelography. CT myelography adds useful information to the myelographic findings. Cord compression is be...
