lumbar spinal stenosis

Stenosis of the spinal canal due to degenerative or traumatic changes at the level of the lumbar vertebrae. This condition causes back pain, often associated with pain that radiates into the legs, esp. when the patient is standing. Sitting often relieves the pain. The diagnosis is performed by spinal imaging, e.g., computed tomography or magnetic resonance imaging scanning. Treatments include physical therapy, braces, analgesic agents, and spinal surgery.

lumbar puncture
insertion of a needle and stylet into the subarachnoid space between the seventh lumbar vertebra and sacrum in most species except the dog, where the space between the sixth and seventh lumbar vertebrae is usually used; called also spinal puncture. A lumbar puncture may be done to measure the pressure of cerebrospinal fluid and obtain a specimen for examination, and to inject a contrast medium for special radiographic examinations such as myelography. As a therapeutic measure it is sometimes done to relieve intracranial pressure or to remove blood or pus from the subarachnoid space. A lumbar puncture also is necessary for injection of a spinal anesthetic.
