Morphology and TGF-beta1 Concentration Analysis of Ligamentum Flavum in Patients with Lumbar Canal Stenosis and Lumbar Disc Herniation.

The most common spinal disorder in elderly patients is lumbar spinal canal stenosis, causing low back and leg pain and paresis. The aetiology of degenerative changes occurring in lumbar stenosis remain unclear: some authors hypothesize hyperplasia and others hypertrophy of the LF. The change in LF is known to be related to degenerative changes secondary to the aging process or mechanical instability.

Spontaneous spinal epidural haematoma. A case report.

Spinal epidural haematomas are infrequent events caused mainly by trauma or are iatrogenic following invasive spinal procedures (lumbar puncture, surgery or peridural anaesthesia). Spontaneous spinal epidural haematoma is a rare entity requiring emergency intervention in most cases. The incidence is estimated at about two to six cases per year.
