Objective. Structures such as ligamentum flavum, annulus, and lamina play an important role in the segmental function. We proposed the surgical technique for achieving the sufficient preservation of segmental structures, in spite of sufficient removal of pathologic disc in the L5-S1 using the ligamentum flavum splitting and sealing technique. Methods. We retrospectively analyzed 80 cases that u...
OBJECTIVE A detailed investigation of the gross and microscopic anatomy of ligamentum flavum. METHODS Material included 14 lumbar vertebral columns obtained from the Anatomy Department, King Faisal University, Dammam during the period between January 2005 and January 2006. Height, width, and thickness of ligamenta flava were measured. A microscopic study was also performed. Computed tomograph...
OBJECTIVE To investigate the histopathological and immunohistochemical properties of degenerative changes in the ligamentum flavum of the cervical spine with calcium crystal deposition. METHODS Sections of the calcified ligamentum flavum harvested from 26 patients who required cervical decompression were examined by scanning electron microscopy (SEM), energy dispersive X-ray microanalysis, im...
Hypertrophy of the ligamentum flavum has been reported to occur in the prolapsed intervertebral disc syndrome. The ligaments from 28 patients were compared with a necropsy control group (18). Only minor histological anomalies were noted in two patients and the ligament was not thickened in cases of disc prolapse. In addition, there was no evidence to suggest previous trauma to the ligaments ass...
Lumbar spinal canal stenosis (LSCS) is one of the most common spinal disorders in elderly people, with the number of LSCS patients increasing due to the aging of the population. The ligamentum flavum (LF) is a spinal ligament located in the interior of the vertebral canal, and hypertrophy of the LF, which causes the direct compression of the nerve roots and/or cauda equine, is a major cause of ...
What are the causes of cervical myelopathy? Myelopathy is caused by any pathologic process that interferes with transmission of signals through the spinal cord. In regard to orthopedic surgery, the most common cause of this disease is due to cervical degenerative disc disease putting pressure on the spinal cord in a condition referred to a cervical spondylotic myelopathy. The remaining referenc...
Neurological injury is a potential complication of anterior cervical discectomy (ACDF). Iatrogenic trauma, hypoxic-ischemic damage during surgery or epidural hematoma could cause neurologic deterioration after surgery. This is the first case being reported of neurologic deterioration after an anterior cervical discectomy due to ligamentum flavum buckling. The case illustrated an uncommon cause ...
