ligamentum flavum function

A second component can be related to an age-related loss of elastic fibers and elasticity of the ligamentum flavum, contributing to their progressive loss of tension in the elderly (Nachemson & Evans 1968, Ramsey 1966). The capsules have a rich sensory innervation, consisting of mechanoreceptors for proprioception and free nerve endings containing substance P for nociception (Giles & Taylor, 1987; Yamashita et al., 1996). (See Figure 2-12.) This distensible ligament is composed of elastic fibers (80%) and collagenous fibers (20%), the elastic fibers imparting the ligament its yellow color and flexible nature (Bogduk & Twomey 1991). Fusion is achieved with or without instrumentation, consisting of an anterior plate and screws. Sagittal CT reconstructions or MR images are essential to determine the appropriate level, and plain radiography or fluoroscopy in the operating room is standard practice for localization. This spinal ligament is prone to calcification, Sean M. Esmende, Joon Y. Lee, in Operative Techniques: Spine Surgery (Third Edition), 2018. The ligamentum flavum should be resected laterally until the lateral border of the thecal sac is clearly visualized (Fig. The ligamentum flavum may undergo degeneration with age or after trauma. Many patients with thoracic disc herniations are asymptomatic. The decompression involves removal of more than 50% of the facet joint. However, when conditions are perfectly met, ligamentum flavum thickening can create symptomatic and possibly extreme stenosis symptoms in some patients. Hypertrophy or ossification of the ligamentum flavum was not recognized in the sections. This difference reduces, but does not eliminate, the need for epidural test dosing, and contrast imaging. 2 Such stress may cause hypertrophy of ligamentum flavum in manual worker. The supraspinous ligament helps maintain the upright position of the head. Timothy R. Deer, ... Douglas Stewart, in Neuromodulation, 2009. Surgical treatment is recommended for patients with myelopathy. Anterior cervical discectomy and fusion (ACDF) has been described with good results without the use of instrumentation. This treatment plan only works in cases in which a neutral or lordotic curve of the cervical spine is maintained. 5 Our previous epidemiological survey revealed a standardized prevalence rate of 63.9% in Chinese people. Hypertrophy of Ligamentum Flavum is a common finding in patients with a herniated disc, protruded disc, prolapsed disc or extruded Disc (Slipped Disc or Slip Disc).Injury, poor posture and longstanding spine conditions are the leading cause of Hypertrophy of Ligamentum Flavum. Both had large flaps of ligamentum flavum arising from the caudal lamina which infolded upon reduction and became trapped between the spinal cord and cephalad lamina. A Woodson dissector can be used to carefully free any adherent portions of dura. The interspinous ligaments are thin and almost membranous. In adults, the ligamentum arteriosum has no useful function. Both patients had neurological deficits preoperatively and regained normal function postoperatively. This condition is usually found in patients suffering from a herniated disc, prolapsed disc, extruded disc (or slipped disc) or protruded disc. Instability is seen on preoperative static radiographs or dynamic flexion-extension radiographs. As discussed, this ligament passes from the anterior and inferior aspect of the lamina of the vertebra above to the posterior and superior aspect of the lamina of the vertebra below. This yellow ligament is the strongest. Whereas ossification of the ligament is associated with increasing age and the presence of cauda equina syndrome, chondrogenesis in the ligament appears more associated with the presence of spondylolisthesis (Okuda et al 2004).

Josef B. Simon, Eric J. Woodard, in The Comprehensive Treatment of the Aging Spine, 2011, Thoracic myelopathy due to OLF or OPLL is not well treated by conservative methods such as nonsteroidal antiinflammatory medications and physical therapy.
