Lumbar Spondylolisthesis - Pathogenesis and causes

Lumbar spondylosis appears to be a specific phenomenon of aging. Most studies do not suggest any relationship between lifestyle, weight, height, physical activity, smoking and alcohol consumption or reproduction isotirc. Adipozitatea is seen as a risk factor in some populations. Effect of physical activity is controversial. Lumbar Spondylosis occurs as a result of newly formed bone depunderii in areas where the annular ligament is stressful.Bone spurs were long taken back because of back pain due to their size and frequency. Frequency of signs or symptoms among individuals with osteophytes is not higher than in those without.Spondylolisthesis is a fault between joint faces of the vertebral body, which may or may not be accompanied by translation of a vertebra over another, spondylolisthesis. Lumbar spondylosis is primarily a disease of middle age. As the lumbar discs and ligaments suffer wear and tear associated with daily colabeaza spaces between discs frequently. Thinning disc and ligaments surrounding the joints surrounding the girls is common. It eventually becomes calcified ligament atrophy. Spinal canal compromise or spinal nerve holes is a redoubtable complication.
Pathophysiology of intervertebral disc degeneration.Intervertebral discs undergo a "degenerative cascade" comprising three phases that occur over decades. Phase I describes the effects of initial dysfunction microtraumei repetitive circumferential cracks develop painful nerves and separating the fibrous ring of the disk surface layer which compromises the nutritional intake of the disc. These radial cracks merge and become the desiccation and disc height reduction. Devin protruzionate and affects the ability to maintain tissue water. Cracks can become the place with the increasing proliferation of vascular and nerve innervation and disk capacity to transmit painful stimuli.Phase II instability is characterized by progressive loss of mechanical integrity of the disk changes, resorption, breaking international and additional cracks, subluxation and instability.During the stabilization phase III disc space collapse and fibrosis continues with the formation of osteophytes and interdisciplinary bridges.
