Detecting joint instability Spinal Joint instability Joint instability is defined as a loss of spinal tissue integrity in the muscles, tendons and especially ligaments. It can be referred to as spondylolisthesis anterolisthesislateral listhesis rotatory subluxation or retrolisthesis, depending on which direction the vertebra slips.
This occurs when the vertebral isthmus a thin strip of bone connecting the superior and inferior facets of the spine becomes deformed somehow. If the problem is bilateral, posterior stability is lost and anterior slipping of the L5 vertebra in most cases over the sacrum can follow.
The cause of this is not fully known, but some researchers believe some individuals may simply have a congenital weakness of the isthmus.
Repetitive microtraumas or a single severe trauma can cause the onset of this condition. This disease is the main cause of lower back pain in adolescents and young athletes.
This disease is essentially benign, but it tends to advance over the years and be a cause of instability to the lumbar spine. For this reason it is better to control it with clinical and instrumental exams.

This damage may be congenital (present at birth), occur during an accident or be due to overuse or arthritis. Spondylothesis can occur in any age group: children and teens can become injured during sporting practices or events, while adults are at risk of age-related wear.
The first step is clinical diagnosis, although several tests may need to be carried out in order to confirm this diagnosis, an X-ray of the lumbosacral region is typically the most supportive of these tests. In the most advanced cases, listhesis can cause stenosis, resulting in nerve compression and symptoms radiating from this area.
Conservative therapy is preferred and consists of strengthening exercises that reduce the sliding movements of the vertebral body, increasing the retroversion of the pelvis and decreasing the lumbar lordosis. Further to this, physical therapy and manual therapies are used, depending on the clinical manifestation of the disease.Anterolisthesis is mainly caused by great impact on the spinal cord(anterolisthesis cervical spine or spondylosis) or the vertebra mainly the c4 and c5 (anterolisthesis c4 c5).
It could be due to falls from high heights, bullet wounds, impact from vehicle collisions, injury from sporting activities, and .
The condition may be congenital (hereditary), or the result of physical stresses on the spine or spinal degeneration. It may produce both a gradual deformity of the lower spine and also a narrowing of the vertebral canal, and can cause back pain, leg pain and other symptoms. Congenital spondylolisthesis: Congenital means "present at birth." Congenital spondylolisthesis is the result of abnormal bone formation.
Congenital spondylolisthesis is the result of abnormal bone formation. Spinal stenosis/degenerative spondylolisthesis are back conditions that are caused by the narrowing of the spinal canal. As people age, these conditions can develop due to the drying out and shrinking of the disc spaces between the bones (80% of the disc is made up of water).
Spinal deformity is a three-dimensional alteration of spinal alignment in both the coronal and sagittal planes. Scoliosis, strictly speaking, is a curvature greater than 10 degrees in the coronal (frontal) plane, as determined by measuring the Cobb angle (Fig. ). Congenital spinal abnormalities, such as thinning, improper formation or general defects in the pars interarticularis, facet joints or articular processes weaken the ability of the vertebral bone to defend against potentially listhesis-causing trauma.
