Unstable spondylolthesis

In traumatic spondylolisthesis, any part (usually not the pars) of the neural arch can be fractured, leading to the unstable vertebral subluxation pathologic spondylolisthesis results from generalized bone disease, which causes abnormal mineralization, remodeling, and attenuation of the posterior elements leading to the slip. Degenerative spondylolisthesis: this is the most common form of the disorder with aging, the discs — the cushions between the vertebral bones — lose water, becoming less spongy and less able to resist movement by the vertebrae. Instability means abnormal sliding motion and change in the alignment during spinal movements in addition to mechanical spinal discomforts due to abnormal stresses on ligaments, disc and muscles, spondylolisthesis can be associated with nerve compressions due to a variety of reasons.

unstable spondylolthesis Spondylolisthesis had been diagnosed initially and treatment approaches included bracing, physical therapy and activity restriction none of these offered relief of symptoms and a progressive increase in pain was noted by the patient even with limited activity.

For some people with isthmic spondylolisthesis, the symptoms of pain that radiate down the leg and/or lower back pain can be severe and can adversely impact their ability to participate in everyday activities and simply function well enough to get through the day.

Spondylolisthesis is derived from the greek words “spondy”, meaning vertebra, and “listhesis”, meaning movement spondylolisthesis is an abnormal condition in which there is instability in the spinal column, as one vertebral body is shifting forward over the next vertebrae.

Unstable spondylolthesis

Spinal instability and spondylolisthesis often the most difficult to diagnose and certainly the most controversial, the basic concept behind spinal instability is that there is an excess of motion between two spinal segments that results in pain or compromised neurologic function. Sometimes a spondylolisthesis causes chronic back pain, and sometimes not the back half of the spine may slide slightly backward when this occurs, a slight “bump” can be felt when massaging that part of the back.

Isthmic spondylolisthesis: in isthmic spondylolisthesis, there is a defect in a portion of the vertebra called the pars interarticularis if there is a defect without a slip, the condition is called spondylolysis.
