Spondylolysis & Spondylolisthesis | Orlando Orthopaedic Center
Spondylolysis is a stress fracture in one or more of the vertebrae in the spinal column. Spondylolysis is a common cause for lower back pain in active adolescents. When left untreated spondylolysis often progresses causing the effected vertebrae to weaken and shift out of alignment – a condition called spondylolisthesis.

Patients suffering from spondylolysis will be monitored closely to determine if the injured vertebra begins to move and spondylolisthesis develops. Continued physical therapy and other non-invasive methods may still be used when a patient first begins showing signs of spondylolisthesis. If the vertebra slippage continues, surgery is generally the next step in the treatment process.
In Spondylolysis, symptoms are often absent. Defects are then discovered only incidentally on x-ray made for other purposes. In Spondylolisthesis, injury may aggravate (permanently worsen) any symptoms, but rarely does a single injury cause symptoms in a person who previously had none. Symptoms generally begin insidiously during the second or third decade as an intermittent dull ache in the lower back, present with increasing frequency during walking and standing. Later, pain may develop in the buttocks and thighs, and still later unilateral sciatica may develop.
Spondylolysis and spondylolisthesis : Mr James Langdon
Most spondylolytic defects and cases of Spondylolisthesis are congenital. The prevalence of Spondylolisthesis in the general population is about 5% and is about equal in men and women. Spondylolysis and Spondylolisthesis most frequently involve L5, although L4 can also be affected and, rarely, more proximal levels.

There may be no objective signs in Spondylolysis, or in first or second degree Spondylolisthesis. The finding of Spondylolysis on x-ray in an adult is likely to be incidental, and not the cause of back pain if that pain did not commence in childhood or adolescence. Tightened hamstrings are present in the majority of those who are symptomatic. Tenderness and spasms of the paravertebral muscles may be present at the level of the vertebral defect and surrounding segments. Pain may be induced and increased by certain movements.

Spondylolisthesis is most often caused by spondylolysis. The cause of spondylolysis is not as clearly defined. Most believe it is due to a genetic weakness of the pars interarticularis. Both spondylolysis and spondylolisthesis can be present at birth or occur through injury. Repeated stress fractures caused by hyperextension of the back (as in gymnastics and football) and traumatic fractures are also causes. The most common cause in adults is degenerative arthritis.
spondylolisthesis explanation free
Spondylolisthesis is generally defined as an anterior or posterior slipping or displacement of one vertebra on another. A unilateral or bilateral defect (lesion or fracture) of the pars interarticularis without displacement of the vertebra is known as Spondylolysis. The pars interarticularis is the posterior plate of bone that connects the superior and inferior articular facets of a vertebral body.
