What is chronic pars defects?

Answer 1

Chronic pars defects, also known as spondylolysis, refer to a condition where there is a stress fracture or defect in the pars interarticularis, a small segment of bone located between the upper and lower facets of a vertebra. This condition often occurs in the lower lumbar spine and can lead to Back pain, stiffness, and potential instability of the spine. It is commonly seen in athletes involved in sports that require repetitive extension of the spine, such as gymnastics and football. If left untreated, chronic pars defects can result in further complications, including spondylolisthesis, where a vertebra slips out of place.
