An L5 pars interarticularis defect refers to a structural abnormality in the lumbar spine, specifically at the fifth lumbar vertebra (L5) where a portion of the bone called the pars interarticularis is fractured or missing. This condition can lead to instability of the spine and may result in lower Back pain, often associated with activities that put stress on the lower back. It is commonly seen in athletes and can be a precursor to spondylolisthesis, where one vertebra slips over another. Diagnosis typically involves imaging studies like X-rays or MRI.
