Abstract

Lumbar spondylolisthesis is a common spinal condition in adults. The cranial vertebra sliding over the caudal one causes changes in the morphology of the neural foramen. Low back pain is the common presentation with or without radiculopathy mostly at L4-5 and L5-S1.
Wiltse and Newman classification: is the most practical and most widely accepted classification. including degenerative, isthmic, dysplastic, traumatic and pathologic
Isthmic (spondylolytic) Spondylolysis is a condition where there is defect in the pars interarticularis. A unilateral or bilateral, which commonly occurs at L4 or L5 vertebrae.
Non operative treatment is mainly conserved for those with no or mild neurologic complains, no spinal deformities nor gait abnormalities. And when low back pain is the predominant presentation. However some patients will ultimately require surgical intervention. Accepted indications for surgery include persistent or intolerable leg or back pain, progressive deformity (unusual in adults), worsening neurologic symptoms including foot drop and bowel or bladder dysfunction.
