Spondylolysis with or without spondylolisthesis is an often well-tolerated situation
SPONDYLOLYSIS - BILATERAL L5: Contributed by: ..
In patients with a pars defect there is a high incidence of spina bifida occulta, almost 13 fold. The spinal defect does not necessarily occur at the level of the pars defect. The hypoplastic and asymmetric facets that occur with spina bifida occulta are thought to increase the stress at the pars interarticularis thus predisposing to a defect.
X-ray imaging typically confirms bony abnormality, particular in cases of spondylolysis and spondylolisthesis. However, with a stress reaction, an x-ray may not reveal any abnormality.
Bilateral L5 spondylolysis without spondylolisthesis : ..
Subtype A :A fatigue fracture of the pars interarticularis. Subtype B :There is elongation of the pars interarticularis without a defect. Subtype C :Rare, due to severe hyperextention leading to acute pars fractures.
Acute traumatic fractures only involving the pars are rare, and certain disease processes which weaken the bone such as Osteopetrosis can cause spondylolysis. The most widely used classification is described by Wiltse, Newman and Macnab. Associated with a congenital abnormality of the upper sacrum or the neural arch of L5. There is usually no defect of the pars. Subtype A :A fatigue fracture of the pars interarticularis. Subtype B :There is elongation of the pars interarticularis without a defect. Subtype C :Rare, due to severe hyperextention leading to acute pars fractures. Also known as degenerative spondylolisthesis with an intact neural arch ie non spondylolytic spondylolisthesis. This is 10 times more common at L4, and no greater than 25% anterior displacement occurs. It is rare under 50 years of age, it is 6 times more common in females over 60 years of age, 3 times more common in blacks as in whites, and is 4 times more likely if associated with a sacralized L5. The mechanisms of displacement are thought to involve arthrosis of the zygapophyseal joint, disc degeneration, and remodeling of the articular process and pars. Can occur as an acute fracture of a portion of the neural arch other than the pars interarticularis ie a hangman’s type fracture of C2.(note this type is different from the pars fracture – Isthmic subtype C) Generalised or systemic disorders may affect the neural arch of the spine and cause spondylolysis and subsequent spondylolisthesis. Some of the more common forms are Paget’s disease, metastastatic disease, and Osteopetrosis. Radiological evaluation is the definitive method of confirming the presence of spondylolysis and spondylolisthesis. A complete plain film series of the lumbar spine and sacrum are recommended, and should include the following views.
Bilateral l5 pars defect without spondylolisthesis
In the white population there is a 5 -7% prevalence of pars defects with a male to female ratio of 2 to 1. In the black populations of South Africa there is a 2.4% incidence of a pars defect. In Alaskan Eskimos there is a 28-40% incidence of pars defects (? carrying upright in a papoose puts increased strain on the pars interarticularis).
Spondylolysis is an interruption of the pars interarticularis, this can either be unilateral or bilateral. Spondylolisthesis: an anterior displacement of a vertebral body in relationship to the segment immediately below, this can occur with or without a defect in the pars interarticularis.

Spondylolysis and Spondylolisthesis of the Lumbar …
Most disk herniations occur in a posterolateral direction into the spinal canal because the toughposterior longitudinal ligament is thicker and tougher in the middle and resists posterior extensionnear the midline. A herniated disk usually impinges on the nerve root as it courses inferiorly towardthe foramen at the next lower level. For example, an L4-L5 herniated disk impinges on the L5 root. The L4 root is likely unaffected unless there is lateral and cephalad migration of a free fragment intothe neural foramen.

Patients with lumbar disk disease canpresent with back pain or a radicular painsyndrome. The classic sciatic syndrome consists of stiffness in the back and pain radiating down tothe thighs, calves and feet, associated with paresthesias, weakness, and reflex changes. The pain fromintervertebral disk disease is exacerbated by coughing, sneezing, or physical activity. Pain is usuallyworse when sitting, and with straightening or elevating the leg. Disk herniations occur most oftenat the lower lumbar levels - 90% at L4-5 and L5-S1, 7% at L3-4, and remaining 3% at the upper 2levels.
