grade 1 isthmic spondylolisthesis l5 s1
Grade 1 spondylolisthesis, or a slipped disc, is a spinal condition that can be very painful. When one vertebra slips forward over the other, the result is uncomfortable friction exacerbated by motion. While pain is sometimes confined to the area of slippage, a slipped disc can also put pressure on adjacent nerve roots, causing numbness, tingling, and/or weakness in the extremities.
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.

Grade 1 spondylolisthesis can happen as the result of injury at any age, but it usually arises gradually in older adults. As the spinal discs undergo wear and tear, they may become dried out and compressed. This compression of the spine can cause the vertebrae to overlap one another, while the disc itself may protrude into the spinal canal, pinching nerves.
How is Grade 1 Spondylolisthesis Diagnosed and Treated?
The best way to confirm a diagnosis of grade 1 spondylolisthesis is through MRI and CT scans. These images allow your doctor to see the exact position of the slipped disc and the degree of slippage so far. Physical therapy is usually the first step toward managing symptoms of grade 1 spondylolisthesis. However, if this method fails to control pain, surgical treatment may be the best option.
Isthmic spondylolisthesis (Concept Id: C0410656)
Ulmer and colleagues proposed the "wide canal sign" to distinguish between isthmic anddegenerative spondylolisthesis. Using a midline sagittal section, they noted that the sagittal canalratio (maximum anteroposterior diameter at any level divided by the diameter of the canal at L1) didnot exceed 1.25 in normal controls and in subjects with degenerative spondylolisthesis. In patientswith spondylolysis, the measurement always exceeded 1.25.
The sagittal plane is best fordisplaying the abnormal anatomy ofspondylo-listhesis, T2-weighted imagesfor the canal and T1-weighted images forthe pars interarticularis and neuralforamina. The sagittal view clearlyshows the degree of subluxation and therelationship of the intervertebral disk tothe adjacent vertebral bodies and thespinal canal. Parasagittal images aregood for showing encroachment on theforamina by disk or hypertrophic bone. Loss of the normal fat signal cushioningthe nerve root is a sign for significantforaminal stenosis.

Approximately 90% of all spondylolytic spondylolistheses involve the 5th lumbar vertebra. 5% at L4, 3% at L1 L2 and L3, and 2% at C5 C6 and C7.
Explaining Spinal Disorders: Isthmic Spondylolisthesis
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.
This is known as adult isthmic spondylolisthesis.
Meyerding classification system is used to determine the degree of anterolisthesis of the 5th lumbar vertebra in relation to the sacrum. The sacral base is divided into 4 equal segments, and the alignment of the posterior surface of the 5th lumbar vertebral body is ascertained. In this method spondylolisthesis can be graded 1 – 4, depending on the amount of anterior shift of L5 in relation to the sacrum.
