What does Anterolisthesis of L5 on s1 mean?

This is basically another term for spondylolisthesis. Anterolisthesis is a spine condition in which the upper vertebral body, the drum-shaped area in front of each vertebrae, slips forward onto the vertebra below. The amount of slippage is graded on a scale from 1 to 4.

What are the grades of Anterolisthesis in MM?

Anterolisthesis can be graded: Grade 1 is less than 25% slippage, grade 2 between 25%-50% slippage, grade 3 between 50%-75% slippage, and grade 4 greater than 75% slippage. Symptoms of anterolisthesis depend on the severity, location, and cause.

How many mm is spondylolisthesis?

Spondylolisthesis was diagnosed in 120 patients. The mean range of the slip in the midline sagittal image was 9 mm, with a range of 3–17 mm of slip (Meyerding Grade I–IV).

What causes pain in the L5 – S1?

Intermittent or continuous back pain.

  • Spasm of the back muscles.
  • Sciatica – pain that starts near the back or buttock and travels down the leg to the calf or into the foot.
  • Muscle weakness in the legs.
  • Numbness in the leg or foot.
  • Decreased reflexes at the knee or ankle.
  • Where is L5 S1 on your spine?

    The lumbosacral joint, also called L5-S1, is a term used to describe a part of the spine. L5-S1 is the exact spot where the ​lumbar spine ends and the sacral spine begins. The lumbosacral joint is the joint that connects these bones.

    Where is the L5 and S1 vertebrae?

    The sacrum also has five fused bones, labeled S1 through S5. The L5 vertebrae sits on top of the S1 vertebrae. Compression of the nerve root between L5 and S1 vertebrae can cause pain, numbness, tingling and weakness in the leg on the affected side.

    What are L5 and S1 vertebrae?

    The lumbosacral joint (L5-S1) is a joint in the spinal column between the last vertebra of the lumbar region and the first vertebra of the sacral region. At this point, there is a shift in the curvature of the vertebral column from a forward curvature in the lumbar region to a backward curvature in the sacral section of the spinal column.
