Spondylolisthesis is a condition where one spinal bone (vertebrae) is not in alignment with the other. Typically, a slippage forward is found in the very low back at the 4th or 5th lumbar (low back) vertebrae. This is due to a stretching out of the ligaments that hold the bones together or possibly a fracture. With poor posture and weakened abdominals as well as spinal muscles, the increase in the angle of the spine becomes too much over time and misalignment of the bones occurs.
Symptoms can be mild such as general fatigue to the low back, achy pain or severe symptoms if there is compression on the nerves exiting the spine or spinal cord. There are varying degrees of severity. Most fall into a mild to moderate category that can be stabilized with improved posture and muscle strengthening. In severe cases, surgery may be necessary to fuse the area and bring stability back.
