Definition / Description[edit | edit source]
Spondylolisthesis is a deviation of the spine when a shift of the vertebra occurs compared to the one just below. It is frequently situated at the fourth and fifth lumbar vertebra[1]. This shift is forward orientated, sometimes backwards, but this is rather uncommon.
A forward shift is called an anterolysthesis and a backward shift is called retrolysthesis. The degree of spondylolisthesis is generally mild, with a mean of 14%. Because of the shift it is possible that a nerve can be compressed or that the spinal canal is narrowed.
Symptoms that can occur with spondylolisthesis are low back pain, pain in the legs or a combination of both. Patients complain of deep, dull pain typically situated in the lumbosacral region after exercise, especially with an extension of the lumbar spine. The range of motion is diminished and the hamstrings are tense. When there is a compression of a nerve, patients mostly develop numbness, pain or tingling. If the compression is very severe it may be possible that the patient develops the cauda equine syndrome.
