The medical spondylolisthesis definition gives a basic description of this condition. While this is an accurate explanation, it is important to be aware of the more in depth spondylolisthesis definition that consists of understanding the different types and grades.
Basic Spondylolisthesis Definition
The medical definition of spondylolisthesis can be explained by looking at the word itself. Dividing up the word into two parts is a simple way to remember the basic spondylolisthesis definition.
Spondylo is the first part and means spine. Listhesis is the second part, which means slippage. When you put these two parts together, the basic spondylolisthesis definition is a forward slippage or displacement of a vertebra over the lower segment. It is generally the fourth or fifth lumbar section of your spine.
