Spondylosis: refers to when you have degenerative osteoarthritis (OA) of the spine- this essentially means that the space between your vertebrae narrows as the protective cartilage that cushions the ends of the vertebrae wears down with age. With time, you may notice you have more of a flexed (forward bending) posture. Individuals suffering from this may experience lower back pain, leg pain, and/or numbness when standing or walking; symptoms may only seem to improve with sitting or lying down.
Spondylolisthesis: often refers to the progression of a spondylosis injury, but it may also be congenital or idiopathic in nature. Spondylolisthesis is defined as the displacement of one vertebra over the vertebral body below it (commonly known as a “step off” or “slip” at the L5/S1 level); individuals may even notice the presence of a bump by the area of the slippage. There are 5 different grades of this slippage, and it’s defined by the extent to which the vertebral body has slipped:
Grade I: O-25% Grade III: 50-75% Grade V: > 100%
Grade II: 25-50% Grade IV: 75-100%
Individuals with this may complain of localized pain that may come and go with certain activities, and this may be the most notable when bending backward or forward at the affected segment. They may experience radicular pain down to one or both legs as the vertebrae slides and causes compression of the nerve root below, tense hamstrings, loss of bowel/bladder (rare), and difficulty with balance or walking.
Spondylitis: known as axial spondyloarthritis, is an inflammatory disease that, over time, can cause some of the bones in the spine, called vertebrae, to fuse. This fusing makes the spine less flexible and can result in a hunched posture.
