Traumatic: Fractures arising from acute trauma to the spine may result in slippage of vertebrate.Dysplastic: This type of spondylolisthesis, also called congenital (present at birth) spondylolisthesis, is caused by abnormal development of the spine.
These types are: Isthmic: This is the most common type of spondylolisthesis in adolescents and young adults.
The slippage most commonly occurs in the lowest part of the spine, between the 5 sacral vertebrate, although it may occur at higher levels in the lumbar spine.
The spondylolisthesis is graded by measuring how much of a vertebral body has slipped forward over the body beneath it.
Approximately 5%-6% of males, and 2%-3% of females have a spondylolisthesis.
Many people with spondylolisthesis have no symptoms while others may have chronic low back pain, leg pain, or neurogenic claudication from spinal stenosis.
Spondylolisthesis is divided into 5 main types, based on the cause of the vertebrate slippage.Some examples are: Developmental Spondylolisthesis: This type of spondylolisthesis may exist at birth, or may develop during childhood, but generally is not noticed until later in childhood or even in adult life.Acquired Spondylolisthesis: Acquired spondylolisthesis can be caused in one of two ways: Many people with a spondylolisthesis will have no symptoms and will only become aware of the problem when it is revealed on an x-ray for a different problem.Degenerative: This is the most common type of spondylolisthesis in adults.As it’s name implies, vertebral slipping is caused by wear and tear degenerative changes in the disc and facet joints of the spine that weakens the attachments between two adjacent vertebrate to allow slippage.It is caused by a stress fracture in the back portion of the spine, an area known as the pars articularis.Even though these fractures usually occur in adolescents and young adults, symptoms may not occur until many years or even decades later.However, there are several symptoms that often accompany spondylolisthesis: Professor Rodts has done an excellent job at distilling the basics of spondylolisthesis into a concise easy to read layman's format.Anatomy and natural history are well described with the help of visual aids.Spondylolisthesis usually occurs towards the base of your spine in the lumbar area.This x-ray shows spondylolisthesis in the lumbar spine.
