In the standing position, the mean pelvic tilt angle, which is open at the back, is 13±6 degrees.
As pelvic tilt increases, the sacral plateau becomes more and more horizontal, while consequentially the body of the sacrum becomes vertical.
Symptoms may include: Your visit to the Orthopedic spine doctors at University of Maryland Orthopaedics will include an X-ray of your back.
You may also have a bone density scan for osteoporosis, and a CT (computed tomography) scan or MRI (magnetic resonance imaging) to determine the severity and rule out other possible conditions.
Children may not have any symptoms until about age 18.

Both conditions may not be noticed until it shows up in X-ray images for unrelated conditions.The classification proposed by Mac-Thiong and Labelle classification.Eight distinct subclasses were developed based on the grade of slip, the degree of dysplasia, and the balance of the pelvis in the sagittal plane.A thorough understanding of these spinopelvic parameters are essential when instrumenting the lumbar spine and the sacrum, since restoration of the lordosis and the extent of instrumentation to the correct level are essential to the success of the construct.This means that more the pelvic incidence the more rod contouring is needed to restore the sagittal spinal balance.Other nonsurgical treatment may include: Although these treatments can help you manage spondylolisthesis, it will not repair the fracture.You will have periodic X-rays to see if the vertebra is changing position.The etiology and degree of slip have been the cornerstones of the previous classifications.However, these classification systems do not provide guidelines to the natural history or the management of spondylolisthesis.Since the pelvic incidence is the sum total of PT SS, a vertical sacral endplate is associated with an anteverted pelvis, and a horizontal sacral end plate is associated with a retroverted pelvis.Since the value of the incidence is fixed for a given patient, the sum of the pelvic tilt and the sacral slope is invariable, and as one increases, the other necessarily decreases.
