Description: | Dr. Yuan treats a range of spinal disorders in patients of all ages including herniated discs and stenosis in the cervical, thoracic and lumbar spine. Dr. Yuan never recommends surgery first and is a thought leader in managing degenerative spinal stenosis. Many complain of low back and buttock pain. While there are several reasons this could occur, sacroiliac joint pain and dysfunction is one cause, and it often requires some level of medical intervention. SI joint pain and dysfunction is an ailment that commonly affects runners and other athletes as well as some people who do not identify as either.
The two SI joints are in a person’s pelvis, part of the stable ring structure that also includes the symphysis pubis. Several muscles including the hamstrings, abdominals, hip flexors and gluteal muscles attach to the SI joints. This joint is different from other joints because it only allows for about two degrees of rotation and less than one millimeter of movement backward and forward, but it is a joint nonetheless. The SI joint connects a part of the spine called the sacrum to the pelvis, and as a result it absorbs a lot of stress between these two bones, which can lead to pain, especially if there is an underlying problem.
About
The SI joint absorbs stress experienced in the legs during running and transfers it to the spine. If the muscles are weak or not working optimally, the SI joint takes the brunt of the load. Tightened ligaments often due to arthritis or hormone changes commonly caused by pregnancy can put the SI joint at greater risk of dysfunction.
To properly diagnose SI joint dysfunction, your doctor will have to do an examination. Symptoms are usually described as increased pain after running, standing from a seated position, walking up stairs or using other exercise equipment that stretches the muscles connected to the SI joint. Diagnoses often includes several types of imaging including x-ray, CT, a special type of CT called a SPECT and MRI, as well as fluoroscopically guided injections and sometimes lab work. |
