What is the Sacroiliac Joint?

Sacroiliac Joint Pain

At the very base of the spine, several vertebrae fuse to the back area of the pelvis known as the ilium, forming the sacroiliac or SI joints. These joints are supported by a system of muscles and ligaments that minimize uncontrolled motion during situations of physical stress or exertion, primarily the gluteal and deep abdominal muscles.

Walking upright relies on the ability of the sacroiliac joints to allow childbirth.

The sacroiliac joints play a critical role in absorbing impact vibrations, preventing the shock of walking, running and jumping from being transferred into another when walking.

Causes of Pain in the Sacroiliac Joints

Under normal circumstances, the interlocking structure of the bones helps them maintain the proper positioning. What causes SI joint pain is sacroiliac joint dysfunction, which happens as a result of to stiffen. These include progressive types of arthritis like Ankylosing Spondylitis, which involves persistent inflammation of joints along the spine.

Hypermobility is where the opposite situation occurs and there is an excessive degree of freedom, resulting in a lack of stability and poorly controlled movements that place to the surrounding connections and ligaments.

Facto Hypermobility

Hypermobility can be caused by a number of reasons, however, the injury is most common. Any impact or strain that is forceful enough can tear the ligaments connecting the joints. Injuries from auto SI joint pain.

Another facto the other, growing in intensity throughout the remainder of the pregnancy. In some cases, the problem persists well after the delivery of the child and the ligaments may remain in a compromised state unless strengthened again.

Inherent attributes like differences in leg length or tilting of the pelvis can affect gait and place uneven strain on the sacroiliac joints. Improper footwear may alter the heavily repeated motions of walking enough to have issues with hypermobility. The majority of lumbar spinal fusion patients are affected as well since the movement in their vertebrae is reduced and additional stress is placed on the sacroiliac joints.

Sometimes the reasons sacroiliac joint pain occurs is difficult to determine. It can flare up without provocation or warning and have no identifiable source. Healthcare professionals with knowledge, training, and experience in this area can provide a correct diagnosis and suggest an effective course of treatment.

What are Sacroiliac Joint Dysfunction Symptoms?

SI joint dysfunction most often presents as a deep, sharp pain in the low back. It usually originates near the posterior superior iliac spine, or PSIS, and radiates from there intock, and groin. It can also cause sciatic pain and frequently mimic a variety of back and hip problems, which makes accurate diagnosis difficult in some circumstances.

Pain is most often brought on after spending long periods of time in sustained positions of standing or sitting. Lying down can be just as uncomfortable for some people although some get temporary relief when lying sideways with a pillow between the knees. Certain other postures like sitting cross legged are very painful for most sufferers since this position places excessive strain on the sacroiliac joints. The majority of those with SI joint dysfunction tend to minimize discomfort.

Motions, like standing up, climbing stairs, and leaning or bending forward, are common triggers of sacroiliac joint pain, but sometimes simply walking is enough to cause aggravation for some. Activities such as intercourse can worsen the pain for some women, while others report escalated pain during menstruation or when urinating, however, these are rarer and only occur with about a tenth of SI joint dysfunction cases.

Identifying Sacroiliac Joint Pain and Other Associated

Arriving at a correct diagnosis for sacroiliac joint dysfunction requires knowledge and experience to numb the area. A sudden and significant improvement in pain levels could indicate that the joint is the source of the pain. In the majority of cases, the condition is determined through a physical examination and the information reported by the patient, so many health care professionals have problems evaluating these cases consistently.

Besides the other conditions which this type of joint pain can mimic, there are a few that are typically associated with sacroiliac joint dysfunction. In facet joint syndrome, the twisting motion bends the facets in the direction of rotation, compressing and crushing their articulated surface on that side, while tearing occurs on the opposite side. Another condition that arises from this is called nerve root, and involves the stretching of the nerves on the opposite side of rotation until they are deformed, which can lead to bilateral entrapment of the nerve roots. Torsion can also result in an annular bulge of the nucleolus purposes, which is the outer ring of the vertebral disc. L4 bulges are fairly common among those suffering from chronic sacroiliac joint dysfunction because of the tension in the attached iliolumbar ligament.

The long-term effects of sacroiliac joint instability have on muscles is very uneven. Muscles involved in posture are strengthened while phasic muscles are inhibited and weakened by the cumulative effect of the dysfunction. These changes can become permanent if the condition persists for long enough. Other muscles like the iliopsoas, adducto the lateral femoral cutaneous nerve, the pudendal nerve, and the sciatic nerve.

These conditions that arise in association with or as a result of chronic and prolonged instances of SI joint dysfunction stress the importance of not putting off treatment. Since some of these conditions cannot be corrected once the damage has been done and can cascade into still further complications.

How to Treat Sacroiliac Joint Pain

Effective treatment for SI joint dysfunction cannot be rushed. A lasting recovery requires a graduated approach, where the goals of each phase of healing and recuperation must be attained before moving on to the next phase of recovery.

First Step – Managing Pain and Inflammation

There are several strategies for SI joint pain relief, though most involve managing the sympto overexert without realizing it. As any physical therapist can verify, rehabilitation is never pain-free.

The key to target the source of the discomfort.

There are a variety of therapies that may be employed to relax and resume a less strained position.

Second Step – Regaining Strength and Range of Motion

After the pain and inflammation are under control, the task of building enough strength move without pain begins. It can take some time to build around. Once this has been done, the intermediate muscles are next, followed by the uppermost layers. If this process is done correctly and there are no additional complications, the pain will have ceased by this point.

Needs will vary from one person to maintain patience and perseverance in equal measure for an optimal recovery.

Third Step – Restoration of Normal Functioning

As the functioning of the sacroiliac joint gets better, focus shifts more to daily activities free from pain.

A therapist can best determine how the desired goals of a particular person may be met, and custoughen the injured area and reduce the chances of getting hurt again in the future.

It is important to the final stage occurs so slowly and gradually, that this third step is never entirely complete.

Fourth Step – Prevention of Future Issues

Once the problem has healed and the work of recovery is complete, it must be stressed that this last step is one that is never truly finished. SI joint dysfunction has a high chance of returning since in most cases the preconditions that led to the issue still exist and cannot be fixed in any permanent sense.

Whether the cause stemmed from an injury or genetic predispositions, the best and most effective treatments involve some sort program or routine that will maintain the strength of the supporting muscles throughout life. This will help minimize issues that can arise as age advances, reducing the need tors and medications in the future.

Approaching Therapy and Treatment

As the previous steps just illustrated, the most effective way to weight bearing exercises. The degree of soreness brought on by the exercises can serve as a guide in this process. The incorporation of wider ranges and types of motion should continue as treatment progress.

Some of the other therapies like deep tissue massage may provide temporary relief for sacroiliac joint dysfunction, but the pain inevitable returns as the tension do. Also, because of the strength and stability of the sacroiliac joint, the hands are not powerful enough to justify the lack of lasting positive results.

Is it Possible to Fully Recover from Sacroiliac Joint Pain?

Those who are suffering from SI joint pain will be happy to stay engaged in maintaining fitness and strength, especially after coming back from injuries and pain such as this, problems with the SI joint need never be an issue again.


In this instance, an athlete was originally diagnosed with minor quadriceps muscle strain and was treated for four weeks, with unsatisfactory results. When he came to our clinic, the muscle was not healing, and the patients’ muscle tissue had already begun to atrophy.

Upon examination using MSUS, we discovered that he had a full muscle thickness tear that had been overlooked by his previous provider. To mitigate damage and promote healing, surgery should have been performed immediately after the injury occurred. Because of misdiagnosis and inappropriate treatment, the patient now has permanent damage that cannot be corrected.

The most important advantage of Ultrasound over MRI imaging is its ability to zero in on the symptomatic region and obtain imaging, with active participation and feedback from the patient. Using dynamic MSUS, we can see what happens when patients contract their muscles, something that cannot be done with MRI. From a diagnostic perspective, this interaction is invaluable.
