Sacroiliac Joint Dysfunction

Sacroiliac Joint Dysfunction

There are many different terms for sacroiliac joint problems, including SI joint dysfunction, sacroiliac joint disease, SI joint syndrome, SI joint strain, and SI joint inflammation. Each of these terms refers to a condition that causes pain in the SI joints from a specific cause.

As with most other joints in the body, the SI joints have a cartilage layer covering the bone. The cartilage allows for some movement and acts as a shock absorber between the bones. When this cartilage is damaged or worn away, the bones begin to rub on each other, and degenerative arthritis (osteoarthritis) occurs. This is the most common cause of SI joint dysfunction. Degenerative arthritis occurs commonly in the SI joints, just like other weight-bearing joints of the body.

Another common cause of SI joint dysfunction is pregnancy. During pregnancy, hormones are released in the woman’s body that allow ligaments to relax. This prepares the body for childbirth. Relaxation of the ligaments holding the SI joints together allows for increased motion in the joints and can lead to increased stresses and abnormal wear. The additional weight and walking pattern (altered gait) associated with pregnancy also places additional stress on the SI joints.

 

  • Common SI Joint Pain Symptoms

    • Lower back pain (below L5)
    • Sensation in lower extremity: pain, numbness, tingling, weakness
    • Pelvis/buttock pain
    • Hip/groin pain
    • Feeling of leg instability (buckling, giving way)
    • Disturbed sleep patterns due to pain
    • Disturbed sitting patterns (unable to sit for long periods, sitting on one side)
    • Pain going from sitting to standing
    • Pain Referral patterns-
    • We can have some illustrations showing these
  • SIGNS

    • Compression test
    • Distraction test
    • Patrick Test
    • Fortwin finger test
    • Thigh Thrust test
    • Gaenslen test
    • Gillet test
      ( We will shoot demonstrations for these
      Or put up illustrations)
  • Causes of SI Joint Pain-

    SI joint injury is mainly caused by a combination of axial loading and rotational forces. For instance twisting while carrying a heavy object
    Trauma and degeneration are the two main causes of SI joint dysfunction and pain.
    Low Back Pain and SI Joint Pain Causes

  • What Causes SI Joint Pain?

    • Sacroiliac (SI) joint dysfunction and associated pain can be caused by a specific traumatic event (disruption) or can develop over time (degeneration).
      Sacroiliac Trauma (common events that may cause SI joint disruption)
    • Motor vehicle accident
    • Fall on buttock
    • Lifting and/or twisting
    • Natural childbirth
    • Pregnancy (chronic low back pain during and/or after pregnancy is frequently referred to pelvic girdle pain)
    • Sacroiliac Joint Degeneration (common causes)
    • Previous lumbar spine surgery (e.g., fusion of the lumbar vertebrae)
    • Stresses to the SI joint due to leg length differences, joint replacement, or scoliosis
    • Osteoarthritis
    • Previous iliac crest bone graft (ICBG)
    • Prior infection of the SI joint
    • Ankylosing spondylitis and Rheumatoid arthritis
    • Paget’s disease
    • Joint infections
    • Osteitis Condensans Ili
  • DIAGNOSIS

    The diagnosis in SI joint pain is a tricky proposition as at most times no single imaging modality like x ray, CT and MRI correlate satisfactorily with the clinical picture.
    MRI is generally resorted to rule out red flag signs and other disorders of the lower back.

    The gold standard in diagnosis is still a LA injected into the joint and pain relief is noted.

  • THE IASP Criteria

    Pain present in the region of the PSIS
    Clinical tests stressing the SIJ reproducing pain
    Selectively infiltrating the putative joint with local anaesthetic complete resolves the pain

  • TREATMENT

    Generally, these treatments can be divided into 2 categories: those directed at correcting the underlining pathology and those aimed at alleviating symptoms.. . To optimize outcomes, the identification and treatment of concomitant psychosocial issues is of paramount importance. This is best accomplished via a multidisciplinary approach.
    Conservative Management The non-interventional management of SI joint pain should ideally address the underlining pathology. In patients with true or apparent leg length discrepancy, this might include the use of shoe inserts to more equitably distribute the load borne by the SI joints. Because leg length discrepancies are frequently found in asymptomatic individuals (37) and many patients already compensate for their lower extremity length difference by altering their gait or posture, most experts recommend starting out cautiously with inserts that correct only half the incongruity. For SI joint pain resulting from altered gait mechanics and spine malalignment, physical therapy and osteopathic or chiropractic manipulation have been reported to reduce pain and improve mobility.

  • Intraarticular Injections

    Intraarticular injections with steroid and LA often serve the dual function of being therapeutic and aiding in diagnosis. To summarize these studies, most but not all investigators have found radiologically guided SI joint injections to provide good to excellent pain relief lasting from 6 mo to 1 yr .

  • Proliferative therapy

    Prolotherapy- has been advocated as a treatment for nonspecific LBP and SI joint pain The rationale behind the use of “prolotherapy” is that the ligaments and other soft tissue structures are of primary importance in the development of LBP. Thus, the injection of a drug promoting fibroblast hyperplasia should theoretically increase the strength and reduce sensitization of these structures

  • Radiofrequency Denervation Procedures

    Several investigators have performed radiofrequency (RF) denervation procedures in an attempt to provide prolonged pain relief to patients suffering SI joint pain. The techniques used have ranged from denervating the nerves supplying the SI joint ) to creating lesions in the joint itself , with one study using a combination of the two. The success rates of studies targeting the nerve supply are higher than those focusing on the joint itself, with approximately two thirds of patients reporting significant pain relief. The major drawback to percutaneous RF denervation procedures is that they should not be expected to alleviate pain emanating from the ventral SI joint

  • Surgery

    Fusion surgery is considered when all conservative measures fail

  • PREVENTION

    Pelvic floor exercises/ Kiegel’s exercises after pregnancy
    Avoid becoming overweight
    Some form of physical exercise to mobilises and strengthen spine
    Improved understanding of this highly misdiagnosed condition by doctors
