Sacroiliac Joint Dysfunction

 Sacroiliac Joint Dysfunction

• Sacroiliac Joint (SIJ) Dysfunction is becoming increasingly diagnosed and treated as a contributing factor to low back pain
• SIJ is the joint formed between the two halves of the pelvis and the sacrum (the triangular-shaped bone at the base of the spine)
• The SIJ’s function is to distribute load between the lower limbs and the spine
• There is a very small amount of movement that occurs at the SIJ and if this is not controlled, it can result in an unstable joint and pain
• The SIJ is a strong synovial joint which is held together by bony alignment, ligaments and muscles; particularly the ‘core muscles’

Interesting facts

• 30% of low back pain is believed to be caused by the SIJ
• The SIJ provides attachment sites for 30-odd muscles
• SIJ injuries can result from a fall onto the bottom or knee, a lifting injury or may even occur during labour
• Pregnancy often causes SIJ pain as ligaments become stretched and the pelvis is under more strain.

What you can expect/look out for

• Pain with sitting, moving from sitting to standing, rolling in bed
• Pain in the pelvic and buttock region with walking and standing on one leg
• Groin pain
• Altered control of bladder function
  

Management options

• Physiotherapy guided ‘core muscle’ strengthening exercises
• Use of Real-time Ultrasound to view, correct and strengthen core muscle contractions
• Pelvic Belt for pregnancy
• Your doctor may prescribe anti-inflammatory medication
• Manual therapy to ‘realign’ the pelvis and SIJ
• Pilates or core based exercises
  
  

Hints for self-management

• Avoid high load transfer activities such as running, hopping, jumping
• Stretching tight muscles around the pelvis may help relieve symptoms (glutes, quads)
• Heat packs can help relieve tight muscles
• If symptoms come on during pregnancy, a SIJ belt may be advised for you to wear, as this can help support the pelvis

More information

• Your core muscles play an integral role in the stability of the SIJ
• Core muscles include: Pelvic Floor, Transverse Abdominus, Diaphragm and Multifidus
• Low back pain has been proven to inhibit activation of the core muscles
• Contributing factors to SIJ dysfunction include: muscle imbalances, leg length differences, poor posture, poor core stability, biomechanical abnormalities
