The dysfunction of the sacroiliac joint is known to cause low back pain or leg pain. The leg pain is highly difficult and appear same as sciatica pain which is initiated by lumbar disc herniation. The sacroiliac joint exists adjacent to the spine bottom, underneath the lumbar region of the spine and over head the tailbone or coccyx.
The sacral bone is connected with the pelvis or iliac crest. This joint is characterized with certain features like not having motion, the forces of upper body are transmitted to the pelvis and legs through this region, structure that act as shock absorber, and it is strong as well as small pressurized by ligaments that surround the joint.
Anatomical Analysis Of Pain At Sacroiliac Joint
The reason for the pain is not clear while the change in the usual joint movement might be the initiation for sacroiliac pain. The source of pain is caused by large movement called hypermobility or instability. The pain is majorly observed in the lower back and it might extend into the groin region.
The pain might also result from hypomobility or fixation of the sacroiliac joint. The pain is experienced on a side of the lower back or buttocks region and it travels down the legs. The pain normally occurs above the knee and it also might continue to the foot or ankle. The pain due to a disturbance in the sacroiliac joint will be experienced same as that of sciatica or the pain extends towards the sciatic nerve which is caused by radiculopathy.
Symptoms Of Sacroiliac Joint Pain
Low Back Pain
The pain due to sacroiliac joint will exist towards either side of the lower back. The pain at the lower back starts from a small ache to an intensive pain that can stop the movement of the joint. The pain might extend into the buttocks as well as into the groin in the front.
Pain Radiating To Different Regions
The sacroiliac joint pain might sometimes lead to pain in the testicles in males. Rarely, there might be pain radiated into the lower limb which can be similar to sciatica.
Stiffness In The Back
The people suffering from sacroiliac joint pain will find it tough to turn around in bed, difficult to put shoes and socks on, and paining while stepping out of the car and going into the car.
The lower back will become stiff after raising from a long period of rest from sitting or in morning. One side of the lower back will be painful due to sacroiliac joint pain while driving very long spaces as the ligaments that surround the joint will be tender enough.
Diagnosis Of Sacroiliac Joint Pain
Diagnosing the non-functioning of sacroiliac joint is not that easy as the symptoms of sacroiliac joint pain are similar to other conditions such as facet syndrome, disc herniation and radiculopathy. Diagnosis can be done by physical examination or by an injection.
By moving the joint, the doctor will determine by the physical examination if the pain is lying at the sacroiliac joint. If the pain resumes after moving the joint and the reasons for other pain like disc herniation and MRI scan cannot explain it, then the doctor can confirm that the source of pain is sacroiliac joint.
An injection meant for sacroiliac joint serves as a tool for diagnosing sacroiliac joint block. The physician must be very much experienced and sufficiently skilled to send the needle into the concerned region of the sacroiliac joint. The injection is followed by X-rays to confirm that the sacroiliac joint is injected properly.
