Sacroiliac

The sacroiliac (ISG) or sacral iliac joint connects the lower spine to the pelvis. This connection is held by tight ligaments and is very little mobile, but can be postponed by bad postures or injuries. Even minimal shifts can lead to pain. Read everything important about the sacroiliac joint!

What is the sacroiliac joint?

The sacroiliac joint (ISG) is the articulated but almost immobile connection between the lower spine (sacrum) and the two ilium (ilium). So there are two iliosacral joints in the body. The bony articular surfaces are covered with a cartilaginous layer. Strong, tight band connections allow only minimal tilting or sideways movement, but they are important for regulating the width of the pelvis - especially at birth. During pregnancy, therefore, the ligaments (as well as the symphysis = pubic symphysis) loosen by the hormonal switch to allow the passage of the baby's head at birth.

What is the function of the sacroiliac joint?

The sacrum as the lower part of the spine has to transfer the weight of the trunk to the two hip legs and on to the legs - the price of the upright gait. However, in order to be able to hold the hull load and not tilt forward into the pelvis, the articulated connection between the sacrum and the two iliacs - the sacroiliac joint - must be well fixed, which is ensured by strong, tight ligaments. From the sacrum several such ligaments pull to the intestine and seat legs. These wristbands are reinforced by several smaller bands. The sacrum and the hip legs form a vaulted arch, through which the hull load is transferred to the legs. As you walk, there are alternating tiny movements in the two sacroiliac joints. The tight bands limit the range of motion.

Where is the sacroiliac joint located?

The sacroiliac joint is part of the pelvic girdle. It connects the lower spine (more precisely, the sacrum) with the two intestines.

What problems can the sacroiliac joint cause?

In the sacroiliac joint (ISG) syndrome sufferers feel pain in the joint, which can also radiate into the back and into the legs. The symptoms increase during the course of the day and are particularly noticeable when lifting loads, straightening up from a stoop and when standing for a long time.

Ankylosing spondylitis (Ankylosing spondylitis) is a chronic inflammatory rheumatic joint disease, usually in paired sacroiliac it starts. Early symptom is nocturnal back pain.
