The Sacrum

– Written by Amber Novak, Craniosacral Therapist in Burlington, VT

The cranium and sacrum are at opposite ends of the spine. They work together to create a mechanism that “pumps” the cerebrospinal fluid throughout the system. This pumping mechanism creates the craniosacral therapist. The cerebrospinal fluid is vital to the health of the central nervous system. As the cranium fills with fluid the pressure increases, causing the system to move the fluid down the spine and into the sacral area. As the sacral area fills, pressure builds, triggering it to flex and pump the fluid back up the spine. This pumping mechanism carries the fresh fluid to the nerves and siphons the used fluid to the lymph system for recycling.

The sacrum is a very special bone. It is initially 5 separate bones at birth. They fuse into one big bone as we grow and develop in our teens and 20s. It is the triangular-shaped bone at the base of the spine and the tailbone protrudes from the end of it. It plays a large role in our ability to move around well.

The sacrum works hard to stabilize the network whole pelvis, spinal column, and cranium. It also attaches to the two halves of the pelvis, giving it flexibility and stability. Being at the base of the spinal column it also manages to support the weight of our head, torso, and upper limbs (about two-thirds of our body weight). as we sit, bend forward, stand up, and move around.

The sacroiliac joints (or SI joints for short) are on each side of the sacrum where it meets the pelvis. These two joints are the largest joints in the spine and are often injured. It is a misalignment of one or both of these joints that causes what is often perceived as low back pain.

When the sacrum has been injured or is compensating, it may not be able to expand and contract optimally, reducing its ability to move the spinal fluid smoothly. The sacrum may need help regaining its position and releasing tension to return to its ability to move the spinal fluid well.

I have been trained to look for restrictions in the tissues and help you to alleviate them. I have techniques that can coax a sacrum back into proper alignment and relax the tissues surrounding the area. This will smooth out the ebb and flow of cerebrospinal fluid, which will in turn alleviate tension in the craniosacral system and allow the central nervous system to function at a higher and more cohesive level. Healthy healing can begin.

When the tension is released clients feel much better, their lower back and hip pain is gone and mobility is much improved. It can often help with headaches, jaw pain, and neck pain as well. The sacrum and the cranium are very closely intertwined and if the base of support for the whole structure is eschewed, every structure that rests upon it may be unstable as well.
