What is the base of the sacrum called?
The base of the sacrum is the widest part and is connected to the L5 lumbar vertebra via the lumbosacral joint. Even though it's called the base, it is actually at the top (superior aspect) of the sacrum rather than at the bottom.
What does the sacrum do?
Overview Overview The sacrum is the triangle-shaped bone at the end of the spine between the lumbar spine and the tailbone. The sacral spine consists of five segments, S1 - S5, that together affect nerve communication to the lower portion of the body. It is important to understand that the spinal cord does not extend beyond the lumbar spine.
What does the sacral canal connect to?
The sacral canal is a hollow space that runs from the top (base) of the sacrum to the bottom (apex). The sacral canal serves as a channel at the end of the spinal cord. The sacrum connects (articulates) to the iliac bone on either side at an attachment point called the auricular surface.
What is the sacral angle of the lumbar spine?
The Lumbosacral Angle Defined. The degree of sacral base tilts vary in individuals; they can be, relatively speaking, steep or flat, or places in between. As the base of support for the spine, then, this sacral angle determines, at least in part, the degree of curve in the lumbar, thoracic and cervical areas.

30 years of ageThe adult sacrum consists of five fused sacral vertebrae. At birth, each vertebral body is separated by an intervertebral disc. The two caudal bodies fuse at approximately the 18th year of life, and the process of fusion continues rostrally until the S1–2 interspace finally fuses by 30 years of age.

What is the angle of the sacral base?
What we now know is that the efficiency of the low back architecture in a person is much greater from an engineering point of view when the sacral base falls between 36°-42°. If the angle is outside this range, the efficiency of the supportive joints and tissues goes down proportionately, and increases the vulnerability of the individual with regard to injury and degenerative potentials in their life.
Why is sacral base angle important?
The importance of the sacral base angle is huge when considering your patient from an engineering, or architectural perspective. When the angle is increased or decreased from normal, there will be a significantly reduced capacity of the low back over the life of that patient. Secondly, imbalances and abnormal weight distribution have been shown to accelerate degenerative changes in the over-burdened joints. The sacral base angle is also important when determining the extent of work needed on a patient. Regardless of the location of the spinal condition a patient is suffering with, the sacral base angle will play an important role in insuring maximum recovery for the patient. If this angle doesn't become part of the initial examination, it's impossible to know what the accurate prognosis and recommendations should be. Thirdly, it's critically important to collect data for the verification of the benefits of chiropractic care, and this measurement provides a solid reference point to measure benefits of treatment. If an abnormal sacral base angle can be found on the initial exam and the patient is put through a corrective treatment/conditioning program and improvements can be seen on re-x-rays, that becomes powerful evidence-based protocols that will get the attention of the medical community. And if this protocol can be duplicated and shown to be directly associated with pain relief and improved capacity, then chiropractic will have a much stronger stance in the medical community, as well as with the eyes of the general public.
What is the angle of the sacrum on a standing x-ray?
This is the angle formed with a line drawn along the top of the sacrum and intersecting with another line parallel to the ground (Fig. 1). A normal sacral base angle is 36°-42°. Of course, this should only be measured when the subject is x-rayed in the standing position with shoes off.
What are the factors that affect the sacral base angle?
The most influencing factors affecting the sacral base angle are heredity, prior injuries, poor conditioning, foot imbalances, leg length differences, weight problems, bad habits, poor posture, job, mattress, shoe style and quality, diet and frequency of getting adjusted. There certainly are many other influencing factors, but from a practical point of view, we must efficiently work with those we know and can improve upon.

Bony Landmarks
- Base
The top part of the sacrum, lying just below the spinal base, is referred to as the base of the scarum. It is the widest portion of the bone. The first one of the five fused sacral vertebrae, S1, is located here. The S1 vertebra is the biggest one, having concave superior articular facets that pr… - Apex
It is the pointy part of the sacrum, directing downwards. The fifth sacral vertebra lies in this most inferior segment of the bone. The apex projects posteriorly to increase the size of the pelvic cavity. This region features an oval facet for articulation with the coccyx.
Articulations
- Lumbosacral joint: The base of the sacrum articulates with the fifth lumbar vertebrae (L5) superiorly via the L5/S1 intervertebral disc, forming this amphiarthrodial joint.
- Sacrococcygeal joint: Here, the apex of the bone articulates with the base of the coccyx, to form another amphiarthrodial joint.
- Sacroiliac joint: The sacral ala laterally articulates with the ilium of the pelvis, forming this sy…
