The projecting anterior edge of the body of the first sacral vertebra is called the sacral promontory etc
The end of the sacrum is your trail bone. I have fusions there.
The inferior end of the sacrum is composed of the coccyx, which is a small triangular bone formed by the fusion of 3-5 vertebrae. The coccyx serves as an attachment site for ligaments and muscles and helps support the pelvis when sitting.

The sacrum and coccyx lie inferior to the lumbar vertebrae in the vertebral column.
The superior articular process of the sacrum articulates with the inferior articular process of the last lumbar vertebra (L5) to form the lumbosacral joint.

A .07 sclertoic lesion on my scarum which they say is stable. However, I have severe pain in that area and in my lower back and right leg. I have trouble walking or standing what does this mean.
The sacrum has a base, an apex, and three surfaces: a pelvic, dorsal and a lateral surface.
