sacrum
The five fused vertebrae with which the hip bones move are collectively known as the sacrum. The sacrum forms the posterior wall of the pelvis and connects the spine to the hip bones, providing stability and support for the body.
The last 4 fused vertebrae in the spine are called the sacrum. The sacrum is a triangular bone located below the lumbar vertebrae and is formed by the fusion of five sacral vertebrae.
The lumbar vertebrae in the lower back is typically five in number and unfused.
The bones below the sacrum are called the coccyx, also known as the tailbone. It is located at the base of the spinal column and consists of three to five fused vertebrae. It serves as an attachment point for muscles and ligaments.

Sacrum
sacrum, it's actually five bones that are fused together.
The human backbone is also called the spine, and it consists of a vertebral column that has many bones. There are seven cervical, twelve thoracic, five lumbar, five fused sacral, and four fused coccygeal bones in an adult. So that makes a total of 33 bones.Read more: How_many_bones_make_up_the_human_backbone
