The eventual fusion of its five vertebrae into one solid bone is a key developmental milestone, offering a precise answer to the question: **At what age is the sacrum fused?**

What Age Do Vertebrae Fuse? A Detailed Look at Spinal Development

The human spine begins as separate, flexible structures and undergoes a complex ossification process that continues for decades. Understanding at what age do vertebrae fuse is key to grasping the full timeline of skeletal maturation, as this process varies significantly across different regions of the spine and is not complete until early adulthood.

At what age are all segments of the sacrum united?

The sacrum, a triangular bone at the base of the spine, is initially composed of five separate vertebrae in children. A gradual process of bony fusion occurs during adolescence and early adulthood, ultimately resulting in one solid bone. The specific age at which all segments of the sacrum are united varies among individuals but is typically complete by the late twenties to early thirties.
