No, lumbar vertebrae are not fused; they are typically separate and consist of five individual vertebrae (L1 to L5) in the lower back. This arrangement allows for flexibility and a range of motion, which is essential for activities such as bending and twisting. In some cases, individuals may experience conditions that lead to fusion, but under normal circumstances, these vertebrae remain distinct.

Transitional lumbosacral vertebra is a condition where the last lumbar vertebra (L5) is partially fused with the first sacral vertebra (S1).

What is the medical term meaning lumbar?
"Lumbar" refers to the region of the back or spine made up of the lumbar vertebrae. The 1st lumbar vertebra is just under the 12th thoracic vertebra. The easiest way to find this is to find the first vertebral body not connected to a rib. This is L1 (1st lumbar vertebra). There are 5 lumbar vertebrae (L1 through L5). The 5th lumbar vertebra sits on top of the sacrum (where your spine connects with your pelvis).
