- Osteitis is inflammation of the bone. For example, patients with what is called the SAPHO syndrome develop osteitis — the O in SAPHO stands for oteitis — and the bone inflammation typically affects the sacroiliac joints (sacroiliitis) and the spine (spondylitis). This leads to pain and stiffness in the back and neck.
