What should you know about vertebral osteomyelitis and discitis?

Osteomyelitis describes infection in a vertebral bone; discitis describes infection in the disc space between vertebrae. They can occur together because these structures are close. Persistent back or neck pain, stiffness, tenderness, fever, chills, or reduced energy may develop. Symptoms can be subtle, especially in older adults or people whose immune system is weakened.

Clinicians may use blood tests and spinal imaging to look for inflammation, changes in bone or disc, collections of infected fluid, or pressure near nerves. Blood cultures or a guided sample can help select treatment. The team also assesses spinal alignment and nerve function.

Treatment is directed at the infection and may include antimicrobial medicine, pain relief, activity modification, and sometimes a brace. The course is reviewed using symptoms, examination, blood results, and imaging when needed. Surgery may be required for spinal instability, a collection that needs drainage, nerve compression, or damaged tissue. If reconstruction is necessary, bone grafting can be part of the surgical plan. Rehabilitation is introduced gradually after the spine is considered stable.

Get urgent medical help for new weakness, worsening numbness, difficulty walking, loss of bladder or bowel control, severe rapidly worsening pain, fainting, confusion, or fever with shaking chills. New nerve symptoms can indicate pressure around the spinal cord or nerve roots.

Ask whether both bone and disc are involved, which test will confirm the diagnosis, and whether a sample is needed. Clarify medicine timing, activity and brace guidance, follow-up tests, expected rehabilitation steps, and which symptoms should prompt an immediate call.
