Discitis and Vertebral Osteomyelitis

What is this condition?

Discitis and vertebral osteomyelitis are infections of the disc space and adjacent bone, commonly bacterial but sometimes tuberculous or fungal. Infection may arrive through blood, after a procedure or from nearby tissue. Diabetes, immune suppression, dialysis, intravenous drug use and recent infection increase risk, but anyone can be affected.

What symptoms can it cause?

• Severe persistent focal back or neck pain
• Fever may be present but is not universal
• Pain at rest/night and difficulty moving
• Epidural abscess can cause weakness, numbness or bladder/bowel change

How is it assessed and diagnosed?

MRI with contrast is the preferred imaging; CT shows bone and guides biopsy. Blood cultures should be taken before antibiotics when the patient is stable. ESR/CRP track inflammation. Image-guided biopsy or surgery provides organism and pathology, especially when blood cultures are negative or TB, fungus or tumour is possible.

Treatment without surgery

Many stable patients receive culture-directed antimicrobial treatment for a prolonged period, with pain control and selected bracing. Source control may include treating infected urine, skin, heart valve or line. Empirical antibiotics are started immediately when sepsis or neurological compromise makes waiting unsafe.

When is surgery or a procedure considered?

Surgery is considered for neurological deficit, epidural abscess with compression, sepsis despite treatment, instability, deformity, severe unrelenting pain, uncertain diagnosis or failure of suitable antibiotics. It may include drainage, debridement, decompression and stabilisation.

Treatment and procedure options

• Culture-directed antibiotics/antimicrobials
• Image-guided biopsy or abscess drainage
• Surgical decompression and debridement
• Stabilisation when infection has destroyed support
• Rehabilitation and source-control treatment

Risks from the disease and from treatment

Delay can lead to sepsis, paralysis, vertebral collapse and chronic pain. Antibiotic toxicity, resistant organisms and recurrent infection are possible. Surgery in infected, medically unwell patients carries wound and implant risks, but appropriate stabilisation can be necessary for recovery. No procedure is risk-free. General risks include anaesthetic problems, bleeding, infection, blood clots and delayed healing. Neurological risks depend strongly on the exact structure being treated and may include new weakness, numbness, speech or vision change, seizure, cerebrospinal-fluid leakage, need for another procedure or failure to obtain the hoped-for relief. The surgeon should discuss the risks that apply to the individual case.

Recovery and follow-up

Pain and blood markers are followed over weeks. Repeat MRI is chosen when progress is poor or neurology changes, not automatically every few days. Completing therapy, controlling diabetes and gradual mobilisation reduce relapse and deconditioning. Recovery is not judged only by the first few days. Pain control, wound care, nutrition, safe mobilisation, physiotherapy and planned follow-up all matter. Some symptoms improve quickly after pressure is relieved; others recover gradually over weeks or months, and permanent nerve injury may not fully reverse.

Preparing for your consultation

Bring the original MRI/CT images or digital files, written reports, previous prescriptions, a current medicine list, and any operative or pathology records. For sudden warning symptoms, use the nearest emergency department rather than waiting for a routine appointment.
