A Growing but Overlooked Spinal Threat
India carries the world’s highest burden of tuberculosis, accounting for nearly 26% of all global TB cases according to the WHO’s 2023 Global TB Report. While most people associate TB with the lungs, spinal tuberculosis — also known as Pott’s disease — is the most common form of skeletal TB, representing 50% of all musculoskeletal TB cases. Despite its prevalence, spinal TB is frequently misdiagnosed, leading to preventable paralysis and long-term disability. Consulting the Best Spine TB Doctor in Delhi and Best Spine TB Specialist in Delhi at the earliest sign of symptoms is essential for a safe and complete recovery.
What Is Spinal Tuberculosis (Pott’s Disease)?
Spinal TB occurs when the Mycobacterium tuberculosis bacterium spreads from its primary site (usually the lungs) through the bloodstream and infects the vertebral bodies. It most commonly affects the lower thoracic and upper lumbar vertebrae. As the infection progresses, it destroys bone tissue, causes vertebral collapse, and can form a cold abscess — a pus collection that can compress the spinal cord, leading to neurological deficits or paralysis if left untreated.
Key Symptoms of Spinal TB
Spinal TB symptoms develop gradually and may include:
- Persistent back pain: Often the earliest symptom, worse at night and at rest — unlike mechanical back pain.
- Fever and night sweats: Classic constitutional TB symptoms.
- Unexplained weight loss: A red flag that something systemic is occurring.
- Spinal deformity (kyphosis): A visible hump or angular deformity of the back as vertebrae collapse.
- Neurological symptoms: Weakness or paralysis of the legs, sensory loss, or loss of bladder/bowel control — indicating spinal cord compression.
How Is Spinal TB Diagnosed?
Accurate diagnosis of spinal TB requires a combination of clinical evaluation and investigations. MRI of the spine is the most sensitive imaging tool, showing characteristic findings like vertebral body destruction, disc space involvement, and paravertebral abscess. Additional investigations include ESR, CRP, Mantoux test, IGRA (Interferon Gamma Release Assay), CBNAAT or GeneXpert for TB DNA detection, and CT-guided biopsy for histopathological confirmation.
Medical Treatment: Anti-TB Therapy
The backbone of spinal TB treatment is anti-tuberculosis therapy (ATT). The standard regimen involves an intensive phase of 4 drugs (Isoniazid, Rifampicin, Pyrazinamide, Ethambutol) for 2 months, followed by a continuation phase of 2 drugs for 10–16 months, depending on disease severity and neurological involvement. Drug-resistant TB (MDR-TB) requires second-line agents and specialist management.
Understanding the relationship between spinal infections and co-existing disc problems — including the types of slip disc — is important for holistic spine care. Learn more at this resource on what is a slip disc and types of slip disc.
When Is Surgery Required for Spinal TB?
Surgery is indicated in specific situations: progressive neurological deterioration, large or compressive abscess, severe spinal instability, failure to respond to ATT, or significant spinal deformity. Surgical options include anterior debridement with bone grafting, posterior instrumented fusion, or combined approaches. The goal is to decompress neural structures, drain infection, and stabilise the spine.
Conclusion
Spinal tuberculosis is a serious but treatable condition. Early detection, appropriate anti-TB therapy, and timely surgical intervention when needed can prevent paralysis and restore quality of life.
