Spinal Tuberculosis (Pott’s Disease): Symptoms, Treatment, Diagnosis & More 

Introduction

Persistent back pain and neck stiffness are often blamed on muscle strain or poor posture in most of the cases, while sometimes these won’t be the real cause. Spinal tuberculosis, which is also known as Pott’s disease, is a condition which affects the spine. If left untreated, it can cause spinal abnormalities and other complications¹. This blog will help in understanding the symptoms, causes, diagnosis, treatment options, and methods for managing Pott’s disease for better spinal health. 

What Is Spinal Tuberculosis (Pott’s Disease)?

Spinal tuberculosis, also known as Pott’s disease, is a type of tuberculosis (TB) that affects the bones and disc of the spine¹. It occurs when TB-causing bacteria travel from the lungs or another region of the body to the spine². There are different stages of spinal tuberculosis; starting from early infection of spinal bone (vertebrae) that can spread to the surrounding tissues (intervertebral spaces) causing discomfort, pain and difficulty moving to significant destruction of vertebral bone causing structural abnormalities. In severe cases, it can affect the nerves, causing weakness or numbness³. Early diagnosis and treatment can help to avoid serious problems and protect spinal health¹. 

Symptoms of Pott’s Disease

Spinal TB can cause mild to severe symptoms. The following are some of the spinal tuberculosis symptoms: 

• Unexplained or persistent back pain that does not reduce with rest²
• Difficulty moving due to stiffness of back⁴ 
• Numbness or tingling sensation in legs¹
• Loss of control over passing urine or stool¹
• Muscle spasm⁴
• Difficulty in walking due to pain¹
• Spinal deformities such as painless lumps filled with pus (cold abscess), pus-filled swelling (gibbus), or hunchback (kyphosis)⁴ (in severe cases) 

These symptoms usually occur along with other constitutional tuberculosis symptoms that include: 

• Fever, especially a mild increase in body temperature that usually occurs in the late afternoon or evening (known as evening fever)²
• Excessive sweat at night while sleeping⁴
• Chronic fatigue 
• Loss of appetite and unexplained weight loss⁴

Causes of Pott’s Disease

Pott’s disease is caused when the Mycobacterium tuberculosis bacteria spreads from the main site of infection to the spine⁴. In most cases, the bacteria are inhaled and infect the lungs, resulting in pulmonary tuberculosis⁵. From the lungs, the infection can then spread to the spine through the bloodstream.  

In some cases, the bacteria may spread through blood from primary genitourinary infections also to reach the spine. 

Once the bacteria reach the spine, they settle in the vertebrae, multiply, slowly infiltrate surrounding soft tissue and cause bone damage⁴.

Risk Factors for Pott’s Disease

Although spinal tuberculosis causes are usually linked to the spread of infection from the lungs or other parts of the body, there are certain factors that can increase the risk of infection spreading to the spine. These include: 

• History of Tuberculosis: People who already have or had TB (especially lung TB) are more likely to develop spinal TB⁶.
• Weakened Immune System: Immunosuppressive conditions weaken the body’s ability to fight TB infection. This includes illnesses like HIV/AIDS, poor nutrition, diabetes, kidney disease, cancer treatment, drug abuse, alcohol use, etc^2,7,8.
• Poverty: Poor living conditions can make people more prone to spinal TB².
• Vitamin D Deficiency: Low vitamin D levels can also contribute to spinal TB and spinal bone loss⁷.
• Delayed Diagnosis: Delayed diagnosis and treatment can also increase the risk of getting spinal TB, especially in the elderly and people with poor nutrition⁷.

Complications of Pott’s Disease

If Pott’s disease treatments are delayed, it can lead to several serious complications affecting the spine and nervous system. 

• Spinal Deformity: Abnormal forward bending or hunching of the back due to damage of spinal bones (kyphosis)².
• Spinal Instability: The spine becomes weak and unable to stay properly aligned, leading to abnormal movement and pain².
• Chronic Back Pain⁶: Long-lasting pain caused by infection and structural damage to the spine. 
• Nerve Compression: Pressure on spinal nerves leading to pain, weakness, or numbness in the legs².
• Cauda-Equina Syndrome: Difficulty controlling urine or stool due to nerve involvement^1,4. 
• Permanent Disability¹: Severe or untreated cases may result in long-term physical disability. 
• Paralysis: Severe cases may lead to partial or complete loss of movement in the lower limbs¹.

Diagnosis of Pott’s Disease

Spinal tuberculosis diagnosis includes a combination of clinical evaluation and medical tests. The tests doctors usually perform include: 

• Physical Examination: The doctor checks for symptoms such as back pain, stiffness, weakness, and visible spinal deformity^1,2,4.
• Blood Tests: He might suggest tests such as: 
  • Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP): Detects inflammation in the body, which may suggest an ongoing infection like TB².
  • Interferon-Gamma Release Assay (IGRA): Detects TB infection by measuring the immune system’s response to TB bacteria in the blood².
  • Mantoux Test: Checks for TB exposure by observing a skin reaction after injecting a small amount of TB antigen⁹.
• Sputum Test^5,9: The doctor might suggest testing sputum, which might help detect TB bacteria in mucus produced from the lungs. It is mainly used to confirm active pulmonary TB. 
• Imaging Tests: The doctor might also suggest some imaging tests. These include: 
  • X-Ray: Helps show changes in the spine, such as bone damage, narrowing of disc space, or deformities in advanced cases. 
  • Magnetic Resonance Imaging (MRI) Scan: Gives detailed views of the soft tissues, spinal bones, and nerves, allowing for detection and spread of infection to the nearby areas, pus-filled swelling, spinal cord compression and disc and bone damage.
  • Computed Tomography: Helps detect infection-related changes in the spine, such as pus-filled swellings, bone destruction, and pressure on the spinal cord, as well as assist tissue sample collection for diagnostic purposes⁴.
• Biopsy: The doctor might perform a biopsy, in which a small sample of tissue from the affected area might be collected and examined to confirm the diagnosis of spinal tuberculosis. The sample is then sent to the laboratory to confirm the presence of the bacteria using tests such as AFB culture, which can help detect active tuberculosis infection and support accurate treatment planning².

Treatment of Pott’s Disease

The goal of spinal tuberculosis treatment is to control the TB infection, alleviate symptoms, and avoid consequences like spinal injury and nerve involvement. The following are the usual treatment approaches recommended by the doctors: 

1. Anti-Tuberculosis (TB) Medication

This is the primary treatment for Pott’s disease. These drugs aid in the elimination of tuberculosis bacteria, stopping the spread of the infection, and preventing further spine damage. The treatment usually includes a combination of TB medicines (rifampin, isoniazid, ethambutol and pyrazinamide) for several months, with treatment typically lasting between 6 and 18 months depending on the condition¹⁰.

2. Pain and Supportive Management

Supportive measures such as adequate rest, wearing a body cast or using plaster beds, and maintaining good nutrition can help support healing and reduce stress on the affected spine^10,11. Once the infection is under control, physical therapy may be recommended to improve strength, flexibility, mobility, and overall spinal function¹.

3. Surgical Management

Surgeries may be recommended for the severe cases of spinal instability, major spinal deformity, massive abscesses, or spinal cord compression. It can assist to remove contaminated tissue, reduce nerve strain, and stabilise the spine¹⁰.

Prevention of Pott’s Disease

The following are some ways by which Pott’s disease can be prevented: 

• Timely treatment for lung or other tuberculosis infections helps to keep the bacteria from spreading to the spine. 
• Maintaining a healthy immune system through proper nutrition and exercise helps the body fight infections².
• Early screening helps diagnose tuberculosis at an early stage, particularly in high-risk individuals⁴.
• Covering the mouth while coughing and maintaining cleanliness helps reduce the spread of TB bacteria to others (this in turn can reduce the chances of spinal TB)¹².
• Proper management of diseases like HIV or diabetes that suppress the immune system and facilitate bacterial spreading². 
• Taking preventive vaccines, such as Bacillus Calmette-Guerin (BCG), helps protect against severe forms of tuberculosis, especially in children^5,8, and can reduce the risk of complications like Pott’s disease. 

When to See a Doctor?

Consult a doctor for symptoms like prolonged back pain that does not improve with therapy, and especially if it is accompanied by fever, night sweats, unexplained weight loss, or increased weakness or numbness in your legs or arms^2,4. Difficulty walking or any loss of bladder or bowel control should be treated as emergency warning symptoms¹. Early medical intervention is critical for swiftly diagnosing the condition and avoiding major problems involving the spine and nerves.
