Bone Tuberculosis: Symptoms, Causes, and Treatment Options

Bone tuberculosis, sometimes called skeletal tuberculosis or osteoarticular tuberculosis, is an uncommon form of tuberculosis that affects the bones and joints. Unlike pulmonary tuberculosis, which affects predominantly the lungs, bone tuberculosis develops when the infection spreads from the lungs to other regions of the body via the bloodstream or lymphatic system.

What are Bone Tuberculosis Symptoms?

Diagnosing bone tuberculosis in its early stages might be difficult, because symptoms may not present until infection has progressed significantly. Some common symptoms include:

• Severe back pain
• Inflammation in the back or joints
• Stiffness
• Difficulty moving or walking, especially in children
• Spinal abscess
• Soft tissue swelling
• Neurological disorders
• Tuberculosis-related meningitis
• Muscle weakness
• Paralysis, such as paraplegia or tetraplegia
• Kyphosis, or hunchback
• Bone or spinal deformities

Causes and Risk Factors of Bone Tuberculosis

The primary cause of bone tuberculosis is the bacterium Mycobacterium tuberculosis, which also causes pulmonary tuberculosis. The infection can spread to the bones through the bloodstream or lymphatic system, typically affecting the spine, hip, and knee joints.

Factors that raise the chance of acquiring bone tuberculosis include:

• Individuals with HIV/AIDS have weakened immune systems.
• Malnutrition
• Diabetes
• Chronic renal failure
• Immunosuppressive therapy

Stages of Bone Tuberculosis

Bone tuberculosis progresses through several stages:

• Early stage: The infection begins in the bone or joint, causing inflammation and destruction of the affected area.
• Late stage: As the infection progresses, it can lead to the formation of abscesses, fistulas, and bone deformities.
• Healing stage: With proper treatment, the infection can be controlled, and the affected area may begin to heal, although some deformities may persist.

Spread of Bone Tuberculosis

Unlike pulmonary tuberculosis, which can spread through the air, bone tuberculosis is not contagious unless an individual comes into contact with the pus or infected fluid from a patient. However, it is essential to note that bone tuberculosis can develop as a result of an untreated pulmonary tuberculosis infection.

Diagnosis and Bone Tuberculosis Treatment

Diagnosing bone tuberculosis requires a combination of tests and examinations, including

• Bacterial culture
• Biopsy
• Body fluid tests
• PCR tests
• Immunological tests
• Radiological imaging

Bone tuberculosis is normally treated with a mix of medicines and, in some circumstances, surgery. Treatment might last anywhere from 6 to 18 months, depending on the severity of the illness and the patient's reaction. Commonly prescribed medications include rifampicin, isoniazid, ethambutol, and pyrazinamide.

In cases of advanced bone tuberculosis, surgical intervention may be necessary to remove infected tissue, repair damaged bones, or relieve pressure on the spinal cord.

Conclusion

Bone tuberculosis is a dangerous disease that requires immediate diagnosis and treatment. Understanding the symptoms, causes, and risk factors related to this disease, individuals can seek medical attention early and reduce the risk of complications. With proper management, bone tuberculosis can be effectively treated, and its long-term effects can be minimized.
