1B12.4Y/A18 Tuberculosis of other specified part of the musculoskeletal system



Tuberculosis of other specified parts of the musculoskeletal system is caused by the Mycobacterium tuberculosis (MTB) bacteria. It is typically spread through the air when an infected person coughs, sneezes, or speaks. It can also be spread through contact with an infected person’s saliva, sputum, or other body fluids.


Diagnosis of this condition is usually done through a combination of physical examinations, laboratory tests, and imaging techniques such as X-rays, CT scans, or MRI scans. A sample of the affected tissue may also be taken for further testing.

Differential diagnosis

Other conditions that may need to be considered in the differential diagnosis include osteomyelitis, rheumatoid arthritis, and septic arthritis.


Treatment typically includes a combination of antibiotics, anti-inflammatory medications, and rest. Surgery may also be necessary if the infection has spread to the bone or if there is a risk of joint destruction.


Prognosis depends on the extent of the infection, the patient’s age, and the overall health of the patient. Early diagnosis and prompt treatment increase the chances for a successful outcome.
