Which bone is most commonly affected by tuberculosis?

Bone tuberculosis is simply a form of TB that affects the spine, the long bones, and the joints. In the United States, only about 3 percent of all TB cases affect the musculoskeletal system. Of those cases, the spine is most commonly affected.

How does TB affect the bones?

Skeletal tuberculosis can also be caused by pulmonary tuberculosis. Mycobacteria can easily spread from your lungs to your bones, spine, or joints through blood vessels. This can affect your long bones or spinal vertebrae.

What causes tuberculous osteomyelitis?

Tuberculous osteomyelitis occurs secondary to lymphohematogenous spread of Mycobacterium tuberculosis from a pulmonary focus [5]. Clinical symptoms are very nonspecific and can include insidious onset of pain, swelling, decreased range of motion and difficulty ambulating.

What is tuberculous osteomyelitis?

Tuberculous osteomyelitis is an uncommon infection that usually involves the vertebrae. An otherwise healthy young man with a chronic discharging sinus on his right foot caused by tuberculous osteomyelitis is described.

Can bone TB reoccur?

Bone TB is a chronic disease, which is difficult to treat and easy to recur, and its morbidity has increased in the past 10 years [7,8]. Drugs and surgery are the main treatments for bone TB. A certain recurrence rate occurs after surgery.

Can spine TB reoccur?

Complex spinal tuberculosis is characterized by a long disease course, severe disease conditions, and complex and various clinical manifestations; in addition, the clinical treatments for this disease are generally tricky, and the postoperative recurrence rate is relatively high.

Can bone TB cause osteomyelitis?

It may be confused with Brodie’s abscess due to similar clinical, radiological and laboratory findings. Late diagnosis of the disease causes bone destruction. Tuberculosis osteomyelitis of the bone is a rare condition caused by the Mycobacterium tuberculosis.

Can TB affect feet?

Tuberculosis of the foot and ankle is an uncommon presentation of skeletal tuberculosis. The uncommon site, lack of awareness, and ability to mimic other disorders clinically and on radiographs, leads to diagnostic and therapeutic delays.

Is bone TB completely curable?

The major sites affected in bone tb are spine and weight bearing joints. It is a serious condition since it destroys the thoracic and leads to bone deformity. It is extremely important to detect bone tb symptoms as soon as possible. Bone tb is a curable condition if detected soon.

Can TB come back after 10 years?

The relapse rate differs by a country’s incidence and control: 0–27% of TB relapses occur within 2 years after treatment completion and most relapses occur within 5 years; however, some relapses occur 15 years after treatment.

Can a person get TB twice?

Even if you successfully beat tuberculosis, you can get tuberculosis infection again. In fact, TB reinfection is becoming more common. Tuberculosis is a potentially life-threatening, airborne bacterial infection that can be found worldwide.

What is syphilitic osteomyelitis?

Syphilitic osteomyelitis of the skull is a destructive bone disease that occurs as a complication of syphilis; however, it is an unusual complication of early stage (primary or secondary) syphilis9,10,14).

What are well-defined osteolytic bone tumors and tumor like lesions?

In this article we will discuss the differential diagnosis of well-defined osteolytic bone tumors and tumor-like lesions. On the left the most common well-defined bone tumors and tumor-like lesions. These lesions are sometimes referred to as benign cystic lesions, which is a misnomer since most of them are not cystic, except for SBC and ABC.

What is osteolytic lesion of the skull?

Osteolytic lesion arising from the neurocranium with associated soft tissue swelling. Mixed lytic-sclerotic lesion, not well-defined with solid periosteal reaction. Sharply defined osteolytic lesion of the skull.

What is the best mnemonic for osteolytic bone lesions?

Well-defined osteolytic bone tumors and tumor-like lesions have a plethora of differentials in different age groups. For simplicity, a widely used mnemonic for lytic bone lesions is extremely helpful: FEGNOMASHIC. We have attempted to describe the most characteristic features of each of these tumors.

What is cortical destruction in a bone lesion?

Cortical destruction: Cortical destruction is a frequent finding in bone lesions. However, it is not very useful in differentiating benign versus malignant lesions. Complete cortical destruction may be present in high-grade malignant lesions like osteosarcoma, Ewing sarcoma, and also in locally aggressive benign lesions.
