Backbone

Introduction The palm and phalanx tuberculosis of the hand is the infection of the Mycobacterium tuberculosis into the palm and the medullary cavity. The medullary cavity is inflated due to destruction of the osteolytic bone, and the bone is thinned and expanded. Invasion of tuberculous granulation tissue to the subperiosteal resulted in the formation of a capsule and the separation of bone necrosis. In adults, the infection is mainly under the periosteum, which causes the blood supply to the bones to be blocked early, the bone necrosis is separated or pathological fractures occur, and the fingers are shortened. The disease is more common, the patient is mostly children under 10 years old, and is multiple. Early application of anti-tuberculosis drugs and finger fixation in the early stage of the disease (strong healing of bone lesions, generally non-surgical treatment) is effective.

Cause

The disease is mainly caused by infection of primary sources such as tuberculosis. The palm and phalanx tuberculosis of the hand is the infection of the Mycobacterium tuberculosis into the palm and the medullary cavity. The medullary cavity is inflated due to destruction of the osteolytic bone, and the bone is thinned and expanded. Invasion of tuberculous granulation tissue to the subperiosteal resulted in the formation of a capsule and the separation of bone necrosis.

3. X-ray film shows: the bones of the affected finger are damaged.

Differential diagnosis

Feelings of hands and fingers: The condylar chest muscle syndrome will have full feeling of hands and fingers, and the forearms and fingers have numbness and tingling.

Finger pain or tenderness: It is a clinical manifestation of peripheral neuropathy syndrome or enteric dermatitis. Toe pain, abnormal limbs, poor coordination of legs and feet, fingertip pain or tenderness, hyperalgesia/limited limb pain, leg pain, hyperactive legs, feeling dull, paresthesia, numb fingers.
