caries

Japanese: カリエス

The term means "bone rotting" and refers to the collapse of bone tissue caused by caseous necrosis. As the majority of cases are caused by secondary infection in tuberculosis, caries is nowadays understood to be synonymous with bone tuberculosis. Depending on the part of the body affected, it is called spinal caries, rib caries, pelvic caries, etc., but the spine and ribs are most often affected. As with spinal caries, most cases of caries are caused by tuberculosis bacteria being carried to the bone marrow via the bloodstream from tuberculous lesions such as the lungs. However, in rib caries, the lesions spread from the lungs by contagion. Treatment is primarily systemic therapy, i.e. rest, nutrition, and chemotherapy, followed by immobilization of the affected area and surgery.

Japanese:

〈骨が腐る〉という意味で，乾酪性壊死(えし)による骨質の崩壊現象をいう。原因は結核における二次感染によるものが大部分なので，今日ではカリエスは骨結核と同義に解されている。冒される部位により脊椎カリエス，肋骨カリエス，骨盤カリエスなどと呼ばれるが，脊椎と肋骨が冒されることが最も多い。カリエスの大部分は，脊椎カリエスのように，肺などの結核病巣から血行的に結核菌が骨髄に運ばれることによる。しかし肋骨カリエスでは，肺から伝播的に病巣が広がっていく。治療は，全身療法すなわち安静・栄養・化学療法が第一で，さらに病患部の固定，手術を行う。
