How is tuberculosis of metacarpal and phalangeal bone caused?

summary

Phalangeal tuberculosis and metacarpal tuberculosis are commonly referred to as the backbone tuberculosis of the short bones, the incidence rate is the secondary position of the upper limb bone and joint tuberculosis, only below the elbow joint tuberculosis, accounting for 4.88% of the total bone and joint tuberculosis. Most of the patients were children, but rarely adults. The most common sites were metacarpal bone, proximal phalanx, middle phalanx, and distal phalanx. How is tuberculosis of metacarpal and phalangeal bone caused? Next, I'd like to share my views with you.

How is tuberculosis of metacarpal and phalangeal bone caused?

First, the pathological changes of diaphyseal tuberculosis are mainly hyperplasia, followed by osteolytic destruction, and dead bone formation is rare. Tuberculosis of the short bone shaft of the hand is also characterized by hyperplasia, sometimes dead bone formation can be seen, and its pathological changes are slightly different from those of the long bone shaft. The common changes are air heave, that is, bone swelling and thinning, medullary cavity expanding due to osteolytic destruction, dead bone formation is more than that of tuberculosis of the long bone shaft, which may be due to small bone body,

Second, the chance of joint involvement is more than long bone tuberculosis; The incidence rate of short tubular tuberculosis is much higher than that of long bones. The reason is that the muscles around the short bone are small or absent, and lack of muscle protection.

Third: the nutrient vessels of the short tubular bone are thin, the blood flow velocity is slow, and the bacterial embolus is easy to stay in the local area. In the metacarpal and phalangeal tuberculosis of the hand, the number of cases of metacarpal bone is higher than that of phalangeal bone, and the distal phalangeal bone is rare. Among the five fingers, the prevalence of metacarpal bone and phalangeal bone of 1, 2 and 3 fingers is higher, and that of metacarpal bone and phalangeal bone of 4 and 5 fingers is lower.

matters needing attention

Usually need to pay more attention to nutrition. The cure rate of backbone tuberculosis is high, and non-surgical treatment can be used generally. Pay attention to diet, do not eat spicy food, light food is appropriate, often eat a lot of fresh fruits, vegetables, raw nuts, plant seeds, soybean products and whole grain food, to meet the body's needs for a variety of nutrients.
