Symptoms of prosthesis infection after joint replacement

summary

Any kind of operation is the most afraid of postoperative because of improper nursing or health did not deal with some of the postoperative infection problems. It's the same with arthroplasty, and it's more likely to be infected because it requires artificial implants. So now let's talk about the symptoms of infection of joint replacement prosthesis.

Symptoms of prosthesis infection after joint replacement

In patients with early infection, the body temperature did not recover but increased 3 days after operation. Joint pain is not only not gradually reduced, but gradually aggravated, there is jumping pain at rest. There is abnormal exudation or secretion in the incision. At this time should be carefully examined, do not easily attributed to fever after lung or urinary tract infection caused by other parts. Do not simply regard incision exudate as fat liquefaction and other common exudates. At the same time, we should also identify whether the infection is located in the superficial tissue, or deep and around the prosthesis.

Most of the patients with advanced infection have left the hospital, and joint swelling, pain and fever may not be serious. Half of the patients had no fever. Staphylococcus epidermidis can cause painless infection, only 10% of patients with increased white blood cell count. ESR elevation is common but not specific. Sometimes the pain is misdiagnosed as prosthetic loosening. The pain of the latter is related to exercise and should be relieved at rest, while the inflammatory pain is not relieved at rest. However, some people think that the main reason for prosthesis loosening is delayed chronic infection.

Early infection, X-ray can be no abnormal performance. Similar to late infection, there may be a translucent zone between bone and bone cement, thinning of cortical margin, lamellar periosteal reaction, and coexistence of increased bone mineral density and translucent zone.

matters needing attention

Artificial joint replacement is not a big problem in surgery. After all, medicine is so developed now. But the most important thing is to ask the family members of patients to do a good job in nursing during the recovery period of operation, so as to avoid the occurrence of infection.
