Active rib metabolism one month after surgery suggests that the local tissue cells are active in proliferation, and the causes of the corresponding condition include metastasis, rib fracture and local inflammatory reaction. 1. Metastatic tumor: if you have had a malignant tumor surgically removed and find active rib metabolism one month later, you need to consider the possibility of metastatic tumor, and the active proliferation of tumor cells will cause corresponding changes. 2. Rib fracture: when rib fracture occurs during or after surgery, cell proliferation is active in the process of repairing the fracture, which will also cause metabolically active performance. 3. Local inflammation: local infection after periprosthetic surgery may lead to inflammatory reaction, and local inflammatory cell infiltration may also cause related manifestations. If the metabolism of ribs is active one month after the surgery, and accompanied by bone destruction, and the symptoms continue to aggravate, it is necessary to consult a doctor in time for examination, and carry out standardized treatment under the guidance of the clinician after the diagnosis of the disease, so as to avoid the delay of the disease.
