Bone infarction
Bone infarction is acute ischemia of a part of bone tissue caused by a disruption of the blood supply to this area.
Causes
The main cause of bone infarction is thrombosis of the vessels that supply bone tissue. Risk factors include atherosclerosis, trauma, tumors, and inflammatory diseases. Infarction most often occurs in the area of the femur and tibia.
Symptoms
The leading symptom is sudden severe pain in the affected area. Swelling of soft tissues and skin hyperemia are noted. On palpation - local pain and increased local temperature.
Diagnostics
The diagnosis is confirmed by X-ray, CT, and MRI data. Signs of bone marrow edema and bone destruction are detected.
Treatment
Treatment includes pain relief and restoration of blood circulation in the affected area. If conservative therapy is ineffective, surgery may be required.
Forecast
With timely treatment, the prognosis is favorable. Complete restoration of bone tissue occurs within several months.
