Some of the most common causes of hip osteoarthritis include:
- Joint or bone trauma: When a bone or joint is injured, it could be a fracture or a dislocation, the blood vessels may get damaged. The damage to the blood vessels can interfere with blood circulation to the bones. Inadequate blood circulation to the bone can cause osteonecrosis.
- Fatty deposits in blood vessels: Fatty deposits in the blood vessels can create a blockage that may lead to disrupted blood flow in the femoral heads. It may cause lack of nourishment and may lead the head of the femur to die and collapse.
- Certain diseases: Diseases like caisson disease (diver’s disease or “the bends”), sickle cell disease, myeloproliferative disorders, Gaucher’s disease, systemic lupus erythematosus, Crohn’s disease, arterial embolism, thrombosis and vasculitis can cause osteonecrosis.
