Osteoarthritis of the hip bone can be diagnosed by a combination of clinical symptoms, imaging tests, and blood tests. 1. Clinical symptoms: Most patients with osteoarthritis of the hip bone may experience pain in the hip joint area for more than a month. It is also accompanied by internal rotation deformity of the hip joint, snapping sound, limitation of hip joint movement, swelling of the hip joint, intra-articular fluid accumulation, etc. In severe cases, patients may be unable to stand or walk and need to stay in bed for a long period of time. 2. Imaging examination: Through imaging examination, the X-ray film of patients with osteoarthritis of the hip bone will show acetabular rim hyperplasia or narrowing of the hip joint space, formation of bone capillaries at the edge of the joint, uneven surface of the articular surface, sclerosis of the subchondral bone and formation of the capsule cavity, and when accompanied by synovitis, the fat pads will be obviously blurred or disappeared. 3. Blood test: patients with osteoarthritis of the hip bone, due to the inflammatory state, by blood test, the content of immunoglobulin and fibrinogen increases, which usually leads to accelerated sedimentation rate of blood cells. Therefore, one of the ways to diagnose osteoarthritis of the hip bone is that the patient’s hematocrit is less than or equal to 20mm/1h.
