A snapping hip is an abnormal ringing sound when the hip joint is extended and flexed or when walking. It is often due to hypertrophy of the iliotibial bundle in the hip or the patient is tense or has bursitis, causing the symptom of snapping when the hip joint moves. If the snapping hip does not affect the function of the hip joint and the patient does not experience pain, no treatment is required and only observation is needed. If the ringing is obvious and affects the movement of the joint, oral medication as well as physical therapy and closure therapy can be administered, and the rheumatoid factor and HLA-B27 can be checked to rule out other diseases. In severe cases, if conservative treatment is not effective, surgery can be performed to cut off the hyperplastic cords under local anesthesia, which can make the symptoms of the snapping hip disappear, and in some cases, iliotibial lengthening can be performed to maintain the stability of the joint and eliminate the snapping symptoms.
