Snapping hip is clinically known as snapping hip, which may be caused by physiological reasons such as long-term strain, cold stimulation, or pathological factors such as osteoarthritis and trauma. 1. Physiological causes: Snapping hip is also known as iliotibial bundle friction syndrome. Long-term strain or long-term cold stimulation of the hip joint can lead to contracture of soft tissues such as the broad fascia tensor or gluteus medius muscle, and when the hip joint moves, these soft tissues rub against the greater trochanter of the femur, resulting in a popping sound. Symptoms are aggravated when the hip joint is flexed and extended, and can be relieved when resting. 2. Pathological causes: osteoarthritis of the hip joint can lead to the formation of bone cumbersomening inside the joint, the tension of the soft tissues around the hip joint, the change of the joint space, etc. When the joint is moving, the impact or friction between the soft tissues and the bone may also lead to the snapping sound of the hip joint; trauma of the hip joint can lead to the abnormality of the internal structure of the hip joint, which may also lead to the above mentioned symptoms, such as dislocation of the hip joint, glenoid labrum injury, etc. . There may also be other reasons for the ringing of the hip bone, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or treatment under the guidance of the doctor.
