Synovitis of the hip joint is usually cured in one to two weeks with regular conservative treatment. Synovitis of the hip joint in clinical practice can be divided into children and adults. Synovitis of the hip joint in children is also known as transient synovitis of the hip joint, which is usually caused by the inflammation of the synovial membrane of the hip joint due to excessive activity in children, which results in hip joint pain and restricted movement, especially with the dysfunction of external rotation and abduction of the hip joint, which can induce pain when walking. In this case, traction is usually applied to the affected limb for a week or so, and the weight of the traction is maintained at 1-2 kg, so that normal activities can be resumed after the inflammation has subsided, but attention should be paid to reducing the amount of activity during this period. For adults with synovitis of the hip joint, medication is usually recommended, usually oral non-steroidal anti-inflammatory and analgesic drugs are used for symptomatic treatment, which can be combined with local physical therapy such as hot compresses.
