An ultrasound scan is an imaging procedure that uses high-frequency sound waves to produce pictures of the inside of the body. Ultrasound-guided hip joint injections are used to diagnose the underlying cause and relieve hip pain. The injection consists of a special mixture of an anesthetic and a steroid that blocks pain impulses and reduces inflammation in the injected area.
The hip joint helps to bear your body’s weight while standing, walking and running. The joint may become painful and inflamed due to overuse, trauma or certain medical conditions such as osteoarthritis, leading to pain in the hip, low back, buttock or leg. The pain may increase with certain activities and movements.
The hip joint is a ball and socket joint and is the largest weight-bearing joint in the human body. The head of the thigh bone or femur forms the “ball” and the acetabulum of the pelvis is the “socket”. These bones come together to form the hip joint.

You are advised not to drive, bathe or shower immediately after the procedure. The anesthetic in the injection usually has an immediate effect. The steroid component will start to show effects in 2-3 days.
Ultrasound-guided hip injections provide an effective treatment for hip pain and inflammation when medications and other conservative treatments are inadequate and surgery is not recommended. You may resume normal activities the day after the procedure as advised by your doctor. The procedure is minimally invasive, does not involve radiation and may be repeated up to 3 times a year.
Risks and complications with this procedure are rare and include:
