Hip injection therapy refers to a medication or combination of medications that can be injected into the hip joint. The hip joint itself is composed of the top of the femur, or femoral head and the socket of the pelvis, or acetabulum. The joint is surrounded by a capsule, or balloon-like structure, that keeps the environment lubricated. Structures such as cartilage, the labrum subchondral bone all reside inside of the joint. The hip bursa and tendons attaching to the hip region reside outside of the capsule. Medications are then directed into the joint through the use of a needle, which can be introduced using image-guided technology.
The hip joint is a deep-seated joint that can be difficult to access successfully without image guidance. Generally, a procedure is required where the patient has an x-ray image obtained using the fluoroscopy machine and the position of the hip is marked. A needle may then be introduced and dye injected into the joint to confirm appropriate positioning. Another method that is routinely used is ultrasound guidance.
A cortisone, or steroid injection, is one of the most common hip injections available to treat a variety of maladies affecting the hip. This usually contains a combination of anesthetic medicine in addition to the steroid, which may take some time to achieve a therapeutic effect.
