Hip joint injections involve injecting medicine directly into the hip joint to diagnose the source of pain or treat pain due to conditions such as arthritis, injury or mechanical stress of the hip joint. Hip pain may be experienced in the hip, buttock, leg or low back. The injection contains a combination of a numbing medicine and cortisone (an anti-inflammatory agent). Numbing medicine delivers temporary relief from pain, provided the hip joint is the source of the pain. It thus serves a diagnostic function and helps to confirm or deny whether the joint is the source of pain. Cortisone serves to reduce the inflammation in the joint providing long term pain benefit.
If needed, a relaxation medicine is given to the patient through an IV line. The patient lies face down on an X-ray table. The small area where the injection needs to be given is numbed with an anesthetic. The patient may feel a sting for a few seconds. A small needle is then accurately placed by the doctor into the joint guided by the real-time X-ray images (fluoroscopy). Before injecting the medicine, a contrast dye is injected through this needle into the joint to confirm that the medicine will reach the joint. A combination of anesthetic and anti-inflammatory cortisone is then slowly injected into the joint. The whole procedure usually takes about 30 to 60 minutes.
After the procedure
After the injection, the patient is made to rest for 20 to 30 minutes and is then asked to move the joint, provoking pain. The patient may or may not find a decrease in pain depending on whether the injected joint is the main source of the pain. The patient is also asked to maintain a record of relief in pain during the coming week. Physical therapy may also be recommended. Even when pain relief is significant the patient should increase activities gradually over one to two weeks to avoid reappearance of pain.
Risk and complications
The possible risks of hip injections include: swelling and pain in the joint after the injection, infection, depigmentation of skin, local thinning of the skin and rupture of a tendon.
If the injected hip joint is the source of the pain, the pain may reduce two to five days after the injection. However, if no improvement is found within ten days after the injection further diagnostic tests may be required to ascertain the cause of pain.
Physiotherapy or physical therapy is an exercise program that helps you to improve movement, relieve pain, encourage blood flow for faster healing, and restore your physical function and fitness level. The main aim of physical therapy is to make your daily activities, such as walking, getting in and out of bed, or climbing stairs, easier. It can be prescribed as an individual treatment program or combined with other treatments. Physiotherapy is usually ordered to help you recover after certain surgeries, injuries and long-term health problems such as arthritis.
A physiotherapist will examine your symptoms and daily activities, and make a treatment plan, which primarily focuses on reducing your pain and swelling. The different procedures used by your therapist depend on your specific physical ailment. Physical therapy involves a combination of education, manual therapy, exercises and techniques. Some of the procedures commonly used are:
- Stretching exercises: Surgery, age and conditions, such as arthritis and osteoporosis, can cause inflammation and stiffness in your joints and muscles, and restrict your movement. Physiotherapists guide you step by step to stretch certain areas of your body to restore flexibility, and enhance the movement of joints and muscles.
- Core strengthening and stability exercises: Specific exercises are designed to make the core (pelvis and lower back) strong enough to support the whole body.
- Ice and heat: Applying heat or cold treatment on muscles can stimulate the blood flow and reduce swelling. Heat treatment helps to reduce joint pain and spasm in the lower back and neck, and loosen muscles. Cooling works best for ankle sprains.
- Ultrasound: An ultrasound sends high frequency sound waves over your body and stimulates deep body tissues. Vibrations produced by sound waves help to stimulate blood flow and facilitate the healing process. This procedure can also be used to improve metabolism and enhance the adhesiveness of bones after a fracture.
- Electrostimulation: In this procedure, an electric current is passed through the area which requires treatment. This helps in relieving pain, stimulating muscles and nerves, and expanding blood vessels.
These treatments may cause mild soreness or swelling. You can talk to your therapist in case it is prolonged.
