Bursas are small sacs of fluid that reduce friction and help in the smooth movement between bones and muscles or tendons (band of tissue connecting muscle to bone) around a joint. Injury or overuse of joints can cause inflammation of these bursas. Trochanteric bursitis is the inflammation of the bursa that lies on the side of your hip bone (femur), causing pain, stiffness or pressure every time you move your hip. The pain may radiate down your thigh and also result in sleeping problems.
Pain can be relieved with a trochanter bursitis injection, which is a local anesthetic and a corticosteroid drug (anti-inflammatory) injected into the bursa of the trochanter (part of the thigh bone that connects to the hip bone) with the help of an imaging technique like X-ray.
Indications and Contraindications
The injection for trochanter bursitis is indicated to diagnose bursitis from other conditions, and also to reduce pain and inflammation of the bursa, but is contraindicated during pregnancy or failed response to previous 2-3 injections. Other contraindications include:
- Infection of the bursa
- High blood pressure
- Using anti-coagulant (blood thinner) therapy
- Fever or flu
- Broken skin over the site of injection
Your physician will physically examine your hip and back and evaluate your medical history. Pressure will be applied over the trochanteric area, if u experience tenderness and pain, trochanter bursitis is confirmed.
Trochanter bursitis injection is suggested if other conservative therapies, such as rest, oral analgesic medications and ice packs, fail to relieve pain and inflammation of the bursa. Steps in conducting the procedure include:
- You will lie down on the non-painful side of your body on a narrow table.
- Your doctor will clean the skin over the hip with an antibacterial solution and numb the area.
- Then, a needle with a mixture of local anesthetic agent and a corticosteroid drug will be injected into the affected area. X-ray images will be used to guide the needle into the correct spot of the painful area.
- The needle is then removed, and your skin will be cleansed to remove the antibacterial solution.
- A Band-Aid will be applied at the site of injection, and the procedure is completed in about 10 to 15 minutes.
Following the procedure, you may experience immediate pain relief due to the local anesthetic, but the steroid will show its effect around two or three days after the injection. Avoid driving for the remaining day. Ice can be applied for 20 minutes to relieve soreness or discomfort at the injection site. You can resume your normal activities on the day after the procedure. Normal diet and medications can be continued after the procedure. The length of pain relief may vary between individuals.
Risks and Complications
As with any procedure, trochanter bursitis injection involves certain potential risks and complications. These may include:
- Pain, bleeding and infection at the injection site
- Injury to the nerves or blood vessels
- Allergic reactions
- Short-term blood sugar increase in diabetics
- Fluid retention
- Tendon rupture
- Fat necrosis (death of fatty tissue)
Trochanter bursitis injection provides temporary pain relief: its effect lasting anywhere between a week to 6 months. You can be given repeated injections of up to three per year for treating the condition.
