Therapeutic Joint Injections

Therapeutic joint injections are a minimally invasive treatment option used to relieve pain caused by inflammatory joint conditions such as osteoarthritis, rheumatoid arthritis, tendonitis, bursitis and gout. Corticosteroids, used to reduce inflammation and minimize pain as a result coupled with numbing medicine (lidocaine and/or marcaine), are injected into the affected joint. This medication only affects the targeted area and does not usually cause side effects in most patients. Joint injections are administered under local anesthesia and only cause mild, brief discomfort for patients.

Patient Experience

Our technologists are specially trained and certified by the American Registry of Radiological Technologists. During the study, you will lie on your back on a motorized X-ray table. After local anesthesia, a needle is maneuvered into the area of interest under fluoroscopic guidance. Correct needle placement is confirmed by using a combination of imaging and injection of a small amount of iodinated contrast. A combination of a short-acting anesthetic, such Marcaine/Lidocaine, and an intermediate to long acting corticosteroid, such as Kenalog, are then injected. The anesthetic can provide immediate pain relief lasting 4-6 hours while the corticosteroid takes effect approximately 1-2 days after the injection, reaching maximum effectiveness within 5-7 days. The duration of the pain relief varies depending on the severity and reversibility of the patient’s condition. If therapeutic effect is achieved, several injections per year can be performed with few long term consequences.

Our radiologists are well trained in performing diagnostic and therapeutic injections of multiple joints including:

  • Shoulder
  • Elbow
  • Wrist
  • Hip
  • Knee
  • Ankle
  • Foot

After The Exam

Once the procedure is completed, you will be discharged home with instructions that include minor to normal activity for the remainder of the day. You are then to follow up with your referring physician as he/she will need to know how you responded to the medication/procedure.
