Corticosteroid Injections


At times, diagnosis of a condition may involve aspiration of the joint and examination of the fluid under microscope. The characteristics of the fluid can help us differentiated between different types of arthritis. Most joints can also be injected with anesthetics and corticosteroids for rapid pain relief. Almost every joint can be injected to relieve pain. These are some of the joints that Dr. Firooz will aspirate and inject:

  • Hands
  • Feet
  • Shoulders
  • Elbows
  • Wrists
  • Knees
  • Ankles
  • Jaw (temporomandibular joint)
  • Lower back (facet joints)
  • Lower back (sacroiliac joints)


Injuries to tendons and bursae is very common and can result from sports or any repetitive movement of our daily lives. If conservative management does not resolve the pain, corticosteroid injection is very helpful for pain relief, and often, healing of the injury.

These are examples of such injuries:

  • Carpal tunnel syndrome (wrist)
  • Tarsal tunnel syndrome (ankle)
  • Lateral epicondylitis (tennis elbow)
  • Medial epicondylitis (golfer’s elbow)
  • DeQuervain’s tenosynovitis (thumb)
  • Subacromial bursa (shoulder)
  • Trochanteric bursa (hip)
  • Patellar bursa (knee)
  • Trigger finger (locked finger)

Hyaloronic Acid Injections

Hyaluronic acid is a viscous material that lubricates the joint and is thought to also stimulate cartilage growth. These injections are currently approved for the knee joint:

  • Synvisc
  • Synvisc-one
  • Hyalgan
  • Supartz
  • Euflexxa
  • Orthovisc

Musuloskeletal Ultrasound

Ultrasound is a safe and non-invasive method that allows us to look at a joint and its surrounding structures in real-time. It is more sensitive than xrays in detecting abnormalities, and less costly than MRI. We use musculoskeletal ultrasound to achieve these goals:

  • Guide the injection to ensure accurate placement into the joint
  • Detect inflammation in the joint
  • Diagnose tendonitis and tendon rupture


Infusion Therapy

Intravenous and injectable medications have made remission a possibility for a variety of rheumatologic diseases. The infusion time and frequency varies, depending on the medication.

  • Actemra
  • Benlysta
  • Boniva
  • Orencia
  • Prolia
  • Reclast
  • Remicade
  • Simponi Aria


Xray is a commonly used tool in rheumatology to help evaluate a joint. We offer Xray services on site, so you can easily have them done at the same time as your visit.

Xrays are done by trained technicians and personally reviewed by Dr. Firooz.

Clinical Studies

New medications are being developed for treatment of rheumatologic diseases. We frontier this progress by offering our patients participation in carefully selected studies. You benefit by getting a medication that is not yet on the market; getting a medication that is already on the market for free; or simply by contributing to medical research.

We currently have studies involving the following diseases:

  • Rheumatoid arthritis
  • Ankylosing spondylitis
  • Fibromyalgia

Dr. Firooz often sees patients who come to our West Hills office from nearby communities such as Woodland Hills, Calabasas, Simi Valley, Tarzana, Encino, Northridge, Chatsworth, Reseda, Agora Hills, Westlake Village, Thousand Oaks and Van Nuys.
