MUSCULOSKELETAL ASPIRATION AND INJECTIONS

MUSCULOSKELETAL ASPIRATION AND INJECTION

For injection, ultrasound is used to accurately guide needle tip placement into the region of interest, be it a joint, bursa, tendon sheath or other structure, prior to the injection of therapeutic material (local anaesthetic, steroid, hyaluronic acid (Durolane/Synvisc) or platelet rich plasma (PRP)). Our philosophy is to take care to use the smallest needle available to achieve our objective and to try to make the procedure as painless as possible.

For aspiration, ultrasound is used to guide needle tip placement into a fluid collection, be it a joint effusion, fluid distended bursa, ganglion or other, prior to the aspiration (withdrawal) of fluid (occasionally calcium) from the collection. This fluid may be sent to pathology for testing.

An injection is often done in association with an aspiration. If there is fluid in a joint we routinely aspirate all of the fluid before injecting the cortisone. This helps to relieve symptoms and renders the cortisone more effective.
