Ultrasound-guided infiltration

Ultrasound-guided infiltration involves injecting an anti-inflammatory drug into joints, bursae or tendons to relieve pain and reduce inflammation. The radiologist uses an ultrasound machine as a guide and to see the infiltration site clearly.

Ultrasound-guided infiltration can effectively treat many joint problems using the following techniques:

  • Cortisone infiltration
  • Viscosupplement infiltration (Synvisc)
  • Calcium washing
  • Nerve block


Fluoroscopy-guided infiltration

Fluoroscopy-guided infiltration allows the health care professional to see the bones and joints and verify their manoeuvres during the procedure. The following infiltrations are performed using fluoroscopy:

  • Intra-articular
  • Facet blocks
  • Foraminal (or selective epidural) blocks
