An injection of long-lasting steroid and local anesthetic into a specific region of the body, such as, a joint, bursa, around a tendon, or around a nerve. This procedure is typically performed to relieve pain and reduce inflammation. This procedure is performed by a Radiologist doctor using Ultrasound or CT guidance.
No preparation is required although it is important to contact us and let us know if you are taking any blood thinning medications or have any drug allergies prior to the appointment.
The procedure usually takes about twenty (20) minutes.
➢ Depending on which part of the body that requires injection you might be asked to change into a gown.
➢ You will be positioned on a table; the Radiographer or Sonographer may perform a limited scan.
➢ The area will be cleansed with an antiseptic.
➢ A short-acting local anaesthetic will be used to numb the skin around the injection site.
➢ Once the needle is accurately positioned, a mixture of long-acting local anaesthetic and corticosteroid will be injected.
➢ You might feel some pressure or discomfort during this process.
You may feel some discomfort and fullness in the joint after the study. This may be relieved with paracetamol (Panadol) and should settle down within twenty-four (24) hours. It is recommended you:
➢ Take it easy for the next 24 hours
➢ Resume your normal activities as limited by pain
➢ You may apply ice to the affected area
➢ You may continue with physiotherapy etc.
Any beneficial effect may eventually wear off. This is very variable, but the beneficial effect usually lasts several months. The area can be injected again if required.
