Piriformis Muscle Block
This procedure involves the injection of local anaesthetic and steroid into the piriformis muscle, which may be causing the pain in your buttock and leg. This procedure may reduce inflammation, resulting in long-term pain relief.
You will be asked to lie flat on your front and a pillow will be placed under your pelvis.
You will receive deep intravenous sedation during the procedure and I will also numb the skin and deeper tissues with a local anaesthetic prior to inserting the needle into the epidural space at the bottom of your spine.
The procedure is done under X-ray control in order to increase its accuracy and routinely inject a radio-opaque dye.
It is very important to tell me if you are allergic to Iodine or to seafood, as in these cases, it would be safer not to inject the dye.
The medications will be injected next, which may create a brief pressure-like sensation.
Due to the effects of certain medications, your driving reflexes may be impaired, consequently you will need someone to drive you home after the procedure, so please make the necessary arrangements in advance.
- If you are on specific blood thinning medications (e.g. Warfarin or Plavix), Aspirin or Anti-inflammatory drugs (e.g. Ibuprofen, Diclofenac) you should ensure that you let my secretary know as soon as possible on 020 8504 4816
