Bursa Injection (Interspinous / Ischial)
What is a Bursa Injection?
- Bursa are small pockets of fluid located around the joints where muscles and tendons glide over bones. Their function is to decrease the friction between the two surfaces as they move in different directions.
- Bursa can become inflamed (bursitis), leading to swelling and pain.
- Common causes of bursitis are repetitive movements, prolonged excessive pressure or injury.
- A bursa injection involves the injection of local anaesthetic and steroid into the bursa to reduce pain due to bursitis.
- Our doctors do injections into the interspinous bursa or ischial bursa:
- Interspinous bursitis (also known as Baastrup's syndrome or kissing spine) occurs between adjacent spinous processes (bony ends of the vertebrae) where they "kiss" and rub against each other.
- Ischial bursitis may be a cause of pain in the buttocks (sitting bone) or hamstrings, especially when running or sitting.
- The injection procedure is performed in the day surgery using an X-ray machine.
Prior to the Procedure
- All blood thinning products (except aspirin) must be stopped prior to your procedure. You will be advised by letter when to stop taking these medications at the time that your admission date is arranged.
- You are able to take your other regular medications with a sip of water on the morning of your procedure.
- If you are an insulin dependent diabetic you will always be at the beginning of the list. Please bring your insulin with you and it will be given to you following your procedure.
- Hamilton Day Surgery Centre staff will advise you of your fasting and admission times.
- You must not have anything to eat, drink, smoke or chew prior to your procedure.
- You will need to organise someone to drive you home after the procedure as you will not be able to drive for 24 hours after your procedure.
What Will Happen?
- You will be admitted to the day surgery by a nurse and you will be asked to change into a gown.
- The anaesthetist will speak with you and place a cannula (plastic needle) into a vein in your hand.
- In the procedure room, you will be assisted to position on the procedure table lying on your abdomen with a pillow under your hips and abdomen.
- The anaesthetist will give you some sedation into your vein.
- An X-ray machine will be used to determine where the doctor will place the needle for your procedure.
- Local anaesthetic and sometimes also corticosteroid will be injected into the bursa, once correct needle placement has been established with use of X-ray.
- The procedure will take approximately 10 minutes to complete.
- After the procedure, you will be placed on a trolley and taken to recovery, where you will remain for approximately 1 hour.
- After having something to eat and drink, you will be discharged with a carer.
- Gentle activity and rest is recommended in the first 24 hours following the procedure. You may then return to normal activity.
- The local anaesthetic will wear off 12-18 hours following your procedure.
- The steroid will take approximately 48 hours to start working.
- During this time there may be some increased discomfort or pain.
- A nurse from HPC will telephone you 24 to 48 hours following your procedure to check on your progress and organise a follow up appointment.
