UpgradeA medial branch block is an injection over the tiny nerve to the facet joint. The injection provides information about whether pain is coming from your facet joints.
Usually, several injections are undertaken during the same procedure. It is used for localised spinal pain where simpler measures have not helped. It can help your pain by reducing some of the pain signals from the joint. Though pain relief is usually short-lived, some people can get significant and more long lasting pain relief from these injections.
Facet joints are small joints that link the bones of the spine together. The facet joints allow movement and stabilise the spine. Wear and tear, inflammation and injury to the facet joints may cause pain in some people. Several injections to different facet joints may be needed depending on the site of pain. The injection contains local anaesthetic often with a small amount of steroid. The injection is usually undertaken alongside other treatments such as physiotherapy.
Other treatment options will be discussed with you before deciding to go ahead with the injections and your consent is needed. The decision on whether or not to go ahead with the injection(s) is a shared decision between you and your doctor. Your doctor will be able to provide you with up-to-date information about the likelihood of this being a successful treatment for you and how this treatment fits into the best pathway of care. If you are undecided about whether or not to have injections then further advice and information to make this informed decision can be provided. Please speak to your doctor for more information.
If your health has changed, it is important to let your doctor know;
Steroids have been used for a long time with only small risks. Around a quarter of medicines used in pain medicine are unlicensed - this means that the medicine has not been approved by a regulatory body for the purpose for which they are to be used. Therefore, these steroids cannot be marketed by the pharmaceutical industry. Medicines will only be licensed if there is a need for a pharmaceutical company to do this as the process of licensing is very expensive. Your doctor can discuss this with you further.
Before the injection, your doctor will discuss the procedure with you. Your doctor will either obtain your consent before the injection or confirm this consent if it was previously given. The treatment will take place in a dedicated area with trained personnel. An X-ray machine (or other forms of image guidance) will be used to enable accurate injection. Not all doctors undertake these injections in exactly the same way but the following usually happens;
After the injections you will be taken to a recovery/waiting area, where you will be observed. Your blood pressure and pulse may be checked. You will be given assistance to help to ensure that you can stand safely after the procedure.
You will usually be able to return home within 15-30 minutes after the injection, depending on how long your doctor or nurse want you to stay for recovery. Please ensure that you have made arrangements for someone to collect you after the procedure. Failure to do so will likely result in your procedure being cancelled. It is unsafe for you to drive home immediately after the procedure. If you do so your motor insurance will be invalid.
If in doubt, please discuss these issues with your doctor for further advice.
This will vary between individuals and may depend on the nature of your work. It is difficult to give general advice and so you should discuss this with your doctor.
As with any procedure, side-effects may occur. However, these are usually minor and there is little risk of serious harm.
Side-effects may include;
You may experience some soreness or aching at the injection site. Please keep the area of the injections dry for 24 hours following the procedure. Do not worry if your pain feels worse for a few days as this sometimes happens. Take your regular pain killers and medications as normal and this should settle down. Try to keep on the move about the house whilst avoiding anything too strenuous.
As your pain decreases, you should try to gently increase your exercise. Simple activities like a daily walk, using an exercise bike or swimming on your back will help to improve your muscle tone and strengthen your back. It is best to increase your activities slowly. Try not to overdo things on a good day so that you end up paying for it with more pain the following day.
