What are Ultrasound-guided Injections?
An ultrasound guided injection is a minimally invasive procedure used to treat various painful musculoskeletal conditions such as tendonitis, bursitis and neuritis. Guided injections can be used to perform cyst aspiration as well as to guide the placement of needles for both diagnostic and therapeutic purposes
Injection of pain medication with a local anaesthetic directly to the site of injury to help relieve pain. The advanced imaging of the ultrasound provides high-resolution images that enable your physician to precisely locate the injections deep into the target tissue without harming surrounding tissues.
There is a significant body of research indicating that ultrasound-guided intra-articular joint injections are not only safer but also give better and longer-lasting pain relief. This means that the benefits are experienced sooner and the beneficial effects such as pain relief and improvement in function last longer.

Genuine Patient Reviews

Immediately after the cortisone injection I felt better next day I took the flight to sharm a year on I feel great never had any issue with the leg
Thanks to Robert Mast

Well the difference was night and day there was a almost an instantaneous change, I had been told that after the initial pain killer wore off that it might take up to 7 Days for it to start working but I found it more bearable from the next day and by the time I flew to Florida 5 days later I was walking but with stiffness and some night time pain on resting, by 10 days I was walking and swimming with some pain but nothing anywhere like it was, now a month after the initial injection there is barely any pain unless I get it cold and then I can still walk and the pain is bearable.
It was the best money I have ever spent and Rob was professional, extremely knowledgeable and made me feel at ease from the first moment we meet.
Procedure went very well
Took no time at all
I will go back to Rob in future as necessary
Thank you
Met with Rob again after two years at his Hertford clinic for a guided Steroid injection into my shoulder that was painful after a fall. The procedure went very well and my shoulder is back to normal.
Just like the last time he administered an ultrasound guided injection. I limped into the clinic in terrible pain and once he administered the injection all my pain disappeared. No limping and did not need to hold onto my son’s arm.
Rob takes time to listen and then explains the procedure, so helpful.
Thank you Rob.
Went through the whole procedure in clinic with me
Had physio with Nicola after, who i cant not fault
I get odd pain now again in my shoulder when its cold and damp
Thanks Rob, for you kind help and i would use u again and practice
thanks

The results of the treatment have been exceptional. I can move freely and in complete comfort and my wife says there is no longer any sign of a limp or uneven gait. The moments of sharp pain I would typically experience two ot three times a day have been completely absent and I no longer find myself tensing in anticipation before standing from sitting, approaching stairs, or turning over in bed.
Highly recommend Rob as a specialist in this area.
Rob was able to see my wife at a couple of days notice, and following a physical examination and an Ultrasound scan, identified the problem as subacromial bursitis, which would benefit from an Ultrasound guided cortisone injection.
The "3 stage" process all took place within the same appointment ( a major plus) and was completed in under an hour and at a very reasonable cost.
Within a week, my wife experienced a major improvement in her condition, and is now back to normal after less than 4 weeks.
A full clinical report, together with the Ultrasound photos were received a week or so later, as well as a copy being forwarded to our GP with her agreement.
Based on our experience, we would highly recommend Rob to anyone who feels his expertise would be beneficial.
We all know when we are injured we want things sorted right away & I was extremely happy that he squeezed me in for an appointment the following Thursday.
At the appointment he explained everything as we went along & hopefully now with the steroid injection I can move forward.

Robert Mast at Sonoscope kindly saw my mother with a few days of making the appointment . Excellent service and superb bedside manners. Made my mother feel at easy and the steroid injection administered under Ultrasound worked brilliantly. Literally the next day my mother started to feel the benefits of the treatment. I would highly recommend Robert and his clinic to anyone needing help with pain relief.
Very honest and very well priced .
I certainly will reccomend him
Rob is great, explains everything clearly. My nan is very happy. She only got one knee done. Now she’s saying She wants to go back to see Rob to do her other knee. Friendly, informative and efficient service. We’d highly recommend. Great service.
He kept me informed and explained the procedure step by step, happy to answer my never-ending questions.
This helped immensely as it was the 1st time having this treatment and therefore was pretty nervous. Robs friendliness and reassurance kept me calm and would highly recommend him.
Condition and outcome explained in a simple but comprehensive way. Empathetic practitioner.
Would highly recommend.
The ultrasound guided injection was carried out in a professional reassuring manner. Thank you
Rob is friendly and professional. He explains everything to you, in terminology that you understand which is super helpful.

Brilliant service and a very kind considerate practice.
We would have no hesitation in recommending Rob, a true professional and my mothers shoulder is at long last free from pain.
I attended for injection into the glenohumeral joint for frozen shoulder (6 months since onset) but because I was experiencing extreme pain at a different part of my shoulder (2 days since onset) he took the trouble to understand this new event and offer the cortisone injection in a different location. This injection alleviated the pain and I was able to return two weeks later for the planned frozen shoulder injection.
I was a bit nervous before going in, but the lovely and friendly receptionist soon cheered me up.
Rob was friendly , calm and very professional.
He explained everything and showed me the procedure while showing me the area going to be treated on the ultrasound screen step by step.
I highly recommend Rob and would certainly go back if I should require further treatment
Rob is very professional and takes the time to explain what he is looking at on the ultrasound and what he is doing to do and why.
I would certainly recommend.




I was seen at the booked time by very pleasant professionals.
The injection was swiftly and professionally administered.
12 hours later the pain is very very much reduced and I am hoping for no pain after 24 hours





I then had an injection at Sonoscope. The ultrasound guided injection was done by Rob who clearly knew his stuff and explained the injection in detail. He made me feel at ease. The injection was almost painless and exactly into the bursa. Within a week I was pain free! This allowed me to progress further with exercises. He would highly recommend his services !

What happens during the ultrasound-guided joint injections?
During your visit to our pain clinic, you will receive an expert clinical assessment followed by a diagnostic ultrasound scan to determine whether injection therapy is the correct treatment for you. This will help to evaluate the source of your pain symptoms and to identify the correct area to inject the ultrasound-guided joint injections.
What if the ultrasound guided injection is not for me?
If ultrasound guided injection therapy is not thought to be appropriate for you will be given a full explanation of the assessment findings including advice regarding appropriate management. In that case, you will only be charged a fee for the ultrasound scan, but not for the injection.

Important
Areas in red are often areas of referred pain from the spine and not joint. Steroid injections in these areas may not target the source of the pain (the spine).
If unsure about the source of your pain, please discuss it further with us.
List of ultrasound-guided procedures
The list of injectable structures with cortisone steroid injections displayed in the adjacent box is not exhaustive and does not include all structures that we inject.
Please contact us directly if the condition that you are looking for is not listed, as we might still be able to help you.

Let's find the source of the pain
Please note
Injections are not given to any person of 16 years of age or younger. Unfortunately we cannot provide injections for professional football players for reasons of insurance.
Injection information leaflet
Please make sure that you have read the relevant patient information leaflets on the relevant type of injection (steroid or Hyaluronic acid) to ensure that injection therapy is appropriate for you. Once you have been booked for an appointent you will be asked to complete an online form with questions about the condition you are sufereing from as well as questions about your general medical health this form helps us to plan the procedure and make sure it is an appropriate treatment for you.
Informed consent
On the day of the injection you will be asked to sign an informed consent form. Please make sure that you have read all the information on the injection you will be having including risks and side effects. Without being aware of the risks and side effects you will not be able to provide informed consent so please take some time to read this before your injection.
Advantages of ultrasound-guided Injections
Musculoskeletal ultrasound has a great many advantages over other types of diagnostic imaging. The many benefits of ultrasound-guided injections include:
Being safe, noninvasive, and painless.
Being widely available and uncomplicated to use
Being far less expensive than MRI and CT scans
Having the ability to show clear pictures of soft tissue (unlike X-rays)
Showing images in real-time to guide injections and other procedures
Not contraindicated for those with pacemakers and other implants
Providing very clear images
Ultrasound-guided injections, therefore, present a major step forward in the treatment of musculoskeletal injuries.
Are Ultrasound Guided Procedures Safe?
High-resolution ultrasound guidance during injection procedures dramatically increases their safety, since the injections are accurately targeted to the treatment site.
There is a plethora of research studies concluding that ultrasound-guided needle procedures significantly enhance patient safety and quality of care. At the same time, ultrasound-guided procedures eliminate complications that can arise from “blind” needling therapies and injections.
If you’re planning to drive after your injection, it’s best to make sure you understand how the treatment might affect you. Some patients may experience mild dizziness or temporary weakness, depending on where the injection is given. You can read our full guidance on when it’s safe to drive after a steroid injection here.
Sonoscope also offers hydrodistention injections as well as hyaluronic injections
Injections are not given to any person of 16 years of age or younger. Unfortunately we cannot provide injections for professional football players for reasons of insurance.
