Ultrasound guided shoulder injection London — performed by a specialist musculoskeletal radiologist — is one of the most effective, fastest-acting treatments available for a range of painful shoulder conditions. This guide explains the three main shoulder injection sites, what each one treats, what to expect on the day, and why ultrasound guidance is essential for accuracy and safety.

Why Ultrasound Guidance Matters
Historically, many shoulder injections were performed “blind” (using anatomical landmarks alone). Research has consistently shown that blind injections miss the intended target in up to 30-40% of cases — particularly in the complex, tight spaces of the shoulder joint.
At London Sports and Rheumatology Imaging, every shoulder injection is performed under real-time ultrasound guidance. This means Dr Prashant Sankaye watches the needle entering the exact target structure on a live ultrasound screen throughout the procedure. This ensures:
- 100% accuracy in delivering the medication to the source of the pain
- Avoidance of injecting directly into a tendon (which can weaken it)
- Avoidance of nerves and blood vessels
- Significantly less pain during the procedure
- Better, faster clinical outcomes
The Three Main Shoulder Injection Sites
There is no single “shoulder injection.” Depending on your diagnosis, the injection will be targeted to one of three specific areas:
1. Subacromial Bursa Injection
The subacromial bursa is a fluid-filled sac that sits above the rotator cuff tendons. When it becomes inflamed, it causes pain when lifting the arm (impingement).
- Treats: Subacromial bursitis, rotator cuff tendinopathy, impingement syndrome.
- Goal: Reduce inflammation in the bursa to allow the rotator cuff tendons to glide smoothly and without pain.
2. AC Joint (Acromioclavicular Joint) Injection
The AC joint is the small joint at the very top of the shoulder where the collarbone meets the shoulder blade.
- Treats: AC joint osteoarthritis, AC joint injury (often from weightlifting or falls), osteolysis of the distal clavicle.
- Goal: Deliver targeted anti-inflammatory medication directly into this very narrow joint space.
3. Glenohumeral Joint Injection
The glenohumeral joint is the main “ball and socket” joint of the shoulder.
- Treats: Frozen shoulder (adhesive capsulitis), glenohumeral osteoarthritis.
- Goal: Reduce profound joint inflammation and, in the case of frozen shoulder, distend the contracted capsule (a procedure known as hydrodistension).
What Injection Is Right for You?
Once the target site is identified, we select the appropriate medication:
- Corticosteroid: The gold standard for rapid reduction of acute inflammation. Provides fast pain relief lasting weeks to months.
- Hyaluronic Acid: A thick, lubricating gel used primarily for osteoarthritis. It acts as a shock absorber and provides longer-lasting relief (6-12 months) without the side effects of steroids.
- PRP (Platelet-Rich Plasma): A regenerative injection using your own concentrated blood platelets to stimulate tissue healing in torn tendons or degenerated joints.
What to Expect on the Day
The procedure is fast and performed in our clinic room. You will be seated comfortably. Dr Sankaye will scan your shoulder with the ultrasound probe to confirm the diagnosis and locate the target. The skin is cleaned, and local anaesthetic is often mixed with the injection to numb the area immediately. The injection itself takes only a few minutes.
