Ultrasound-Guided Hydrodilatation
Ultrasound-guided hydrodilatation is a minimally invasive procedure used to treat frozen shoulder, a condition where the shoulder becomes painful and stiff due to tightening of the joint capsule. This treatment aims to reduce pain, improve movement, and support faster recovery when combined with guided exercises and rehabilitation.
At The London Ultrasound Clinic, we carefully select this procedure for patients who have persistent shoulder stiffness or pain, particularly when other treatments such as physiotherapy or steroid injections have not provided lasting relief.
What the appointment includes
- A detailed discussion about your symptoms, movement difficulties, and goals.
- Hands-on shoulder examination to assess range of motion and identify areas of restriction.
- Ultrasound assessment of the shoulder joint to visualise the joint capsule and surrounding structures.
- Ultrasound-guided hydrodilatation injection using sterile saline, local anaesthetic, and steroid to gently stretch the joint capsule.
- Clear explanation of the findings and step-by-step guidance throughout the procedure.
- A written report including aftercare advice and exercise recommendations to support recovery.
What to expect
The injection is performed under real-time ultrasound guidance to ensure accurate placement of the fluid within the joint capsule. The procedure gently stretches the capsule, helping to break down adhesions and improve mobility. Most patients tolerate the procedure well, although some temporary discomfort during the injection is normal.
After the procedure, your clinician will provide clear instructions on safe movement and exercises to maintain and improve shoulder mobility. Most patients can return to normal daily activities shortly afterwards, with ongoing improvement over the following weeks.
How it helps
Hydrodilatation works by physically expanding the tight joint capsule, breaking down adhesions and reducing pain and stiffness. The saline gently stretches the capsule, the steroid helps settle inflammation, and the local anaesthetic provides immediate pain relief. The procedure is most effective when combined with a structured rehabilitation programme, including guided exercises to restore range of motion and strength. Many patients notice gradual improvement in pain and shoulder function within days to weeks, with continued gains over several months.
