Hydrodilatation Procedure for Frozen Shoulder
Effective Pain Relief & Improved Mobility
Frozen shoulder, also known as adhesive capsulitis, is a condition that causes stiffness, pain, and restricted mobility of the shoulder joint. If you have been diagnosed with frozen shoulder and have had a steroid injection, but the shoulder range of motion has not improved, the Hydrodilatation (hydrodistension) procedure may be an effective option for you.
What is Hydrodilatation?
Hydrodilatation is a minimally invasive procedure that improves shoulder mobility by injecting a sterile fluid mixture into the shoulder joint capsule. The goal is to stretch the capsule, break down adhesions, and restore movement.
How Does It Work?
A combination of saline, corticosteroid, and local anaesthetic is injected into the joint. The fluid expands the capsule, reducing stiffness and improving range of motion. The procedure is performed under ultrasound guidance for precise placement.
Benefits of Hydrodilatation for Frozen Shoulder
Rapid pain relief within days (Chen et al., 2024)
Improves shoulder mobility by stretching the joint capsule
Minimally invasive alternative to surgery
Enhances physiotherapy outcomes by reducing stiffness and discomfort
Ultrasound guidance ensures accuracy and safety
What to Expect During the Procedure
The shoulder is sterilised, and a local anaesthetic may be applied.
Ultrasound imaging ensures precise placement of the injection.
A sterile fluid mixture (saline, corticosteroid, and anaesthetic) is injected into the joint capsule.
The fluid expands the capsule, improving mobility and reducing pain.
The procedure is quick, taking about 15-30 minutes.
Who Can Benefit from This Treatment?
Hydrodilatation is recommended for individuals who:
Have persistent shoulder stiffness and pain due to frozen shoulder
Experience limited range of motion affecting daily activities
Have not responded to physiotherapy and other conservative treatments
Want to avoid or delay surgical intervention
Post-Procedure Care & Recovery
Resume gentle shoulder exercises after 24-48 hours
Apply ice packs if mild swelling occurs
Avoid heavy lifting or strenuous activities for a few days
Follow up with physiotherapy for long-term mobility improvement
How Long Does Pain Relief Last?
Most patients experience significant improvement within a few weeks, with effects lasting several months to years, depending on the severity of the condition and adherence to physiotherapy.
Potential Side Effects
Hydrodilatation is safe with minimal risks. Possible side effects include:
Temporary soreness at the injection site (Chen et al., 2024)
Mild swelling or discomfort (Puko et al., 2023)
Rarely, infection or allergic reaction (Poku et al., 2023)
