Mode of Action of Hydrodilatation
Hydrodilatation involves injecting a sterile solution—a mixture of saline, corticosteroid, and local anaesthetic—directly into the shoulder joint. This fluid stretches and expands the thickened, contracted joint capsule typical in frozen shoulder. By distending the capsule, the procedure reduces inflammation and gradually restores joint mobility.
Hydrodilatation
Hydrodilatation, also known as distension arthrography, is a non-surgical treatment designed to relieve pain and improve movement in patients with frozen shoulder (adhesive capsulitis). This specialised procedure uses advanced ultrasound guidance to ensure precise delivery of medication and a comfortable experience.
Procedure of Hydrodilatation for Frozen Shoulder
Local Anaesthetic: The shoulder area is numbed to minimise discomfort.
Ultrasound Guidance: Real-time ultrasound guides a fine needle precisely into the shoulder joint.
Injection of Solution: The sterile solution is slowly injected into the joint capsule.
Joint Capsule Stretching: The fluid expands the tight capsule to improve range of motion.
Quick Procedure: Usually completed within 15 to 30 minutes.
Post-Procedure: Patients can typically return home shortly after treatment.
Conditions Treated with Hydrodilatation
Frozen Shoulder (Adhesive Capsulitis)
This condition causes pain, stiffness, and restricted movement due to inflammation and thickening of the shoulder joint capsule, severely limiting daily activities.
Benefits of Hydrodilatation
Minimally invasive, no surgery required
Effective pain relief by reducing joint inflammation
Improves shoulder mobility by expanding the capsule
Quick recovery with most patients resuming normal activities soon after
Ultrasound guidance ensures accurate needle placement
Short procedure time, generally under 30 minutes
