Shoulder Hydrodilatation
Hydrodilatation is an effective treatment for frozen shoulder (adhesive capsulitis). Under imaging guidance, the joint capsule is distended with fluid, steroid, and local anaesthetic. This stretches the contracted capsule and can significantly improve range of motion and reduce discomfort.
Duration:20-30 minutes
Results:Improvement typically seen over 1-4 weeks with physiotherapy
