Hydrodilatation for Adhesive Capsulitis (Frozen Shoulder)

Hydrodilatation for Adhesive Capsulitis (Frozen Shoulder)

The shoulder joint is encapsulated by a layer of connective tissue known as the joint capsule, which helps hold the bones in place and provides stability. In adhesive capsulitis (commonly called frozen shoulder), this capsule becomes thickened and tight, restricting the normal range of motion. The condition usually progresses through three stages: the freezing phase, the frozen phase, and the thawing phase. If the condition persists into the frozen phase, treatments like cortisone injections or suprascapular nerve blocks may become less effective. In such cases, hydrodilatation can offer significant relief.

What is Hydrodilatation?

Hydrodilatation is a minimally invasive procedure where a sterile fluid mixture is injected into the shoulder joint to gently stretch and expand the tight, contracted capsule. Think of it like blowing up a water balloon—the fluid distends the capsule, creating space and breaking up adhesions that restrict movement. The procedure not only helps to stretch the capsule but also includes a cortisone injection to reduce inflammation and minimize post-procedure flare-ups.

How the Process Works

Hydrodilatation is typically performed under ultrasound guidance to ensure precise placement of the injection. A mixture of saline, anesthetic, and corticosteroid is injected into the joint, gently stretching the capsule. This is often combined with manual manipulation of the shoulder to help break up adhesions and further improve mobility.
