Hydro-dilatation for adhesive capsulitis (frozen shoulder)

Ultrasound-guided hydrodilatation is a modern technique used to address adhesive capsulitis, commonly known as frozen shoulder syndrome.

What is frozen shoulder syndrome?

Frozen shoulder syndrome is a condition characterized by pain and restricted shoulder movement. It is caused by adhesions and contraction of the joint capsule of the shoulder, significantly affecting the patient's daily activities.

Frozen shoulder syndrome is divided into stages:

  • Pain stage (freezing process): Characterized by increasing pain in the shoulder, especially during movement. The range of motion starts to decrease, making everyday activities challenging. This stage can last from a few weeks to several months.
  • Stiffness stage (frozen shoulder): In the second stage, pain may decrease, but the shoulder becomes increasingly stiff. The range of motion is significantly limited, making daily activities even more difficult. This stage can last from 4 to 12 months.
  • Recovery stage: In this stage, gradual improvement is observed as the range of motion begins to improve, and pain continues to decrease. Full recovery can take several months and, in some cases, up to two years.

What causes frozen shoulder syndrome?

Risk factors for frozen shoulder syndrome include:

  • Diabetes
  • Thyroid disorders
  • Previous shoulder surgery
  • Shoulder pathology, such as tendon tear and calcific tendonitis

What is hydrodilatation for treating frozen shoulder?

Frozen shoulder syndrome can be treated with a minimally invasive technique called hydrodilatation. Hydrodilatation involves injecting a mixture of saline solution and local anesthetic into the joint capsule to expand it and neutralize adhesions. If inflammation is present in the joint capsule, corticosteroid injection may also be administered for relief.

Hydrodilatation facilitates the restoration of the shoulder's range of motion, and a physical therapy program following the treatment can enhance the results.

What is the significance of ultrasound guidance in hydrodilatation for frozen shoulder?

Ultrasound guidance ensures the precise and safe placement of the needle within the joint capsule. This method is supervised by a specialized Radiologist, guaranteeing both the safe positioning of the needle and the avoidance of vital structures. Throughout the hydrodilatation procedure, the path of the needle within the capsule is continuously monitored, ensuring both safe placement and the avoidance of critical structures. The use of ultrasound guidance allows for optimal therapeutic results.
