Shoulder Anterior Capsular Block (SHAC Block)
The Shoulder Anterior Capsular Block (SHAC Block) is a minimally invasive procedure designed to relieve pain and restore mobility in patients with frozen shoulder. During this procedure, a local anaesthetic and steroid are injected into the anterior capsule of the shoulder joint, specifically targeting the inflamed and restricted areas. This procedure is performed under ultrasound guidance at RAD Clinics to ensure precise targeting of the capsule, reducing pain and inflammation.

Benefits of Shoulder Anterior Capsular Block at RAD Clinics
- Effective Pain Relief: The SHAC Block offers immediate relief by numbing the inflamed capsule, reducing discomfort and enabling patients to engage in physical therapy and rehabilitation with less pain.
- Enhanced Mobility: By reducing inflammation, the SHAC Block allows patients to regain shoulder movement, particularly during the early stages of treatment.
- Minimally Invasive: The procedure is non-surgical and performed with a fine needle under ultrasound guidance, minimising risks and complications.
- Accurate Targeting with Ultrasound Guidance: At RAD Clinics, our expert clinicians use real-time ultrasound imaging to guide the injection, ensuring precise placement into the anterior capsule, which improves the effectiveness of the block.
- Complement to Physiotherapy: The SHAC Block is often used in combination with physical therapy, allowing patients to perform exercises and stretches more effectively as pain and stiffness subside.
How SHAC Block Helps with Frozen Shoulder
The SHAC Block works by addressing both the inflammatory and painful components of adhesive capsulitis. The local anaesthetic temporarily numbs the pain, while the corticosteroid component reduces inflammation within the shoulder capsule, facilitating a quicker recovery.
By reducing inflammation, the SHAC Block enables patients to move their shoulder with less pain, which is essential for breaking the cycle of stiffness that defines frozen shoulder. The procedure also aids in the reduction of scar tissue formation and adhesions, further restoring range of motion.

What to Expect During the SHAC Block Procedure
At RAD Clinics, the SHAC Block is performed in an outpatient setting under ultrasound guidance. Here’s what you can expect during the procedure:
Patient Positioning: You will be positioned comfortably, often seated or lying on your back, to allow optimal access to the shoulder joint.
Ultrasound Visualisation: Our clinician will use an ultrasound machine to visualise the anterior capsule of the shoulder, ensuring that the injection is placed precisely.
Anaesthetic and Steroid Injection: A combination of local anaesthetic and corticosteroid is injected into the shoulder capsule to reduce inflammation and provide pain relief.
Post-Procedure Care: After the procedure, patients typically experience immediate relief from pain, and shoulder exercises are often recommended to maintain mobility.
