Focused Ultrasound Therapy

Focused ultrasound is a noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with arthritis of the sacroiliac region. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue.

How it Works
Where the beams converge, the ultrasound produces precise ablation (thermal destruction of tissue) enabling the nerves that carry painful signals from arthritis to be treated without surgery. 

The primary options for treatment of sacroiliac pain include medication and surgical procedures. 

For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications – such as surgical wound healing or infection – at a lower cost. It can reach the desired target without damaging surrounding tissue and is repeatable, if necessary.

Clinical Trials

At the present time, there are no clinical trials recruiting patients for treatment of sacroiliac arthritis.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for sacroiliac arthritis is not yet approved by regulatory bodies or covered by medical insurance companies.
