Focused Ultrasound Therapy
Focused ultrasound is a rapidly evolving, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with arthritis. This novel technology focuses beams of ultrasound energy precisely and accurately on targets 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.
There are multiple targets that can be treated. This section gives overall information, but please see specific entries for arthritis of the knee, hip, hand, and sacroiliac joint as well as the section on back pain. For many types of arthritis, the option of joint replacement is considered. Unfortunately, even with a quality primary joint replacement, the new joints do wear out, raising the need for a revision joint replacement (a second procedure on a previously replaced joint). The revision surgery is a much more difficult task than a primary one. The use of focused ultrasound in delaying the timing of the primary joint replacement, may eliminate the need for a revision surgery.
The primary options for treatment of arthritis include medication and invasive surgery.
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.
There are currently no active clinical trials for focused ultrasound to address arthritis.
Regulatory Approval and Reimbursement
The Insightec magnetic resonance-guided focused ultrasound system has been approved in Europe and Russia for the treatment of back pain secondary to facet joint arthritis.
