Focused Ultrasound Therapy
Focused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with soft tissue injuries. This novel technology focuses beams of ultrasound energy precisely and accurately on targets in the body without damaging surrounding normal tissue. Where the beams converge, the ultrasound produces small regions of damage (thermal lesions) within tendons, ligaments and other soft tissues in order to promote the growth of new connective tissue, which enables improved healing without the need for surgery. This technique was first used for plantar fasciitis and epicondylitis (tennis elbow). It has recently achieved the CE mark in Europe for widespread use on musculoskeletal injuries.
The primary options for treatment of subcutaneous injuries include medication and invasive surgery.
For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications and lower cost.
- Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
- Focused ultrasound can reach the desired target without damaging surrounding tissue.
- It can be repeated, if necessary.
Regulatory Approval and Reimbursement
Focused ultrasound treatment for soft tissue injury is not yet approved by regulatory bodies or covered by medical insurance companies in the US. Actisound has the CE Mark in Europe for soft tissue injuries.
