Focused Ultrasound Therapy
Focused ultrasound is an early-stage, non-invasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with tendon contractures. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the brain without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound can make small lesions in the tendons, either by thermal ablation or by mechanical methods. When these lesions heal, there is evidence that there is improvement in the tendon function. While significant preclinical work on this is being accomplished, there is still much to be done before this technology will be widely available.
The primary options for treatment of tendon contractures include medication and 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.
At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of tendon contractures.
Regulatory Approval and Reimbursement
Focused ultrasound treatment for tendon contractures is not yet approved by regulatory bodies or covered by medical insurance companies.
