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 painful neuromas which can occur after an amputation. This is a very specific type of neuropathic pain. This novel technology focuses beams of ultrasonic energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue.
How it Works
Where the beams converge, focused ultrasound produces precise ablation (thermal destruction of tissue) enabling the neuromas to be treated without surgery.
The primary options for treatment of painful amputation neuromas 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.
In Israel, there is a clinical trial using focused ultrasound to ablate painful neuromas (visualized on MRI) that are causing amputee stump pain, and the impact on the patient’s level of pain is assessed.

Regulatory Approval and Reimbursement
Focused ultrasound treatment for painful amputation neuromas is not approved by regulatory bodies or covered by medical insurance companies.
