Painful Amputation Neuromas

Focused Ultrasound Therapy

Clinical Trials SquareFocused 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. Where the beams converge, the 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 non-invasive alternative to surgery with less risk of complications and lower cost.

Advantages:

  • Focused ultrasound is non-invasive, so it does not carry added concerns like surgical wound healing or infection.
  • Precise targeting minimizes damage to non-targeted tissue.
  • Focused ultrasound treatment can be repeated, if necessary.

Clinical Trials

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.
