Targeted muscle reinnervation (TMR) is a new surgical procedure that reassigns nerves that once controlled the arm and the hand. By reassigning existing nerves, doctors can make it possible for people who have had upper-arm amputations to control their prosethic devices by merely thinking about the action they want to perform. Once experimental, this innovative procedure is now available at The Johns Hopkins Hospital.
People who undergo the targeted reinnvervation surgery will be fitted with and trained to use a myoelectric prosthetic arm.
Who might benefit from Targeted Muscle Reinnervation surgery?
Those interested in the procedure to better control their prosthetic arm must undergo a medical review to determine their eligibility. In general, patients must meet the following criteria:
- Amputation above the elbow or at the shoulder within the last 10 years
- Stable soft tissues
- Willing to participate in rehabilitation
Those who were born without part or all of their arm and those who have nerve damage, degeneration or paralysis are not candidates for this procedure.
