New titanium implant could let amputees ditch the socket

NCT ID NCT06636136

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing a titanium implant called OPRA that connects a prosthetic leg directly to the shinbone, bypassing the need for a traditional socket. Researchers will follow 30 adults with below-knee amputations for up to 5 years after surgery to see if the implant improves function, reduces pain, and boosts quality of life. The goal is to offer a better option for people who have trouble using a socket prosthesis.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
OPRA implant system (titanium implant surgically placed into the shinbone to attach a prosthetic leg directly to the bone)
What this could lead to
If successful, this could offer a more comfortable and functional alternative to traditional socket prostheses for people with below-knee amputations, potentially improving mobility and reducing skin problems.
What could go wrong
This is an early-stage study with only 30 participants, so results may not apply to everyone. Surgery carries risks like infection, implant failure, and the need for additional procedures.
