Osseointegration for finger and thumb amputations
Features
- Direct attachment to the bone for greater mobility
- Reduced pressure and risk of pain due to a socket
- Prosthesis attachment without the need for additional tools
Hand digit osseointegration
The OPRA® Implant System is a bone-anchored prosthesis attachment that creates a stable bond to the end of the amputated digit. It has the ability to restore up to 94% of function when used in the thumb.
The BioHelix™ surface technology allows the components of the OPRA® Implant System integrate with patient anatomy for stronger osseointegration and more rapid healing . Additionally, because the patient no longer needs a socket prosthesis, it is effective at eliminating pressure, pain, and lasting sores after implantation that a socket could otherwise cause. The components of the attachment are scaled to fit the smaller size of the thumb or finger stump.
System contents:
The OPRA® Implant System follows a modular design with three main parts to achieve fixation and attachment. Each performs a vital function for osseointegration between patient anatomy and the prosthesis.
- Fixture – the anchoring element that screws into the bone from the site of the amputation.
- Abutment – the connecting piece that penetrates the skin.
- Abutment Screw – the screw that attaches the Abutment to the Fixture.

Integrum has been performing research and development on orthopaedic solutions since the 1990s. The OPRA® Implant System offers an alternative to traditional socket prostheses, serving as a way to anchor directly to the bone. Through the provision of this medical device, Integrum aims to help amputees achieve an improved quality of life. Their evidence-based development has allowed for the creation of an osseointegration limb replacement that allows for improved range of movement. Integrum was officially founded in 1998 and has consistently provided bespoke solutions for amputee patients.
Frequently Asked Questions
The OPRA system is intended for use in any of the finger joints, as well as the Carpometacarpal Joint (CMCJ).
The process of surgically inserting the OPRA® system components into the bone at the amputation stump can be completed in a single session. Although it can sometimes be necessary for two rounds of surgery.
