Osseous Integration (OI)
Osseous Integration (OI) is an evolving technology in which metallic implants are connected directly into the bone and then come out through the skin to attached to an external prosthetic.
Traditionally, amputees residual limbs are molded to a socket. The socket is then connected to an external prosthetic. This is an acceptable solution from a pain and function standpoint for most amputees. For some, however, use of traditional socket technology is not effective. Issues include: perspiration (causing sockets to fall off), pressure sores, pain, lack of ability to “feel” the ground as one walks, and having to expend a lot of energy to simply achieve every day tasks.
The purpose of OI is to improve pain, function, and energy efficiency for amputees. This technology was first introduced in Europe in the 1990’s and has been used in dental implants as well. The difficulty with this technology has always been the risk for infection. Those who receive OI implants typically have a chronic draining sinus that forms around the skin interface and it is through this sinus that infection can ascend into the bone. If the infection is severe enough, it can loosen the implant from the bone and cause failure.
Dr. Hugate’s interest in this technology started in 2003 when he was deployed as an army surgeon to Baghdad, Iraq and cared for many service members who had suffered traumatic amputations. Upon his return the U.S., while a Fellow at the Mayo Clinic, he began researching a new genre of implant materials termed “highly porous” materials in which skin and soft tissues could actually grow into and seal off implants.
Over the last decade, Dr. Hugate has developed an OI implant that utilizes porous metal technology to help “seal off” the implant and reduce the risk of infection. This technology is still in the early stages of development but has shown promising early results.
Although Dr. Hugate believes that OI will eventually become the standard of care for amputees worldwide, he is only considering a very select group of patients to receive this technology at this time.
Consideration for OIPatients who are candidates for consideration for OI include:
- Patients who have failed use of traditional socket technology
- Between ages of 18-50
- Above-Knee amputees (although other amputee types would be considered)
- No history of active infection
