2024年8月7日 · Modern prosthetic legs are made of strong but lightweight materials, like carbon fiber or fiberglass, titanium or aluminum. They also have some softer parts, like foam cushioning and silicone sleeves. The moving parts at the joints might include mechanical springs and gears or computer microprocessors.

2023年1月10日 · The prosthesis is a custom-made, porous, coated titanium implant that is aligned with the bone of the residual limb. ( Find a doctor at HSS who performs osseointegration limb replacement.) HSS was the first hospital in the United States to use osseointegration to treat people with transtibial amputations (below the knee).

The OPRA Implant System consists of seven titanium or titanium-alloy parts that are implanted during two surgeries. These parts allow a prosthetic leg to attach directly to the femur (thigh bone). In the first surgery (Stage 1), the fixture is implanted in the femur (thigh bone).

First, a titanium implant is placed into the bone of the residual limb. The implant then extends through the skin and allows for a direct connection to a prosthesis. While healing, the arm or leg implant becomes unified with the bone, which allows the prosthetic limb to act more like a direct extension of the residual limb.

2016年1月12日 · Patient Johnny Matheny tests the Modular Prosthetic Limb attached to a new titanium implant. This is a first for the field of prosthetics, said Michael McLoughlin, chief engineer in APL's Research and Exploratory Development Department.

2016年7月19日 · Typically, amputees cap their truncated limbs with a latex sock and put it straight into a socket. The POP implant removes the need for a socket by surgically inserting a titanium rod into the patient’s femur before attaching a docking station for the new limb. This offers more comfort and range of movement.

With the titanium rod serving as an extension of your existing bone, using an osseointegrated prosthetic attachment has been proven to strengthen the residual limb over time. This is because the natural load of the existing bone is restored as amputees begin using it …

2023年6月1日 · Since the observation that bone could grow onto titanium implants in animal models [11], osseointegrated implants have advanced beyond the field of dentistry to the attachment of prosthetic limbs in human patients.

We found the osseointegration method with titanium implants and skin penetration of the titanium system in patients with leg and arm amputations caused few severe infectious complications.

2023年11月30日 · Titanium is renowned for its exceptional strength, durability, and corrosion resistance. These properties make it an ideal choice for the structural components of prosthetic legs, such as the socket, pylon, and joints.
