Osseointegration Prosthetic Implant System

What is osseointegration?

Osseointegration limb replacement is a surgical procedure where a metal implant is anchored directly to the bone, which then attaches to a prosthesis. The implant then integrates with the surrounding tissue, allowing a new prosthetic limb to be a more natural extension of the body. For patients who have had an amputation, osseointegration can eliminate socket-related issues (redness, blistering, and even ulcers) and can improve quality of life by increasing mobility and function.

The benefits of using osseointegration technology include:

  • Reduction or elimination of pain, skin irritations, ulcers and perspiration
  • Elimination of socket-related problems in traditional prosthetics
  • Increased range of motion and limb strength
  • Increased sense of feel through the prosthesis
  • Intuitive awareness of limb positioning in space
  • Allows for weight gain/loss
  • Comfort during sitting (for lower limbs)
  • Fast and easy donning and doffing of prosthetic

How does it work?

WashU orthopedic surgeons use a system that consists of three parts: an anchoring element, a skin penetrating connection, and a screw to secure both.

Osseointegration surgery is done in one or two phases depending on the implant type, design, and individual patient needs. First, a titanium implant is placed into the bone of the patient’s residual limb during a surgical procedure. As the limb heals from surgery, the implant becomes integrated with the bone, which allows the final prosthetic limb to act more like a direct extension of the limb and body.

After a healing period of about six months, a second surgery is performed so the abutment, or skin-penetrating connection, is attached. A few weeks after the second surgery, rehabilitation begins.

Full weight-bearing on an osseointegration prosthesis is achieved about one year after the initial surgery.

Who is a candidate?

Transfemoral (above-knee) amputee who currently has or is anticipated to have socket issues due to:

  • Recurrent skin issues, such as ulcers
  • Pain
  • Short limb length
  • Scarring/skin grafts
  • Excessive sweating
  • Restricted mobility
