We are one of the first dedicated and unique osseointegration programs in the country. Our unique program is dedicated to amputee patients who are experiencing difficulty with their prosthesis. 

What is Osseointegration​​

Osseointegration of the limb is a surgical procedure used for permanent placement of artificial limbs connected to the human skeleton. A metal implant is inserted into the amputated extremity bone. The connector passes through the skin and attaches to the prosthesis.

 Candidates for Osseointegration

  • Pain or irritation such as sores and chafing with your prosthesis socket
  • Difficulty walking, standing, or sitting with your prosthesis socket
  • Sudden loosening or fitting-problems ​​

 Benefits of Osseointegration

  • Improved quality of life
  • Less pain or irritation experienced with socket prosthesis such as sores, chaffing, or sweating 
  • Longer walking distances and better sitting comfort
  • Better stability standing or walking
  • Osseoperception: a more natural feeling; the ability to sense or feel the prosthesis​​

 Osseointegration Process

The evaluation process begins with a clinical pre-screening to determine if you are a candidate for surgery.  In-person screening and testing is scheduled based on pre-screening outcomes.  If osseointegration surgery is right for you, additional baseline testing may be planned and may be sent home with pre-habilitation exercises to improve your strength or flexibility.


The device is implanted into the bone via a two-stage surgical procedure (some patients may have this done in a single stage), 6-8 weeks apart.  The two-stage technique allows for good bone ingrowth into the implant prior to weight bearing.  In the first stage, the length of the bone may be adjusted and the soft tissue is prepared.  The device is implanted and the skin is closed.  You will stay in the hospital for 1-2 days and be non-weight bearing until after the second surgery.


After 6-8 weeks, you will have the second surgical procedure. This procedure is an outpatient surgery with no anticipated hospital stay. A circular opening is made in the skin creating a stoma, to allow for attachment of the external implant component that is secured with an internal locking screw. Within one week after the second surgery, you will meet with a prosthetist and your prosthesis is attached to the external implant component and you will begin walking socket free.​​



Dr. Stoneback believes that rehabilitation plays an essential role in osseointegration success. You will meet with our Physical Medicine and Rehab team at your initial consult and again preoperatively. Rehabilitation is individualized and you can expect three weeks of physical therapy with our team following osseointegration. Once home, we will work with your local physical therapist to ensure post-operative plans are executed.​ ​​5
