Osseous Integration is the attempt to improve the interface between the prosthesis and the residual limb. This technique requires a stem be inserted into the bone of the residual limb, and a portion of the stem extends out of the limb.  The prosthesis is connected to the stem.

"Traditional" prosthetics utilize a sleeve over the amputee's residual limb. Then the prosthesis is slid onto the sleeve and connected with a belt or snap device.  The problems that an amputee may encounter with the traditional method are skin breakdown, changes in prosthetic fit due to weight changes of the amputee, and lack of awareness where the residual limb is in space (proprioception).

Osseous integration addresses these problems because there is no sleeve to place over the residual limb so no issues with skin breakdown or weight changes. The prosthesis connects to the bone of the residual limb so there is a better sense of proprioception for the amputee.

Osseous integration is not yet available for people in the US.  It has been utilized in Europe. In addition, it has been utilized for treatment for a dog in Denver that was found in Turkey with both hind legs amputated.  Click on the video links below to see Triumph's progress with her prosthetics.
