Direct Bone Attachment / Osseointegration
Osseointegration is a new method of attaching the artificial limb to the body. This method is also sometimes referred to as exoprosthesis (attaching an artificial limb to the bone), or endo-exoprosthesis.
The stump and socket method can cause significant pain in the amputee, which is why the direct bone attachment has been explored extensively. The method works by inserting a titanium bolt into the bone at the end of the stump. After several months the bone attaches itself to the titanium bolt and an abutment is attached to the titanium bolt. The abutment extends out of the stump and the artificial limb is then attached to the abutment. Some of the benefits of this method include the following:
- Better muscle control of the prosthetic.
- The ability to wear the prosthetic for an extended period of time; with the stump and socket method this is not possible.
- The ability for transfemoral amputees to drive a car.
The main disadvantage of this method is that amputees with the direct bone attachment cannot have large impacts on the limb, such as those experienced during jogging, because of the potential for the bone to break.

Famous quotes containing the words direct, bone and/or attachment:
“Art need no longer be an account of past sensations. It can become the direct organization of more highly evolved sensations. It is a question of producing ourselves, not things that enslave us.”
—Guy Debord (b. 1931)
“I wonder, Mr. Bone man, what you’re thinking
of your fury now, gone sour as a sinking whale,
crawling up the alphabet on her own bones.”
—Anne Sexton (1928–1974)
“The English, besides being “good haters,” are dogged and downright, and have no salvos for their self-love. Their vanity does not heal the wounds made in their pride. The French, on the contrary, are soon reconciled to fate, and so enamoured of their own idea, that nothing can put them out of conceit with it. Whatever their attachment to their country, to liberty or glory, they are not so affected by the loss of these as to make any desperate effort or sacrifice to recover them.”
—William Hazlitt (1778–1830)
