What osseointegration is…
The technique consists of mechanical and functional coupling between the amputated limb bone and an artificial prosthesis with titanium components without the presence of connective tissue. Thanks to today’s technologies, osseointegrated implants are better and can be further enhanced in the future.
The osseointegration technique has been proposed as an alternative solution to traditional prosthetic methods and microsurgical techniques to rebuild segments following amputations and/or malformations. This technology will help people who for technical and/or physical reasons cannot wear traditional prostheses, greatly improving their dignity and quality of life.
Many prostheses require a cup-shaped socket to be attached to the stump of the amputated limb. But the amputated limbs of some people are shorter than others and therefore cannot exploit the traditional connection.
Osseointegration solves this problem by allowing a direct connection to the amputated limb bone.
The main problems related to the use of traditional prostheses are related to the area of contact with the skin and intensify as the level of activity of the patient increases. An osseointegrated prosthesis instead avoids these problems and allows the amputee to use the prosthesis for a longer period of the day.
Who the possible candidates are…
This type of prosthesis is optimal for patients with a particularly small residual limb, in which case it is difficult to connect a prosthesis by means of reservoir.
There were also improvements related to the amplitude of the movements that an osseointegrated prosthesis provides compared to a socket-type prosthesis. This can be translated as greater ease and freedom in movements (such as a simple walk for trans-femoral amputees).
