Since 2009, surgeon Dr. Frölke and rehabilitation Dr. Van de Meent have followed all the patients that they have treated with an osseointegration prosthesis. They have investigated the risks and benefits of an osseointegration prosthesis. Initially it was thought that an implant that protrudes through the skin would give rise to infection of the bone and loosening of the implant. From this study in the first 84 patients with an osseointegration prosthesis, the risk appeared to be very small. The implant loosening was 2% and in these cases the implant had to be replaced. Stoma irritation and stoma infections did occur, especially in people who smoke and people with a high body mass index. The stoma complaints appeared easy to treat and are often short lived. Due to recently developed new surgical techniques, the stoma problems are rare and the symptoms are less severe.
What are the benefits of an osseointegration (click) prosthesis?
The advantages of the osseointegration (click) prosthesis compared to a socket prosthesis appear to be very high after the first year of surgery. Research on the first 24 patients treated by the AOFE Clinics team in the Netherlands showed that the time of prosthetic use increased by 80%, the walking distance increased by 32% and walking energy was reduced by 18%. The quality of life increased by 62% and the X-ray examination of the bone showed that the bone of the residual limb became stronger and thicker. A major advantage of the osseointegration prosthesis is that the prosthesis is directly attached to the bone. This makes people feel more comfortable in day to day life, including unrestricted walking, sitting and standing. The benefits are no restriction to daily activities from socket rubs, perspiration or weight fluctuation which has a positive impact on the quality of life. Another interesting advantage is that people with an osseointegration prosthesis can feel the surface under foot.. The vibrations in the prosthesis that occur when walking over a smooth or rough surface are detected in the bone via the implant. This phenomenon is called osseo-perception (feeling through the bone) and gives the person with an osseointegration prosthesis the feeling of having his or her own leg back again.
