Bone-anchored prosthesis: Current developments worldwide and challenges

Frossard, Laurent A. (2015) Bone-anchored prosthesis: Current developments worldwide and challenges. XV World Congress of the International Society for Prosthetics and Orthotics (ISPO).



Individuals with limb amputation fitted with conventional socket-suspended prostheses often experience socket related discomfort leading to a significant decrease in quality of life. Most of these concerns can be overcome by surgical techniques enabling bone-anchored prostheses. In this case, the prosthesis is attached directly to the residual skeleton through a percutaneous implant (e.g., screw type fixation, press-fit implant).[46, 48, 51, 52, 77, 78] The aim of this study is to present the current advances in these surgical techniques worldwide with a strong focus on the current challenges.


The current advances will be extracted from a systematic literature review including approximately 40 articles. The outcomes measured will include the estimation of the population worldwide as well as the complications (e.g., infection, loosening, fractures, and breakage) and the benefits (e.g., functional outcomes, health-related quality of life).[5-19, 51-53, 55, 57, 58, 62, 73, 79]


The population of individuals fitted with a bone-anchored prosthesis is approximately 550 worldwide. Publications focusing on infection are sparse. However, the rate of superficial infection is estimated at 20%. Deep infection occurs rarely. Loosening and peri-prosthetic fractures are fairly uncommon. Breakage of implant parts occurs regularly mainly due to fall. All studies reported a significant improvement in functional level and overall quality of life.


Several commercial implants are in developments in Europe and US. The number of procedures is consistently growing worldwide. This technique might be primary way to fit a prosthesis to young and active amputees by 2025.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
