The direct transfer of loads demands that the percutaneous implant system and the residual bone withstand all forces and moments transferred from the prosthesis. This study presents load measurements recorded at the bone-anchored attachment in 20 individuals with unilateral transfemoral amputation performing the everyday ambulatory activities: level ground walking, stairs ascent\/descent and slope ascent\/descent. Mean peak values for the sample populations across activities ranged from 498\u2013684 N for the resultant force, 26.5\u201339.8 Nm for the bending moment, and 3.1\u20135.5 Nm for the longitudinal moment. Significant differences with respect to level walking were found for the resultant force during stairs ascent, (higher, p = 0.002), and stairs descent, (lower, p = 0.005). Using a crutch reduced the peak resultant forces and the peak bending moments with averages ranging from 5.5\u201312.6 % and 13.2\u201315.6 %, respectively. Large inter-participant variations were observed and no single activity resulted in consistently higher loading of the bone-anchored attachment across the participants. Results from this study can guide future development of percutaneous osseointegrated implant systems for limb prostheses and their rehabilitation protocols.","protected":false},"parent":0,"template":"","class_list":["post-1138","research-library","type-research-library","status-publish","hentry"],"acf":[],"yoast_head":"\nLoads at the Implant-Prosthesis Interface During Free and Aided Ambulation in Osseointegrated Transfemoral Prostheses - Center for Bionics and Pain Research<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/cbpr.center\/sv\/research-library\/loads-at-the-implant-prosthesis-interface-during-free-and-aided-ambulation-in-osseointegrated-transfemoral-prostheses\/\" \/>\n<meta property=\"og:locale\" content=\"sv_SE\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Loads at the Implant-Prosthesis Interface During Free and Aided Ambulation in Osseointegrated Transfemoral Prostheses - Center for Bionics and Pain Research\" \/>\n<meta property=\"og:description\" content=\"Bone-anchored attachment of amputation limb prostheses is increasingly becoming a clinically accepted alternative to conventional socket suspension.
