Femoral fracture risk in transfemoral amputees with bone-anchored prosthetic limbs during activities of daily living.

ABSTRACT:

Background

Bone-anchored prostheses (BAPs) address many of the shortcomings of socket prostheses, driving the adoption of the technology for lower limb amputees. However, higher femoral fracture rates have been observed in these patients compared to socket users. It is believed that this increased fracture rate is due to the direct transmission of loads to bone through the bone-anchored implant. While low-impact activities, such as walking, have been extensively studied using finite element (FE) models, other more demanding low-impact activities such as ambulating on stairs and inclines remain poorly understood. Most previously reported subject-specific FE models of femurs fitted with osseointegrated implants were not validated against experimental data. The current study aimed to
