From: An intra-bone axial load transducer: development and validation in an in-vitro radius model
Alignment of the servo-hydraulic actuator with the anatomical long-axis of the radius. Zero degree applied load direction (a). The anatomical long-axis alignment of 40° to the servo-hydraulic actuator (b). Note that the radius was tested at angles of 10º, 20º, 30º and 40° and four rotations of the radius for net loads in the anterior, posterior, medial, and lateral directions
