This document describes the design and fabrication of a 3-point bending fixture to assess the strength of heel fracture repairs. Key requirements for the fixture include withstanding a minimum load of 700 lbf while allowing 10 degrees of articulation and adjustable vertical and horizontal supports. Stress analyses were performed to verify the design could withstand expected loads without exceeding yield strengths of the materials. The fixture was fabricated from aluminum and steel components using various fasteners and adjustments. Testing demonstrated it met design requirements and could reliably test calcaneus fracture repair specimens.
