Full-scale testing is used to characterize bone biomechanical strength.
Hip Wear Simulator
- The Shore Western Hip Wear Simulator allows simultaneous component wear testing of six acetabular cup and femoral head components under simulated loading as would be experienced during normal locomotion.
- Additionally, six implant constructs can be tested under axial loading only (i.e., no rotational component) and used as soak controls, if desired.
- A number of loading profiles are available for specifying the applied axial load during wear and soak control testing, and the system can be set for cyclic rates of up to 1.5 Hz.
- SwRI maintains numerous facilities that are available to isolate and characterize the spatial distribution of implant wear as well as the resulting particulate.
Musculoskeletal Biomechanics at Southwest Research Institute (SwRI) employs numerous servo-hydraulic and servo-electric materials testing systems to characterize the material and mechanical properties of both biological materials and biomaterials. We have also developed a number of specialized in situ microscopy testing systems that allow high-fidelity imaging of test specimens while undergoing controlled deformation to study the micromechanical behavior of biological tissue, including.
- Creep, relaxation
- Fracture toughness
- Whole bone strength testing
