In-Vitro Orthopaedic Research

In-Vitro Orthopaedic Research

  • Define world and local segment coordinate systems consistent with your needs.
  • Instrument multi-segment cadaver specimens to track virtual joint centers, insertion points and other landmarks.
  • Track forces applied by MTS and Instron Machines or loads applied to ligaments together with resultant segment motions.
  • Analyze segment motions pre and post surgical interventions.
  • Register CT/MRI scans of bone surfaces or use The MotionMonitor® Mesh Generator to digitize disarticulated bone geometry. Create wire frames or mesh files.
  • Play back the activity to animate the mesh files in the detail window to observe the interaction of bone surfaces.
  • Export mesh file, kinematic and kinetic data to popular Finite Element Modeling software.

Above, a "sawbone" spine specimen is instrumented with Ascension MiniBirds in an MTS machine. Below, the specimen is instrumented with Metria MPT markers. The world axes and vertebral bodies’ local coordinate axes are then defined by a digitizing process in The MotionMonitor® software, which synchronously captures, processes, and plays back orientation & position data of the vertebral bodies, such as 3D joint angles and changes in joint space. The setup gives the researcher control and flexibility during setup & analysis, allowing users to follow standardized protocols, run multiple projects simultaneously, and utilize student resources efficiently.
