This test method aims to test the mechanical properties of aneXpert 2600 angled fixation device not the material component. Angled Fixation Devices are used to treat fractures.

Annex 1 -Single Cycle Compression Bend Testing of Metallic Angled Orthopedic Fracture Fixation Devices

A ramp profile of a compression-bending load is applied simulating the load in the human body.This helps determine the structural properties of the angled fixation device.

Set up according to Fig. A1.2- apply an axial load to lever arm attached to the angled device/plate. The plate is attached to a rigid anchor block support.

  • Use an ADMET eXpert 2600 series Dual Column Testing System. Apply load of increasing magnitude at a constant rate.
  • Use MTESTQuattro to;
  • Calculate compression bending stiffness and strength analysis
  • Plot Load vs. Displacement
  • Plot .2% offset yield on XY  Plot
  • Include statistical summary;high, low, mean, range, standard deviation, +3 -3 Sigma

Annex 2 –Bending Fatigue Properties of Metallic Angled Orthopedic Fracture Fixation Devices.

The angled device is under different angle stress conditions as the bone heals. This test is run for a designated number of cycles. A fixationBending Fatigue device will probably not endure the a large number of cycles, but this test would establish durability and reliability of the product.

  • Determine the bending moment
  • Record number of cycles
  • Typical frequency 5Hz
