Fig 1.
X-ray imaging of the pelvis model with plate osteosynthesis.
a shows the a.p.- view and b the obturator- view of the hemi-pelvis.
Fig 2.
X-ray imaging of the pelvis model with arthroplasty.
a shows the a.p.- view and b the ala- view of the hemi-pelvis.
Fig 3.
Test set-up clamped in the testing machine.
The acetabulum was aligned in a manner that a physiological force introduction was realized according to Bergmann et al.
Fig 4.
Shows the standardized placement of the spackle patterns.
Four different fracture gap displacements were measured. The optical measurement was performed between spackle pattern 1/2, 1/3, 2/3 and 4/5 (1 = os ischii; 2 and 4 = os pubis; 3 and 5 = os ilium).
Fig 5.
Graphs show the fracture gap displacement between the different measuring points as a function of the applied forces during cyclic loading.
Fig 6.
Boxplots compare the maximum failure force of the osteosynthesis and the arthroplasty without significant difference (p = 0.173).
