dc.description.abstract | Objectives: The current biomechanical work compares the symphyseal and sacroiliac stability obtained with two
systems of bone osteosynthesis. The two methods of fixation compared were the 6-hole suprapubic non-locked
plate and pubic fixation with two cannulated screws, a novel technique that can be applied percutaneously in the
clinical practice. The aim of this study was to examine the validity of the use of two-cannulated-screws
osteosynthesis in order to minimize the secondary effects of open fixation, especially in patients in whom an open
reduction is contraindicated.
Materials and methods: A biomechanical study was designed in 9 fresh, human pelvis specimens, simulating an AO
B1.1 type injury, using both fixation systems sequentially in each specimen. In both parts of the test, the specimens
were subjected to an axial load of 300N. Displacements and rotations between the different pelvic elements were
studied by means of a discrete set of points. The absence of differences between the two systems has been set as
the null hypothesis.
Results: There were significant differences in favor of the cross-cannulated screws in most of the displacements
measured at the pubic symphysis and sacroiliac joint.
Conclusions: Fixation of the AO B1.1 type fractures with cross cannulated screws restores the biomechanical
behavior of the pubic symphysis, obtaining better stability than fixation with the 6-hole non-locked plate. To date,
no comparative, biomechanical studies have been conducted with these two systems of osteosynthesis. This study
demonstrates that cross-cannulated screws fixation of the pubic symphysis in AO B1.1 pelvic fractures should be
considered as an alternative to the conventional plating system. | es |
