Comparative Experimental Study of Custom Made Plate for Anterior Stabilization and Dorsal Fixation Systems at C1-C2 Vertebrae Level

Abstract


Experimental study on the evaluation of strength of fixation with metal constructions at the level of C1-C2 vertebrae was performed on the basis of test laboratory for orthopaedic and traumatologic products. Experiments were performed on the cadaver block preparation (4) and plastic models (8) of craniovertebral spine. Authors’ custom made plate, hook system, screw systems by Magerl and Harms were used as fixators. First step was the imitation of the turning of the head to the right (“twisting”), second step - imitation of head tilting forward (“three point pressure”). It was shown that by its strength and stability of craniovertebral segment the elaborated metal plate was not inferior to dorsal fixation systems.
