In our paper, we wanted to compare biomechanical effectiveness of the Romadier-Bombart wire stabilization with the Martin hook and rod stabilization. We used 8 human spine specimens and we measured linear and angular displacements under loading, using an Instron testing machine. By applying force in three different positions we simulated extension, flexion, and lateral bending of the specimens. The results of our experiment show that both methods give sufficient and comparable stabilization. We suggest that in clinical practice, because of the technical difficulty of the Romadier-Bombart method, the Martin system should be preferred as the safer.
