The primary stability of the osteosynthesis association plate fixation on the lower spine 1. the load capacity of the cervical vertebral body






Zeitschrift fuer Experimentelle Chirurgie Transplantation und Kuenstliche Organe 18(2): 87-92

The primary stability of the osteosynthesis association plate fixation on the lower spine 1. the load capacity of the cervical vertebral body

The axial force (twisting moment) leading to breaking of the bony thread, using 3.5 mm cortical-screws at the H-plate-fixation for fracture dislocations of the lower cervical spine, was established by means of 316 measurements performed on cadavers. It comes to 0,8471 mN (8,6360 cmkp). Apparently, the 3.5 mm cortical screw should be tightned with 0,5886 mN (6 cmkp) at the fixation. This force provides primary stability at the H-plate without primary instability due to thread-break.
