BIOMECHANICAL ANALYSIS OF SPİNAL İNSTRUMENTATİON FOR LUMBAR BURST FRACTURES
Journal Title: Journal of Turkish Spinal Surgery - Year 1994, Vol 5, Issue 4
Abstract
The goal of this siudy ıvas to assess of axial stiffness of several Alıcı Instrumentation procedures. Compres-sive axial stiffness were measured in eight calf lumbar spines at the Middle East Technicaİ University. A corpecto-my ıvas performed to simulate a burst İnjury, One calf spine was tested intact The tested construct pattem were: corpectomy model v/ithout instrumentation (ICM); upper and lower hookpattem (HPI); upper claw and lower hook pattem (CPI); upper claw with lowerpedlcle screws (CTPI); short segment pedicie instrumentation (SPI). İn addi-tion to tests performed for CTPI and anterlor instrumentation with anterior strut grafts (CTPIG, AIG) ıvere em-ployed. These anaiysis showed that the stlffest construct was the posterior instrumentation with anterior strut (CTPIG). İn addition to these findings cfawpattern andpedicle screws were found to be the best bone-metal con-nectlons.
