Abstract

An experiment was conducted to determine the influence of anterior cervical plates on multi-level strut-graft loading mechanisms in vitro. Four fresh cadaveric cervical spines were harvested and radiographed and were biomechanically tested in four sequential conditions: harvested (H), (C4-C6) corpectomy (C), strut-grafted (SG), and SG with anterior cervical plate (SGP). Following corpectomy testing, the spine was decompressed and a force sensing strut graft (FSSG) was inserted. The plated spine included an Orion plate attached between C3-C7. Attachment of plate caused an immediate increase in the FSSG load. During flexion of the SGP spine, the FSSG load decreased. However, extension increased the FSSG load.
