Abstract : Baboons were dropped vertically from four feet above the ground. The vertebral columns were examined with light microscopy and scanning electron microscopy. Six months post-impaction, there was damage to the vertebral end plates and beginning osteoarthrosis of the facet joints. Six years post-impaction, the lesions had progressed to anterior osteophyte formation and severe osteoarthrosis of the facet joints. The lesions observed in this study are thought to be related to the impaction sequence. Normal anatomy of the rhesus monkey spine was also investigated.
