For many reasons Finite Element Method is very useful especially in biomechanical researches .One of them is difficulty of gaining real specimens for in vitro tests. The second one is that FEM provides relatively easy way to check how changing some parameters of spine geometry or materials, influences on spine segment behavior. Consider it, many research centers in whole world in last years started to prepare FEM models of spine. Some of them are quite simple, some are very advanced. This paper is a review of three chosen FEM lumbar spine models, made in different scientific centers in last years. Authors present their opinions about possibilities of using material coefficients of particular structures of spine in own model. It could be useful for anybody who wants to build proprietary spine model. Authors met many problems trying to obtain material coefficients from literature which may be adopted to own spine model. Models reviewed in this paper could be important assistance for creating own spine models.
