Risk analysis is in reality a very complex subject. Since risks involve human being, analysis of risks will be as complex as the individual itself, group and societal behavior at hand [1]. This leads to risk determination. It is a process that involves both risk identification and risk estimation. Risk estimation itself is basically a two-step process. The first part deals with the determination of the probability of the event and the second part deals with consequences of occurrence of the event. This paper deals basically with defining the risk of damage to a lumber spine and the quantification of risk. The physical aspects of the lumber spine are very well explained by Bogduk and Twomey [2], McGill [3] and Adams et al [4]. It is essential to know the actual forces in the lumbar spine along with the strength of the lumber spine to define the corresponding probability of failure. This probability of failure will then be connected to the safety index and then to risk index. This paper is an extension of the work done by the authors in this area [5] dealing with determination of forces and the connected guy wires in the sense that the corresponding risk values are calculated in this paper.
