Common use of Bone Clause in Contracts

Bone. Bone is a dynamic connective tissue consisting of an inorganic and organic phase. Approximately 60% of bone tissue is inorganic matter, 8-10% is water and the remainder is organic matter [1]. The inorganic phase of bone tissue is an impure form of hydroxyapatite (Ca10[PO4]6[OH]2) – a naturally occurring calcium phosphate. The organic phase is predominately made up of type I collagen and a variety of non-collagenous proteins and cells [2]. The structure of bone and its composition reflect a balance between its two major functions; the provision of mechanical integrity for locomotion and protection, and involvement in the metabolic pathways associated with mineral homeostasis [1]. There are two types of bone within the body, cortical and trabecular bone. Cortical bone is dense and compact and forms the outer layer of bone whereas trabecular bone makes up the inner layer of bone and has a spongy, honeycomb-like structure (Figure1.1) Cortical bone constitutes approximately 80% of our skeletal mass and the remaining 20% is that of trabecular bone [3].
