Bone Fixator Anatomy of long bone.  Anatomy of the long bone
(1/2)  Human skeletal system consists of bones, Figure 1. Bone
is partly organic (cells and matrix) and partly inorganic
(mineralised component). There are four types of bones: long,
short, flat and irregular. Long bones, especially the femur and
tibia, are subjected to most of the load during daily activities
and they are crucial for skeletal mobility.  Human skeleton and

and long bone definitions.  Long bones have four main functions.
The first function is structural. Bones provide the shape for
our bodies and host vital organs. Body locomotion is the second
function of the bone. The complicated kinematic skeletal system
enables movement, using muscles that control bone positions and
orientations. Bones transmit loads and act as levers. Joints are
the fulcrums about which bones move. Therefore, the prime
qualities of bones are strength and rigidity [1]. Once the load
exceeds the capaci
