“…The area is well circulated because of the attachment of large muscles. Due to good vascular network, the possibility of non-union of fractures is very small [34] [37]. These types of fractures are the most common in elderly people.…”

“…Fractures are categorized as stable and unstable, although not all physicians agree with this classification [37]. In stable fractures, the posteromedial pillar is not injured or minimally shifted and the fragments are stable.…”

“…Bannister et al do not support the use intramedular screws [47]; however, Ackroyd reports of the use of intramedular screws and consequent better stability [36]. Schatzker et al use for type 1, 2, and 3 fractures DHS and for type 4 fractures a dynamic compression screw (DCS) with condillar plate and gamma screw, showing promising results [37]. DHS enables a solid fixation and stable fixation with a plate.…”

The biological tissue is affected by external and internal deformation forces: tractive/tensile forces, shearing and compressive forces. The bone is deformed under the effect of a force. If the load exceeds the bone solidity limitation, fracture occurs. A mature bone consists of compact and spongy bone tissue. The basic structural unit of the cortical bone tissue are osteons and spongiosa consists of a network of bone trabeculae. The organic and mineral parts of the bone are responsible for the special bone characteristics. The effect of a physical activity on the mechanical characteristics of the bone is associated with the intensity of the load. Fractures are more common in elderly people as the bone structure is altered on account of osteoporosis and contains less bone tissue. Biomechanical characteristics with anatomic and histological bone structure as well as osteoporotic hip fractures are described in the paper.
