The elongation refers to movement or situation where increased mass longitudinally of a structure, ie a material, object or element conformant a suffers system stretching process finds occurs, this term can be used in different areas.
In medicine, a type of stretch can be identified in bone tissue; bone elongation is a surgical therapeutic method aimed at correcting congenital malformations, exponentially lengthening the bones that make up an area of the body. To achieve this, a technique called "corticotomy" is used, characterized by dividing the modified bone into several parts, that is, fracture the bone to be elongated, later a location is made where the ends of the bone fragments are at a distance apart, in order to generate bone tissue between each space and thus increase the bone length.
Another area where the word elongation is appreciated is in astronomy, when it speaks of elongation it refers to an increase in the distance between the sun and a planet that can be seen from the earth as mercury or Venus; the elongation can be identified according to the visibility of the neighboring planet, if a planet is visible from the earth after sunset or sunset, its elongation is eastern, on the contrary if the planet is evidenced at sunrise its elongation takes place in the western area.
