Abstract
An intramedullary nail system includes a telescopic nail assembly for use in fixation of long bone fractures. The nail assembly includes a female hollow nail that is attached to the proximal cortex of the femur, and a male solid nail that is attached to the distal cortex. Anchorage of the telescopic nail assembly is achieved through screw type fixation. The intramedullary nail system has a built-in feature that allows for extension of its length as bone structures heal and normal patient growth occurs, which is particularly advantageous to be used for children above two years of age and below 65 kilograms of body weight.
