Abstract: A screw assembly and method developed for the fixation of femoral neck fractures without interruption of the growth process is disclosed. The screw assembly includes a male component that is attached to the lateral cortex and a female component that is attached at the proximal epiphysis. Anchorage of the components is achieved through screw-type fixation. The screw has a built-in feature that allows for free extension of its length as the fracture site or the slipped capital physeal plate heals and normal patient growth continues. Stable fixation and rotational stability are created at the fracture (slip) site while avoiding compression forces, thus avoiding premature closure of the physeal plate.

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.
