Patent ID: 8758345

Claim:
An hour-glass interlocking nail having a flexible, non-rigid geometry, comprising: a. a proximal section, a mid section, and a distal section, each of said sections of said interlocking nail having a diameter and said proximal and distal sections each having a diameter larger than the diameter of said mid section so that said interlocking nail has an hour-glass geometry; said proximal, mid and distal sections each having a solid cross-section, where said cross-sections are to be taken along a transverse plane through the proximal, mid and distal sections, aligned with the respective diameters of said sections; and said interlocking nail having a solid construct; b. the diameter of said interlocking nail gradually decreasing in size from said interlocking nail's proximal section to said interlocking nail's mid section; c. the diameter of said interlocking nail gradually increasing in size from said interlocking nail's mid section to said interlocking nail's distal section; d. said mid section having a first, second and central diameter creating a narrowed center point forming a smooth curve extending from said proximal and distal sections, said center point located at said mid section so that said proximal section and said distal section are virtually tapered cones increasing in diameter on both sides of said narrowed center point, wherein said interlocking nail is appointed to flex at said center point yielding said non-rigid geometry; e. at least one fixation aperture located within said proximal section, and at least one fixation aperture located within said distal section; f. said first and second diameter of said mid section being larger than said central diameter of said mid section; g. said proximal section comprises a proximal end, and said proximal end comprises a connector adapted to be utilized for insertion and alignment of said hour-glass interlocking nail into a bone canal; and h. the solid cross-section of said mid section being without slots or tubes therein and being adapted to flex when said hour-glass interlocking nail is inserted into a bone canal having a curved geometry.
