1. A femur fixation device for treating a femur, the femur having an intramedullary canal, a head portion and a lesser trochanter region, the fixation device comprising:
a one-piece elongated nail defining a longitudinal axis with a length along the longitudinal axis, a width perpendicular to the longitudinal axis that extends from a first side of the one-piece elongated nail to a second side of the one-piece elongated nail, and a bore extending through the one-piece elongated nail from the first side to the second side, the one-piece elongated nail configured for insertion into the intramedullary canal of the femur; and a buttress element configured to extend from the one-piece elongated nail and apply a force to bone tissue in or adjacent to the lesser trochanter region of the femur, the buttress element including:
a support member having a distal end; anda reinforcement member, the reinforcement member directly pivotally coupled to the one-piece elongated nail, wherein, at a first position, the reinforcement member is located adjacent to the one-piece elongated nail and is configured to engage with the distal end of the support member such that upon advancement of the support member through the bore, the reinforcement member pivots from the first position to a second position, and wherein, at the second position, the support member extends through the bore with the distal end contacting a surface of the reinforcement member such that a portion of the reinforcement member extends from the one-piece elongated nail. |
