An intramedullary device includes an intramedullary nail (9) extending along a longitudinal axis from a proximal end to a distal end, a proximal portion of the intramedullary nail including a cavity (14) extending from an opening at the proximal end along the longitudinal axis and a locking hole (15) extending transversely therethrough along with a first insert (2) sized and shaped for insertion into the cavity along the longitudinal axis thereof and including a transverse bore (20) aligning with the locking hole and a second insert (3) for engaging an inner surface of the cavity proximally of the first insert to retain the first insert within the cavity and including a central bore (30) extending longitudinally therethrough for coupling to an insertion instrument. |
