A set screw for use in an intramedullary fracture fixation device having a longitudinal axis includes a housing and a set screw. The set screw may include a body with an external thread and an elastic member extending from the body, the elastic member having an uncompressed condition and a compressed condition. The housing may include a sidewall partially surrounding the longitudinal axis that defines a cavity for receiving the set screw such that when the set screw is at least partially disposed within the cavity and in the uncompressed condition, the set screw is secured to the housing and rotatable relative to the housing.

A combination of an implant () like a bone screw together with an augmentation sleeve () is suggested. The bone screw may comprise a trailing end portion with a plurality of lateral bores (). The augmentation sleeve may comprise a leading end portion which is adapted to be coupled to the trailing end portion of the bone screw, and a lateral opening () at the leading end. The augmentation sleeve may be adapted to guide an augmentation tool to the trailing end portion of the bone screw and to the leading end portion of the augmentation sleeve so that the trailing end portion of the bone screw may be augmented by pressing augmentation material through the plurality of lateral bores at the trailing end portion of the bone screw and further through the lateral opening of the augmentation sleeve into the bone at the trailing end of the bone screw, or other implant. After the augmentation of the trailing end portion of the bone screw, the augmentation sleeve may be removed.
