Abstract
An intramedullary nail apparatus comprises a nail having a proximal portion, a middle portion and a distal portion. The proximal portion has a longitudinal slot adapted to receive at least one fixing element and the distal portion has at least one transverse bore. The proximal portion has a longitudinal axial bore. The apparatus further includes a set of inserts, each of which is adapted to be inserted in the longitudinal bore. Each insert has at least one guiding bore, the orientation and position of which is different for each of the inserts. A method of treating fractures utilizing the intramedullary nail apparatus is also disclosed.

An intramedullary nail comprising a nail which is composed of a proximal portion, a middle portion and a distal portion, said proximal portion having a longitudinal slot extending throuqh the proximal portion in a direction transverse to the longitudinal axis of the proximal portion and being adapted to receive at least one fixing element extending therethrough and said distal portion having at least one transversal bore, the proximal portion having a longitudinal axial bore extending over the longitudinal extension of said slot and a set of inserts each of which is adapted to be inserted in said longitudinal bore, each of said inserts comprising at least one guiding bore to receive said fixing element, the orientation and the position of said guiding bore being different for each insert of said set of inserts.
An intramedullary nail comprising a nail (1) which is composed of a proximal portion, a middle portion and a distal portion, said proximal portion having a longitudinal slot and said distal portion having at least one transversal bore, said middle portion and said distal portion of the nail being provided with a wire groove which ends in a wire channel (13A) at the distal end.
A method of treating fractures comprising the steps of:
- (a) placing a nail in the intramedullary space of a bone, the nail having a longitudinal axis and a proximal portion, a middle portion and a distal portion, the proximal portion having a longitudinal slot and the distal portion having at least one transverse bore, whereby the proximal portion includes a longitudinal bore extending over the longitudinal extension of the slot in the distal direction;
- (b) introducing at least one distal fixing screw in the at least one transverse bore;
- (c) selecting an insert from a set of inserts, each of said inserts having at least one guiding bore, the orientation and position of the guiding bore being different for each insert of the set of inserts;
- (d) introducing the selected insert in said longitudinal bore, the insert having at least one guiding bore;
- and
- (e) driving one fixing element in the at least one guiding bore of the insert and through the longitudinal slot of the nail.
