Modular intramedullary nail

Abstract

An intramedullary nail, comprises a proximal portion, a middle portion and a distal portion. The proximal portion has a longitudinal slot and the distal portion has at least one transversal bore. The proximal portion has a longitudinal axis and a longitudinal bore extending over the longitudinal extension of the slot in the distal direction. The longitudinal bore has an internal thread. An insert which is intended to be inserted in the longitudinal bore. The insert comprises a guiding bore in the form of a slot which is intended to receive fixing elements. The alignment of the guiding bore of said insert is transverse with respect to the longitudinal axis of the proximal portion. The insert has a compression screw adapted to be screwed into said internal thread of the longitudinal bore of the proximal portion to move a fixing element in the direction of the longitudinal axis of the intramedullary nail.

1 . An intramedullary nail, comprising: 
 a) 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;    b) the proximal portion having a longitudinal axis and a longitudinal bore extending over said slot in the distal direction, said longitudinal bore having an internal thread; and    c) a hollow insert which is intended to be inserted in said longitudinal bore, said insert comprising at least one guiding bore in the form of a slot which is intended to receive fixing elements;    d) the alignment of the at least one guiding bore of said insert being transverse with respect to the longitudinal axis of the proximal portion;    e) said insert comprising a compression screw adapted to be screwed into said internal thread of the longitudinal bore of the proximal portion and adapted to be inserted in the hollow insert so as to move the fixing element in the direction of the longitudinal axis of the intramedullary nail.
