Orthopaedic implant and system

An orthopaedic implant comprising:

• (a) a body for connecting to an intramedullary nail, wherein said body has a proximal end and a distal end, wherein said proximal end and said distal end define a first longitudinal axis therebetween;
• (b) a first aperture at said proximal end of said body for receiving an interlocking screw;
• and
• (c) securing means at said distal end of said body for securing said orthopaedic implant to said intramedullary nail;
• wherein said orthopaedic implant comprises a series of slits on said body, wherein each pair of slits defines a series of deformable leaf layers comprising at least a first leaf layer, a second leaf layer and subsequent leaf layers, wherein each of said first leaf layer, said second leaf layer and said subsequent leaf layers is deformable between a first position, a second position and an actuating position;
• and
• wherein, in said first position, there is no engagement between said leaf layers;
• in said second position, there is engagement between said leaf layers when a first force is applied, which deforms a leaf layer from said first position to said second position;
• and, in said actuating position, there is engagement between said leaf layers and movement of said first leaf layer, said second leaf layer and/or said subsequent leaf layers when a second force is applied, which deforms a leaf layer from said second position to said actuating position.
