Modular intramedullary fixation devices

A modular intramedullary fixation device, comprising:

• a plurality of substantially Z-shaped modular elements, wherein each of the substantially Z-shaped modular elements has a proximal flange and a distal flange, the distal flange of each of the substantially Z-shaped modular elements being secured to the proximal flange of an adjacent one of the substantially Z-shaped modular elements;
• a proximal end piece secured to the proximal flange of a proximal-most one of the substantially Z-shaped modular elements;
• and
• a distal end piece secured to the distal flange of a distal-most one of the substantially Z-shaped modular elements, and
• wherein the proximal end piece and a first portion of the substantially Z-shaped modular elements define a proximal section of the modular intramedullary fixation device, and the distal end piece and a second portion of the substantially Z-shaped modular elements define a distal section of the modular intramedullary fixation device, a maximum width of the proximal section being greater than a maximum width of the distal section,
• wherein the proximal section of the modular intermedullary fixation device further comprises a plurality of substantially Z-shaped modular elements that define a first concave curved surface on the proximal section of the modular intermedullary fixation and a plurality of substantially Z-shaped modular elements that define a first flat surface on the proximal section on the intermedullary device, said first concave curved surface adjacent said first flat surface,
• wherein the first concave curved surface has a starting edge defined by the proximal end piece secured to the proximal flange of the proximal-most one of the substantially Z-shaped modular elements and an ending edge defined by the maximum width of the proximal section,
• wherein the distal section of the modular intermedullary fixation device further comprises a plurality of substantially Z-shaped modular elements that define a second concave curved surface on the distal section of the modular intermedullary fixation and a plurality of substantially Z-shaped modular elements that define a second flat surface on the distal section on the intermedullary device, said second concave curved surface adjacent said second flat surface, and
• wherein the second concave curved surface has a starting edge defined by the distal end piece secured to the distal flange of the distal-most one of the substantially Z-shaped modular elements and an ending edge defined by the maximum width of the distal section.
