Orthopedic implant for multi-fragmentary fracture of radial head of radius bone and method of implanting the orthopedic implant

An orthopedic implant, especially for a multi-fragmentary fracture of the radial head of a radius bone, said implant comprising an implant body of generally circular shape configured to be in engagement with a nail having an elongated body received within a blind medullary canal of the radius bone, comprising:

• a template device is provided around the radial head of the radius bone to form the restored anatomy structure of the fragments of the multi-fragmental fracture of the radial head,
• the implant body being a truncated cone having a sloping cone-shaped wall provided with a plurality of first through-holes along the wall, the bottom of the truncated cone provided with a central portion,
• the nail having a tip being in engagement with the central portion of the bottom of the truncated cone, and
• a plurality of first fasteners passing the first through-holes in direction from the inner surface of the cone-shaped wall towards the outer surface of the truncated cone for securing the arranged fragments of the radial head to said truncated cone.

A method for implanting an implant for a multi-fragmentary fracture of a radial head of a radius bone, the method comprising the following steps:

• extracting and arranging fragments of the multi-fragmental fracture of the radial head into the form of the restored radial head,
• providing a template device having a bottom surface,
• transferring the restored radial head to a template device configuration such that the top surface of the restored anatomy of the radial head is positioned towards the bottom surface of the template device;
• providing a nail, said nail defined by an elongated body and a tip provided at the top end of the nail;
• and
• reaming the portion of the medullary canal of the radius bone to predict the diameter of the nail;
• providing a truncated cone having a sloping cone-shaped wall provided with a plurality of first through-holes along the wall, the bottom of the truncated cone provided with a central portion,
• reaming the restored anatomy of the radial head by using a reamer to create a space for truncated cone,
• inserting the truncated cone into the created space;
• providing a plurality of first fasteners;
• inserting the first fasteners into the first through holes towards the outer surface of the truncated cone for securing the restored anatomy of the radial head to the truncated cone;
• engaging the tip with the central portion of the bottom of the truncated cone, and
• inserting the nail in the proximal portion of the medullary canal of the radius bone.
