Device for Measuring the Degree of Bending of an Intramedullary Nail

A system, comprising:

• a device for measuring a degree of bending of the intramedullary nail, comprising:
• a probe sized and shaped for insertion into a cannulation of an intramedullary nail, the probe including a first longitudinal element extending along a longitudinal axis from a distal end to a proximal end and a second longitudinal element extending along a longitudinal axis from a distal end to a proximal end, the distal ends of the first and second longitudinal elements attached to one another so that the longitudinal axes of the first and second longitudinal elements extend substantially parallel to each other and define a middle plane;
• and
• a measuring element measuring relative axial displacement of the proximal ends of the first and second longitudinal elements in the middle plane upon bending of the first and second longitudinal elements as the probe is inserted into a cannulation of the intramedullary nail;
• and
• an aiming device including an extension arm that is adjustable to correspond to a measured relative axial displacement of the proximal ends of the first and second longitudinal elements, the aiming device including a guide bore which, when the aiming device is adjusted, aligns with the locking hole of the intramedullary nail.
