Claim Text:
1. A bone fixation device comprising: an elongated body having a proximal end having a head portion and a distal end, the elongated body extending from the proximal end of the head to a shaft at the distal end along a central longitudinal axis, wherein the head portion has a larger diameter than the shaft portion and the head portion is adapted to seat against a structure to define a limit to which the shaft may be inserted through the structure; a slotted opening extending distally from the proximal end into the head by a predetermined distance, the opening defining a spring portion on a lateral side thereof, the spring portion being biased toward the central longitudinal axis and configured to be deflectable away from the central longitudinal axis upon application of a radially expansive force thereto; and a recess extending distally into the head from the proximal end, the recess being configured and dimensioned to engage a driving mechanism and to permit the driving mechanism to pivot with respect to the central longitudinal axis of the bone fixation device without causing pivotal movement of the bone fixation device, wherein the driving mechanism comprises a shaft having a substantially spherical tip at a distal end thereof, and the substantially spherical tip comprises a plurality of circumferentially disposed facets.
