1. A dynamic bone fixation element configured to couple a load carrier to bone, the dynamic bone fixation element comprising:
a sleeve that is elongate along a first direction, the sleeve defining a proximal end, a distal end spaced from the proximal end along the first direction, and a channel that extends through the proximal end and toward the distal end along the first direction, the channel having a first cross-sectional dimension measured along a direction that is perpendicular to the first direction, the sleeve further defining an outer surface that is configured to engage bone; and a fixation member having a head, a shaft that extends from the head along a second direction, and an abutment member that extends from the shaft such that at least a portion of the abutment member faces the head, wherein the shaft is configured to extend into the channel such that at least a portion of the sleeve is captured between the abutment member and the head to thereby couple the fixation member to the sleeve, wherein at least a portion of the shaft that is configured to be within the channel has a second cross-sectional dimension along a direction perpendicular to the second direction, the second cross-sectional dimension being less than the first cross-sectional dimension such that the fixation member is moveable with respect to the sleeve along a direction that has a directional component transverse to the first direction, and wherein the abutment member extends from the distal end of the shaft in a third direction that is perpendicular to the second direction, the shaft has an outer perimeter that extends from the head to the abutment member, and the shaft is solid around the outer perimeter. |
