A staple apparatus can include a base member substantially coplanar to a first axis and a second axis perpendicular to the first axis. The base member can include a trapezoidal shape including two substantially equal length sides and two unequal length sides, the two unequal length sides comprising a first side and a second side with the first side being shorter than the second side and the first side being parallel with the second side on the first axis. The base member can include an aperture passing through a center point of the base member, a first indentation in the first side, and a second indentation in the second side. The staple apparatus can include a first pair of legs protruding from the first side of the base member and a second pair of legs protruding from the second side of the base member.
