Abstract
A fixation member includes a body portion having (i) an upper surface, (ii) a lower surface, and (iii) a perimeter edge interposed between the upper surface and the lower surface. The fixation member also includes a number of arm members each having a first end and a second end. The first end of each arm member being secured to the perimeter edge such that each arm member extends in a radial direction relative to the body portion. The fixation member further includes a penetration structure secured to the second end of each arm member such that each penetration structure extends in an axial direction relative to the body portion. The penetration structure is configured so as to penetrate below an outer surface of a bone when the fixation member is biased against the outer surface of the bone. The penetration structure is further configured to limit the penetration so that the lower surface of the body portion is prevented from contacting the outer surface of the bone when the fixation member is biased against the outer surface of the bone. An associated stop member is also disclosed.
