Patent ID: 8353936

Claim:
A bone stabilization device comprising: a rod having an end portion with an outer radius; a rigid rod receiving member having a bore with an inner radius smaller than the outer radius, such that a press-fit connection is formed when the end portion of the rod is inserted into the bore of the rod receiving member; and wherein one of an outer surface of the end portion of the rod and an inner surface of the bore of the rod receiving member has at least one recess while an entire length of the other one of the surfaces that is configured to be press-fit has a constant cross-section, wherein when the recess is on the inner surface of the bore, a radius of the bore at the recess is greater than the outer radius of the end portion of the rod, and when the recess is on the outer surface of the end portion of the rod, a radius of the end portion at the recess is smaller than the inner radius of the bore, to reduce a contact area at the press-fit connection when the end portion of the rod is inserted in the bore of the rod receiving member.
