摘要：

A bone anchor includes a distal bone engaging portion, a proximal portion extending from the distal bone engaging portion that includes a thread profile, and a mating element that threadingly engages the thread profile of the proximal portion. A retention feature between the mating element and the proximal portion deformably engages at least one of the mating element and the proximal portion to resist the mating element from moving relative to the proximal portion of the bone anchor.
