摘要：
In one embodiment, the present invention includes a bone fixation assembly comprising a coupling element and a bone anchor. The coupling element has an upper surface with a first diameter defining a first bore extending along a first axis, a lower surface with a second diameter defining a second bore extending along a second axis, and an internal surface area defining a seating portion adjacent to the lower surface. The bone anchor has an insertion end opposite of a head. The head may be curved for receipt within the seating portion. The second diameter of the second bore may be greater than the first diameter of the first bore or vice versa. Likewise, the first and second axes may intersect such that the first and second bores are in communication with one another. Related elements and systems of this assembly are also disclosed.
