Bone anchor assemblies
First Claim
Patent Images
1. A bone anchor assembly comprising:
- a bone anchor having a proximal head and a distal shaft configured to engage bone, the distal shaft having a shaft diameter and a longitudinal axis; and
a receiving member for receiving a spinal fixation element to be coupled to the bone anchor, the receiving member having a first section having a first bore defining a first bore axis, a recess in communication with the first bore, the recess being sized and shaped to receive a spinal fixation element, and a second section having a second bore defining a second bore axis and being sized to receive at least a portion of the bone anchor, the second section being movably connected to the first section to facilitate relative motion of the first section and the second section.

Abstract
A bone anchor assembly may include a bone anchor having a distal shaft configured to engage bone and a proximal member. The proximal member may have a first section and a second section coupled to at least a portion of the bone anchor. The second section may be movably connected to the first section to facilitate relative rotation of the first section and the second section.

18. A bone anchor assembly comprising:
-
a bone anchor having a distal shaft configured to engage bone; and
a proximal member having a first section having a first opening that defines a first plane, and a second section coupled to at least a portion of the bone anchor, the second section having a second opening defining a second opening that defines a second plane that intersects the first plane, the second section being rotatably connected to the first section to facilitate relative rotation of the first section and the second section.

19. A bone anchor assembly comprising:
-
a bone anchor having a proximal head and a distal shaft configured to engage bone, the distal shaft having a shaft diameter; and
a receiving member for receiving a spinal fixation element to be coupled to the bone anchor, the receiving member having a first section having a first bore having a proximal opening, a recess in communication with the first bore, the recess being sized and shaped to receive a spinal fixation element, and a second section having a second bore having a distal opening and being sized to receive at least a portion of the bone anchor, wherein a diameter of the distal opening of the second bore is greater than a diameter of the proximal opening of the first bore. - View Dependent Claims (20, 21)
