Abstract
A pivotal bone anchor system includes a plurality of bone anchors having rounded capture portions with circumferentially extending capture recesses. The system also includes multi-planar receiver sub-assemblies, each comprising a multi-planar receiver defining a cavity with a multi-planar seating surface, and a multi-planar pivoting retainer configured for multi-planar motion upon engagement with the multi-planar seating surface and to snap into a capture recess to capture a bone anchor within the multi-planar receiver. The system further includes uni-planar receiver sub-assemblies, each comprising a uni-planar receiver defining a cavity with a uni-planar seating surface, and a uni-planar pivoting retainer configured for uni-planar motion upon engagement with the uni-planar seating surface and to snap into a capture recess to capture a bone anchor within the uni-planar receiver. The capture portions of the bone anchors are configured for capture by either a multi-planar or uni-planar receiver sub-assembly without further modification or adjustment.
