Abstract
A bone anchor assembly may include a fixation member securable to a bone, a coupling member, a compressible member and a locking member. The fixation member may be formed monolithically with the coupling member, and the coupling member may have a loop portion shaped to receive the compressible member. The compressible member may comprise a compressible sphere with a bore extending therethrough, the bore shaped to receive an elongated member. The locking member may be actuable through an aperture in the coupling member to urge compression of the compressible member to lock the elongated member in a fixed position. The compressible member may be polyaxially adjustable relative to the coupling member.
