A polyaxial occipital plate assembly and method comprises a longitudinal member; a polyaxial connector head; a socket portion adapted to retain the connector head; a flexible clip operatively connected to the socket portion and adapted to receive the longitudinal member; an occipital plate comprising clips operatively connected to the connector head; and a locking mechanism operatively connected to the connector head and the clips, wherein engagement of the locking mechanism to the connector head causes the clips to lock into the connector head and outwardly expand the connector head thereby causing the flexible clip to squeeze against the longitudinal member. The plate comprises a pair of opposed legs comprising the clips attached to ends of the legs; a body portion operatively connected to the pair of opposed legs, wherein the body portion is positioned at any of an obtuse and an acute angle relative to the pair of opposed legs.
