1. A bone anchor assembly, comprising:
a bone anchor;
an auxiliary bone anchor;
a receiver member coupled to a proximal end of the bone anchor and defining a rod seat configured to receive a rod;
a closure mechanism threadably mated to the receiver member;
a wing that includes a proximal portion, a distal portion, and a spanning portion that connects the proximal and distal portions, the proximal portion having a distal-facing surface that opposes a proximal terminal end of the receiver member and defines an opening through which at least a portion of the closure mechanism is disposed, the spanning portion extending vertically along a side wall of the receiver member between the proximal portion and the distal portion, the distal portion extending outward from a distal end of the spanning portion; and
a nut configured to threadably engage the closure mechanism to secure the proximal portion of the wing to the receiver member,
wherein the distal portion of the wing defines a bone anchor opening through which the auxiliary bone anchor is disposed, and wherein a distal surface of the distal portion of the wing is obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction,
wherein a proximal surface of the distal portion is distal to a distal surface of the proximal portion.
