Abstract

A patient specific shoulder guide is provided that includes a plurality of peripheral members coupled with a peripheral body. The peripheral members have a patient specific contact surface. An open space (e.g., a single open space) is or can be provided radially between a central channel and an inner periphery of the peripheral body. The open space(s) can extend from a side of a spoke to another side of the same or a different spoke. The spoke can be a single spoke in some embodiments. The single open space can extend more than 120 degrees between circumferential ends of the open space.
