An implant for insertion into a joint between articulating bones is provided. The implant includes a generally cylindrical metal body having a plurality of threads disposed thereon. The implant also includes a smooth polymeric portion that is configured to be disposed between the articulating bones of the joint. The polymeric portion provides a bearing surface for the articulating bones, and thus inhibits friction and irritation of the joint tissue. A pin is axially disposed through the polymeric portion and through the body and provides an attachment feature to facilitate rotation of the implant and engagement of the threads within the joint.
