Abstract
A stemmed implant comprises a proximal body with a distal shaft extending from the proximal body. The proximal body exterior may be spherical, conical, cylindrical, or another surface of revolution. The distal shaft comprises multiple longitudinal ridges which may originate from the proximal body as separate columns, or which may merge together. The distal shaft and/or the ridges may become narrower as they extend away from the proximal body.
