Abstract
A keel for an orthopedic implant with a tray portion. The keel has a wall having a posterior end, an anterior end, and sides that extend from a surface of the tray portion. The wall is at least partially upraised away from the surface of the tray portion at its posterior end to define a posterior keel opening. The anterior end may either merge with the surface of the tray portion or can be spaced away to form an anterior keel opening. The keel can slant downwardly from the posterior end to the anterior end by about 10 to 20 degrees. The wall can have two spaced apart flat side walls and a flat top wall, or can be a continuous curved wall. A bone ingrowth space is defined between the wall and the tray portion. Openings can optionally be formed in the wall for additional bone ingrowth.
