ELBOW PROSTHESIS

摘要

A joint prosthesis is provided and may include first and second stem structures and first and second bearing members. The first stem structure may include a generally U-shaped portion having first and second legs. The second stem structure may include first and second bearing surfaces. The first bearing member may be removably coupled to the first leg and may include a first laterally facing bearing surface rotatably contacting the first bearing surface. The second bearing member may be removably coupled to the second leg and may include a second laterally facing bearing surface rotatably contacting the second bearing surface. The first laterally facing bearing surface may be disposed between the first leg and a first lateral side of the second stem. The second laterally facing bearing surface may be disposed between the second leg and a second lateral side of the second stem. The second lateral side may oppose the first lateral side.
