The radius has a 'D'-shaped proximal end with a flattened rugose articular surface.
Cruciate Retaining Implant With Biomimetic Articular Surface to Reproduce Activity Dependent Kinematics of the Normal Knee.
No articular surface is of uniform curvature; neither is it a "surface of revolution" such as a cylinder is.
The implant, known as the Articular Surface Replacement, or A.S.R., was recalled in mid-2010.
Graft implantation should be flush with the native articular surface.
Of particular difficulty are those fractures involving the articular surface.
Articular Surface Replacement (trademarked hip design).
Articular surface of MM 0.080 n.s.s
Observers were asked to identify displaced fracture fragments, dislocation, and articular surface fractures.
The articular surface was anatomically reduced and was secured with Kirschner wires or screws.
Observer variability in assessing articular surface displacement in acetabular fractures using a standardized measurement technique.
