Scanning electron micrographs of a new constraint UHMWPE prosthesis: Recordings at different locations showing the typical cutting traces of the milling treatment. The patterns of milling traces were different at the different sides of the post but showed a very similar appearance at all locations on one side of the post: (a) Location 3, magnification 32×, bar at the bottom correspond to 500 μm. (b) Location 3, magnification 170×, bar at the bottom correspond to 50 μm. (c) Location 4, magnification 32×, bar at the bottom correspond to 500 μm. (d) Location 4, magnification 170×, bar at the bottom correspond to 50 μm. (e) Location 7, magnification 32×, bar at the bottom correspond to 500 μm. (f) Location 7, magnification 170×, bar at the bottom correspond to 50 μm. (g) Location 10, magnification 32×, bar at the bottom correspond to 500 μm. (h) Location 10, magnification 170×, bar at the bottom correspond to 50 μm.
