Figure 5.
(A, B) Gross photographs of a disarticulated wrist sample prepared for biomechanical indentation testing of the distal surface of the TFC disc with a (A) non-porous 1 mm diameter plane-ended indenter. (B) Each TFC disc was tested at multiple sites along a radio-ulnar midline of the disc. (C) Indentation testing protocol consisted of application of a short-duration compressive displacement while measuring the force generated. Differences in measured data from a normal (green) and a degenerated (red) TFC disc is illustrated.
