Puncture resistance BS 4812 1972 (93) ISO 3036. A triangular pyramid puncture head is attached to a pendulum. It is released to swing onto a test piece. The energy required to force the puncture head right through the piece, i.e. to make the initial puncture and to tear and bend open the test piece, is measured.

Fig. 10.71. Caput ulnae syndrome in rheumatoid arthritis. Schematic drawing of a transverse view through the distal radioulnar joint outlines the rupture of the triangular fibrocartilage (arrowheads) and marginal erosions at the distal radio-ulnar joint level due to intra-articular pannus (asterisks). As a result, the ulna subluxes dorsally (gray arrow). Pannus (star) inside the extensor carpi ulnaris tendon (open arrow) sheath leads to cortical erosions, tear of the retinaculum and tendon thinning and splitting. St, styloid of the ulna Rad, radius...

Fig.10.77. Triangular fibrocartilage tear. Coronal 12-5 MHz US image over the ulnar aspect of the wrist in a patient with a proved communicating tear of the triangular fibrocartilage at CT arthrography demonstrates a well-defined hypoechoic cleft (curved arrows) within the hyperechoic fibrocartilaginous tissue lying between the triquetrum and the ulna, consistent with a tear. Open arrow, distal radius...
