The load at clinically relevant failure of a 6-wrap Softcast forearm splint was 504N in 4 point bending, 202N in 3 point bending (kinking), and 11Nm in torsion (equalling 30.4%, 26% and 42.2% of the equivalent values for a circumferential 4-wrap POP). The 6-wrap Softcast was however stronger in all modes than a fibreglass-reinforced Softcast splint (previously recommended for acute fractures)
