Figure 1d.   (a-c) Turf toe in a 24-year-old professional football player who sustained an acute hyperextension injury at the first MTP joint. (a) Sagittal T1-weighted MR image shows a disrupted plantar plate (arrow) between the sesamoid bone and the base of the proximal phalanx of the great toe. (b) Sagittal short-inversion-time inversion recovery (STIR) MR image demonstrates edema in the region of the plantar plate (arrow). (c) Sagittal STIR MR image obtained adjacent to b demonstrates subchondral bone marrow edema (short arrow) and surface irregularity of the first metatarsal head (long arrow). (d) Intact plantar plate in an asymptomatic 30-year-old woman. Sagittal fat-suppressed fast spin-echo proton-density-weighted MR image shows the plantar plate (long arrow) as a low-signal-intensity band dorsal to the flexor tendons (short arrow).
