Case Discussion

Plantar plate tears of the lesser metatarsals, toes 2-5, are usually referred to as plantar plate tears, whereas those affecting the hallux/1st toe, tend to be referred to as a turf toe.  The diagnosis of a complete tear is made when there is complete discontinuity of a portion of the plantar plate, whether the central aspect or the collateral ligaments.
