A plantar plate tear is a smaller tear or strain to the ligament which is under the smaller toe joints in the foot. It is almost always associated with excessive use, especially in exercises that need the toes to be bent back or dorsiflexed. The pain is often just above the region distal to the joint on the bottom of the foot. As this issue is due to the toe bending to much backwards or upwards (dorsiflexing) when walking, taping is an excellent method to limit that movement.
The most effective method for taping a plantar plate tear would be to loop some tape across the toe to tug the toe down in a plantarflexed position. The ends of the strapping go under the ball of the foot and by looping around the toe it will hold it plantarflexed. The concept being is that whenever we walk, and the heel raises up off the ground and the toe flexes there's less load on the plantar plate since the toe is kept from bending back. In this way the plantar plate tear taping can assist the injury heal. This tends to take a while however is usually successful. Different methods may be used to help prevent the dorsiflexion through the joint that is painful, for example with a more inflexible sole footwear that is not flexible since this can prevent a lot of movement in the joints. There's also stiff plates that can be used as insoles to help make the footwear stiffer. A foot support insert which has a hole around the uncomfortable area may also be used for getting weight away from the painful location will likely allow it to be more comfortable to walk on. These sorts of strategies usually are fairly helpful, particularly that strapping. However, as we still need to walk about on the foot rather than get complete rest, it can take a few months of this strategy in order to get a good outcome. It sometimes may not really work out like that or the problem is particularly distressing. In these instances, surgery to mend the tear may well be showed.
