Trench foot
Trench foot can be prevented by keeping the feet clean, warm, and dry. It was also discovered in World War I that a key preventive measure was regular foot inspections; soldiers would be paired and each made responsible for the feet of the other, and they would generally apply whale oil to prevent trench foot. If left to their own devices, soldiers might neglect to take off their own boots and socks to dry their feet each day, but if it were the responsibility of another, this became less likely. Later on in the war, instances of trench foot began to decrease, probably as a result of the introduction of the aforementioned measures; of wooden duckboards to cover the muddy, wet, cold ground of the trenches; and of the increased practice of troop rotation, which kept soldiers from prolonged time at the front.
Schilling tendon procedure
The procedure involves the placement of three sutures through the skin anterior to the path of the peroneus brevis tendon and into the underlying deep connective tissue. These sutures provide a temporary barrier, preventing the tendon from moving anteriorly over the malleolus. This procedure was first tested on a cadaver to establish if the surgery would work or not. The procedure is performed with local anaesthetic, about 24 hours before the player begins to pitch. The stitches must be removed immediately following the cessation of play, and indications are that the stitches may tear during the course of a game.
