Signs and Symptoms of plantar plate ruptures
Plantar plate ruptures occur when stress upon the thin structure exceed its threshold and causes a tear. This common condition affects both males and females, and is often seen in individuals who have recently begun an exercise program or have increased the intensity of their workouts too quickly.
Sufferers experience a sharp pain and/or swelling under the ball of the foot extending towards the toes. The pain is most commonly found at the base of the 2nd and 3rd toes and often worsens when barefoot or tip-toeing.
In more severe cases, a visible deformity in the toes may develop, giving the appearance of splayed apart toes. Known as a ‘Daylight Sign’, this is a clinical indication of a plantar plate rupture.
Causes
While the plantar plate is very thin but very strong, the structure can weaken and eventually rupture. Individuals who transfer excessive forces through the forefoot or suffer from overpronation, and those with hypermobile foot or high arch foot types are at an increased risk of rupturing the plantar plate.
Sudden increases in physical activity or changes in fitness activities, such as beginning a fitness program or training for a marathon, can cause symptoms to present and a partial or complete rupture to occur.
