Definition: Shin splints is the common term for MTSS (Medial Tibial Stress Syndrome) and is described as pain along the bottom 2/3 of the inside aspect of the shin bone. It is a result of inflammation of the 'periosteum' (connective tissue).
Function: There are several muscles, gastrocnemius, soleus, and flexor digitorum longus that originate at the shin border and excessive use by all or some of them can cause damage.
With excessive pronation, certain muscles are in high demand. This overuse of the tendons causes extra stress to the connective tissue at the bone, which is the periosteum.
Custom made Orthotics are a very effective method to reduce your pain. They are able to redistribute and load the foot in a different way in order to decrease stress to the periosteum. Pedorthists use interventions such as medial arch support and deep heel cups to stabilize the foot. Proper footwear is just as important as the orthotic in decreasing your pain. Talk to your Pedorthist about proper footwear choices for you.
