is a spectrum of exercise-induced stress injury of the medial to distal tibia. There are two types Medial (posteromedial) tibial stress syndrome: the most

injures the nearby common peroneal nerve. The tibia and fibula are the two bones of the lower leg. The tibia is larger and located more medially and anteriorly;

bone heals perfectly. The ankle joint is made up of the tibia, fibula, and talus (Figure 1). The tibia forms the superior and medial aspects of the joint,
