The classic "blowout fracture" is the result of a blow to the anterior orbit, which increases retroglobar pressures thus breaking the weakest portion of the bony orbit, the medial floor.

Objective To explore the diagnosis and treatment of the fracture of posterior medial tubercle of the talus (PMTT).

The periosteum near linea aspera should not be stripped during operation on super medial femur fracture to avoid damage on superior nutrient artery.
