Introduction: An avulsion fracture is where a fragment of bone is pulled away at the ligamentous or tendinous attachment. It can be caused by traumatic traction (repetitive long-term or a single high impact traumatictraction) of the ligament or tendon. This occurs as tendons can bear more load than the bone. It can occur at numerous sites in the body, but some areas are more sensitive to these types of fractures than others, such as at the ankle which mostly occurs at the lateral aspect of the medial malleolus or in the foot where avulsion fractures are common at the base of the fifth metatarsal, but also at the talus and calcaneus
