Summary

Lower extremity injuries are frequently encountered in ED and urgent care settings. Lower extremity radiography is useful for the diagnosis of fractures and dislocations of the hip, knee, foot, and ankle, as well as demonstrating pathology of the femur, tibia, and fibula. Plain radiography is helpful in evaluating fractures of the lower extremity bones, as well as masses and malignancies, including pathological fractures. Information obtained from plain radiographs may be limited by several factors. Information obtained from plain radiographs may be limited by several factors such as quality of the technique employed. Penetration of the image and proper patient positioning are crucial to obtaining useful images. As with any radiographic imaging, one must have sufficient knowledge of the normal anatomy to be able to recognize pathology. This includes the ability to distinguish normal variants from true pathology.
