Use of human nail for reconstruction of the orbital floor: an experimental study in rabbits.

The orbital floor is the thinnest part of the orbital wall, and in 20% of all maxillofacial injuries it is fractured. Autografts, allografts, and alloplastic materials are used in reconstruction, but there is no consensus about which material is the most appropriate. Nail is a semirigid material that is easy to reshape and is not antigenic.

A cause of severe sacral injury, sledding with a plastic bag: Case report.

Introduction: Various injuries are associated with winter sports, of which the most frequently encountered are traumas to the extremities. Sledding on hills using plastic-based materials appears to be one of the major forms of entertainment for children living in cities during winter. However, this can lead to injury because such areas are inappropriate for winter sports.
