Biomechanical testing of unstable humeral shaft fracture plating.

This study compared the biomechanical performance of 4.5-mm limited-contact dynamic compression plates (DCPs) and 3.5-mm locking compression plates (LCPs) for the fixation of unstable humeral shaft fractures.

Exchange femoral nailing: a new technique for removal of a broken nail.

Exchange femoral nailing is the preferred method for treating femoral nonunions. When the index femoral nail is broken, the difficulty of exchange nailing increases dramatically. In this article, we describe a new technique for removing a broken retrograde nail--advancing it out of the proximal end of the femur.

Unicameral (simple) bone cysts.

Since their original description by Virchow, simple bone cysts have been studied repeatedly. Although these defects are not true neoplasms, simple bone cysts may create major structural defects of the humerus, femur, and os calcis. They are commonly discovered incidentally when x-rays are taken for other reasons or on presentation due to a pathologic fracture.
