PHYSEAL FRACTURES .2. 2 PREVIOUSLY UNCLASSIFIED TYPES

This article describes two physeal fractures not previously classified . The first is a fracture completely across the metaphysis with extens ion to the physis. There is usually no extension of the fracture along the physis, as is seen with the Salter-Harris type II fractures. It i s a common fracture, occurring in 15.5% of the Olmsted County study. T he second previous unclassified fracture is one in which a portion of the physis is missing. This is always an open fracture, and, thus, alw ays requires initial surgery. It almost always develops premature phys eal closure and almost always requires late reconstructive surgery.
