Abstract：
:This paper gives a general introduction to the terminology, concepts, and classifications of external fixators. A clear distinction is made between characteristics typical of the three types of external fixators, simple, clamp, and ring, and those typical of the four standard frames that can be built with each of the devices. These four frames, the one-plane unilateral, two-plane unilateral, one-plane bilateral, and two-plane bilateral configurations, differ in the ease of wound access they allow and their mechanical balance, particularly toward bending moments. Hybrids of different devices and frames may prove beneficial for stabilizing complex injuries.

杂志文章abstract：:Fractures of the femur in two women, ages 17 and 27, were treated with Brooker-Wills nails. While the distal deployment device was inserted into the nail in one patient, the tip of the driver/inserter broke into the proximal end of the distal deployment device. This complicated the extraction of the nail and the dista...
