In this paper the subject of fracture treatment shall be limited to a consideration of the principles that apply to the treatment of fractures in general, and of the materials best adapted to their treatment in consonance with these principles.
The term "fracture" as used, implies a broken bone. A bone can be broken, the fragments regain an accurate reapposition and unite without a callus. So that a callus is not necessarily in evidence after a fracture. Manley of New York, a surgeon of vast experience with fractures, has repeatedly observed and noted this fact, termed "primary union." The sine qua non for primary union in a fracture is accurate reapposition of the fragments and fixation. Primary union in fracture is exceptional. It probably occurs only when there is no, or but a very temporary, displacement. Displacement in fractures is the rule. When it persists, there are the genetic factors
