Abstract
This paper describes a procedure of activating osteogenesis by the use of the "petal" technique. The osteogenetic effect of these "petals" has been established in experimentally produced fractures and pseudarthroses in rats by radiographical, biomechanical, mechanical and histological examinations.
The conventional concept of the osteogenetic activity of bone transplants is discussed.
The authors feel that this method will find its clinical application in the operative treatment of pseudarthroses and, in selected cases, of fractures that are known for their tendency to unite slowly.
