Guidelines in Fracture Management—Nonunion of Long Bones II is the second of a set of two volumes in this series which are dedicated to explaining this kind of fracture. Nonunion of long bones is a very challenging orthopaedic problem, especially the infected nonunion. Further, India, with its huge population and high rate of road traffic accidents, presents an increased challenge due to the remarkably high incidence of such cases. While the previous volume dealt with general principles, techniques and topics, this volume primarily explains the diagnosis and treatment modalities of specific types of nonunion cases and has a more focused coverage.
