The Bone Collection is a comprehensive discussion on one of the most important issues we face: Injury to bone. I cover in detail the various classifications of fracture and how to recognize them. In addition the osteochondroses at different sites are covered, as is a discussion on the general principles of bone health, including remodelling in response to stress, and the environmental, endocrine and metabolic parameters that may affect bone. This leads us into an in depth discussion of stress fracture, with particular reference to tibial stress fracture and tibial stress reaction. In all, I present to you over 40 pages of the most up-to-date information on bone health and injury available. It represents over 6 hours of CME credits and so is an incredibly valuable resource.
