The field of interventional orthopedics is changing the landscape of orthopedic care as patients seek less invasive options for the treatment of common conditions like arthritis, rotator cuff tears, and degenerative disc disease. Offering easy-to-follow, step-by-step guidance on both peripheral joint and spinal procedures, Atlas of Interventional Orthopedics Procedures is the first reference to provide this practical content in one authoritative, user-friendly text. Abundantly illustrated and easy to read, it presents simple to advanced injection skills covering all orthopedic and physical medicine procedures using up-to-date imaging techniques.

The plant fossil record provides evidence that the genus Metasequoia was widely distributed and experienced a wide range of climatic and environmental conditions throughout the Northern Hemisphere from the early Late Cretaceous to the Plio-Pleistocene. Today the genus is limited to one species with approximately 5,000 mature individuals growing in the Xiahoe Valley in southeastern China. This book is a distillation of the collective efforts and results of the world’s Metasequoia specialists and enthusiasts. It is the most up-to-date and comprehensive reference source for the genus and the authors have sought to incorporate obscure, hard-to-get and non-English reference sources. The book reviews what is known about the biology, ecology and physiology of fossil and living Metasequoia, current research directions and problems that remain unresolved.This book presents a definitive overview of fossil and living Metasequoia and was written by sixteen of the world’s experts on this important genus. Given the reality of increasing human pressure and the inevitability of global change, efforts to conserve this ancient genus are underway.
