This book focuses on the internal fixation of long bones by using intramedullary locked nails in a closed technique. Intramedullary fixation fulfils the biological requirements for fracture healing and minimises surgical trauma. The text illustrates the use and relevance of this technique in orthopaedic and trauma surgery including reconstructive surgery, covering the basic scientific principles of reaming and locking as well as basic and advanced surgical techniques. Prevention of complications and complication management are also discussed in detail, making it an ideal text for those with an interest in the proper use the techniques described.
