The mini-invasive surgery has become in recent years a practical necessity for reducing the risk of infection, the importance of blood loss and volume of implants.At the hip it became necessary to make small incisions requiring the use of appropriate equipment combined with the full knowledge of the local anatomy.Mini-invasive surgery requires the surgeon to perfectly set up the indications for surgery and to know the exact loco-regional anatomy unique to each patient he treats. Methods must be very precise and deserve visual explanations to help teach the young surgeon.In this book, the different surgical approaches to the hip are presented in terms of their anatomical specifications and indications. Films of these different operations were performed by international specialist authors and some of these images are used to explain the surgical technique described in the book.The very didactic and visual presentation based on operative films is very helpful for the understanding of these methods.
