Product title: The Netter Collection of Medical Illustrations: Musculoskeletal System, Volume 6, Part II - Spine and Lower Limb (Netter Green Book Collection)
Product description: "This work is all about Netter's collection of color medical illustrations. With the passage of time and changes in procedures, however, more of these illustrations are expected to become less relevant. The book effectively addresses this problem by using new illustrations that mimic the style of the master. Those of us in academic medicine greatly appreciate the teaching value of these illustrations for their accuracy and clarity of message. This update is an important contribution to all medical science libraries. I strongly recommend it for anatomists, orthopaedists, neurosurgeons, podiatrists, medical illustrators, and trainees in these areas."- Edward Abraham, MD (University of Illinois at Chicago College of Medicine) Doody Review Services
