.
Essentials of Spinal Cord Injury is written for the spinal cord injury (SCI) team and reflects E Michael G. Fehlings
the multidisciplinary nature of treating patients with SCI. It integrates emerging medical s
s
and surgical approaches to SCI with neuroanatomy, neurophysiology, neuroimaging, e Alexander R. Vaccaro
neuroplasticity, and cellular transplantation. This comprehensive yet concise reference n
will enable neurosurgeons, orthopedic surgeons, neurologists, and allied health professionals t Maxwell Boakye
i
caring for SCI patients to translate research results into patient care. It is also an excellent a
Serge Rossignol
resource for those preparing for the board exam in SCI medicine. ls

Key Features: o John F. Ditunno, Jr.
f
• Material is cross-referenced to highlight relationships between the different areas of SCI

S Anthony S. Burns
• Chapters are concise, focused, and include key points, pearls, and pitfalls
p
• An Overview of the Literature table is provided in most chapters, giving readers a meaningful
i
distillation of each publication referenced n
• Each editor is a world-renowned expert in one of these core disciplines involved in the a
l
management of SCI patients: neurosurgery, orthopedic surgery, spinal cord science, and
C
rehabilitative medicine
o
This is a must-have guide that all neurosurgeons, orthopedic surgeons, neurologists, and allied r
d
health professionals involved in the care of SCI patients should have on their bookshelf—they

will repeatedly refer to it in the course of their practice. I

I would like to dedicate this book to my family, colleagues, students, and patients.
Michael G. Fehlings
My greatest thanks go to all my patients whom I have met throughout the years with spinal
cord injury who have educated me during their journey through treatment and rehabilitation.
Alexander R. Vaccaro
To my wife, Petrina, for her love, kindness, patience, understanding, and support, and without
whom this would not have been possible. To my children, Kwame and Amie, for being fun and
making this worthwhile. To my parents for all their sacrifices for me: my late father Kwaku for
being the greatest dad and my hero, and my mother, Alice, for being the greatest mom with her
encouragement and enduring support.
Maxwell Boakye
To my students and colleagues who have constantly renewed my interest in spinal cord re-
search and to my family who endorsed the crazy schedule needed for this work. I acknowledge
also the funding organizations, such as the Canadian Institute for Health Research (CIHR), that
have unfailingly supported my research throughout these years.
Serge Rossignol
It has been and continues to be a privilege to work in such an amazing and stimulating field.
We admire the many individuals whose care we have had the opportunity to participate in and
are thankful to the many colleagues, teachers, and mentors whom we have had the opportu-
nity to work with over the years.
Anthony S. Burns and John F. Ditunno Jr.
