History

The Slocum Research and Education Foundation’s original works were spearheaded by Drs. Slocum, James, and Collis who, along with their many collaborators, produced seminal works in the field.

In 1962, Dr. Donald Slocum and Bill Bowerman partnered to publish an article in the journal of Clinical Orthopedics titled "Biomechanics of Running". Bill Bowerman, the University of Oregon Track & Field head coach, future US Olympic head coach, and co-founder of Nike, proposed that making running shoes lighter would aid in preventing athletic injuries. With the help of Drs. Donald Slocum and Stanley James the trio embarked on the mission to treat and prevent running injuries by redesigning athletic footwear. As Dr. James recollects, “Nike has been running ever since.”

Following his partnership with Bowerman, Dr. James continued to research biomechanics and athletic injuries. In a collaboration with the University of Oregon’s Department of Human Physiology, he authored over 57 publications. His work includes pioneering articles such as "Injuries to Runners" which was published in one of the first editions of the American Journal of Sports Medicine in 1976.

As a member of the first AOSSM research committee, Dr. James helped define the critical knowledge gaps within the field of Sports Medicine. In 2012, Dr. Stanley James was presented with the Distinguished Alumnus Award for Achievement from the University of Iowa. The award was followed in 2010 by an induction into the University of Oregon’s Track and Field Hall of Fame, and in 2012 Dr. James joined Drs. Slocum and Larson in the American Orthopedic Society for Sports Medicine’s (AOSSM) Hall of Fame.

As the field of Sports Medicine matured and flourished under the leadership of Dr. Slocum and Dr. James, a young surgeon by the name of Dennis Collis joined the practice. Newer surgical modalities were emerging during this time, most notably joint replacement to treat osteoarthritis. In 1971, Dr. Collis performed the first total hip replacement procedure in Eugene, OR. Committed to documenting the reasons for success or failure, Dr. Collis developed one of the first computerized, comprehensive outcomes tracking and monitoring systems in a private practice setting.

Following in the footsteps of his partners and mentors, Dr. Collis’ provided leadership and mentorship on the local, national, and international stages as the President of The Hip Society, Russell Hibbs Society, North Pacific Orthopedic Association, and the Association of Bone and Joint Surgeons. In addition, Dr. Collis was the Chairman of the Board for the national Orthopedic Research & Education Foundation from 1995 to 1998 and served locally on the governing board of Sacred Heart Medical Center for 16 years.

Together this group set the standard for orthopedic clinical investigation and laid the groundwork for the formation of the Slocum Research and Education Foundation.
