This animation demonstration of a revolutionary surgical hardware system and technique developed by Dr. Dennis Crandall of the Sonoran Spine Center in Phoenix, Arizona, USA.

This technique is identified by Campbell's Operative Orthopaedics as the "Crandall Method" for treating scoliosis, kyphosis, and spondylolisthesis.

Campbell's is a widely used resource for orthopedic surgery and "...an essential resource for the operative orthopedic surgeon." (— JAMA)
