The Effect of Differing Spinal Fusion Instrumentation on the Occurrence of Postoperative Crankshaft Phenomenon in Adolescent Idiopathic Scoliosis

These findings suggest that in skeletally immature patients with AIS, hybrid instrumentation cannot effectively prevent occurrence of the crankshaft phenomenon, whereas interval and consecutive pedicle screw instrumentation may be more (and equally) efficacious in this regard.
