Dynamic positioning of scoliotic patients during spine instrumentation surgery.

Study Design: Evaluation of a novel Dynamic Positioning Frame (DPF) for scoliosis surgery to improve presurgical correction.

Objective: To assess a DPF for scoliosis surgery and demonstrate how its design offers additional presurgical correction of the 3-dimensional deformity.

Summary Of Background Data: Patient positioning is an important step in scoliosis surgery.
