Comprehensive Evaluation and Analysis of Multi-Rod Constructs in Adult Spinal Deformity

Abstract

AbstractAdult Spinal Deformity (ASD) is a degenerative condition of the spinal column that is categorized by sagittal imbalance, iatrogenic spinal deformity, and abnormal spinal curvature and leads to diminished quality of life. ASD is frequently repaired via neurological or orthopedic spine surgery to restore normal curvature and alignment. Surgical correction often involves the use of single, dual, or multiple-rod constructs. Multirod constructs, in particular, offer improved stability and deformity adjustment that is unmatched by single and multi-rod assemblies, but may include significant disadvantages. This review seeks to weigh the costs and benefits associated with the use of multiple rods in adult spinal deformity surgery.
