Multirod Constructs in Spine Surgery.

➢ The use of multirod constructs (≥3 rods) in complex spine surgery has increased as its utility has been recognized over the past decade.➢ There are multiple different rod configurations that may be utilized on the basis of the desired supplemental rod function, with each type having its own advantages and clinical indications.➢ Literature has continued to demonstrate a reduced incidence of pseudarthrosis, rod fracture, and reoperation when comparing multirod constructs with traditional dual-rod constructs.➢ The use of consistent nomenclature when describing multirod constructs will allow for more productive clinical and biomechanical research.
