Evolution in Casting Techniques: A Narrative Review of Casting Methods, Techniques, and Innovation.

ABSTRACT

Orthopedic casting has seen a remarkable evolution from ancient practices to cutting-edge innovations. Beginning with ancient Egyptian methods employing bark, linen, and bandages, casting techniques have progressed through historical milestones, including the adoption of plaster of Paris in the 19th century and the introduction of synthetic materials like fiberglass and thermoplastics in the 20th century. Historical progressions transitioned from primitive materials to more sophisticated techniques, such as resin-soaked bandages and starch-based casts. While thermoplastics showcased benefits like adjustability and comfort, widespread adoption faced hurdles due to cost and water resistance limitations. The emergence of 3D printing introduced patient-specific casts with improved ventilation but faced challenges in accessibility, cost, and immediate immobilization. FlexiOH presents as a groundbreaking foam cast by Orthoheal, offering customizable fit, lightweight design, improved ventilation, and moisture resistance. Its potential to reduce ER visits, enhance patient comfort, and streamline application procedures positions it as a promising technology for the future. This paper discusses each casting generation's advantages and drawbacks, highlighting the potential of innovative technologies like FlexiOH to revolutionize orthopedic casting practices, promising improved outcomes, reduced costs, and enhanced efficiency.
