A novel transtibial casting system utilizes polystyrene beads and dilatancy principles for rapid, one-hour prosthesis fabrication. This plaster-less, portable system offers cost-effectiveness and environmental benefits for prosthetic care.

Area of Science:

  • Biomedical Engineering
  • Prosthetics and Orthotics
  • Materials Science

Background:

  • Traditional transtibial prosthesis fabrication is time-consuming and resource-intensive.
  • Existing casting systems, like the CIR Sand Casting System, rely on principles such as dilatancy.
  • There is a need for more efficient, portable, and environmentally friendly methods for prosthetic socket fabrication.

Purpose of the Study:

  • To introduce a new, lightweight casting system for transtibial socket fabrication.
  • To leverage the dilatancy principle using polystyrene beads for improved casting efficiency.
  • To reduce fabrication time, cost, and environmental impact in prosthetic device creation.

Main Methods:

  • Development of the CIR Casting System employing polystyrene beads instead of silica sand.
