Computer aided design of prosthetic sockets for below-knee amputees

Area of Science:

• Biomedical Engineering
• Rehabilitation Technology
• Computer-Aided Design (CAD)

Background:

• Traditional prosthetic socket fabrication relies on manual sculpting with tools like rasps and plaster.
• Achieving precise and consistent socket modifications can be challenging and time-consuming with manual methods.

Purpose of the Study:

• To describe a novel computer-aided sculpting system designed for prosthetic applications.
• To present a digital alternative that mirrors traditional sculpting techniques for prosthetic socket modification.

Main Methods:

• The system utilizes a computer, graphics terminal, mouse, and on-screen cursor as digital sculpting tools.
• System software enables systematic modifications to a primitive prosthetic socket.
• Techniques employed are analogous to manual sculpting processes used by prosthetists.

Main Results:

• The computer-aided system provides a digital environment for prosthetic socket refinement.
• It allows for systematic and precise modifications, potentially improving prosthetic fit and function.
• The system integrates digital tools with established prosthetic sculpting principles.

Conclusions:

• Computer-aided sculpting offers a viable and advanced method for prosthetic socket design and modification.
• This technology has the potential to streamline the prosthetics workflow and enhance patient outcomes.
• The system represents a significant step towards integrating digital technology into clinical prosthetics practice.
