Semi-flexible sockets for amputation below the knee

Area of Science:

• Prosthetics and Orthotics
• Biomedical Engineering
• Rehabilitation Medicine

Background:

• Below-knee amputees often face challenges with prosthetic socket comfort and skin integrity.
• Existing prosthetic assessment methods may not fully capture functional limitations related to socket fit.
• Active amputees require advanced prosthetic solutions to maintain optimal function and quality of life.

Purpose of the Study:

• To evaluate the efficacy of a semi-flexible socket in a cohort of below-knee amputees.
• To identify challenges in assessing prosthetic components and establish appropriate methodologies.
• To determine the suitability of semi-flexible sockets for active amputees with specific functional concerns.

Main Methods:

• A cohort of 47 consecutive below-knee amputees was fitted with a semi-flexible socket.
• Prosthetic component assessment and methodological appropriateness were critically examined.
• Patient function was monitored, with particular attention to comfort, perspiration, and skin condition.

Main Results:

• The semi-flexible socket demonstrated potential benefits for amputee patients.
• Difficulties were encountered in the assessment of prosthetic components and methodology.
• Preliminary findings indicate the socket's promise in addressing comfort and skin issues.

Conclusions:

• The semi-flexible socket warrants broader application and further investigation in clinical practice.
• Active amputees experiencing functional impairments due to socket-related issues may benefit from this technology.
• Continued research is essential to optimize the use of semi-flexible sockets in prosthetic rehabilitation.
