Affordable Multi-Axial Adjustable Socket for Immediate Post-Operative Prosthesis: Enhancing Early Rehabilitation in Developing Countries

Transfemoral amputation, the surgical removal of the leg above the knee, is performed when the limb is severely damaged due to trauma, infection, or tumours. Limb loss is a life-altering event, impacting both physical mobility and psychological well-being. A well-fitting prosthetic socket is crucial for successful rehabilitation. However, by the time patients seek prosthetic care, typically 2–3 years post-amputation, their residual limb undergoes significant changes, including contractures, edema, uneven muscle atrophy, and phantom limb sensations. These changes contribute to a poor socket fit, prolonged gait training, and increased rehabilitation time. Immediate postoperative prostheses (IPOP) can mitigate these issues by providing early weight-bearing and mobility. However, their limited use is attributed to frequent socket modifications due to residual limb volume fluctuations, high costs, and fabrication challenges. To address these limitations, we propose a novel prosthetic socket design that accommodates volume changes, allowing for continuous use throughout the recovery phase. This innovation aims to enhance early rehabilitation, reduce costs, and improve patient confidence in ambulation.
