A leg extension prosthesis is a custom prosthetic limb extension designed to lengthen a shortened leg caused by congenital limb differences, limb loss, or leg length discrepancy (LLD). Unlike a full artificial leg, this prosthetic leg extension supports and stabilizes the existing limb to restore equal leg length, balance, and a natural walking gait. Built for weight-bearing and mobility, leg extension prostheses use advanced materials such as carbon fiber, lightweight aluminum, and medical-grade liners to enhance comfort, durability, and independence. Benefits of a Leg Extension Prosthesis Corrects limb length discrepancy Improves balance, posture, and gait symmetry Reduces fatigue and joint strain Enhances mobility and walking efficiency Supports daily activities, work, and recreation Improves overall quality of life Who Uses a Leg Extension Prosthesis? Individuals with congenital limb deficiencies Such as fibular hemimelia, proximal femoral focal deficiency (PFFD), or other conditions resulting in a shortened limb. People with leg length discrepancy Post-trauma or post-surgical patients Whose limb shortening resulted from injury, infection, or bone disease Children and adolescents needing adjustable prosthetic solutions
