Flex-Foot® Junior

Product Overview

The Össur Flex-Foot® Junior is a carbon fiber prosthetic foot engineered for children who require additional energy return during walking, running, and play activities. This pediatric-specific design supports varied movement patterns from classroom walking to playground activities.

Designed for pediatric users weighing 15–45kg (33–99 lbs), the Flex-Foot® Junior features a full-length toe lever that matches the natural foot length, promoting symmetrical gait patterns and balanced stride mechanics. The integrated male pyramid adapter and low-profile design minimize build height while the sandal toe configuration allows for standard footwear options. This versatile prosthetic foot serves children with transtibial, transfemoral, knee disarticulation, or hip disarticulation who maintain moderate to high activity levels.

Features and Benefits

• Full-length toe lever: Anatomically proportioned keel extends to match sound-side foot length, facilitating balanced push-off and reducing gait asymmetries.
• 15–45kg weight range: Accommodates growing children from 33 to 99 pounds with consistent performance characteristics across the entire weight spectrum.
• Integrated male pyramid: Built-in adapter simplifies alignment procedures and reduces overall build height for better cosmetic appearance.
• Proportional response design: Carbon fiber layering technique optimizes energy storage and return from mid-stance through toe-off based on user weight.
• Sandal toe configuration: Narrow, anatomically shaped forefoot allows use with open-toe footwear and provides natural toe break location.
• Weatherproof construction: Resists fresh water exposure and humid environments, though not intended for full submersion.
• Progressive stiffness profile: Pyramid adapter shape contributes to graduated stiffness that supports smooth rollover through stance phase.
• Low-profile architecture: Minimized structural height preserves leg length symmetry and reduces compensatory hip movements.
• L5981 reimbursement code: Established billing code simplifies insurance authorization and reimbursement processes.

The Flex-Foot® Junior delivers consistent energy return for children who need enhanced propulsion during gait, supporting natural development through school activities, sports participation, and active play with peers.
