DF2® — Functional Femoral Brace

DF2® (Dynamic Femur Fracture Brace) is a functional brace developed by OrthoPediatrics specifically for the treatment of pediatric femoral shaft fractures. It is designed as an alternative to the pelvic-pedal (spica) cast, immobilizing the femur, knee, and hip through preconfigured, physician-adjustable components.

In a prospective randomized study presented at the 2022 POSNA meeting (Children’s Hospital Los Angeles), functional bracing produced outcomes equivalent to the spica cast in children with femoral shaft fractures, with no cases of malunion in either group. Unlike spica cast application, the brace can be fitted at the patient’s bedside, without general anesthesia and without operating-room time.

The functional design allows access for skin care and dressing changes, reduces exposure to cast-related procedures, and eases the family’s routine — including the use of a standard car seat. The brace is typically worn for approximately 4–6 weeks, with the duration determined by the treating physician according to the progress of fracture healing.

• Fixation of femoral shaft fractures in pediatric patients aged approximately 6 months to 5 years.
• Alternative to the pelvic-pedal (spica) cast.
• Immobilization of the femur, knee, and hip throughout fracture healing.
