Orthotics
T
he integrated KAFO system was designed to give the orthotist maximum prescriptionfilling capability from a minimum inventory of interconnecting modular components.
KAFO is a completely modular system for lower extremity orthoses. The Drop Lock Knee
Joints are made of the highest quality stainless steel. With the Drop Lock Ring raised and
the joint flexed, there are no sharp angles nor jutting extension stops to snag or cut clothing.
The Hosmer Ankle Joints, carefully engineered for maximum strength and durability, are
available as Dorsiflexion Assist, Free/Limited Motion, and Double Action with or without
pins. The Side Bars are secured into channels for a stronger joint construction and to help
prevent breakage when being bent. There are three stirrup systems; the Standard Shoe,
the molded UCBL Shoe Insert and the Caliper. All stirrups are made of heat treated stainless
steel.

KAFO System
KAFO System
• KAFO (Knee Ankle Foot Orthosis) modular components provide maximum flexibility
• Components are easily assembled into a custom orthosis
• Provides both light and heavy duty side bars, knee joints, stirrups, and ankle joints
To Order: Each long leg orthosis requires two knee joints, four side bars, and two ankle joints with matching stirrups
to make a complete system. Each short leg orthosis (AFO) requires two straight side bars, and two ankle joints with
matching stirrups. Usual selection of knee and ankle joints is straight for the lateral side and contoured for the
medial side. See following pages for ordering information.
