Please login to see pricing and build a purchase order.

The PDE™ Orthopaedic spring system is a modular AFO spring for composite brace designs. This simple ‘plug and play’ system provides the ability to adjust alignment at both the footplate and upper cuff after the brace has been fabricated. Clinicians can properly tune brace dynamics and adjust rotation, plantar & dorsiflexion alignment. Easily change spring stiffness to meet changing patient needs. Designed for everyday use in situations where pain and offloading of weight may be key factors.

*Note: Additional hardware is needed for brace fabrication & assembly. Visit supplier website or download the product infosheet (pdf) for details and compatibility.
