Meet Larry Sonnenburg

Meet Larry Sonnenburg — and see what’s possible with the POA XOS System.

Developed by Stan Patterson, CP of Prosthetic & Orthotic Associates and co-owner of Southern California Prosthetics, this patented carbon fiber orthotic innovation is changing lives for partial foot amputees and patients living with foot drop, cerebral palsy, paralysis, and other mobility challenges.

Unlike traditional bracing, the XOS features a custom carbon fiber strut fabricated directly into the sole of the patient’s own shoe — providing energy return, enhanced stability, and a more natural stride.

For Larry, the impact has been truly life-changing. Watch him walk.

This is why we do what we do.
