About us

X-os was created in 2007 to provide innovative, efficient and secure solutions in the orthopaedic field of Limb Lengthening and Reconstruction with internal devices.

The first product, the Guichet Nail® V1, was the evolution of the Albizzia® System developed in 1986, first ever full weight bearing nail (under special circumstances only like walking on flat floor).

The new Guichet Nail® Version 2 brought outstanding advancements like soft sports (Elliptical, resistance bike, when indicated by your surgeon according to your medical condition) during lengthening with a strong mechanical resistance. In 2023, we released the 3D version.

The current Guichet Nail® Version 2 uses strong material, multiple sizes (16 cm with a gain of 9 cm for very short femurs, etc.) and custom-made implants for specific conditions are now available.

A complete set of instrumentation has been developed with:

> A precise distal targeting system for minimising exposure to X-rays during surgery

> An intramedullary saws optimising the healing response

Implants are carefully designed and tested from biology to clinical studies for:

> Full Biocompatibility, reliability and safety, insuring to patients a fast recovery

> Easiness of use for the surgeon

The quality and security of our products and techniques are our primary objective.
