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. The new Guichet Nail® Version 2 brought outstanding advancements like sports during lengthening with a strong mechanical resistance.
The new Guichet Nail® Series 21 is based on the Version 2. Stronger material, multiple sizes (20 cm with a gain of 8 cm for very short femurs, etc.) and custom made implants for specific conditions are now available.
Implants provide a precise and accurate gain (1/15th of a mm) fully controllable with no shortening risk. The Guichet Nail® is a fully mechanical, biocompatible and reliable system.

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.
