Guichet Nail Patients

Lengthening - Ratcheting

The nail is made of two sliding tubes. After transverse osteotomy of the bone and fixation of the nail in each bone extremity, alternate rotation of one tube with respect to the other authorizes lengthening of the system through repeated go-and-forth rotations.

Guichet Nail Patients

Full Weight Bearing

The nail is made of the toughest material available for medical use allowing a controlled full weight-bearing from the day of surgery (Post Operative Day 0).

Guichet Nail Patients

Excercising on a static bike

Gentle sports like bike are allowed according to surgeon's recommendations after patient’s evaluation.
