This is a case illustrating a 4.5 cm femur lengthening for congenital LLD. The Precice internal lengthening nail was used and the recovery was fast with normal unassisted walking at 4 months.

The patient is a 25 year old male with congenital LLD of 4.5 cm and without deformity. No previous treatment was rendered. The patient and the family were not interested in limb lengthening using external fixation at earlier points in his life.
