Dr. John Herzenberg, Director of the International Center for Limb Lengthening, describes how the Precice™ internal lengthening nail works and how it benefits children and adults with limb length discrepancies and limb deformities. International Center for Limb Lengthening patients report that the Precice™ nail lengthening was less painful than external lengthening and that it made their lives easier. Doctors found patients have less scarring and better results with internal lengthening. A patient shares his positive experience with internal limb lengthening to address stunted growth in one leg due to a growth plate fracture in his youth.
