Once unpredictable, internal lengthening nails have evolved into sophisticated magnetically actuated implants that can distract or compress long bones with optimal force and high precision. These devices have fundamentally changed the field of limb lengthening and complex limb reconstruction making the entire patient experience simpler and less painful. This chapter will analyze the biomechanical performance of the magnetic internal lengthening nail, using clinical cases to demonstrate many of the techniques employed to ensure good results.
