What Is Limb Lengthening?

Limb lengthening is an advanced orthopedic procedure used to correct limb length discrepancies, deformities, and certain congenital or post-traumatic conditions. At Mount Sinai, our limb lengthening specialists use innovative surgical and non-surgical techniques to improve alignment, restore function, relieve pain, and help patients achieve their mobility goals through personalized treatment plans.
