Our specialists take a multidisciplinary team approach to diagnose and correct limb inequalities using advanced, nonsurgical treatments (such as physical medicine and rehabilitation) and state-of-the-art, minimally invasive limb lengthening surgical procedures and limb reconstruction. Recognized as international leaders and pioneers in pediatric orthopedics and orthopedic surgery, our specialists and care teams are dedicated to treating your whole child — and family — not just the condition.

Read More About Limb Lengthening and Reconstruction at Nemours

Limb length discrepancy in children results from congenital malformations (defects present at birth), acquired problems (such as trauma) and certain diseases (neurofibromatosis, Blount disease). At Nemours, we understand the complex conditions and injuries that can cause functional discrepancy, and will work with you to understand available treatment options specific to your child’s needs.

Conditions We Treat at Nemours

Some of the conditions that require limb lengthening or limb reconstruction include:

  • bowlegs (genu varum, Blount disease) and knock knees (genu valgum)
  • growth plate injuries
  • congenital (present at birth) limb deformities (fibula hemimelia, congenital short femur, radial clubhand, etc.)
  • upper extremity deformity (Madelung disease, cubitus varus, multiple hereditary exostoses)
  • short stature (skeletal dysplasias, growth hormone patients)
  • fracture malunions or nonunions 

When you come to Nemours, you can expect compassionate care in a family-centered environment. This means that every detail, from our medical care and support services to our facilities and amenities, were designed with you in mind. We value your opinion and encourage participation in your child’s care, because you know your child best.

    • Hemihypertrophy: overgrowth of one side of the body
  • Acquired problems (developed later in life), such as:
    • Trauma: bone fractures
    • Infection that damages growth plates: resulting in severe limb shortening or deformities
