Limb Deformities

Help for Kids With Differently Shaped Limbs

“Limb” is another name for the arms or legs. Kids with limb deformities have differences in the way their arms or legs are shaped. For example, their legs may be curved or one might be shorter than the other. Or, a bone in the arm may be short or missing. At Nemours, our pediatric orthopedic surgeons are experts at diagnosing and treating bone length differences and limb deformities. We’ll recommend the best treatment for your child and help you understand what to expect every step of the way.

Conditions We Treat

Conditions We Treat


Some children are born with a limb deformity and others develop it when they’re older. A limb length discrepancy is when one arm or leg is longer than the other. A small difference in length might not be noticeable at all. A bigger difference, especially in a leg, can cause problems such as a limp, pain or early arthritis. Some common types of limb problems include:

  • Blount disease (a growth disorder that affects the shin bone)
  • bowlegs (when the knees bow out)
  • congenital short femur (when a child is born with a short femur — the bone between the hip and knee)
  • fibular hemimelia (when there’s a missing part of the fibula — the outer bone between the knee and ankle)
  • hemihyperplasia (when one side of the body is larger than the other)
  • infection that damages growth plates (the areas of active, new bone growth near the ends of bones)
  • knock knees (when the knees bend in)
  • neurofibromatosis (a condition that causes tumors to grow on the nerves)
  • trauma (bone fractures)
Services We Offer

Services We Offer


To diagnose and treat limb length problems, we use a team approach that combines the expertise of our pediatric orthopedic surgeons, radiologists, physical and occupational therapists, and orthotists (who fit braces or splints). We also work with specialists from genetics, physical medicine and rehabilitation (PM&R) and Child Life to provide a range of services — all under one roof.

Our limb deformities treatment and support services may vary depending on the location and your child’s condition. But we offer both surgical limb reconstruction and nonsurgical treatments such as:

  • epiphysiodesis (surgery to slow the growth of the longer leg)
  • exercise programs tailored to kids’ specific needs
  • limb lengthening, shortening and correction
  • shoe lifts and bracing
