Non-syndromic Hemimelia: A Parent's Guide to Congenital Limb Differences

At a Glance

Non-syndromic hemimelia (longitudinal limb deficiency) is an isolated congenital condition where a child is born with a shortened or missing bone in the arm or leg, but is otherwise completely healthy. Care focuses on limb reconstruction or adaptation to maximize long-term function.

Hearing that your child has been diagnosed with a limb difference can be frightening and overwhelming. This guide is designed to empower you with evidence-based information, helping you understand the diagnosis and prepare for the road ahead.

Non-syndromic hemimelia—now more commonly called a longitudinal limb deficiency—is a rare congenital condition where a specific bone in the arm or leg is shorter than usual or missing, but the child is otherwise completely healthy [1].

This resource will help you navigate the medical terminology, understand your child’s specific diagnosis, and evaluate your treatment options. We encourage you to read through the sections at your own pace:

02

Types and Classifications of Longitudinal Limb Differences

Learn about types of longitudinal limb differences (hemimelia) in children, including fibular, tibial, radial, and ulnar dysplasia classification systems.

03

Treatment Strategies for Lower Limb Differences

Learn about treatment options for fibular and tibial hemimelia, including the SUPERankle procedure, limb reconstruction, and amputation with prosthetics.

04

Restoring Function: Upper Limb Treatment Strategies

Learn about upper limb treatment for hemimelia, including radial and ulnar deficiencies. Understand pollicization, centralization, and therapy options.

05

Building Your Multidisciplinary Care Team

Learn how to build a multidisciplinary care team for your child's congenital limb difference. Discover which specialists to include and questions to ask.

06

The Decades Ahead: Long-Term Outlook and Support

Learn about the long-term outlook for longitudinal limb deficiency (hemimelia). Understand physical wear-and-tear, psychosocial support, and prosthetic choices.

Common questions in this guide

What is non-syndromic hemimelia?
Non-syndromic hemimelia, also called longitudinal limb deficiency, is a congenital condition where a specific bone in a child's arm or leg is shorter than usual or missing entirely. Because it is 'non-syndromic,' the child is otherwise completely healthy without other underlying medical conditions.
What are the different types of hemimelia?
Doctors categorize these limb differences based on the specific bone that is missing or shortened. The most common classifications are fibular and tibial differences in the lower limbs, and radial and ulnar differences in the upper limbs.
What are the treatment options for lower limb differences?
For leg differences, families typically work with specialists to navigate two main strategies: limb reconstruction surgeries to lengthen and straighten the affected bone, or amputation followed by the use of a custom prosthesis.
Will my child have other health issues because of this limb difference?
Because this diagnosis is classified as non-syndromic, the limb difference is an isolated event. However, your child's pediatrician and care team will perform comprehensive initial evaluations to confirm that no other conditions or syndromes are present.
