A complete hemimelia birth defect refers to what condition?

A complete hemimelia birth defect specifically refers to the absence of an entire limb, either the upper or lower extremity. This condition typically results from a developmental issue during gestation where the limb fails to form completely. In the context of hemimelia, the term "complete" indicates that the entire limb is missing rather than just a part of it.

The distinction of complete hemimelia is significant because it implies that there is no remnant of the limb that would otherwise be present, which is critical information for assessment, treatment planning, and rehabilitation for the affected individual. Treatments may involve prosthetic options or other interventions to help the individual adapt to their condition and improve functionality.

Other terms, such as "missing part of the limb" or "missing midshaft of bony segment," relate to more partial conditions that don't encompass the complete absence of a limb. Therefore, these options do not accurately define what is meant by complete hemimelia. Additionally, "non-functional limb" typically refers to a limb that might be present but does not serve a functional purpose, which is also not synonymous with complete hemimelia.
