Endoskeletal Prosthesis
Pronunciation: en-doh-SKEL-uh-tul
A prosthetic limb design featuring an internal structural frame (pylon) covered by a soft cosmetic foam and skin-tone cover, also called a modular prosthesis.
Full Definition
An endoskeletal prosthesis consists of an internal load-bearing frame—typically a titanium or carbon-fibre pylon—that is covered with a shaped foam cosmesis and a thermoplastic or silicone outer cover. The modular nature of this design allows components such as feet, knees, and adapters to be interchanged without rebuilding the entire device. Endoskeletal construction is the dominant design in contemporary clinical prosthetics. Editors frequently encounter this term in fitting reports, insurance preauthorisation letters, and functional outcome assessments. The term is always written as one unhyphenated word.
Usage
Usage note: One word, no hyphen. Modular is an acceptable synonym in lay-facing documents but endoskeletal is preferred in clinical and billing contexts.
