Transhumeral Amputation
Pronunciation: trans-HYOO-mer-ul
Amputation of the upper limb through the shaft of the humerus, resulting in a residual segment above the elbow joint.
Full Definition
Transhumeral amputation, also referred to as above-elbow amputation, involves surgical removal of the upper limb at a level through the humeral diaphysis, preserving varying lengths of residual bone. The length of the residual humerus significantly influences prosthetic fitting, harnessing options, and functional outcomes. Editorial use of 'transhumeral' rather than 'above-elbow' is preferred in contemporary clinical and prosthetic documentation. Editors should ensure consistent use of the term and verify that it is not conflated with 'transradial' (below-elbow) amputation levels. It appears frequently in prosthetic prescription forms, functional assessment reports, and insurance pre-authorization letters.
Usage
Usage note: Prefer 'transhumeral' over the colloquial 'above-elbow' in all formal clinical and billing documents. Verify amputation level before selecting L-codes.
