Elbow hemiarthroplasty is not the "half" of elbow arthroplasty.

Where this comes from

Abstract

Distal humeral arthroplasty (DHA), also termed elbow hemiarthroplasty, replaces the distal humeral articular surface while preserving the native ulnar and radial articular surfaces. Compared with total elbow arthroplasty (TEA), DHA has distinct characteristics, resulting in different surgical indications and clinical outcomes. The prefix "hemi-" may be misleading, as DHA should not be regarded as half--the humeral part of TEA.
