Persistent Medial Subluxation of the Ulna with Radiotrochlear Articulation

Abstract

Two patients-one with a terrible triad fracture dislocation and one with an anterior olecranon fracture dislocation—were<br />treated for maltracking of the elbow (medial subluxation). The radial head articulated with the lateral trochlea while the<br />ulnar trochlear notch was perched over the medial trochlea. The late revision surgery could not correct the subluxation<br />because the joints were accustomed to the new alignment, however the overall function was reasonable.
