Persistent Medial Subluxation of the Ulna with Radiotrochlear Articulation

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