Abstract
The elbow joint is contained within a capsule the medial and lateral thickenings of which comprise the radial and ulnar collateral ligaments; ligamentous injury may occur with or without injury to the adjacent flexor or extensor tendons. The ulnar collateral ligament (UCL) provides both static and dynamic stability to the elbow acting as the primary medial stabilizer in flexion. The anterior band of the UCL is the primary stabilizer of the elbow against valgus stress. In this chapter, the normal magnetic resonance imaging (MRI) anatomy of the UCL is discussed as are the most common injuries to the anterior and posterior bands of the UCL. MRI images of normal anatomy, ligamentous injuries to the professional pitching athlete and injuries to the amateur competitor, to include Little Leaguer’s elbow, are shown.
