%X A Stener lesion is a displaced tear of the ulnar collateral ligament in the metacarpophalangeal joint of the thumb in which the adductor pollicis aponeurosis is positioned between the retracted ligament and the injury site, preventing natural healing. This lesion was first described in 1962, and since then, both radiologists and orthopedists have considered it important to treat surgically. Although this lesion was originally described in the thumb, this injury mechanism can occur in other joints of the hand, knee, and foot. The purpose of this study was to review the relevant aspects of classic Stener lesions of the thumb, as well as other Stener-like lesions, including their anatomy, mechanisms of lesion formation and imaging features. The Stener-like injury pattern often necessitates surgical repair or reconstruction; thus, it is essential that radiologists recognize and report the different patterns of injury.
