BACKGROUND: In 1962, Bertil Stener first described the anatomy and treatment of the displaced ulnar collateral ligament of the metacarpophalangeal joint, later called the Stener lesion. Since Stener's publication, treatment algorithms for ulnar collateral ligament rupture have aided in preoperative diagnosis, yet the best diagnostic method to assess ligament displacement remains largely undefined.METHODS: An extensive literature search was performed to explore the treatment evolution of the Stener lesion and explore how technical development has influenced Stener lesion diagnosis. We also sought to illuminate the life and work of Bertil Stener.RESULTS: Studies evaluating the use of magnetic resonance imaging (MRI) and ultrasound (US) technology have suggested that these modalities have improved Stener lesion diagnosis.CONCLUSION: Despite the utility of developing MRI and US technology, consensus for one superior diagnostic tool for Stener lesions does not currently exist.
