The incidence of Kienböck disease after a single wrist traumatic incident is rare but has been reported by several authors. Although most evidence consists of case reports and case series, two possible concerns have been suggested. First, a traumatic alteration of the wrist anatomy and measurements increase stresses on the lunate. These changes mostly follow fractures around the wrist and can be regarded as acquired risk factors that contribute to the development of Kienböck disease. Second, some wrist injuries may tear ligaments around the lunate and damage the accompanied blood vessels; so, compromising the circulation to the lunate. Surgeons should be aware of the development of Kienböck disease following a single wrist trauma to enable early diagnosis and management to improve outcomes.
