Ulnar variance and its relationship to ligament injuries of the wrist

An anatomic study on cadavers and a clinico-radiological study on patients were undertaken to verify if ligament injuries of the wrist could be associated with ulnar variance. Neither scapholunate nor triquetrolunate ligament injuries could be related to shorter or longer ulnae. Longer ulnae were associated with significantly more perforations of the triangular fibrocartilage complex (TFCC).
