The patterns of laxity of normal wrists subjected to dorsal and volar stresses were analysed. Dorsal and volar displacement tests were carried out on both wrists of 50 subjects under image-intensifier control. Lateral projections in neutral, and dorsal and volar stress positions were taken to analyse the behaviour of the carpal bones. Varying degrees of capitolunate subluxation under dorsal and volar stress were noted. Dorsal displacement of the capitate appeared to be more prominent than volar displacement. The lunate either extended or subluxed dorsally in response to a dorsal stress, suggesting a different pattern of laxity for the radiolunate joint. These observations provide a baseline for the interpretation of dorsal and volar stress views in the symptomatic wrist.
