    AbstractNail changes similar to those reported by Terry and Lindsay were defined in an elderly inpatient population. Two hundred fifty-eight patients were studied, and an overall incidence of 19 per cent was found. There was no significant difference between men and women. The only significant correlations in this study were with osteoporosis and thin skin. Eight men with nail changes were compared with seven men without such changes by calculating the metacarpal index of cortical bone mass. The index was much lower in patients with nail changes (t = 2.64; P less than 0.01). All patients with nail changes had thin skin. No correlations were found with serum albumin, liver function, or kidney function. These nail changes are less frequent in the "less frail" elderly living in the community. Changes of the Terry type are common in children but disappear by early adult life. It is suggested that the nail changes are age-related phenomena and that they may reflect an underlying disturbance of collagen being manifested as changes in the nail bed, skin, and bone.
