Abnormal joint mobility is an important factor in movement dysfunction and physical disability. Because the decision to treat impaired joint mobility in an older individual may be influenced by assumptions concerning normal range of motion (ROM) at older ages, it is important to establish population-based normative values for hip and knee ROM by age, race, and sex. This study used data from the first National Health and Nutrition Examination Survey (NHANES 1), which involved a national probability sample of persons drawn from the civilian noninstitutionalized population of the United States. Goniometric measurements of hip and knee active range of motion (AROM) were obtained from a subset of the sample consisting of 1,892 subjects. This analysis was limited to the 1,313 white and 370 black subjects. Univariate statistics, weighted by the probability of selection into the sample, were calculated for 12 sex-race-age-group–specific categories. These normal AROM values for the hip and knee calculated from this population-based sample were found to differ from estimates found in textbooks by as much as 18 degrees. With one exception, normal values for all motions were lower in the oldest age group than in the youngest age group. The differences in mean AROM were generally small, ranging from 3 to 5 degrees. Only in the case of hip extension did the difference in mean AROM between the youngest and the oldest age groups constitute a decline of more than 20% of the arc of motion. With the possible exception of hip extension, this study supports the conclusion that, at least to age 74 years, any substantial loss of joint mobility should be viewed as abnormal and not attributable to aging and therefore should be treated much as it would be in a younger individual.

This paper describes the all-cause mortality experience, following a fracture of the hip, of 712,027 persons covered by the Medicare program from 1984 through 1987. White women experienced the lowest mortality rate (17.2 per 1000 person-months), followed by Black women (22.9 per 1000 person-months), Black men (33.5 per 1000 person-months), and White men (33.7 per 1000 person-months). The observed race-sex differences in survival were found at all ages and regardless of the number of comorbid conditions listed with the discharge diagnosis. While these data demonstrate marked race-sex differences in survival following hip fracture, the cause of these differences is not immediately apparent and demands further investigation.

A case is presented of an elderly patient with synchronous ureteral/bladder/urethral transitional cell carcinoma and prostatic adenocarcinoma. In a subsequent review of 1,104,269 cancer patients in the literature, the reported prevalence of multiple primary malignant neoplasms (MPMN) varies between 0.734% and 11.7%. It appears that MPMN might occur more frequently than can be explained on the basis of random chance. As expected, the incidence of developing MPMN is noted to rise with increasing age. In addition, the preponderance of men with MPMN is caused primarily by the high frequency of prostatic cancer. Current studies and research need to address the potential of older cancer patients being at higher risk of second primaries.
