BACKGROUND: Although foot and @entity1171 are among the most common nonspinal @entity174 occurring in older @entity1 , little is known about their epidemiology. This study was designed to determine the incidence of and risk factors for foot and @entity1171 in a cohort of 9704 elderly, nonblack @entity1 enrolled in the multicenter Study of @entity3604 . METHODS: At their first clinic visit, between 1986 and 1988, the @entity1 provided information regarding lifestyle, subjective health, and function. Bone mineral density was measured in the proximal and distal parts of the radius and in the calcaneus. The @entity1 were followed for a mean of 10.2 years, during which time 301 of them had a foot @entity174 and 291 had an @entity1171 . The @entity174 were classified with use of a modification of the Orthopaedic @entity130 Association's guidelines. RESULTS: The incidence of foot @entity174 was 3.1 per 1000 @entity1 -years, and the incidence of @entity1171 was 3.0 per 1000 @entity1 -years. The most common @entity1171 was an isolated fibular @entity174 (prevalence, 57.6%), and the most common foot @entity174 was a @entity174 of the fifth metatarsal (56.9%). @entity1 who sustained an @entity1171 had been slightly younger at the time of study enrollment than the @entity1 who did not sustain such a @entity174 (71.0 compared with 71.7 years), they had a higher body mass index (27.6 compared with 26.5), and they were more likely to have fallen within the twelve months prior to filling out the original questionnaire (38.1% compared with 29.7%). The appendicular bone mineral density was not significantly different between these two groups of subjects. @entity1 who sustained a foot @entity174 had a lower bone mineral density in the distal part of the radius (0.345 g/cm (2) compared with 0.363 g/cm (2) ) and a lower calcaneal bone mineral density (0.394 g/cm (2) compared with 0.404 g/cm (2) ) than the @entity1 without a foot @entity174 , they were less likely to be physically active (62.3% compared with 67.8%), and they were more likely to have had a previous @entity174 after the age of fifty (45.5% compared with 36.8%) and to be using either long or short-acting @entity1245 . CONCLUSIONS: Overall, foot @entity174 appeared to be typical @entity3604 , whereas @entity1171 occurred in younger @entity1 with a relatively high body mass index.
