Hip fracture, the most dramatic complication of osteoporosis, constitu
tes a serious health problem of the elderly, with great socioeconomic
consequences. Hip fracture epidemiology has been studied by many inves
tigators. Until now, reported studies in Greece include either data fr
om only one region, or they do not include all the epidemiological par
ameters concerning hip fractures. We studied hip fractures that occult
ed in Greece in 1992 and compared the findings with those of previous
years (1977, 1982, 1987), in order to identify age and sex incidence a
nd increase rate during 1977-1992. There has been an average annual in
crease of 7.6%, thus total hip fractures in Greece increased from 5,10
0 in 1977 (54.75 fractures/100,000 inhabitants) to 10,953 in 1992 (107
.30 fractures/100,000 inhabitants). In 1992, 70% of the patients were
women. During the 1977-1992 period, age-adjusted incidence for people
aged over 50 increased in both sexes (from 173.54 fractures/100,000 in
habitants in 1977 to 314.07 fractures/100,000 inhabitants in 1992, an
increase of age-adjusted incidence of 80.97%). Approximately 50% of th
e patients in 1992 were aged 80 and over, whereas in 1977 there were o
nly 22.49% patients of the same age. The increase in hip fracture numb
ers is greater than expected due to population aging, suggesting the e
xistence of other factors influencing this increase. The most affected
age group is 80 and over.
