Abstract:
The objective of this study was to find out whether the morphology of various types of hip fractures and the mean ages of the patients had changed in a recent 10-year period. All patients aged 65 years or more with acute hip fracture admitted to Miguel Servet University Hospital in 1989-1990 (n = 457) and in 1999-2000 (n = 518) were studied. The results showed a significant increase in the incidence of displaced cervical fractures (P < 0.001) and a decrease in the incidence of nondisplaced cervical fractures (P < 0.001) in women. The incidence of different types of trochanteric fractures did not vary. No change was observed in the mean age of patients with cervical fractures, but the mean age of women with A12 trochanteric fractures was significantly higher in 1999-2000 than in 1989-1990 (P < 0.05).

Bone Remodeling
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
