Low-trauma fractures indicate increased risk of hip fracture in frail older people.
Summary of "Low-trauma fractures indicate increased risk of hip fracture in frail older people."
This study aims to investigate risk of subsequent fractures after low-trauma fracture in frail older people. 1412 elderly residents (mean age 86.2, SD 7.0 years, female 77%) were recruited from aged care facilities in Australia. Residents were assessed and then followed for any fracture for two years and hip fractures for at least five years. Residents with and without a newly acquired fracture in the first two years were compared for risk of subsequent hip fracture. Residents with a non-hip fracture in the first two years had an increased risk of subsequent hip fracture for about 2.5 years, while those with a hip fracture had a similar risk over the whole period, compared with those with no fracture. During these 2.5 years, 60, 28 and 6 subsequent hip fractures occurred in the non-fracture group (n=953), the non-hip fracture group (n=194) and the hip fracture group (n=101) respectively resulting in the probability of subsequent hip fracture of 8.0%, 19.9% and 10.4% respectively. Compared with the non-fracture group, the HR was 2.82 (95%
CI:
1.73-4.59; P<0.001) for the non-hip fracture group and 1.48 (95%
CI:
0.63-3.49; P=0.37) for the hip fracture group after adjusting for age, sex, residence type, calcaneal broadband ultrasound attenuation, fracture history, weight, lower leg length , immobility, cognitive function and medications. Frail institutionalized older people with newly acquired fractures are at increased risk of subsequent hip fracture for the next few years. Accordingly, despite their advanced age, they are a high priority target group to investigate interventions that might reduce the risk of hip fracture.

Medical and Biotech [MESH] Definitions
Skull Fractures
Fractures of the skull which may result from penetrating or nonpenetrating head injuries or rarely BONE DISEASES (see also FRACTURES, SPONTANEOUS). Skull fractures may be classified by location (e.g., SKULL FRACTURE, BASILAR), radiographic appearance (e.g., linear), or based upon cranial integrity (e.g., SKULL FRACTURE, DEPRESSED).
Frail Elderly
Older adults or aged individuals who are lacking in general strength and are unusually susceptible to disease or to other infirmity.
Skull Fracture, Depressed
A skull fracture characterized by inward depression of a fragment or section of cranial bone, often compressing the underlying dura mater and brain. Depressed cranial fractures which feature open skin wounds that communicate with skull fragments are referred to as compound depressed skull fractures.
Fractures, Spontaneous
Fractures occurring as a result of disease of a bone or from some undiscoverable cause, and not due to trauma. (Dorland, 27th ed)
Carotid-cavernous Sinus Fistula
An acquired or spontaneous abnormality in which there is communication between CAVERNOUS SINUS, a venous structure, and the CAROTID ARTERIES. It is often associated with HEAD TRAUMA, specifically basilar skull fractures (SKULL FRACTURE, BASILAR). Clinical signs often include VISION DISORDERS and INTRACRANIAL HYPERTENSION.
