Radial and humeral fractures as predictors of subsequent hip, radial or humeral fractures in women, and their seasonal variation

Abstract

Hip fractures are common in elderly women, and early risk assessment of future hip fractures is relevant in relation to prevention. We studied the predictive value of radial and humeral fractures in women. The influence of weather conditions on the risk was also studied. Women aged 20-99 years with a fracture of the distal radius (n = 1162) or proximal humerus (n = 406) were followed for 0 to 9 years. The relative risk (RR) and 95% confidence limits (CL) of subsequent fracture among women suffering radial or humeral fractures compared with the background population were calculated. Women 60-79 years of age who had suffered a fracture of the distal radius or proximal humerus had relative risks of sustaining a hip fracture of 1.9 (1.3-2.6, 95% CL) and 2.5 (1.3-3.6, 95% CL) respectively. The relative risk of hip fracture was highest within the first years following a fracture of the radius or the humerus. Women suffering an upper extremity fracture (radius or humerus) in snowy or icy weather had a marginally increased risk (RR = 1.3, 0.4-2.3, 95% CL and RR = 1.8, 0.3-3.4, 95% CL) for a later hip fracture. A woman 50 years old with a radial or a humeral fracture had an estimated residual lifetime risk of sustaining a subsequent hip fracture of 17% and 16% respectively compared with 11% for the background population.(ABSTRACT TRUNCATED AT 250 WORDS)

Proximal Humeral Fracture as a Risk Factor for Subsequent Hip Fractures

“…In studies in which this relationship was evaluated 20,22,35 , sample sizes were small, the subjects were from a single geographic region, or the authors did not control for important risk factors when evaluating the times of subsequent fractures.…”

“…Proximal humeral fractures represent a unique subset of osteoporotic fractures; up to 73% of these fractures occur in women, making them the second most common upper-extremity fractures [17][18][19] . A proximal humeral fracture also appears to be a risk factor for the subsequent occurrence of other incident fractures, including those at the hip 20,21 . Johnell et al evaluated the timing of subsequent fragility fractures after an individual had sustained an incident fracture of the spine, proximal part of the humerus, or hip.…”

Treatment of established osteoporosis: a systematic review and cost-utility analysis

“…20 The likelihood that any individual will suffer an osteoporotic fracture is considerable. In many Western countries, the remaining lifetime probability of a hip fracture in women at the menopause lies between 15% and 28% [21][22][23] but varies from country to country. In this study, hip fracture rates in Edinburgh have been used (see chapter 4) and, based on these figures, the remaining lifetime risk at 50 years of age is 14.2% in women and 5.2% in men ( Table 1).…”

Bone Mineral Density and Vitamin D Status Among African American Children With Forearm Fractures

“…In adults, forearm fractures are associated with bone health deficits, including lower bone mineral density (BMD), and are predictors of future osteoporosis-related fractures. [7][8][9][10] Similarly, studies of predominantly healthy white children with forearm fractures demonstrate an association with lower BMD relative to peers without forearm fractures. [11][12][13][14][15][16] Other factors associated with forearm fracture risk in white children include low dietary calcium intake, 17 low dietary milk intake, 17 and high BMI.…”
