Abstract
BackgroundIn general there is a lack of data on osteoporosis and fracture in men; this also includes low-energy distal radius fractures. The objectives of this study were to examine BMD and identify factors associated with distal radius fractures in male patients compared with controls recruited from the background population.MethodsIn a 2-year period, 44 men 50 years or older were diagnosed with low-energy distal radius fractures, all recruited from one hospital. The 31 men who attended for osteoporosis assessment were age-matched with 35 controls. Demographic and clinical data were collected and BMD at femoral neck, total hip and spine L2-4 was assessed by dual energy X-ray absorptiometry.ResultsApart from weight and living alone, no significant differences were found between patient and controls for demographic variables (e.g. height, smoking) and clinical variables (e.g. co-morbidity, use of glucocorticoids, osteoporosis treatment, falls and previous history of fracture). However, BMD expressed as T-score was significant lower in patients than in controls at all measurement sites (femoral neck: -2.24 vs. -1.15, p < 0.001; Total hip: -1.65 vs. -0.64, p < 0.001; Spine L2-4: -1.26 vs. 0.25, p = 0.002). Among the potential risk factors for fracture evaluated, only reduced BMD was found to be significantly associated with increased risk for low-energy distal radius fractures in men.ConclusionThe results from our study indicate that reduced BMD is an important risk factor for low-energy distal radius fracture in men. This suggests that improvement of BMD by both pharmacological and non-pharmacological initiatives may be a strategy to reduce fracture risk in men.
Highlights
In general there is a lack of data on osteoporosis and fracture in men; this includes low-energy distal radius fractures
No other risk factors were found to be significantly associated with low-energy distal radius fractures, there was a trend for low body weight
We identified all male patients with low-energy distal radius fracture including patients not attending dual energy X-ray absorptiometry (DXA)-measurements at the osteoporosis centre
Summary
In general there is a lack of data on osteoporosis and fracture in men; this includes low-energy distal radius fractures. The objectives of this study were to examine BMD and identify factors associated with distal radius fractures in male patients compared with controls recruited from the background population. Compared to women there is a general lack of data on distal radius fractures in men including data on prevalence of osteoporosis and risk factors [2,3,4]. Osteoporosis has been reported to be more frequent in male distal radius fracture patients compared to control subjects and reference populations [2,5,6,7]. There is a lack of data exploring the role of The objective of this prospective case-control study was to compare BMD at spine and hip in male lowenergy distal radius fracture patients with age-matched controls and to search for factors associated with increased risk for distal radius fractures
