骨质疏松与老年髋部骨折

目的观察60岁以上的老年人与同性别年轻人骨密度峰值的差别,老年髋部骨折患者与同年龄组健康老年人骨密度的差异,及近11年来老年髋部骨折发生的一般规律。探索老年髋部骨折与骨质疏松的关系。方法测量20~35岁年龄组正常男性和女性的腰椎、股骨颈、Ward三角及大转子区的骨密度值;测量60岁以上健康老年男性及女性各年龄组的骨密度值;测量60岁以上新入院髋部骨折男、女性患者的骨密度值。所有结果均进行统计学处理。统计近11年来收治的445例60岁以上髋部骨折患者的年龄、性别分布规律。结果60岁以上的男、女性老年人与同性别年轻人骨密度比较,差异有显著性意义(P<0.01);健康老年男性骨密度明显高于同年龄组女性(P<0.01);健康老年男、女性骨密度明显高于同年龄组髋部骨折患者(P<0.01);对近11年来收治的445例老年髋部骨折患者的性别、年龄进行比较,差异无显著性意义。结论虽然老年骨折常由外伤引起,但骨质疏松是老年人骨折的重要内在因素;尽管老年男性比女性骨密度高,但两者的骨折机会及骨折发生率基本相同。     

广州地区骨质疏松症合并髋部骨折骨密度阈值的研讨

目的 了解广州地区骨质疏松髋部骨折的骨密度阈值为预防髋部骨折提供有用的数据和措施。方法 调查和分析133例年龄在65岁以上，受伤后两周内入院治疗的男女性不同类型的髋部骨折患者的骨密度情况，分析及提出髋部骨折的骨密度阈值。结果 无论何种类型的股骨颈骨折男性的骨密度均比女性高，差异有显著性，虽然男性股骨颈骨折平均BMD≥-2.31SD；但其中73％病例有1个部位骨密度≤-2.5SD。女性股骨颈骨折和男，女性粗隆间骨折髋部骨量损失相近似，都明显低于男性股骨颈骨折。结论 股骨颈骨折的类型以及粗隆间骨折Garden分型与骨量无关；外伤后女性发生股骨颈骨折或粗隆间骨折与骨量无关。男性发生粗隆间骨折与骨量丢失更多有关。男女性骨质疏松髋部骨折都可以用骨密度减低2．5SD作为骨折的阈值。

Does bone mineral density affect hip fracture severity?

The association between hip fracture and reduced bone mineral density is well documented, with reduced bone mineral density predisposing to fracture. However, it is unknown whether an association exists between the magnitude of bone density lost and the severity of the hip fracture sustained. One hundred forty-two patients (96 women, 46 men) with a mean age of 74 years (range, 49-92 years) who sustained a hip fracture following a simple ground-level fall and were treated for this injury were reviewed. All patients had undergone dual-energy x-ray absorptiometry bone scanning of the contralateral hip and lumbar spine. Fractures were classified as intra- or extracapsular or subtrochanteric and then subclassified by degree of severity as simple (stable) or multifragmentary (unstable) fracture patterns.Although a low hip bone mineral density (T- or Z score <2.5) was associated with an increased risk of extracapsular fracture (P=.025) compared with other fracture types, no association existed between bone mineral density and the severity of the resultant hip fracture. Although an association exists between bone mineral density and the risk of fragility fractures, the results of the current study suggest that the severity of hip fractures does not follow this correlation. Therefore, no assumption can be made about bone mineral density of the proximal femur based on the severity of the fracture observed on plain radiographs.     

Bone mineral density in the femoral neck increases after hip resurfacing: a cohort with five-year follow-up

Hip resurfacing is an effective treatment modality for arthritis of the hip in carefully selected patients; however, its use remains controversial due to its higher revision rates compared with conventional total hip replacement surgery. The most frequent reason for revision is femoral neck fracture, and preoperative bone mineral density is an important factor when considering the option of hip resurfacing. Whilst reduction in bone mineral density following total hip replacement is well documented, little is known about the long-term changes in femoral neck bone mineral density after hip resurfacing. We followed 15 patients (ten male and five female) who underwent unilateral hip resurfacing for osteoarthritis with standardised dual energy X-ray absorbiometry scans at two weeks, three months, one year, two years and five years postoperatively to determine changes in the femoral neck bone mineral density. Both males and females initially had decreases in bone mineral density at three months postoperatively, but had gradual mean increases to 119% of their initial measurements by five years. This study demonstrates that femoral neck bone mineral density increases after hip resurfacing and that this increase continues for at least five years.     

Nulliparity and fracture risk in older women: the study of osteoporotic fractures.

Whether nulliparity increases fracture risk is unclear from prior studies, which are limited by small samples or lack of measured bone mineral density. No study has evaluated whether the effect of parity differs by skeletal site. We prospectively analyzed the relationship of parity to the risk of incident nontraumatic hip, spine, and wrist fractures in 9704 women aged 65 years or older participating in the Study of Osteoporotic Fractures to determine if parity reduces postmenopausal fracture risk, and if so, if this risk reduction is (1) greater at weight-bearing skeletal sites and (2) independent of bone mineral density. Parity was ascertained by self-report. Incident hip and wrist fractures were determined by physician adjudication of radiology reports (mean follow-up, 9.8 years) and spine fractures by morphometric criteria on serial radiographs. The relationship of parity to hip and wrist fracture was assessed by proportional hazards models. Spine fracture risk was evaluated by logistic regression. Compared with parous women, nulliparous women (n = 1835, 19%) had an increased risk of hip and spine, but not wrist, fractures. In multivariate models, parity remained a significant predictor only for hip fracture. Nulliparous women had a 44% increased risk of hip fractures independent of hip bone mineral density (hazards ratio, 1.44; 95% CI, 1.17-1.78). Among parous women, each additional birth reduced hip fracture risk by 9% (p = 0.03). Additionally, there were no differences in mean total hip, spine, or radial bone mineral density values between nulliparous and parous women after multivariate adjustment. In conclusion, childbearing reduces hip fracture risk by means that may be independent of hip bone mineral density.     

Bone mineral density of the hip measured with dual-energy X-ray absorptiometry in normal elderly women and in patients with hip fracture

Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry (DEXA) in 133 normal females on five regions of the femoral site: neck, trochanteric, intertrochanteric, Ward's triangle, and total area of the proximal femur. One hundred and twenty-five women (56 older than 65, range 65-97, and 69 with an age range of 21-65) were also examined for spinal bone mineral density. The mean in vivo precision (CV%) of the measurements with repositioning assessed on five young and eight elderly patients was ranged from 0.7% to 1.7% but lower for Ward's triangle (CV = 2.95% and 3.87%). Between 30 and 90 years, a linear age-related bone mineral decrease was found at all sites with a similar magnitude of bone loss for the femoral neck, total or intertrochanteric regions (-33% to -39%). A greater decrease was found for the Ward's triangle region (-61%). In the subgroup of elderly women (65-97 years old), the lumbar BMD measured with an anteroposterior incidence did not decrease significantly with age, contrasting with an average 27% decrease of the BMD of the hip between 65 and 90 years of age. In addition, 31 patients suffering either from a cervical (n = 12) or pertrochanteric (n = 19) fracture were measured on their contralateral femur 15 to 30 days after the fracture event. The mean calculated BMD values were, depending on the measured area, from 14% to 21% lower than those reported for age-matched controls (z-score from -1.11 to -0.65). A fracture threshold was determined for each site from this population and the elderly controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Better discrimination of hip fracture using bone density,geometry and architecture

Bone density predicts the risk of hip fracture. Because hip strength is determined by bone geometry and architecture as well as density, we tested which variables in geometry and architecture were independent discriminators of hip fracture and, if combined with density, improved the discrimination of fracture from non-fracture over bone density alone. The design was a case-control study. The subjects were Caucasian women over the age of 60 years who had sustained a hip fracture after the age of 58 years (n=22), and controls matched for age and weight (n=43) and unmatched controls (n=317) with no history of hip fracture. Variables in density, geometry and architecture were obtained from dual-energy X-ray absorptiometry images and from radiographs of the upper end of the femur. In a univariate model, of the measures of bone mass, the best discriminator of hip fracture was bone mineral density of the neck of femur; of the geometric measurements, it was hip axis length; and of the measurements of bone architecture, it was Singh grade. In a multivariate model, these three variables were shown to be independent discriminators of hip facture. When hip axis length was combined with bone mineral density, there was significant improvement in discrimination of hip fracture (p=0.014), and when Singh grade was combined with hip axis length and bone mineral density there was a further significant improvement (p=0.002). In logistic regression models using hip axis length and Singh grade adjusted for femoral neck bone mineral density, age and weight, the area under the receiver-operating characteristics (ROC) curve for femoral neck density, hip axis length and Singh grade together was significantly greater than for femoral neck density alone (p=0.006). Models that combine bone mass (density), geometry (hip axis length) and architecture (Singh grade) significantly improve the discrimination of hip fracture over bone density by itself. If these models can be shown to be equally useful in predicting hip fracture prospectively and can be obtained from dual-energy X-ray absorptiometry, their use will increase the ability to identify subjects at most risk of hip fracture.     

Bone mineral density in the distal radius in a healthy Japanese population and in relation to fractures of the distal radius.

Changes in bone mineral density with age were measured in the distal radius of healthy adults using dual energy X-ray absorptiometry. A total of 2789 healthy women (20-95 years old) and 1255 healthy men (20-87 years old), and 72 women (52-94 years old) and 23 men (51-79 years old) with fractures of the distal radius were assessed. Bone mineral density remains relatively stable in men despite aging, and was significantly higher than in women in every decade. In women aged 70 years and more, the bone mineral density was significantly lower in the fracture group than the non-fracture group. In men with fractures of the distal radius, there were no significant differences between bone mineral density and age. In the fracture groups loss of radial inclination after reduction correlated with decreased bone mineral density, but there was no significant regression between bone mineral density and the decrease in radial length or palmar tilt.
