目的:比较骨质疏松性股骨颈骨折和转子间骨折患者在髋部骨密度及几何结构上的不同特点。方法将137例50岁以上髋部骨折的患者分为两组:股骨颈骨折组69例,男20例,女49例,年龄50-97岁(75.1±9.6),体重指数(BMI):21.6±4.1 kg/m2;股骨转子间骨折组48例,男16例,女32例,年龄50-91岁(78.1±9.1),体重指数(BMI):21.5±4.3 kg/m2。对所有患者的健侧股骨近端行双能X线骨密度仪( Dual energy X-ray absorptiometry,DXA)测定,并利用该仪器的HSA软件分析髋部几何结构参数。结果两组患者在男女构成比例、年龄、身高、体重、体重指数的比较上没有统计学差异( P<0.05);两组患者的骨密度在股骨颈区( Neck)、大转子区( Troch)、Ward区、转子间区( Inter)、全髋( Total hip)的比较上没有统计学差异( P<0.05)。两组患者在股骨颈区及转子间区的横截面积(CSA)、横截面转动惯量(CSMI)、屈曲应力比(BR)的比较上均没有统计学差异(P<0.05);两组患者在股骨颈区域的皮质骨厚度的比较上没有统计学差异(P<0.05);两组患者在转子间区域的皮质骨厚度的比较上有统计学差异( P=0.013)。结论在脆性髋部骨折的不同骨折类型的发生机制上,皮质骨变薄是引起不同髋部骨折类型的一个主要因素,尤其是对于高龄的髋部骨折患者。
目的:比較骨質疏鬆性股骨頸骨摺和轉子間骨摺患者在髖部骨密度及幾何結構上的不同特點。方法將137例50歲以上髖部骨摺的患者分為兩組:股骨頸骨摺組69例,男20例,女49例,年齡50-97歲(75.1±9.6),體重指數(BMI):21.6±4.1 kg/m2;股骨轉子間骨摺組48例,男16例,女32例,年齡50-91歲(78.1±9.1),體重指數(BMI):21.5±4.3 kg/m2。對所有患者的健側股骨近耑行雙能X線骨密度儀( Dual energy X-ray absorptiometry,DXA)測定,併利用該儀器的HSA軟件分析髖部幾何結構參數。結果兩組患者在男女構成比例、年齡、身高、體重、體重指數的比較上沒有統計學差異( P<0.05);兩組患者的骨密度在股骨頸區( Neck)、大轉子區( Troch)、Ward區、轉子間區( Inter)、全髖( Total hip)的比較上沒有統計學差異( P<0.05)。兩組患者在股骨頸區及轉子間區的橫截麵積(CSA)、橫截麵轉動慣量(CSMI)、屈麯應力比(BR)的比較上均沒有統計學差異(P<0.05);兩組患者在股骨頸區域的皮質骨厚度的比較上沒有統計學差異(P<0.05);兩組患者在轉子間區域的皮質骨厚度的比較上有統計學差異( P=0.013)。結論在脆性髖部骨摺的不同骨摺類型的髮生機製上,皮質骨變薄是引起不同髖部骨摺類型的一箇主要因素,尤其是對于高齡的髖部骨摺患者。

Objective To analyze the differences of femoral geometry and bone mineral density between osteoporotic femoral neck fractures and trochanteric fractures from DXA scans.Methods A total of 137 patients were divided into femoral neck fracture group and trochanteric fracture group.There were 69 patients in femoral neck fracture group including 20 males and 49 females ( age 50-97 years, mean 75.1 ±9.6 years, BMI 21.6 ±4.1 kg/m2 ) .There were 48 patients in trochanteric fracture group including 16 males and 32 females ( age 50-91 years, mean 78.1 ±9.1 years, BMI 21.5 ±4.3 kg/m2 ) .BMD of bilateral hip of all the patients was performed using dual-energy X-ray absorptiometry ( DXA ) , and femoral geometry parameters were analyzed using the Hip Structural Analysis (HSA) software.Results There was no statistically difference (P >0.05) in the proportion of men and women, age, height, weight, and BMI between the two groups.There was no statistically difference (P>0.05) of BMD in Neck, Troch, Ward’s region, and Inter and Total hip between the two groups.There was no statistically difference (P>0.05) in CSA, CSMI, and BR of the neck and intertrochanteric region between the two groups.There was no statistically difference (P>0.05) in the neck cortical thickness between the two groups.The cortical thickness in intertrochanteric region in patients of the trochanteric fracture group was thinner than that in femoral neck fracture group ( P<0.05 ) .Conclusion On the mechanism of fragile hip fracture, it seems that the thinning of the cortical thickness is one of the main factors for different types of the hip fracture, especially in elderly hip fracture patients.
