摘要:

背景:髋关节成形患者具有较高的骨质疏松症患病率,骨质疏松症影响假体存活率,髓腔闪烁指数与骨密度均随年龄变化。
目的:探讨股骨近端髓腔闪烁指数与股骨颈骨密度的关系,提高对骨质疏松症的关注。
方法:回顾性研究57例髋关节成形患者的骨盆X射线正位片的股骨近端髓腔闪烁指数和股骨颈骨密度,探讨二者的相关性。
结果与结论:57例髋关节成形患者的股骨近端髓腔闪烁指数为1.8-4.8(3.1±0.7);髓腔闪烁指数< 3者23例,髓腔闪烁指数为3-4.7者33例,髓腔闪烁指数> 4.7者1例。年龄对髓腔类型有影响,> 60岁组烟囱型髓腔显著性多于≤ 60岁组,髓腔闪烁指数≥ 3组的骨密度显著高于髓腔闪烁指数< 3组。随着年龄增高,股骨颈骨密度降低,> 60岁组患者的股骨颈骨密度为(0.590±0.092) g/cm2,显著低于≤ 60岁组患者的股骨颈骨密度(0.751±0.235) g/cm2(P =0.000),比较发现随骨密度降低,髓腔闪烁指数均值变小。因此股骨颈骨密度与髓腔闪烁指数显著相关。

Abstract:

BACKGROUND: The prevalence of osteoporosis is high in the patients undergoing total hip arthroplasty. Osteoporosis is associated with the survival of prostheses. Both canal flare index and bone mineral density are aged-related.
OBJECTIVE: To study the cxorrelation between canal flare index of the proximal femur and bone mineral density of femoral neck, and to pay more attention to osteoporosis.
METHODS: A retrospective study of the correlation between canal flare index of the proximal femur on pelvic radiograph and bone mineral density of femoral neck was made in 57 patients undergoing total hip arthroplasty.
RESULTS AND CONCLUSION: The canal flare index were ranged 1.8-4.8 (3.1±0.7) in 57 patients. There were 23 patients in canal flare index < 3 (chimney-type medullary cavity), 33 in canal flare index between 3 and 4.7 (normal-type medullary cavity), and one in canal flare index > 4.7 (funnel-type medullary cavity). The age had an impact on the type of medullary cavity. The prevalence of chimney-type medullary cavity were significantly higher in > 60 years old group than ≤ 60 years old group, and bone mineral density of femoral neck in the group of canal flare index ≥ 3 was significantly higher than the group of canal flare index < 3. The bone mineral density of femoral neck was gradually reduced with age, and were significantly higher in ≤ 60 years old group than in > 60 years old group [(0.751±0.235) g/cm2, (0.590±0.092) g/cm2, P=0.000]. As bone mineral density reduced, canal flare index was also decreased. Experimental findings indicate that, the bone mineral density of femoral neck is significantly correlated with canal flare index.
