摘要
研究了36名成人髂骨活检标本的骨小梁三维结构与年龄增长的关系。两性的 TBV 均随年龄增加而下降,以女性为著。女性 Tb.Th 随年龄增加明显下降。两性的 Tb.N 和 Tb.Sp 与年龄呈显著负相关,女性更为明显。结果表明,随着年龄增加骨小梁逐渐丢失,骨小梁间距增大,骨小梁网状结构破坏。此外,还对男女骨小梁丢失的不同方式进行了探讨,提出应注意骨质疏松的预防。
A study was made of the relationship between the three-dementional structure oftrabeculae of iliac crest and aging in 36 normal chinese adults.In both sexes,TBVwas shown to be declined with aging,especially in the females.A significant decre-ase in Tb.Th with aging was also noted in the females.There were significant ne-gative correlations of Tb.N and Tb.Sp with aging in both sexes.It seems,however,to be more pronounced in the females.The data indicated that with aging theprocess of bone loss proceeded gradually,which was evidenced by the trabecular se-paration and the destruction of its network.At the end,different models were sug-gested to reveal the pathogenesis of bone loss in both sexes.The authors suggestedthat more attention should be paid to the prevention from osteoporosis.
