骨质疏松是一个解剖上的综合征,特点是骨小梁减少、骨皮质变薄,而无骨基质增多、钙化障碍的骨软化症表现,也无甲状旁腺功能亢进(甲旁亢)的骨吸收增加和骨纤维变性。骨质疏松是由于骨吸收轻度超过骨形成,可以是局限性或全身性。全身性骨质疏松(原发性或继发性)使骨脆性增加,常引起脊椎压缩性骨折和股骨颈骨折。正常骨结构形成的新概念在成人,骨组织层层形成,这些骨组织层(或板层)由成骨细胞形成。当板层形成时,每层中有许多成骨细胞,同时深入骨组织中转
Osteoporosis is an anatomical syndrome characterized by reduced trabecular bone, thinning of the cortical bone, absence of increased bone matrix, osteomalacia with calcified disorders, and absence of hyperparathyroidism (hyperparathyroidism) Increased bone resorption and bone fibrosis. Osteoporosis is due to the fact that bone resorption is slightly more than bone formation and can be localized or generalized. Systemic osteoporosis (primary or secondary) increases bone fragility, often causing vertebral compression fractures and femoral neck fractures. The new concept of normal bone structure is formed at the adult, layers of the bone tissue, which are formed by osteoblasts. When the lamella is formed, there are many osteoblasts in each layer, with simultaneous in-depth bone tissue turnover
