概括
关节塑造术后周围假肢骨矿物质密度 (BMD) 损失是一个重大问题. 本综述检查了BMD测量工具,骨损失的原因,以及治疗药物治疗方法,如 teriparatide 和 denosumab,以改善结果.
科学领域:
- 整形外科手术 整形外科手术
- 生物医学工程 生物医学工程
- 药理学 药理学是指药理学的学科.
背景情况:
- 关节整形手术 (全膝关节整形手术,单部位膝关节整形手术,全关节整形手术) 是治疗晚期关节疾病的主要方法.
- 一个常见的并发症是周围的假肢骨矿物质密度 (BMD) 损失,这增加了植入物松和骨折的风险.
研究的目的:
- 审查当前评估周围假肢骨干的方法.
- 分析导致周围假肢骨损伤减少的因素.
- 讨论药理干预措施,以减轻骨质损失和增强术后结果.
主要方法:
- 关于周围假肢骨损伤评估技术 (DEXA,QCT,HRpQCT) 的当前文献的综述.
- 分析导致骨损失的因素,包括应激屏蔽,手术技术,患者特征和术后护理.
- 药理学药剂 (特里巴拉提德,登苏马布,传统中医药化合物) 的评估,以保护周围假肢骨.
主要成果:
- DEXA,QCT和HRpQCT是关键的BMD评估工具,每个都有特定的优势和局限性 (例如,工件干扰,成本,辐射,站点限制).
- 压力屏蔽,手术技术,患者因素 (年龄,骨质疏松症) 和术后管理的差距是导致骨损失的主要驱动因素.
- 合成代谢剂 (teriparatide),抗吸收剂 (denosumab) 和TCM药物在维持周围假肢骨质损伤方面表现出有效性.
结论:
- 周围假肢骨损失是关节整形术后的一个关键挑战.
- 目前的监测和药理学策略有希望,但面临着可访问性和标准化问题.
- 未来的研究应该优先考虑个性化骨损伤管理,成本效益的监测和组合疗法的长期研究,以改善植入物存活率和患者的生活质量.

Bone Disorders
4.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Bone Remodeling
38.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
