概括
甲状腺内富血小板血 (PRP) 没有改善骨折愈合或功能恢复在老年患者内骨折,尽管早期的X光效益. 对于特定的患者群体需要进行进一步的研究.
科学领域:
- 整形外科手术 整形外科手术
- 再生医学是一种再生医学.
- 生物材料科学 生物材料科学
背景情况:
- 在老年人中,胸腔间骨折是具有挑战性的,因为骨愈合不良和高并发症率.
- 富血小板血 (PRP) 显示出骨再生的潜力,但对骨质疏松性骨折的证据有限.
- 骨髓内PRP针对骨折部位的血管髓,不同于骨髓外注射.
研究的目的:
- 评估内PRP对骨折愈合和骨折间骨折的老年患者的临床结果的影响.
- 测试假设,与安慰剂相比,内PRP可以加速骨早期愈合,并改善术后功能恢复.
主要方法:
- 单中心,双盲,随机对照试验 (RCT) 涉及60岁以上的患者,骨骨折.
- 患者在手术期间接受了5毫升的自身PRP或5毫升的正常盐水,以及标准的脑髓钉.
- 随访评估包括放射性结合 (RUSH评分) 和功能性结果 (哈里斯部评分,巴特尔指数,德·莫顿移动性指数) 在各种术后间隔.
主要成果:
- 在PRP (n=40) 和对照组 (n=44) 之间,基线特征没有显著差异.
- PRP组在2周后显著增强了早期放射性愈合 (RUSH分数12.0对10.5;P<0.001),但这种效应没有持续.
- 两组之间在6周和6个月后的骨循环标记或功能结果中没有发现显著差异.
结论:
- 内PRP并没有改善中长期骨折愈合或老年患者的功能结果.
- 虽然早期的放射疗法得到了增强,但内PRP的临床益处没有持续.
- 在这种患者群体中,PRP可能具有有限的临床实用性,因此需要在特定子组或经过修改的方案中进行进一步的研究.

The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Bone Disorders
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...
