概括
用粉床融合制成的骨整形植入物表现出与现有方法相比的并发症和移除率. 脑脊液分流或健康状况不佳的患者面临更高的感染和植入物失败风险.
科学领域:
- 神经外科和生物医学工程
- 医疗植入物中的材料科学
背景情况:
- 头骨整形术可以在头骨切除术后重建头骨缺陷,但并发症需要在10-20%的病例中切除植入物.
- 造植入物的最佳材料仍然未确定,导致患者的结果变化.
研究的目的:
- 评估使用23级Ti-6Al-4V粉末床融合 (PBF) 头骨整形植入物的多学科头骨修复服务的安全性和有效性.
- 为了与现有技术比较PBF头骨移植手术的并发症和植入物切除率.
主要方法:
- 在105名使用PBF制造的23级Ti-6Al-4V植入物的患者中,对107次骨整形手术进行了回顾性分析.
- 2017年12月至2021年12月在剑桥大学医院收集的数据.
- 主要结局:移除植入物;次要结局:造术感染.
主要成果:
- 整体并发症率为22% (24/107名患者),其中10% (11/107) 需要切除植入物.
- 12% (13/107) 的患者出现了手术部位感染,导致7% (8/107) 的患者进行了植入物切除.
- 脑脊液分流位置 (HR 8.57) 和高ASA等级 (HR 6.87) 预测了更短的植入物存活时间.
结论:
- 用PBF制造的头造术显示出与文献基准可比的并发症和移除率.
- 建立的多学科服务允许量身定制的手术和未来的创新在骨整形.
- 脑脊液分流和一般健康状况不佳的患者有感染和骨整形失败的风险增加.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:31Bone Remodeling and Repair
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
