概括

与传统方法相比,复杂的骨盆和骨骨折的三维 (3D) 打印并没有改善手术结果或减少并发症. 在这项研究中,术前规划的好处并没有转化为更好的临床结果.

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
医疗成像医学成像

背景情况:

骨盆和骨骨折带来了重大挑战,影响了患者的发病率和死亡率.
在管理这些复杂的骨折中,3D打印的临床实用性仍然不完全理解.

研究的目的:

评估3D模拟和打印在治疗AO/OTA 61C和62B/62C骨盆骨折和骨骨折中的有效性.
为了比较3D打印和传统治疗组之间的手术结果,并发症和生活质量.

主要方法:

成年患有AO/OTA 61C和62B/62C骨折的成年患者的回顾性队列研究 (2017-2022年).
评估的结果包括术后并发症,需要全关节整形手术 (THA),以及2年后的生活质量得分 (EQ-VAS,EQ-5D-5L,Majeed得分).
分析包括92名患者 (28名3D打印组,64名传统组).

主要成果:

3D打印和传统组在2年后的生活质量得分 (EQ-VAS,EQ-5D-5L,Majeed) 中没有发现显著差异.
关节整形术 (THA) 和术后并发症的发生率在两组之间没有显著差异.
经过调整后的分析证实,3D打印使用后,初级结果没有统计学上显著的改善.

结论:

在这项研究中,复杂的骨盆和骨骨折的3D打印并没有显示出改善的临床结果或减少并发症.
在手术前规划中观察到的3D打印的好处并没有转化为优异的患者结果.
需要进行更大规模的随机对照试验,以确定3D打印在治疗这些损伤中的作用.

Bone Remodeling

Bone Remodeling

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.

Bone Remodeling and Repair

Bone 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...
