概括
与固体螺丝相比,管螺丝在Lisfranc关节损伤中显示出更高的断裂率. 然而,这种增加的螺丝断裂并没有对患者的功能结果产生负面影响.
科学领域:
- 整形外科手术 整形外科手术
- 生物力学 生物力学
- 创伤学 创伤学 创伤学
背景情况:
- 里斯弗朗克关节受伤严重破坏了足部的生物力学.
- 用螺丝进行开放式减少和内部固定 (ORIF) 是对Lisfranc伤害的常见治疗方法.
- 螺丝断裂是常见的并发症,但与螺丝类型的关联仍未得到充分研究.
研究的目的:
- 为了确定Lisfranc损伤中螺丝断裂的危险因素.
- 分析螺丝故障的时间,模式和临床影响.
- 为了比较与不同螺丝类型相关的结果.
主要方法:
- 多中心回顾性队列研究分析了72名患有Lisfranc损伤的患者.
- 根据螺丝类型,患者被分为两组:管 (n=31) 和固体 (n=41).
- 对48名患者 (24人/组) 进行了年龄和性别匹配的分析.
主要成果:
- 螺丝断裂发生在管螺丝组 (28.6%) 与固体螺丝组 (3.6%) 相比的频率明显增加.
- 头螺丝的使用被确定为破裂的重要风险因素 (OR 0.132,p=0.0167).
- 尽管破裂率较高,但管螺丝组的最终AOFAS分数更好 (95.00比90.00,p=0.031).
结论:
- 导管螺丝与Lisfranc损伤固定中破裂的风险更高有关.
- 这种增加的螺丝断裂似乎不会对长期的功能结果产生不利影响.
- 进一步的研究可能会探索利斯弗朗克损伤的最佳螺丝选择.

01:26Factors Affecting the Risk of Infection
12.3K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

01:27Fractures: Bone Repair
3.7K
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...
