概括
在前十字带 (ACL) 重建过程中,内部支架增强显示,与标准ACL重建相比,重裂较少. 然而,功能性结果在增强和非增强组之间是相似的.
科学领域:
- 整形外科手术 整形外科手术
- 运动医学 运动医学
- 生物机械工程 生物机械工程
背景情况:
- 前十字带 (ACL) 损伤在运动员中很常见,通常需要手术重建.
- 自体移植经常用于ACL重建,但移植失败和重裂仍然令人担忧.
- 内部支架增强是一种新的技术,旨在提高移植的稳定性并降低失败率.
研究的目的:
- 为了比较前十字带 (ACL) 重建的临床结果,使用带有和没有内部支架增强的自体移植.
- 评估内部支架增强对功能评分和术后并发症的影响.
- 为了确定内部支架增强是否减少了ACL重裂的发生率.
主要方法:
- 一个回顾性分析前性收集的数据从患者接受ACL重建与腿筋或四头肌肌自移植.
- 患者被分为两组:接受内部支架增强的患者和没有接受的患者.
- 使用Lysholm和Tegner功能评分评估了临床结果,并记录了手术后并发症,并在各组之间进行了比较.
主要成果:
- 在内部支架增强组和非增强组之间没有观察到术后功能评分 (Lysholm,Tegner) 的显著差异.
- 内部支架增强组的ACL复发率较低 (1.8%),与非增强组 (7.3%) 相比.
- 这两个组的并发症率,包括关节纤维化和血栓形成,在两组之间是可比的,而非增强组的感染发病率略高.
结论:
- 在ACL重建中进行内部支架增强可能会降低与标准自移植重建相比重裂的风险.
- 尽管复发率较低,但在一年后的随访中,内部支架增强并没有导致功能结果的显著改善.
- 需要进一步研究更大的样本大小和更长的随访期,以充分阐明ACL重建中内部支架增强的长期益处和潜在风险.

02:37Restarting Stalled Replication Forks
DNA replication is initiated at sites containing predefined DNA sequences known as origins of replication. DNA is unwound at these sites by the minichromosome maintenance (MCM) helicase and other factors such as Cdc45 and the associated GINS complex.The unwound single strands are protected by replication protein A (RPA) until DNA polymerase starts synthesizing DNA at the 5’ end of the strand in the same direction as the replication fork. To prevent the replication fork from falling apart, a...

01:30Frames
Frames are essential components of various mechanical and structural systems used daily. These structures are known for their stability and ability to bear heavy loads. A frame is constructed using two-force and multi-force members, interconnected using pin joints. In contrast, trusses are made entirely of two-force members.
Frames are versatile and widely used in various applications such as structural supports for beams and columns, automobile chassis construction, and in the construction...

01:15Reinforced Brick Masonry
Reinforced brick masonry is an advanced construction technique that enhances the structural integrity of brick walls by incorporating steel reinforcements. These reinforcements are either placed within the hollow cores of bricks or sandwiched between two layers of masonry, known as wythes, and are then secured in place with grout. Grout is a fluid mixture composed of Portland cement, aggregate, and water, providing the necessary bonding agent for the steel and brick.

01:22Fiber Reinforced Concrete
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...
01:25Effects of Creep
Creep in concrete, the gradual deformation under prolonged stress, significantly impacts the integrity of structures. For reinforced concrete beams, it can be a vital design consideration, as it increases deflection, sometimes necessitating additional design measures. In columns, especially slender ones under eccentric loads, creep can cause buckling, compromising their stability. However, creep can be beneficial in indeterminate structures by mitigating stresses that arise from shrinkage,...
