Ultrasonography

5.9K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Endoscopic Studies II: Thoracocentesis

496
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

肘部针关节镜术提供了前部关节空间的优秀可视化,但后部可视化仍然是所有经验水平的挑战. 外科医生的经验不会显著影响针关节镜在肘部的可见性.

科学领域:

  • 整形外科手术 整形外科手术
  • 最少侵入性手术的方法
  • 解剖学可视化 解剖学可视化

背景情况:

  • 肘针关节镜的诊断能力,特别是0度查看,尚未完全理解.
  • 外科医生经验对手肘关节针关节透视术的熟练程度的影响尚未确定.

研究的目的:

  • 用针关节透视来评估肘部关节内的解剖结构的可见性.
  • 为了确定外科医生经验水平是否会影响肘部针关节透视的熟练程度.

主要方法:

  • 一项描述性的实验室研究使用了20个肘部标本和一个1.9毫米针关节镜,视角为0度.
  • 具有丰富经验 (ME,>15年) 和有限经验 (LE,≤5次手术) 的外科医生通过四个标准门户评估了18个解剖学里程碑.
  • 观察时间和可视化成功率被记录下来,并在经验组之间进行比较.

主要成果:

  • 前侧和前中侧门户为这两个体验组提供了100%的结构可视化.
  • 后门可视化显示出可变性,在ME和LE组之间可见度率或观察时间没有显著差异.
  • 特定的地标,如后侧尾和骨腔中的结构,无论经验如何,都很难可视化.

结论:

  • 针关节透视是有效的检查前肘关节空间和部关节.
  • 对后肘关节空间的可视化提出了一些挑战,这些挑战无法通过增加外科医生的经验来克服.
  • 这些发现支持针关节镜对于肘部病理的实用性,独立于外科医生的专业知识.
