科学领域:
- 脊柱外科手术 脊柱外科手术
- 人体解剖学 解剖学 解剖学
- 放射学 放射学是一门学科.
背景情况:
- 侧腰间体融合 (LLIF) 和斜腰间体融合用于脊柱纠正.
- LLIF与神经损伤的风险更高有关,而斜腰间体融合与血管损伤的风险更高.
研究的目的:
- 引入基于磁共振成像 (MRI) 的分类系统,用于psoas肌肉形态.
- 为了评估相邻的神经血管结构相对于psoas肌肉的位置.
- 根据psoas形态来评估手术轨迹的安全性.
主要方法:
- 一项横截面研究分析了100名患者的MRI扫描.
- 体形态被分为三种类型 (A,B,C) 基于其腹边缘相对于脊椎体的位置.
- 修改后的斜走廊和偏好的侧腰间体融合 (LLIF) 轨迹在psoas形态和神经损伤的定义"危险区域"方面进行了测量和分析.
主要成果:
- 体形态不同,其中44个被归类为A,27个为B,29个为C.
- 修改后的斜走廊在三个类 (A:8.99毫米,B:8.10毫米,C:4.66毫米) 之间有显著差异.
- 在A类患者中,LLIF轨迹在34.1%的A类,3.7%的B类和0.0%的C类患者中与"危险区域"相交,这表明A类患者的风险明显更高.
结论:
- 虽然提供了最大的走廊,但在LLIF期间具有最高的神经损伤风险.
- C类psoas形态具有最窄的走廊,但没有危险的LLIF轨迹的风险.
- 拟议的分类系统有助于预测和潜在地减轻与LLIF相关的外科风险.

Classification of Skeletal Muscle Fibers
56.1K
Skeletal muscles continuously produce ATP to provide the energy that enables muscle contractions. Skeletal muscle fibers can be categorized into three types based on differences in their contraction speed and how they produce ATP, as well as physical differences related to these factors. Most human muscles contain all three muscle fiber types, albeit in varying proportions.

Spinal Nerves: Plexus II
526
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

Fascicle Arrangement in Skeletal Muscles
1.8K
Fascicles are bundles of muscle fibers in a skeletal muscle. Muscle fascicle arrangement is directly associated with the power and range of motion of various muscles. The configuration of these fascicles can vary, leading to different functional outcomes.
The four primary types of muscle based on fascicle arrangement are:

Muscles of the Abdomen
1.1K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

Spinal Nerves: Plexus I
797
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
