概括
膝关节置换中的生殖神经点与本地膝关节相似,但较小的神经直径和纤维化可能会影响术后疼痛的射频切除疗效.
科学领域:
- 人体解剖学 解剖学 解剖学
- 疼痛管理 疼痛管理
- 整形外科手术 整形外科手术
背景情况:
- 慢性膝关节关节炎通常需要关节置换,这可能导致持续的术后疼痛.
- 无线电频率剥离用于慢性膝关节疼痛,但在膝关节关节整形术后,与本地膝关节相比,效果较差.
- 了解假膝关节的生殖神经解剖学对于优化疼痛管理策略至关重要.
研究的目的:
- 为了比较本地与假肢尸体膝盖的生殖神经点.
- 为了确定膝关节关节整形术后是否需要对生殖神经点进行修改.
- 为了研究可能解释在假膝关节中减少射频剥离功效的解剖学差异.
主要方法:
- 详细剖析了10个本地和10个假肢尸体膝关节的生殖神经.
- 神经来源,轨道,目标点,直径和靠近动脉血管的比较.
- 进行了乳动脉注射以增强可视化.
主要成果:
- 阴茎神经点显示,原生膝关节和假膝关节之间的差异很小.
- 假膝盖表现出纤维的附着性,该纤维附着性是石神经 (IPBSN) 的下皮骨分支.
- 较小的平均神经直径和变化的超中位生殖神经 (SMGN) 接近关节线在假膝盖中被注意到. 在两组中都观察到超侧生殖神经 (SLGN) 目标附近没有动脉分支.
结论:
- 假膝盖具有类似的生殖神经位置,但与本地膝盖相比,直径较小和IPBSN纤维化.
- 降低神经直径和SLGN附近动脉里程碑的潜在缺失可能会影响准准确度.
- 仅仅是解剖学变异并不能完全解释在假膝关节中射频除效率下降的原因.

Knee Joint
3.1K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Anatomical Positions
19.6K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology
26.7K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements
15.4K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Cerebrum: Anatomical Overview II
4.5K
Each cerebral hemisphere can be divided into three main regions. The outermost region, the cerebral cortex, is a thin layer (2 to 4 millimeters thick) made up of gray matter, consisting of neuron cell bodies, dendrites, glial cells, and blood vessels. The middle region, or white matter, is primarily composed of myelinated nerve fibers organized into three types of large tracts: association fibers, commissures, and projection fibers. Association fibers connect different areas within the same...

Diencephalon: Anatomical Regions
5.0K
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...
