概括

一个新的"四分法则"指导了对偏远间关节 (DIPJ) 损伤的最佳基尔施纳线 (K-线) 放置. 这种方法使用简单的地标来安全和准确地插入K线,改善手术结果.

科学领域:

整形外科手术整形外科手术
手术手术手术手术手术
放射学解剖学放射学解剖学

背景情况:

遥远的关节和关节间的关节损伤很普遍,造成了重大的个人和社会负担.
操作固定通常涉及逆行跨关节基尔施纳线 (K-线) 的放置.
通过远距离间关节 (DIPJ) 进行最佳的K线通道对于对齐和减少并发症至关重要,但证据有限.

研究的目的:

识别软组织和放射性地标,以便在DIPJ中精确地定位跨关节K线.
为在DIPJ伤害的手术干预期间建立安全有效的K线插入指导方针.

主要方法:

100个未受伤的侧面 phalangeal 射线图在 sagittal 投射中的回顾性分析.
三位独立评估人员确定了理想的K线插入软组织和骨参数.
测量包括从指甲板和软组织地标到理想插入线的距离.

主要成果:

理想的K线插入线平均距离背部指甲板3.86毫米,根据性别有所不同.
插入线穿过DIPJ及其的软组织宽度的约40%.
在骨和软组织标志物之间观察到一致的关系.

结论:

一个简单的"四分法则"提供了一个可复制的方法,以实现最佳的K线通道.
进入点:中线,4毫米飞向背部指甲板.
目标:40%飞向DIPJ的背部软组织,即使没有光镜也很有用.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...
