Summary
Patient-specific 3D models significantly reduced fluoroscopy time during cervical foraminotomy. These models aid surgical planning and may improve outcomes for radiculopathy patients.
Area of Science:
- Neurosurgery
- Medical Imaging
- Biomedical Engineering
Background:
- Cervical foraminotomy treats radiculopathy but visualizing anatomy can be difficult.
- Minimally invasive techniques present visualization challenges.
- Patient-specific 3D models offer potential solutions.
Purpose of the Study:
- To evaluate the efficacy of patient-specific 3D printed anatomical models in cervical foraminotomy.
- To compare outcomes between 3D model-assisted surgery and standard care.
Main Methods:
- Retrospective case-controlled study design.
- Comparison of patients undergoing cervical foraminotomy with and without 3D model assistance.
- Analysis of fluoroscopy time, operative time, blood loss, and functional improvement.
Main Results:
- Statistically significant reduction in fluoroscopy time (21.8s vs 49.0s, p<0.05) in the 3D model group.
- Trend towards improved functional outcomes (p=0.14) with 3D models.
- No significant differences in operative time or estimated blood loss.
Conclusions:
- Patient-specific 3D models enhance understanding of complex anatomy.
- 3D models show potential for improving surgical outcomes in cervical foraminotomy.
- Further research may validate functional outcome improvements.

4.6K
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...

02:24Predicting Reaction Outcomes
10.4K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

01:11Anatomical Positions
19.7K
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...

01:20Anatomical Terminology
26.9K
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,...

00:51Anatomical Movements
15.5K
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,...

01:13Outcomes of Glycolysis
106.8K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...
