Radiology Case Reports
|August 8, 2019
Summary
Vascular injury from clavicle screw fixation is rare. Careful screw selection based on imaging is crucial to avoid iatrogenic complications during clavicle osteosynthesis.
Area of Science:
- Orthopedic Surgery
- Vascular Surgery
- Radiology
Background:
- Clavicle osteosynthesis is a common procedure for fracture repair.
- Vascular injury is a rare but serious complication associated with clavicle fracture fixation.
- Preoperative imaging and anatomical knowledge guide safe screw selection.
Observation:
- A 27-year-old female experienced iatrogenic vascular injury after clavicle plate and screw fixation.
- The injury was attributed to an improperly selected screw during the osteosynthesis procedure.
- The patient required subsequent endovascular repair and revision orthopedic surgery.
Findings:
- This case highlights a rare complication of clavicle osteosynthesis.
- Iatrogenic vascular injury resulted from screw misplacement.
- Appropriate screw length selection is critical to prevent neurovascular damage.
Implications:
- Emphasizes the importance of meticulous surgical technique in clavicle osteosynthesis.
- Highlights the need for precise screw length selection guided by preoperative imaging.
- Underscores the potential for severe vascular complications from seemingly minor errors in orthopedic fixation.

01:16Self-Locking Screw
2.4K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

01:21Screw: Problem Solving
688
In mechanical engineering, the interaction between a threaded screw shaft and a plate gear involves analyzing the resisting torque on the plate gear that can be overpowered when a specific torsional moment is applied to the shaft. To better comprehend this concept, consider a generic situation with a threaded screw shaft with a given mean radius and lead and a plate gear with a specified mean radius. The coefficient of static friction between the screw and gear is also provided.

Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

6.3K
Arteries, the vasculature responsible for transporting blood from the heart, possess robust walls capable of enduring the elevated pressures exerted by the heartbeat. Arteries near the heart are especially thick-walled and enriched with elastic fibers across their three tunics, classifying them as elastic or conducting arteries. These arteries, usually with a diameter exceeding 10 mm, are characterized by their ability to dilate in response to the blood pumped from the heart's ventricles...
