Summary
This study introduces a novel technique for precise pedicle screw placement in spine surgery. The method utilizes a simple instrument to angulate screws, potentially reducing fluoroscopy time and radiation exposure.
Area of Science:
- Orthopedic Surgery
- Spine Surgery
- Surgical Techniques
Background:
- Pedicle screw instrumentation is a common practice in spine surgery.
- Accurate placement requires intraoperative imaging, typically fluoroscopy in two planes.
- Current methods lead to increased operative time and radiation exposure.
Purpose of the Study:
- To present a simple technique for angulating pedicle screws in the cephalocaudal direction.
- To reduce reliance on image intensification during pedicle screw placement.
- To potentially decrease operative time and radiation exposure in spine surgery.
Main Methods:
- A novel surgical pearl technique is described.
- Utilizes readily available instruments on the operating table.
- Aims to guide pedicle screw angulation without multiple imaging planes.
Main Results:
- The technique facilitates cephalocaudal angulation of pedicle screws.
- Potential for reduced intraoperative fluoroscopy usage.
- May expedite the overall surgical procedure.
Conclusions:
- This simple instrument-based technique offers an alternative for pedicle screw angulation.
- It may improve efficiency and reduce radiation exposure in spine surgery.
- Further studies could validate its widespread applicability and impact.

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.

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.

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.

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Brick-cutting techniques involve various tools and methods to shape bricks for construction. A mason's hammer with a chisel-pointed end is used for basic shaping through sharp, precise strikes. For more complex shapes requiring higher precision, a power saw with a water-cooled diamond blade is used.
Cut bricks are categorized by size. Bricks cut to half their original length are called half-bats, while those cut to three-fourths their length are known as three-fourth bats.
