Summary
A new polyaxial screw rod technique using C1 lateral mass and C1-C2 screws effectively immobilizes the C1-C2 segment for atlantoaxial instability, showing no complications and improved neck pain.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Fusion Techniques
Background:
- Atlantoaxial instability requires effective surgical treatment.
- Established methods include Magerl and Harms/Goel C1-C2 screw rod techniques.
- A novel technique using polyaxial screws with C1 lateral mass and C1-C2 transarticular fixation is presented.
Purpose of the Study:
- To evaluate the efficacy and safety of a novel polyaxial screw rod fixation technique for atlantoaxial instability.
- To assess the rate of complications and patient outcomes.
Main Methods:
- Retrospective review of 14 patients with various C1-C2 instability causes.
- Surgical techniques included posterior C1-C2 fixation, C1-C4 fixation (osteoporosis), and C1-Th1 fixation.
- Mean follow-up was 22 months.
Main Results:
- No intraoperative complications such as vertebral artery or neural injury.
- Postoperative imaging revealed no screw malpositioning, loosening, or bone absorption.
- All patients reported improvement in neck pain.
Conclusions:
- C1 lateral mass and C1-C2 transarticular polyaxial screw rod fixation provides effective and immediate rigid immobilization.
- This technique is a safe and viable option for treating C1-C2 motion segment instability.

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...

Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments. Working near an open flame or within a laminar flow hood reduces the risk...

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.

OverviewStaining techniques in microscopy enhance the visualization of microorganisms by increasing contrast and allowing the differentiation of cellular structures. Simple staining is one of the fundamental methods used to observe the basic morphological characteristics of microorganisms, including their size, shape, and arrangement. This method relies on the application of a single dye to stain the entire cell, producing a clear contrast between the cell and the background.FixationFixation is...
