Summary
Volar percutaneous screw fixation effectively treats scaphoid nonunions, achieving high union rates and excellent patient outcomes. This minimally invasive approach offers a promising solution for complex wrist fractures.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Percutaneous screw fixation is a standard treatment for acute scaphoid fractures.
- Scaphoid nonunions present a significant challenge in orthopedic practice.
- Volar percutaneous screw fixation is an alternative surgical technique.
Purpose of the Study:
- To evaluate the efficacy of volar percutaneous screw fixation for scaphoid nonunions.
- To report clinical and radiological outcomes in patients treated with this method.
Main Methods:
- Retrospective evaluation of 12 patients with scaphoid nonunion (≥13 weeks).
- Volar percutaneous fixation using a headless cannulated screw under fluoroscopic guidance.
- Clinical assessment using the modified Mayo Wrist Scoring System (MMWS).
Main Results:
- Successful union achieved in 11 out of 12 patients (91.6%).
- Mean time to union was 15.5 weeks.
- 8 patients had excellent and 3 had good outcomes based on MMWS.
Conclusions:
- Volar percutaneous screw fixation demonstrates satisfactory results for scaphoid nonunions.
- The technique offers high union rates and low complication rates.
- It is a viable option for select patients with scaphoid nonunions.

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.

01:16Self-Locking Screw

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.

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...

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.
