Summary
Inserting pedicle screws into cement-augmented vertebrae is now simpler and safer. This technique addresses challenges in spinal instrumentation for patients with osteoporotic vertebral compression fractures (OVCF).
Area of Science:
- Orthopedics
- Neurosurgery
- Spinal Surgery
Background:
- Osteoporotic vertebral compression fractures (OVCF) are increasing with an aging population.
- Cement augmentation is common for OVCF, leading to more patients needing spinal instrumentation.
- Pedicle screw insertion into cement-augmented vertebrae presents technical difficulties.
Purpose of the Study:
- To present a straightforward and repeatable method for safely inserting pedicle screws into cement-augmented vertebral bodies.
- To overcome the technical challenges associated with this procedure.
Main Methods:
- A novel technique was developed and applied to ten patients.
- These patients had prior cement augmentation for OVCF and required posterior spinal instrumentation.
- The technique focused on safe and effective pedicle screw placement.
Main Results:
- Pedicle screws were successfully inserted into all cement-augmented vertebrae across ten patients.
- No intraoperative complications occurred, such as drill breakage, cement dislodgement, or anterior wall breaches.
- The technique proved safe and reliable in practice.
Conclusions:
- Pedicle screw insertion into cement-augmented vertebrae can be achieved safely and reliably.
- This technique simplifies a previously complex surgical procedure.
- It offers a viable solution for spinal instrumentation in patients with augmented vertebrae.

01:24Hydration of Cement
960
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...

01:17Soundness of Cement
586
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create...

01:21Screw: Problem Solving
709
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.

2.5K
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.

01:21Portland Cement
736
Portland cement is the essential binding ingredient in concrete, made from finely ground materials including lime, iron, silica, and alumina. Lime is derived primarily from limestone, marble, marl, seashells, and clays, which also supply iron and alumina, while silica is sourced from sand, chalk, and bauxite. Contemporary manufacturing of Portland cement is a significant source of carbon dioxide emissions, prompting research into reducing its content in concrete through alternative...

01:15Fineness of Cement
527
The fineness of cement directly influences the rate of hydration, as the hydration begins at the surface of the cement particles. In addition to hydration, the fineness of cement is vital for various properties of concrete including workability, gypsum requirement, and long-term behavior. The fineness of cement is represented in terms of the specific surface of cement which is typically measured in square meters per kilogram, with several methods available for this determination.
