Insights

Screws in the lateral masses offer a simpler, safer, and less expensive alternative to sublaminar wires for craniovertebral junction (CVJ) fusion in children, with comparable fusion rates and clinical improvement.

Area of Science:

  • Pediatric Neurosurgery
  • Spinal Surgery
  • Orthopedic Surgery

Background:

  • Craniovertebral junction (CVJ) instrumentation and fusion in children commonly utilize sublaminar wires or lateral mass screws.
  • Both sublaminar wiring and lateral mass screw techniques are considered safe for pediatric CVJ stabilization.

Purpose of the Study:

  • To compare the outcomes of sublaminar wiring versus lateral mass screw techniques for craniovertebral junction (CVJ) instrumentation and fusion in pediatric patients.
  • To evaluate the safety, efficacy, and resource utilization of two distinct surgical approaches for CVJ instability in children.

Main Methods:

  • A retrospective review of 12 pediatric patients undergoing CVJ fusion was conducted.
  • Six patients with congenital instability (Down's syndrome, Morquio's syndrome, os odontoideum) were treated with posterior wiring and fusion.
  • Six patients with iatrogenic instability (post-decompression) were treated with lateral mass screw fixation and fusion.

Main Results:

  • All 12 patients demonstrated improved clinical outcomes postoperatively, with a mean follow-up of 118.5 months.
  • Neuroradiological assessment confirmed satisfactory bony fusion and successful neural decompression in all cases.
  • The screwing technique group experienced less operative time, reduced blood loss, and decreased postoperative discomfort compared to the wiring group.

Conclusions:

  • The screwing technique for CVJ fusion in children is associated with reduced operative time, blood loss, and postoperative discomfort.
  • While requiring precise preoperative imaging, the screwing technique offers advantages in simplicity, safety (no neurovascular injury risk), and lower cost.
  • Both wiring and screwing techniques achieve satisfactory bony fusion and clinical improvement in pediatric CVJ instability.

Screw: Problem Solving

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.

Self-Locking Screw01:16

Self-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.

Frictional Forces on Screws

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.
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...

P-N junction01:11

P-N junction

A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

Magnetic Field Due to Two Straight Wires

Consider two parallel straight wires carrying a current of 10 A and 20 A in the same direction and separated by a distance of 20 cm. Calculate the magnetic field at a point "P2", midway between the wires. Also, evaluate the magnetic field when the direction of the current is reversed in the second wire.

Household Wiring And Electrical Safety01:13

Household Wiring And Electrical Safety

Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...
