Self-Locking Screw01:16

Self-Locking Screw

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.

Decreased pulse rate01:14

Decreased pulse rate

900
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Decreasing Function01:27

Decreasing Function

284
A decreasing function describes a relationship where the output consistently declines as the input increases. This means that for any two input values, if one is greater than the other, the corresponding output is smaller. Mathematically, a function f is decreasing on an interval I if for every x1 < x2​ in I, f (x1) > f (x2). This type of behavior is visually identified on a graph that slopes downward from left to right.The nature of a function can be analyzed by calculating...

Ankle Joint01:10

Ankle Joint

2.9K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Screw: Problem Solving01:21

Screw: Problem Solving

701
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.
To evaluate the...

Decreased Body Temperature01:29

Decreased Body Temperature

1.1K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Summary
This summary is machine-generated.

Locking screws offer no significant advantage over traditional nonlocking screws for distal fibula fractures. Hardware removal rates and complications were similar, suggesting careful consideration of locking screw expense.

Area of Science:

  • Orthopaedic surgery
  • Biomechanics
  • Fracture fixation

Background:

  • Limited clinical outcome data comparing locking vs. nonlocking screws for distal fibula fractures.
  • Biomechanical studies exist, but clinical evidence is lacking.

Purpose of the Study:

  • Evaluate efficacy and complication rates of locking vs. nonlocking screws.
  • Focus on complex ankle fractures with distal fibula internal fixation.
  • Utilize 1/3 semitubular small fragment plates.

Main Methods:

  • Retrospective review of 135 patients (Jan 2010 - June 2013).
  • Analyzed internal fixation of fibula in ankle fractures using 1/3 semitubular plates.
  • Recorded patient demographics, fracture patterns, screw type, complications, and hardware removal.

Main Results:

  • No statistically significant difference in hardware removal rates (25% locking vs. 35% nonlocking).
  • No significant differences in age, BMI, diabetes, smoking, or syndesmotic screw use.
  • No significant differences in loss of fixation, infection, or surgical complications.

Conclusions:

  • Locking screws did not decrease hardware removal rates compared to nonlocking screws.
  • Hardware was equally symptomatic in both groups.
  • Routine use of locking screws for lateral malleolar fractures may not be cost-effective; consider fracture pattern.
