Screw: Problem Solving01:21

Screw: Problem Solving

703
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...

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.

Displacement Current

Ampère's law, in its usual form, does not work in places where the current changes with time and is not steady. Thus, Maxwell suggested including an additional contribution, called the displacement current, Id, to the real conduction current I.

Position and Displacement01:31

Position and Displacement

26.2K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Frictional Forces on Screws01:17

Frictional Forces on Screws

1.6K
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...

Irritable Bowel Syndrome I: Introduction

1.0K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Summary

The lateral compression plate (LLCP) offers an effective alternative to traditional screw osteosynthesis for treating pes planovalgus. This method shows equivalent clinical outcomes with a reduced risk of hardware irritation.

Area of Science:

  • Orthopedic surgery
  • Foot and ankle reconstruction

Background:

  • Pes planovalgus, a complex foot deformity, often requires surgical intervention.
  • Traditional screw osteosynthesis (SO) is a common method for calcaneal displacement osteotomy.
  • The lateral compression plate (LLCP) offers potential advantages in implant fixation and bone integration.

Purpose of the Study:

  • To compare the clinical and radiological outcomes of the lateral compression plate (LLCP) versus screw osteosynthesis (SO) for calcaneal displacement osteotomy in patients with pes planovalgus.

Main Methods:

  • Retrospective analysis of 31 patients with stage II pes planovalgus undergoing calcaneal displacement osteotomy.
  • Patients were treated with either screw osteosynthesis (n=17) or LLCP (n=14) between 2010 and 2015.
  • Clinical outcomes assessed using ankle-hindfoot scale, Kaikkonen score, VAS, and SF-36; radiological assessment of osseous integration at 12 weeks.

Main Results:

  • Both LLCP and SO groups demonstrated significant clinical improvement.
  • No pseudarthroses were observed in either group.
  • The LLCP group had a significantly lower incidence of hardware irritation (0%) compared to the SO group (29%).
  • LLCP group showed superior results in the physical component of the SF-36.

Conclusions:

  • Surgical treatment of stage II pes planovalgus with calcaneal displacement osteotomy using LLCP is equivalent to SO.
  • LLCP demonstrates a lower incidence of hardware irritation, making it a favorable option.
