Fractures: Bone Repair01:27

Fractures: Bone Repair

6.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Frictional Forces on Screws

1.7K
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...

Self-Locking Screw01:16

Self-Locking Screw

2.7K
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.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Biomedical Engineering

Background:

  • Hoffa fractures involve uni- or bicondylar fractures of the distal femur in a coronal plane.
  • Traditional fixation methods can be complex or cause articular surface damage.

Purpose of the Study:

  • To describe a novel surgical technique for treating displaced Hoffa fractures.
  • To evaluate the efficacy of posterior-to-anterior headless compression screw fixation.

Main Methods:

  • Open reduction and internal fixation of a displaced lateral femoral condyle Hoffa fracture.
  • Utilized two headless compression screws inserted in a posterior-to-anterior direction.

Main Results:

  • Successful radiographic union of the fracture at 1-year follow-up.
  • Patient achieved a pain-free state with a knee range of motion from 0° to 100°.

Conclusions:

  • The described posterior-to-anterior screw fixation technique provides stable and physiologically less invasive treatment for Hoffa fractures.
  • This method minimizes articular surface damage compared to traditional approaches.
