Summary
A modified explantation technique for the PediatrOS™ FlexTack™ implant significantly reduced complications, enabling safe removal in most cases. This improved method prevents bone and soft tissue damage during implant removal after growth guidance.
Area of Science:
- Pediatric Orthopedics
- Surgical Innovation
- Biomedical Engineering
Background:
- The PediatrOS™ FlexTack™ implant is used for limb length discrepancy correction in pediatric patients.
- Standard explantation procedures can lead to complications, including bone and soft tissue damage.
- There is a need for improved explantation techniques to ensure patient safety and minimize iatrogenic injury.
Purpose of the Study:
- To present the implantation technique of the PediatrOS™ FlexTack™ for growth guidance.
- To describe a modified explantation procedure designed to facilitate removal and prevent complications.
- To evaluate the efficacy and safety of the modified explantation technique.
Main Methods:
- Implantation involved precise K-wire placement and implant setting guided by fluoroscopy.
- The modified explantation technique included cutting the bridging part, bending implant ends, and using specialized instruments for bone dissection and extraction.
- Postoperative management for both implantation and explantation involved full weight-bearing with regular radiographic follow-up.
Main Results:
- The original explantation method resulted in a 21.9% complication rate (14 of 64 implants).
- The modified explantation procedure was applied to 70.3% of cases (45 implants).
- The modified technique achieved complete implant removal without further complications in the observed cases.
Conclusions:
- The modified explantation technique for the PediatrOS™ FlexTack™ implant is effective in preventing bone and soft tissue damage.
- This technique significantly reduces the complication rate associated with implant removal.
- The modified procedure offers a safer and more efficient option for explanting the PediatrOS™ FlexTack™ implant.

17.3K
When two or more atoms come together to form a molecule, their atomic orbitals combine and molecular orbitals of distinct energies result. In a solid, there are a large number of atoms, and therefore a large number of atomic orbitals that may be combined into molecular orbitals. These groups of molecular orbitals are so closely placed together to form continuous regions of energies, known as the bands.
The energy difference between these bands is known as the band gap.

01:10Tension
13.9K
Tension is a force along the length of a medium, in particular, a force carried by a flexible medium, such as a rope or cable. The word "tension" comes from Latin, meaning "to stretch". Not coincidentally, the flexible cords that carry muscle forces to other parts of the body are called tendons. Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pull only parallel to its length; so, a force carried by a flexible connector is a tension with a...

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

01:01Energy Bands in Solids
2.0K
Isolated atoms have discrete energy levels that are well described by the Bohr model. And, it quantifies the energy of an electron in a hydrogen atom as En. Higher quantum numbers 'n' yield less negative, closer electron energy levels.
Band Formation:
When atoms are brought close together, as in a solid, these discrete energy levels begin to split due to the overlap of electron orbitals from adjacent atoms. This split occurs because of the Pauli exclusion principle, which states...

01:22Surface Tension of Fluid
1.6K
Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.

01:26Tension Response at Adherens Junctions
3.6K
The adherens junctions that anchor cells together are multi-protein complexes that dynamically adapt to mechanical stimuli such as tensile forces and shear stress. Mechanosensory proteins in these junctions can sense such mechanical stimuli and undergo a shift in their conformation, resulting in an altered function — a process called mechanotransduction.
