One-Degree-of-Freedom System01:24

One-Degree-of-Freedom System

In mechanical engineering, one-degree-of-freedom systems form the basis of a wide range of electrical and mechanical components. Using these models, engineers can predict the behavior of various parts in a larger system, which gives them insight into how different forces interact with each other.
A one-degree-of-freedom system is defined by an independent variable that determines its state and behavior. One example of a one-degree-of-freedom system is a simple harmonic oscillator, such as a...
Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis
An immobile...

Two-Dimensional Force System

A two-dimensional system in mechanical engineering involves the analysis of motion and forces in a plane. A two-dimensional force vector can be resolved into its components as:
Sympathetic Pathways: Sympathetic Chain Ganglia01:20

Sympathetic Pathways: Sympathetic Chain Ganglia

The sympathetic chain ganglia, also known as the sympathetic trunk ganglia or paravertebral ganglia, are a series of ganglia located bilaterally on either side of the spinal column. These ganglia serve as relay stations for the sympathetic nervous system. Preganglionic neurons originating in the spinal cord project their axons to the sympathetic chain ganglia. Within the ganglia, these preganglionic fibers synapse with postganglionic neurons.The postganglionic neurons of the sympathetic trunk...
Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
Three-Dimensional Force System01:30

Three-Dimensional Force System

In mechanical engineering, a three-dimensional force system is a system of forces acting in three dimensions, with forces applied along the x, y, and z coordinate axes. The three-dimensional force system is an important concept in mechanical engineering, as it allows engineers to understand and analyze the behavior of objects and structures in three dimensions. By understanding the forces acting on a system, engineers can design more efficient and effective mechanical systems that can withstand...

Summary
This summary is machine-generated.

The Dynesys Dynamic Stabilization system offers effective polysegmental spinal stabilization, improving walking ability in patients with spinal pathology. While generally safe, it may not correct severe spinal deformities.

Area of Science:

  • Spine surgery
  • Orthopedic technology

Background:

  • The Dynesys System is designed for polysegmental dorsal spinal stabilization, aiming to preserve spinal motion.
  • Claims suggest it provides sufficient stabilization for multiple spinal segments.

Purpose of the Study:

  • To evaluate the efficacy and safety of the Dynesys Dynamic Stabilization system in patients with polysegmental spinal pathology.
  • To assess functional outcomes and complications associated with the system.

Main Methods:

  • A prospective study involving 20 treatment-naïve patients with polysegmental spinal pathology.
  • Patients underwent polysegmental decompression and stabilization with the Dynesys system.
  • Preoperative bone density was measured, and patients were followed for an average of 11.8 months.

Main Results:

  • Significant improvement in walking ability, from 581.5 m to 1640.0 m post-surgery.
  • Low complication rate, including one dural tear and one hypertensive crisis.
  • One case of implant loosening required revision surgery with dorso-ventral fusion.

Conclusions:

  • The Dynesys Dynamic Stabilization system is a viable treatment option for polysegmental spinal pathology.
  • The system's limitations include an inability to correct extensive spinal malalignments or deformities.
