Noncompartmental Analysis: Mean Residence Time

594
According to statistical moment theory, mean residence time (MRT) is an important measure in pharmacokinetics. MRT can be defined as the expected mean of a probability density function distribution. It provides valuable insights into drug disposition in the body.
After the administration of a drug through intravenous bolus injection, the drug molecules are distributed throughout the body and remain there for varying periods. The MRT represents the average time these drug molecules stay in the...

Fixing Double-strand Breaks

14.4K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Double Resonance Techniques: Overview

730
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Spinal Cord01:26

Spinal Cord

1.6K
The spinal cord, a critical component of the central nervous system, extends from the base of the brainstem to the lumbar region of the vertebral column. It is essential for maintaining physical stability and facilitating communication between the brain and peripheral parts of the body.

The Spinal Cord01:54

The Spinal Cord

31.6K
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.

Summary

Orthopedic residents perceive higher competency using spinal navigation for pedicle screw placement compared to the free-hand technique. However, some residents struggle with identifying entry points, suggesting overreliance on navigation systems.

Area of Science:

  • Orthopedic Surgery
  • Surgical Navigation Technology
  • Medical Education

Background:

  • Spine surgery training now includes navigation-assisted procedures, offering new learning opportunities for residents.
  • A survey assessed orthopedic residents' perceptions and competency in pedicle screw application using spinal navigation.

Purpose of the Study:

  • To analyze orthopedic residents' perception, understanding, and competency in pedicle screw application via spinal navigation.
  • To compare spinal navigation with the free-hand technique in resident training.

Main Methods:

  • A cross-sectional descriptive survey was conducted among 20 orthopedic residents with spine rotation experience.
  • A four-part questionnaire assessed perceptions, techniques, and objective identification of pedicle screw entry points.

Main Results:

  • Residents reported higher perceived competency with spinal navigation (mean Likert score 3.65) versus free-hand (2.8).
  • All residents viewed spinal navigation as an excellent teaching tool for accuracy and critical cases.
  • 35% of residents incorrectly identified pedicle screw entry points.

Conclusions:

  • Residents perceive themselves as competent with spinal navigation for pedicle screw placement.
  • Overreliance on navigation may hinder anatomical landmark identification; focus on surface anatomy and tactile feedback is recommended.
  • Cadaveric and saw bone workshops can improve surgical anatomy understanding.
