Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
General Structure of a Vertebra01:30

General Structure of a Vertebra

A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.

Summary
This summary is machine-generated.

The cervical vertebrae maturation (CVM) method for predicting mandibular growth shows poor reproducibility. Clinicians demonstrated low agreement in staging, questioning its reliability for orthodontic treatment timing.

Area of Science:

  • Orthodontics
  • Dental Radiology
  • Growth and Development

Background:

  • Cervical vertebrae maturation (CVM) is used to predict peak mandibular growth.
  • The method's reliability is questioned due to potential methodologic flaws.

Purpose of the Study:

  • To rigorously evaluate the reproducibility of cervical vertebrae maturation (CVM) staging.
  • To assess interobserver and intraobserver reliability using a stringent methodology.

Main Methods:

  • Ten orthodontists assessed CVM stages on 30 individual and 30 paired cephalometric radiographs across two sessions.
  • Interobserver and intraobserver reliability were analyzed using Kendall's W and weighted kappa statistics.

Main Results:

  • Interobserver agreement for CVM staging was below 50% among the orthodontists.
  • Intraobserver agreement averaged only 62%, indicating limited consistency.
  • Agreement improved slightly with longitudinal radiographs but remained moderate.

Conclusions:

  • The CVM method exhibits insufficient reproducibility for reliable clinical application.
  • The study advises against using CVM as a strict guideline for orthodontic treatment timing.
