Changes in the Appendicular Skeleton with Age

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Classification of Bones

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Growth of Cartilage and Bone Tissue

Growth of Cartilage and Bone Tissue

Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Summary

Skeletal maturity indicators like the Cervical Vertebrae Maturity Index (CVMI) and modified MP3 methods provide a more accurate estimation of maturation than chronological age. Both methods showed a positive correlation with chronological age in subjects aged 9-16.

Area of Science:

Orthodontics
Pediatric Dentistry
Radiology

Background:

Chronological age is an imprecise measure of an individual's maturational status.
Skeletal maturity indicators offer a more reliable assessment of developmental stage.
Accurate skeletal age determination is crucial for treatment planning in orthodontics and pediatric dentistry.

Purpose of the Study:

To investigate the correlation between chronological age and skeletal age.
To evaluate the efficacy of the Cervical Vertebrae Maturity Index (CVMI) and modified MP3 methods in assessing skeletal maturity.

Main Methods:

Study included 39 subjects aged 9-16 years.
Lateral cephalograms and hand-wrist radiographs were analyzed.
Skeletal age was assessed using the CVMI and modified MP3 methods; data analyzed with SPSS using Kendall's Tau and linear regression tests.

Main Results:

A statistically significant positive correlation was observed between chronological age and skeletal age assessed by the CVMI method (r=0.398).
A significant positive correlation was also found between chronological age and skeletal age assessed by the modified MP3 method (r=0.382).
P values were greater than 0.003, indicating statistical significance.

Conclusions:

Both CVMI and modified MP3 methods demonstrate a positive correlation with chronological age.
These skeletal maturity indicators provide a more accurate estimation of maturational status compared to chronological age alone.
Findings support the use of CVMI and modified MP3 for assessing skeletal maturity in adolescents.
