Summary
The carrying angle of the elbow in children is significantly linked to their age, body mass index, and various body measurements. These findings highlight the relationship between physical development and elbow anatomy.
Area of Science:
- Orthopedics
- Pediatric anatomy
- Biometrics
Background:
- The carrying angle of the elbow is a clinically relevant anatomical measurement.
- Understanding factors influencing the carrying angle is important for pediatric orthopedic assessments.
Purpose of the Study:
- To investigate the correlation between morphometric measurements and the carrying angle of the human elbow in children.
- To identify anthropometric predictors of elbow carrying angle.
Main Methods:
- A prospective cohort study involving 140 children.
- Measurements included clinical carrying angle (CCA), radiological carrying angle (RCA), and various morphometric parameters (height, weight, BMI, arm/forearm length, inter-epicondylar distance).
- Statistical analysis employed unpaired t-tests and Pearson's correlation coefficient.
Main Results:
- A significant positive correlation was observed between CCA and age, weight, height, arm length, forearm length, and inter-epicondylar distance.
- A significant negative correlation was found between CCA and body mass index (BMI).
- Mean RCA and CCA values were reported for left and right elbows.
Conclusions:
- The carrying angle of the elbow in children is significantly influenced by age, BMI, and specific morphometric measurements.
- These findings contribute to understanding normal elbow development and potential deviations.

01:09Bones of the Upper Limb: Radius
2.4K
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

01:15Bones of the Upper Limb: Ulna
2.4K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

01:12Coefficient of Correlation
6.3K
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...

01:19Bones of the Upper Limb: Humerus
3.7K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

01:15Unsymmetric Bending - Angle of Neutral Axis
418
Unsymmetrical bending occurs when a structural member is subjected to bending moments in a plane that does not align with the member's principal axes. This scenario typically arises in beams and other structural components when loads are applied at non-ideal angles, introducing complexities in stress analysis.
When a bending moment is applied at an angle θ concerning the vertical axis of a symmetrical member, it can be resolved into components along the member's principal...
