Summary
Aging significantly impacts distal radius dimensions, specifically ulnar variance, showing a trend toward less negative values until skeletal maturity. These radiographic changes are independent of sex.
Area of Science:
- Orthopedics
- Radiology
- Human Anatomy
Background:
- Distal radius radiographic parameters change with aging.
- Understanding these age-related changes is crucial for interpreting wrist X-rays.
Purpose of the Study:
- To investigate serial changes in distal radius radiographic parameters due to aging.
- To compare these parameters across different age groups and sexes.
Main Methods:
- Prospective study of 120 healthy individuals across four age groups.
- Wrist radiography performed to measure distal radius parameters.
- Analysis focused on ulnar variance (UV), radial inclination (RI), palmar tilt (PT), and radial length (RL).
Main Results:
- Ulnar variance showed a significant shift towards less negative values between individuals under 20 and those over 20 years old.
- No significant differences in UV were found within the below-20 or above-20 age groups.
- No significant sex-based differences were observed in any measured parameters.
Conclusions:
- Significant changes in ulnar variance occur with aging, progressing towards less negative values until skeletal maturity.
- These age-related radiographic alterations are not sex-dependent.

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...

01:29Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:09Bones of the Upper Limb: Radius
10.9K
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.
The radius has a nail-shaped head, and a...

01:19The Effect of Aging on Tissues
4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:15Bones of the Upper Limb: Ulna
10.6K
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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
316
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
