Summary
Carpal bone volume increases with age in both men and women, independent of osteoarthritis. This finding is consistent across all carpal bones, suggesting a natural aging process affecting bone size.
Area of Science:
- Orthopedics
- Radiology
- Gerontology
Background:
- Clinical recognition of carpal bone volume changes is vital for predicting osteoarthritis (OA).
- Understanding age-related carpal bone volume differences across genders is crucial.
- Computed tomography (CT) wrist scans and 3D surface models were utilized.
Purpose of the Study:
- To explore age-related differences in carpal bone volumes across genders.
- To leverage CT scans for 3D carpal bone model creation.
- To investigate the relationship between age, gender, and carpal bone volume.
Main Methods:
- 181 patients' CT wrist scans were analyzed using 3D Slicer software.
- Carpal bone volumes were calculated for scaphoid, lunate, triquetrum, pisiform, hamate, capitate, and trapezium.
- Statistical analysis included Spearman correlation and Interclass Correlation Coefficient (ICC).
Main Results:
- A significant positive correlation was found between age and the volume of all carpal bones (rho = 0.37-0.611, P < .05).
- This correlation was consistent across genders.
- High intrauser and interuser reliability (ICC = 0.86-0.95) was confirmed for specific bone volume measurements.
Conclusions:
- Carpal bone volume increases with age, potentially independent of osteoarthritis.
- Trapezial volume increases may be linked to OA and osteophyte formation, particularly in older women.
- Age-related carpal bone volume increase is a consistent finding across genders and carpal bones.

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...

01:17Gross Anatomy of Bone
5.1K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

5.4K
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...

01:29Bone Disorders
3.5K
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...

01:19Bones of the Upper Limb: Humerus
3.2K
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...

2.2K
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...
