Anatomical Features of Individual Bones in the Upper Limb
Carpal Bones – Names, Arrangement, and Clinical Significance
The carpal bones form the wrist and play a crucial role in upper limb function. These bones provide structural support and enable complex movements.
Names of Carpal Bones
- Scaphoid
- Lunate
- Triquetrum
- Pisiform
- Trapezium
- Trapezoid
- Capitate
- Hamate
Arrangement of Carpal Bones
The carpal bones are arranged in two rows:
- Proximal Row: Scaphoid, Lunate, Triquetrum, Pisiform
- Distal Row: Trapezium, Trapezoid, Capitate, Hamate
Clinical Significance
Carpal bone fractures, particularly scaphoid fractures, are common and may lead to complications like avascular necrosis. Additionally, carpal tunnel syndrome occurs due to compression of the median nerve, leading to pain and dysfunction.
