Scaphoid bones, or scaphoids, are small, boat-shaped bones in the human wrist. The term "scaphoid" is derived from the Greek word "skaphe," meaning boat, and "oid" meaning resembling. There are two scaphoid bones in each wrist, one on the right side and one on the left, located near the base of the thumb.
These bones play a crucial role in wrist movement and stability. They are considered part of the carpal bone group, which consists of eight bones that make up the wrist joint. The scaphoid bones connect the two rows of carpal bones, connecting the proximal row to the distal row.
Their boat-shaped structure allows for smooth gliding and movement between the proximal and distal carpal bones, enabling flexion, extension, abduction, and adduction of the wrist. Additionally, they assist in distributing forces during weight-bearing activities, such as lifting and gripping objects.
Due to their location and function, scaphoid bones are prone to fractures, often caused by a fall on an outstretched hand. Fractures of the scaphoid bone can be challenging to diagnose and treat. Delayed or inadequate treatment may lead to complications, such as impaired hand function and chronic pain. Therefore, prompt medical attention is essential in cases of suspected scaphoid fractures.
In summary, scaphoid bones are the boat-shaped bones located in the wrist, playing a critical role in wrist movement and stability. They connect the two rows of carpal bones and are susceptible to fractures, requiring proper diagnosis and treatment.
