The scaphoid can be slow to heal because of the limited circulation to the bone. Fractures of the scaphoid must be recognized and treated quickly, as prompt treatment by immobilization or surgical fixation increases the likelihood of the bone healing in anatomic alignment, thus avoiding mal-union or non-union. [6] Delays may compromise healing.
A scaphoid fracture is a break of the scaphoid bone in the wrist. [1] Symptoms generally includes pain at the base of the thumb which is worse with use of the hand. [2] The anatomic snuffbox is generally tender and swelling may occur. [2] Complications may include nonunion of the fracture, avascular necrosis of the proximal part of the bone ...
In a case where there is localized tenderness within the snuffbox, knowledge of wrist anatomy leads to the speedy conclusion that the fracture is likely to be of the scaphoid. This is understandable as the scaphoid is a small, oddly shaped bone whose purpose is to facilitate mobility rather than confer stability to the wrist joint [citation ...

The term navicular bone or hand navicular bone was formerly used for the scaphoid bone, [1] one of the carpal bones of the wrist. The navicular bone in humans is located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid.
Radial scaphoid column: scaphoid, trapezium, and trapezoid; Lunate column: lunate and capitate; Ulnar triquetral column: triquetrum and hamate; In this context the pisiform is regarded as a sesamoid bone embedded in the tendon of the flexor carpi ulnaris. [4]
Breakage of the radius at the radial styloid is known as a Chauffeur's fracture; it is typically caused by compression of the scaphoid bone of the hand against the styloid. De Quervain syndrome causes pain over the styloid process of the radius.
Chauffeur's fracture, also known as Hutchinson fracture, is a type of intraarticular oblique fracture of the radial styloid process in the forearm. [1] The injury is typically caused by compression of the scaphoid bone of the hand against the styloid process of the distal radius. It can be caused by falling onto an outstretched hand.
