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 ...
Direct blow on back of upper forearm would be a very uncommon cause. In this context, isolated ulnar shaft fractures are most commonly seen in defence against blunt trauma (e.g. nightstick injury). Such an isolated ulnar shaft fracture is not a Monteggia fracture. [citation needed] It is called a 'nightstick fracture'.

In the event of inordinate application of force over the wrist, this small scaphoid is likely to be the weak link [citation needed]. Scaphoid fracture is one of the most frequent causes of medico-legal issues. An anatomical anomaly in the vascular supply to the scaphoid is the area to which the blood supply is first delivered.
(b) Initial "scaphoid" view was negative. (c) Followup anteroposterior radiographs, 12 days later, shows obvious scaphoid fracture (arrows). [1] Triquetral fracture usually occurs on the dorsal aspect by impingement from the ulnar styloid or avulsion of strong ligamentous attachment.
Scapholunate advanced collapse is the most common form, followed by scaphoid non-union advanced collapse (SNAC). [3] Other post-traumatic causes such as intra-articular fractures of the distal radius or ulna can also lead to wrist osteoarthritis, but are less common.
The scapholunate ligament is an intraarticular ligament binding the scaphoid and lunate bones of the wrist together. It is divided into three areas, dorsal, proximal and palmar, with the dorsal segment being the strongest part. [3] It is the main stabilizer of the scaphoid. In contrast to the scapholunate ligament, the lunotriquetral ligament ...
