Scaphoid

Scaphoid fractures usually result from a fall on an outstretched hand (FOOSH) and are common in young adults. Tenderness in the anatomical snuffbox is a key clinical sign.
Plain radiographs may initially appear normal—MRI or CT can aid early diagnosis.
Fractures are classified by location (waist, proximal pole, distal pole) and displacement.
Non-displaced fractures can often be managed with cast immobilization; displaced or proximal fractures frequently require surgical fixation.
Delayed diagnosis increases the risk of complications such as nonunion and avascular necrosis (AVN).
