[1] Symptoms generally includes pain at the base of the thumb which is worse with use of the hand.
[2] Complications may include nonunion of the fracture, avascular necrosis of the proximal part of the bone, and arthritis.
[2] In such cases the affected area may be immobilised in a splint or cast and reviewed with repeat X-rays in two weeks, or alternatively an MRI or bone scan may be performed.
This blood supply is tenuous, increasing the risk of nonunion, particularly with fractures at the wrist and proximal end.
[4] If not treated correctly non-union of the scaphoid fracture can lead to wrist osteoarthritis.
[6] Fractures of scaphoid can occur either with direct axial compression or with hyperextension of the wrist, such as a fall on the palm on an outstretched hand.
Scaphoid fractures are often diagnosed using plain radiographs and multiple views are obtained as standard.
[10] Therefore, people with tenderness over the scaphoid (those who exhibit pain to pressure in the anatomic snuff box ) are often splinted in a thumb spica for 7–10 days at which point a second set of X-rays is taken.
[7][8] The scaphoid receives its blood supply primarily from lateral and distal branches of the radial artery.
[citation needed] Percutaneous screw fixation is recommended over an open surgical approach when it is possible to achieve acceptable bone alignment closed as minimal incisions can preserves the palmar ligament complex and local vasculature, and help avoid soft tissue complications.
Internal fixation can be done dorsally with a percutaneous incision and arthroscopic assistance [17] or via a minimal open dorsal approach,[18] or via a volar approach in which case slight excavation of the edge of the trapezium bone may be necessary to reach the scaphoid as 80% of this bone is covered with articular cartilage, which makes it difficult to gain access to the scaphoid.
[22] They are less common in children and older adults because the distal radius is weaker contributor to the wrist and more likely to fracture in these age groups.
