What is a scaphoid fracture?

Scaphoid fracture is one of the most common wrist fractures.

It is usually caused by indirect violence, such as palm landing. Scaphoid plays an important role in wrist movement, and violence transmission easily leads to fracture. When palm strikes first, violence is transmitted through carpal bone to scaphoid bone, which may cause fracture of different parts. This injury mechanism is more common, especially in sports injury or accidental fall. Wrist pain, swelling, limited movement, and tenderness at snuff box are obvious. Local pain and swelling will occur after the fracture, which will affect the normal flexion, extension and rotation of the wrist joint. The snuffbox is the body surface projection area of the scaphoid bone, and tenderness here is one of the important signs for diagnosing scaphoid bone fractures. X-ray examination can initially determine the fracture condition, but it may be difficult to detect some occult fractures. At this time, CT examination can more accurately assess the specific shape and location of the fracture. Fractures without obvious displacement can be treated conservatively such as plaster fixation; Displaced or unstable fractures may require open reduction and internal fixation to promote fracture healing and restore wrist function. The blood supply of the scaphoid bone is relatively poor, and if it is not treated properly or promptly, it is easy to lead to non-union of the fracture. Long-term non-union may also lead to ischemic necrosis, which seriously affects wrist function. Early flexion and extension of the fingers can promote blood circulation and prevent muscle atrophy and joint stiffness. In

short, scaphoid fracture needs timely diagnosis and treatment, according to the specific circumstances to choose the appropriate treatment plan, and pay attention to rehabilitation training to reduce complications and promote the recovery of wrist function.
