Question

fracture to which part of scaphoid can be most dangerous if undetected?
a) proximal
b) middle
c) distal
d) all segments are equally dangerous

Explanation:

The scaphoid bone has a blood supply that enters from the distal end. A proximal fracture can disrupt the blood supply to the proximal fragment, leading to avascular necrosis (bone death due to lack of blood supply). This is a serious complication. The middle and distal fractures have a better blood supply compared to the proximal part. So, a proximal scaphoid fracture is most dangerous if undetected.

Answer:

a) Proximal
