For nondisplaced distal scaphoid fracture, what management is appropriate?

• A. Short arm cast without thumb immobilization
• B. A thumb spica cast immobilizing the thumb for 6-10 weeks
• C. Rest and activity as tolerated
• D. Surgical fixation

Answer: (B)

Nondisplaced distal scaphoid fractures heal best with immobilization that fully limits thumb and wrist motion. A thumb spica cast immobilizes both the wrist and the thumb, typically for about 6–10 weeks, to reduce movement across the scaphoid and allow true bone healing. The goal is to prevent micro-movement that can delay healing or lead to nonunion, and the distal scaphoid has relatively good healing potential when kept stable. Using a short arm cast without immobilizing the thumb leaves the fracture exposed to thumb-driven forces, which can hinder healing. Rest and activity are not enough to stabilize the fracture, and surgery is generally reserved for displaced or unstable fractures or when conservative treatment fails.
