Which option is a common management for Bennet fracture?

Protecting the base of the thumb metacarpal at the CMC joint with immobilization is the typical initial approach for a Bennet fracture. A thumb spica cast holds the thumb and wrist in the correct position, preventing redisplacement and allowing the joint surfaces to heal. Surgery or fusion is reserved for cases with significant displacement, instability, or articular incongruity—situations where nonoperative immobilization won’t maintain proper alignment. Observing without immobilization risks further displacement and the development of arthritis, while wrist fusion would overly limit thumb function and isn’t the standard first-line treatment for this injury. So, immobilization in a thumb spica cast is the most common initial management.
