Wrist fractures occur in approximately 25-30% of all bicycle accidents involving falls or collisions. When cyclists are struck by vehicles or forced to swerve suddenly, the natural reflex is to extend the arms to break the fall. This protective instinct often results in the full force of impact being absorbed by the wrists, causing [fractures to the radius, ulna, or small carpal bones](/broken-bones-fractures).
The most common wrist fractures in bicycle accidents include distal radius fractures (Colles' fractures), scaphoid fractures, and ulnar styloid fractures. These injuries range from simple, stable fractures that may heal with casting to complex, comminuted fractures requiring surgical intervention with plates, screws, or external fixation devices. Recovery times vary from 6-8 weeks for simple fractures to 6-12 months for severe injuries requiring multiple surgeries.
Many cyclists don't realize the full extent of their wrist injury immediately after an accident. Adrenaline can mask pain, and some fractures—particularly scaphoid fractures—may not show up clearly on initial X-rays. This is why it's critical to seek comprehensive medical evaluation after any [bicycle accident](/bicycle-accidents), even if you think your injuries are minor. Delayed diagnosis of wrist fractures can lead to complications like avascular necrosis, nonunion, and permanent disability.
