[Bicycle spoke injuries about 30 cases]

This study reports the author's 5 year experience with treating lower extremity injuries in bicycle passengers caused by the spokes. A total of 30 patients were treated during the study. Patiets ranged from 2 to 15 years old with a mean age of 6 years. The authors treated more female passengers then male passengers. The right foot was involved mote often then was the left. The achilles tendon was the most common site of injury [50 percent], wounds was classified in 4 stages. The defects exposure achille tendon was covered with distally based sural flap in 6 reports, 3 patients required skin grafting. Since the first report of bicycle spoke injuries a half century ago, prevention has not improved
