PURPOSE: To review bicycle and motorcycle wheel spoke injuries around the foot and ankle in 24 children.
METHODS: Medical records of 12 boys and 12 girls aged 2 to 11 (mean, 5.3) years who presented with an isolated posterior heel injury caused by wheel spokes of a motorcycle (n=9) or bicycle (n=15) were reviewed.
RESULTS: All 9 motorcycle injury patients and 8 of 15 bicycle injury patients had lacerations. The remaining 7 bicycle injury patients had abrasions and developed skin necrosis and ulcerations, with 5 requiring debridement. The most common site of laceration was the posterolateral heel; 7 of these patients had deep soft tissue injury, and in 5 the Achilles tendon was partially cut or completely severed. The mean number of operations was 2.2 in the motorcycle group and 1.3 in the bicycle group. Seven patients with severe skin loss required skin grafting or flap surgery for wound coverage. The mean time from injury to definitive treatment was 8.2 days. The mean length of hospital stay was 18.4 days in the motorcycle group and 8.1 days in the bicycle group. Delayed definitive treatment was associated with more operations (r=0.499, p=0.013) and longer hospital stay (r=0.567, p=0.004).
CONCLUSION: Wheel spoke injuries may result in severe soft tissue damage and bony trauma. Poor prognostic factors included high-energy injury, contamination and infection, and delayed treatment.
