How these injuries happen

Most injuries involving natural surfaces occur during your routine movement across uneven terrain. Falls on the same level account for 85% of all reported incidents, often triggered by loose gravel, damp grass, or unexpected slopes. When you traverse embankments or rocky ledges, the risk of losing your balance increases, frequently leading to high-impact falls that cause severe bone fractures.
