There are two basic forms of trauma to the back: major trauma, such as a one-time event and repeated micro-trauma. The good news is that both can be avoided (at least most of the time).
Major back trauma can be avoided by proper body mechanics (every time), caution with activities (such as moving heavier objects), good technique with strenuous tasks, and a lifestyle focused on safety. PREVENTING FALLS is key!
Repeated micro-trauma can come from:
1. Poor posture over the years
2. Multiple minor back injuries
3. Limping for excessive periods of time
5. A sedentary lifestyle/lack of exercise (starting early in life)
6. Improper bending, twisting and lifting
7. Playing certain sports
