It takes a force between 2,000 and 10,000 newtons to disrupt the adult pelvic ring, which includes the pubic bone.
The pubic bone is a part of the pelvic ring, a bony structure in the lower part of the trunk that provides support and protection for organs. The strength of this ring makes it quite resistant to breakage. Forces large enough to fracture a pubic bone are generally the result of high-impact traumas.
Forces Leading to Pubic Bone Fractures
Fractures of the pubic bone typically don't occur due to everyday activities. They are usually associated with significant external forces. Here's a breakdown of common causes:
- Traffic Accidents: The large forces involved in car crashes, motorcycle accidents, and pedestrian incidents are common causes of pelvic fractures. The impact from such accidents often transmits a great deal of force to the pelvis.
- Crush Trauma: Being trapped or crushed by heavy objects can result in extreme pressure on the pelvic area, leading to bone breakage. This is common in industrial or construction site accidents.
- Falls from Great Heights: A fall from a substantial height can generate considerable force upon impact, which may exceed the pubic bone's capacity to withstand it.
What Happens Beyond the Bone
When forces of 2,000 to 10,000 newtons or more are applied to the pelvis, it's not just the bones that are affected. The damage can extend to soft tissues and internal organs. As referenced, disruptions also occur to soft tissues inside the small pelvis and around the pelvic ring [2]. This can lead to additional complications, such as:
- Torn ligaments
- Damage to blood vessels
- Nerve injuries
- Organ damage
Summary of Forces Required
| Bone | Force Required (Newtons) | Common Causes |
|---|---|---|
| Pubic Bone (part of the Pelvic Ring) | 2,000 - 10,000 | Traffic accidents, crush traumas, falls from great heights |
In summary, it takes a substantial amount of force, typically between 2,000 and 10,000 newtons, to break a pubic bone. Such injuries usually occur due to high-impact incidents like traffic accidents or falls from great heights. Beyond the bone itself, soft tissues and organs within the pelvis are also vulnerable to damage.
