Patterns of fractures and dislocations of the pelvis are characterized by the force of blow, magnitude, and nature of adjacent soft-tissue disruption and the quality of the involved tissue. Depending on the intensity of the trauma there are different types of fracture pattern that might result.
Major Trauma
Depending on the vector and magnitude of the provocative blow, specific injury patterns are likely to ensue that involve diverse supportive elements of the pelvic ring. The injury patterns are may be
- The external rotation injuries or lateral compression injury
- Crushing injury.
Fall of a log over pelvis results in compression fractures.
Source of Violent or Major Trauma to the Pelvis are
- Motor-vehicle accident
- Sports
- Fall from height
- Crushing injury
- Gunshot and projectile related
Moderate and Minor Trauma
There is an increase in number of pelvic fractures following moderate and minor trauma. This has been attributed to rising number of patients with osteoporosis. A minor fall may result in fracture of pelvis in these patients which other wise would not been there if the bones were strong enough
In such cases the healing capacity is also dimnished.
