Orthopedic Trauma: Blunt Trauma Injuries

Study Notes

Blunt Trauma

Orthopedic Trauma

Results from direct blows or indirect forces that cause injury to the musculoskeletal system
Common injuries:
- Fractures (long bone, pelvis, spine)
- Dislocations (joint instability)
- Soft tissue injuries (muscle, tendon, ligament)
Mechanisms of injury:
- Direct blow (e.g., fall onto an outstretched hand)
- Indirect force (e.g., twisting or bending)
Diagnosis:
- Physical examination
- Imaging studies (X-ray, CT, MRI)
Management:
- Immobilization (casting, splinting)
- Pain management
- Surgical intervention (reduction, fixation)

Chest Trauma

Results from blunt force to the chest, causing injury to the thoracic cage and internal organs
Common injuries:
- Rib fractures
- Hemothorax (bleeding in the chest cavity)
- Pneumothorax (collapsed lung)
- Cardiac contusions
Mechanisms of injury:
- Direct blow (e.g., steering wheel injury)
- Deceleration forces (e.g., motor vehicle crash)
Diagnosis:
- Physical examination
- Imaging studies (chest X-ray, CT)
Management:
- Pain management
- Respiratory support (oxygen therapy, ventilatory support)
- Surgical intervention (thoracostomy, thoracotomy)

Abdominal Trauma

Results from blunt force to the abdomen, causing injury to internal organs
Common injuries:
- Liver lacerations
- Spleen injuries
- Kidney injuries
- Intestinal perforations
Mechanisms of injury:
- Direct blow (e.g., assault)
- Deceleration forces (e.g., motor vehicle crash)
Diagnosis:
- Physical examination
- Imaging studies (abdominal CT, ultrasound)
Management:
- Fluid resuscitation
- Pain management
- Surgical intervention (laparotomy, angiography)

Head Trauma

Results from blunt force to the head, causing injury to the brain and surrounding structures
Common injuries:
- Concussions
- Intracranial hemorrhages
- Skull fractures
- Cerebral edema
Mechanisms of injury:
- Direct blow (e.g., fall)
- Deceleration forces (e.g., motor vehicle crash)
Diagnosis:
- Physical examination
- Imaging studies (head CT, MRI)
Management:
- Neurological monitoring
- Pain management
- Surgical intervention (craniotomy, evacuation of hematoma)
