PHTLS Musculoskeletal Trauma 5

Question 1

A pediatric patient sustains a fracture through the growth plate of the distal tibia. Which fracture classification system specifically addresses physeal (growth plate) injuries?

Accepted Answer

Salter-Harris Classification

Answer

The Salter-Harris classification describes fractures involving the physis (growth plate) in pediatric patients, which are significant because they can affect bone growth.

Question 2

Which of the following is the MOST appropriate initial field treatment for a suspected scapular fracture?

Accepted Answer

Immobilize with a sling and swathe and monitor for respiratory compromise

Answer

Scapular fractures indicate significant force and are associated with thoracic injuries; immobilize with a sling and swathe and monitor carefully for pneumothorax or pulmonary contusion.

Question 3

When using a vacuum splint for an ankle fracture-dislocation, what is the PRIMARY advantage over rigid splints in the prehospital environment?

Accepted Answer

Conforms to irregular deformities and reduces pressure points

Answer

Vacuum splints conform to the shape of the deformed extremity, providing comfortable immobilization while distributing pressure evenly and reducing pressure point injury.

Question 4

A patient involved in a high-energy MVC has a suspected calcaneus (heel bone) fracture. What associated injury should be specifically evaluated based on the mechanism?

Accepted Answer

Lumbar vertebral compression fractures

Answer

Calcaneus fractures from axial loading (falls or foot-well intrusion) are associated with lumbar spine compression fractures due to transmission of forces up the extremity.

Question 5

Which of the following BEST describes the PHTLS principle for managing an extremity fracture in a critical trauma patient with airway compromise and suspected internal hemorrhage?

Accepted Answer

Rapidly splint fractures only if time permits after life threats are controlled

Answer

PHTLS follows the principle that life threats (airway, breathing, circulation) are addressed before limb threats; fracture splinting is performed only after life-threatening problems are controlled or concurrently en route when feasible.
