PHTLS - Prehospital Trauma Life Support Musculoskeletal Trauma Questions and Answers

Question 1

A 46-year-old pedestrian was struck by a vehicle and presents with instability and crepitus on gentle palpation of the pelvis. The patient is tachycardic and hypotensive. What is the MOST critical prehospital intervention for managing this patient's suspected injury?

Accepted Answer

Application of a commercial pelvic binder or improvised sheet sling.

Answer

An unstable pelvic fracture can lead to life-threatening internal hemorrhage by increasing the volume of the pelvic cavity and causing bleeding from fractured bone surfaces and pelvic vasculature. Applying a pelvic binder is the primary intervention to stabilize the fracture, reduce pelvic volume, and help tamponade the bleeding. [10, 23]

Question 2

Which of the following is considered the most reliable and earliest sign of developing compartment syndrome in a conscious patient with a closed tibial fracture?

Accepted Answer

Pain that is out of proportion to the injury and unrelieved by standard measures.

Answer

The earliest and most significant finding of acute compartment syndrome is severe pain that is disproportionate to the physical findings of the injury. [16, 17, 20] This pain is often described as deep, burning, and is not relieved by immobilization or typical doses of analgesics. The other classic signs, such as pallor, pulselessness, and paresthesia, are typically later and more ominous findings. [16]

Question 3

A 24-year-old has an obviously deformed, closed fracture of the right forearm after a fall. According to PHTLS principles, which assessment is mandatory immediately before AND after applying a rigid splint?

Accepted Answer

Pulse, motor function, and sensation (PMS) distal to the injury.

Answer

Assessing distal pulse, motor function, and sensation (PMS), also known as CSM, is critical both before and after splinting any extremity fracture. [1, 24] The 'before' assessment establishes a baseline, and the 'after' assessment ensures that the splint has not compromised neurovascular function to the limb.

Question 4

Application of a traction splint is indicated for an isolated, mid-shaft femur fracture. In which of the following situations is a traction splint contraindicated?

Accepted Answer

The patient also has a suspected fracture of the ipsilateral tibia.

Answer

A traction splint is contraindicated if there is a suspected fracture to the pelvis, hip, knee, tibia, or fibula on the same side as the femur fracture. [1, 7, 8] The splint applies force against the ankle and the pelvis/hip; a fracture in the lower leg would prevent the effective application of traction and could worsen the distal injury.

Question 5

You are managing a 38-year-old patient with a traumatic amputation of their left hand. After controlling hemorrhage, you recover the amputated part. What is the proper procedure for preserving the part for potential re-plantation?

Accepted Answer

Wrap the hand in saline-moistened gauze, place it in a sealed plastic bag, and place the bag in a cooler with ice.

Answer

The proper procedure is to keep the amputated part cool and moist without causing frostbite or water damage. This is achieved by wrapping the part in saline-moistened gauze, placing it in a sealed waterproof bag, and then placing that bag in a second container with ice or cold packs. [25, 26, 27] The part should never be placed directly on ice or immersed in water. [27]
