Orthopaedic Injuries Quiz: Open Fractures & Patella Dislocations

Questions and Answers

An open fracture is MOST accurately defined as a fracture in which:

Bone ends protrude through the skin.

A large laceration overlies the fracture.

A bullet shatters the underlying bone.

The overlying skin is no longer intact. (correct)

Crepitus and false motion are:

Indicators of a severe sprain.

Positive indicators of a fracture. (correct)

Only seen with open fractures.

Most common with dislocations.

Which of the following statements regarding compartment syndrome is correct?

Compartment syndrome occurs because of increased pressure within the bone cavity.

In most cases, compartment syndrome develops within a few minutes after an injury.

Compartment syndrome typically develops within 6 to 12 hours after an injury. (correct)

Most cases of compartment syndrome occur following a severe fracture of the pelvis.

Study Notes

Orthopaedic Injuries Overview

An open fracture is defined as a fracture with the overlying skin no longer intact.
Crepitus and false motion are positive indicators of a fracture.
Compartment syndrome develops typically within 6 to 12 hours after an injury, usually due to increased pressure within tissue compartments.

Types of Fractures and Injuries

A displaced fracture is most likely to result in deformity compared to other types of injuries.
A supracondylar or intercondylar fracture refers specifically to a fracture of the distal humerus.
The term "hip fracture" accurately describes a fracture of the proximal femur.

Assessment and Management

Patients with possible scapula fractures require careful assessment for potential breathing problems due to the location of the injury.
In cases of crepitus in the pelvis, stabilization with a pelvic binder is crucial to manage possible internal bleeding.

Specific Patient Scenarios

For a dislocated patella, keep the knee flexed and secure it with padded board splints.
If unable to palpate a radial pulse in an elbow deformity, apply gentle manual traction in line with the limb and reassess for pulse.

Emergency Responses

For severe injuries, such as a 54-year-old male with a gunshot wound, controlling bleeding and covering the wound is a priority.
A pelvic fracture with hypotension poses a significant threat to life, necessitating immediate medical attention.

Splinting and Stabilization

Splinting musculoskeletal injuries should be done before moving the patient unless they are clinically unstable.
The zone of injury includes the area of soft-tissue damage surrounding the injury, critical for understanding the extent of the injury.

Complications and Hazards

The most significant hazard associated with splinting is the potential for delaying transport of critically injured patients.
It is important to splint an injured limb in the position of deformity if resistance is encountered or if severe pain occurs.

Anatomy and Physiology

Skeletal muscle connects to bones via tough, ropelike structures known as tendons.
The musculoskeletal system comprises the bones and voluntary muscles of the body, facilitating movement and support.
