Orthopaedic Technologist Certified Test Orthopaedic Technologist Certified Fracture Classification and Management 1 — Questions and Answers
Question 1: Which fracture classification system uses Types I, II, and III to describe open fractures based on wound size and soft tissue damage?
- AO/OTA Classification
- Gustilo-Anderson Classification (Correct answer)
- Garden Classification
- Neer Classification
Correct answer: Gustilo-Anderson Classification
The Gustilo-Anderson classification categorizes open fractures into Types I, II, and III based on wound size, contamination level, and soft tissue injury severity.
Question 2: A fracture line running perpendicular (at a right angle) to the long axis of the bone is best described as which type?
- Oblique
- Spiral
- Transverse (Correct answer)
- Comminuted
Correct answer: Transverse
A transverse fracture runs at approximately 90° to the long axis of the bone and is typically caused by direct bending force.
Question 3: Which fracture type is characterized by three or more bone fragments at the fracture site?
- Greenstick
- Stress
- Comminuted (Correct answer)
- Impacted
Correct answer: Comminuted
A comminuted fracture produces three or more bone fragments at the injury site and is commonly the result of high-energy trauma.
Question 4: A Colles' fracture is a distal radius fracture characterized by which deformity?
- Volar angulation
- Dorsal angulation (Correct answer)
- Radial deviation only
- Ulnar deviation only
Correct answer: Dorsal angulation
A Colles' fracture involves dorsal angulation of the distal radius fragment, producing the classic 'dinner fork' deformity on lateral X-ray.
Question 5: Which fracture type is most commonly seen in pediatric patients due to incomplete bone ossification?
- Stress
- Pathologic
- Greenstick (Correct answer)
- Avulsion
Correct answer: Greenstick
Greenstick fractures occur in children because their incompletely ossified bones are more pliable, causing the bone to crack on one cortex without complete separation.
Question 6: The Garden classification system is used specifically to categorize fractures of which anatomical location?
- Proximal humerus
- Distal femur
- Femoral neck (Correct answer)
- Tibial plateau
Correct answer: Femoral neck
The Garden classification (Grades I–IV) categorizes intracapsular femoral neck fractures to guide treatment decisions and predict avascular necrosis risk.
