Certification Comprehensive Examination - National Board for Certification of Orthopaedic
Technologists - 2026/2027 Academic Year - Questions and Answers Covering Four Core Domains,
with the strongest emphasis placed on Demonstrate advanced proficiency in orthopaedic patient
assessment and diagnostic reasoning, Apply current fracture classification systems and
evidence-based management strategies to complex cases and Integrate biomechanical principles
and aseptic techniques in orthopaedic procedures. Every item follows the wording style and level
of reasoning you meet in the real paper, and each one is paired with a clear rationale so the
correct choice is never a guess. Work through the set at your own pace, mark the questions that
slow you down, then come back to them until the reasoning feels automatic. Learners who revise
this way walk into the exam room recognising the pattern behind the questions instead of meeting
them for the first time. Keep going - steady, honest practice is what turns a difficult paper into a
comfortable pass.
Q1 DEMONSTRATE ADVANCED PROFICIENCY IN ORTHOPAEDIC PATIENT ASSESSMENT
AND DIAGNOSTIC REASONING
During a closed reduction of a distal radius fracture, the orthopaedic technologist
applies manual traction and then a sugar-tong splint. Post-reduction radiographs
show residual dorsal angulation of 15°. The patient has no neurovascular
compromise. Which next step is most appropriate?
A. Accept the alignment and proceed with definitive splinting CORRECT
B. Repeat the reduction attempt using a different technique
C. Refer for open reduction and internal fixation
D. Apply a short arm cast instead of the splint
RATIONALE: In an elderly low-demand patient, up to 15° of dorsal angulation is acceptable if the
radial inclination and articular congruity are maintained. This is within the acceptable parameters
for a distal radius fracture. Re-reduction risks soft tissue injury, and surgery is not indicated
without other criteria. The splint is appropriate for initial management.

,Q2 DEMONSTRATE ADVANCED PROFICIENCY IN ORTHOPAEDIC PATIENT ASSESSMENT
AND DIAGNOSTIC REASONING
Which of the following best describes the biomechanical advantage of a long arm
cast over a short arm cast for a midshaft radius fracture?
A. It prevents pronation and supination of the forearm
B. It increases compression at the fracture site
C. It immobilizes the elbow to reduce rotational forces CORRECT
D. It provides better axial alignment
RATIONALE: A long arm cast immobilizes the elbow, which controls rotational forces from the
biceps and supinator muscles that act on the proximal radius. A short arm cast does not
neutralize these forces. Compression and axial alignment are not the primary benefits.
Q3 DEMONSTRATE ADVANCED PROFICIENCY IN ORTHOPAEDIC PATIENT ASSESSMENT
AND DIAGNOSTIC REASONING
A patient with a tibial shaft fracture treated with a cast complains of severe pain
with passive toe extension. Which condition must be ruled out immediately?
A. Deep vein thrombosis
B. Compartment syndrome CORRECT
C. Peroneal nerve palsy
D. Fat embolism syndrome
RATIONALE: Severe pain with passive stretch of the toes is a classic early sign of acute
compartment syndrome. It indicates increased pressure within the anterior compartment. DVT
and fat embolism do not present with this sign. Peroneal nerve palsy may cause weakness but
not pain with passive stretch.

, Q4 DEMONSTRATE ADVANCED PROFICIENCY IN ORTHOPAEDIC PATIENT ASSESSMENT
AND DIAGNOSTIC REASONING
A patient with a suspected scaphoid fracture has negative initial radiographs.
Which of the following is the most appropriate next step in management?
A. Apply a thumb spica splint and repeat radiographs in 10-14 days CORRECT
B. Order an MRI immediately
C. Apply a short arm cast and discharge
D. Reassure the patient and allow full activity
RATIONALE: Initial radiographs may be negative in up to 20% of scaphoid fractures. The
standard of care is to immobilize in a thumb spica and repeat imaging in 10-14 days. MRI is
sensitive but not universally available or cost-effective as a first-line. A short arm cast is
insufficient because it does not immobilize the thumb.
Q5 DEMONSTRATE ADVANCED PROFICIENCY IN ORTHOPAEDIC PATIENT ASSESSMENT
AND DIAGNOSTIC REASONING
Which of the following is a critical step in the application of a hip spica cast to
prevent pressure injuries?
A. Applying the cast in one continuous layer
B. Using a 90-90 position with the hip flexed to 90 degrees
C. Placing padding over the iliac crests and sacrum CORRECT
D. Trimming the cast to allow for abdominal expansion
RATIONALE: Pressure injuries are a major complication of hip spica casts. Adequate padding
over bony prominences such as the iliac crests and sacrum is essential. While the 90-90 position
is often used, it is not the primary preventive measure. Trimming is done for comfort but not
pressure prevention.
