Ortho Tech Exam 1 2025 QUESTIONS AND CORRECT ANSWERThe five stages of normal fracture healing in correct order include: - answer>>>Inflammation,
cellular proliferation, callus formation, ossification, remodeling
The normal length of time for a fracture to heal is: - answer>>>8-12 weeks
Diagnostic Ultrasound (Sonography) - answer>>>High-frequency sound waves that penetrate
the body to produce images of internal structures in real time. Used to identify tumors,
enlarged lymph nodes, heart abnormalities, soft-tissue injury, bleeding, and fetal development.
Useful in the diagnosis of tissue tears, blood clots, and deep vein thrombosis. No documented
side effects.
Electromyography (EMG) - answer>>>EMG involves inserting a needle into a muscle and
recording the electrical activity. Result is recorded on an electromyogram. Used to determine
the cause of muscle weakness and abnormal nerve conduction that may be due to medical
conditions.
Nerve Conduction Study (NCS) - answer>>>Measures the electrical signals of a nerve associated
with a specific muscle. Typically performed in conjunction with electromyography. Involves
stimulating a nerve and recording the strength of the neurological reaction and the amount of
time it takes to contract the muscle being tested.
electrocardiography - answer>>>Electrodes are placed on the chest to detect the electrical
activity of the heart. Electrical activity is charted as a graph on an electrocardiogram (ECG) as
waveforms and analyzed to determine if there are any abnormalities. ECG is used to identify
ischemia, heart attack, pericarditis, valvular disorders, electrolyte imbalances, palpitations,
angina.
Radionuclide Bone Scan - answer>>>A nuclear imaging test involving the injection of a short-
lived radionuclide to assess abnormalities of the bones. A radionuclide tracer is attracted to
increased metabolic activity. Used to identify stress fractures, bone infections, bone cancer,
and arthritis. Patients who are pregnant or allergic to red dye should not have a bone scan.
, Salter-Harris Fracture Classification - answer>>>I: Straight across the plate - causing separation.
II: Across plate and metaphysis.
III: Across plate and epiphysis.
IV: Through the metaphysis, plate, and epiphysis.
V: Compression fracture along plate.
A Colles fracture is defined as - answer>>>fracture of the distal metaphysis of the radius; the
featured segment is displaced dorsally
Bennett's fracture - answer>>>An unstable fracture of the base of the first metacarpal
Boxer's fracture - answer>>>Common signs of this fracture included a shortened 5th
metacarpal phalangeal joint and a 5th finger that overlaps the 4th finger when a fist is made
Potts fracture - answer>>>A fracture that includes the medial malleolus and the distal fibula
Mallet fracture - answer>>>avulsion fracture that occurs at the distal phalanx of a finger
Maisoneuve fracture - answer>>>Forceful external rotation of the foot relative to the tibia can
sprain the deltoid ligament or distal syndesmosis joint. It is also a mechanism for this trial
fracture of the proximal 1/3rd of the fibula
Which fracture occurs at the base of the 5th metatarsal at the junction of the metaphysis and
diaphysis? - answer>>>Jones fracture
