A 21-year old previously healthy male presents to the trauma bay 8 hours after a helicopter evacuation from a national park with a suspected cervical spine injury. He reports he dove into a lake without understanding the depth and hit a rock. On primary exam he has a 5 cm laceration over the parietal region of his skull with no other aparent injuries in his extremities or abdomen. His heart rate is 57 and blood pressure is 92/70 despite resuscitation efforts with fluids. He is unable to move his arms or his legs and denies peri-anal sensation. He has absent patellar reflexes. When performing a rectal exam, no anal sphincter contraction occurs when the indwelling catheter is pulled. His abdomen is soft and painless. A CT scan of the chest, abdomen, and pelvis is negative except for the cervical spine injury shown in Figure A. Which of the following most accurately describes his American Spinal Injury Association (ASIA) Impairment Scale level:
Unable to determine ASIA Impairment Score

5/5 strength in deltoid function
2/5 strength in triceps function
0/5 strength in the instrinic hand muscles
A 25-year-old male is involved In a motor vehicle accident. He is awake and alert and able to follow commands. He is unable to move his extremities, but has intact perianal sensation and an intact bulbocavernosus reflex. Representative injury CT scan sequences are shown in Figures A, B and C What is his most likely ASIA score at this point in time?

A 26-year-old arena football player is seen in the emergency room after he was injured playing football. On physical exam the patient has 4/5 strength in his deltoid, and 0/5 strength in the remainder of his extremities. He has no perianal sensation or rectal tone, but his bulbocavernosus reflex is intact. He has no other injuries except for those seen in Figures A and B. Which of the following is true?
The patient has a complete injury, so early decompression (< 24 hours) will not increase the liklihood of neurologic recovery compared to delayed treatment
The patient has an incomplete injury, and he should be taken to the OR for early decompression (< 24 hours) to improve neurologic recovery
The patient has a complete injury, but early decompression (< 24 hours) will increase the likelihood of neurologic recovery
The patient has a complete injury, and early decompression (< 24 hours) will increase risk of mortality within 30 days of the injury
The patient has a complete injury, and early decompression (< 24 hours) will increase the peri-operative complications
An 18-year-old male is evaluated for a suspected spinal cord injury. His neurological exam shows diminished sensation below the T7 level. His bulbocavernosus reflex is intact. Which physical finding of motor function, below the affected neurological level, would classify this injury as an ASIA B according to the American Spinal Injury Association impairment scale?
More than half of the major muscles demonstrate palpable or visible muscle contraction
At least half of key muscles have a muscle grade of 5.
More than half of key muscles have a muscle grade less than 3.
At least half of key muscles have a muscle grade of 3 or more.
No motor function preserved more than 3 levels below the level of neurologic injury
An 17-year-old football player is brought to the emergency room following a tackling injury 90 minutes prior. On arrival to the emergency room he is alert and oriented. On physical exam he has tenderness in his posterior midline cervical spine. He reports intact sensation in his upper and lower extremities. He motor exam shows he has some motion in his arms and legs, but is unable to lift his legs or arms against gravity. His bulbocavernosus reflex is absent. Which of the following statements is true regarding the administering a dose of Methylprednisolone 30 mg/kg bolus followed by a 5.4 mg/kg/hr infusion x 24 hours?
It is not supported by current literature - recent studies have shown that while there are no associated complications, there is not significant benefit.
It is not supported by current literature - recent studies have shown an increased risk of complications with no clear evidence of benefits
It is supported by current literature - recent studies have demonstrated few harmful side effects, which are outweighed by the large potential benefits
It is supported by current literature - recent studies have shown only a mild benefit, but due to the high safety profile, the benefits still outweigh the risks
There is no clear evidence to recommend for or against the administration of Methylprednisolone
A 36-year-old male involved in a high speed motor vehicle accident is found on exam to have Grade 2 of 5 motor strength in 80% of his key muscle groups in his lower extremity. His perianal sensation and rectal tone are intact. A bulbocavernosus reflex is present. His sensation is decreased from a point at the intersection of the mid-clavicular line and the 4th intercostal space at the level of the nipples distally. Based on the American Spinal Injury Association (ASIA) classification system, what ASIA grade is he?
A 49-year-old male fell from a height of 10 feet while cleaning his roof. He sustained the isolated injury shown in Figures A and B. Upon transfer from the outside hospital 10 hours later, he has 0/5 motor strength in bilateral lower extremities, no sensation distal to umbilicus, and an intact bulbocavernosous reflex. He has no perianal sensation or rectal tone. He received no medical management at the outside hospital. Which of the following is the most appropriate use of methylprednisolone in this patient.?
Initiate high-dose methylprednisolone with a loading dose of 30mg/kg and a drip of 5.4 mg/kg/hr
Initiate high-dose methylprednisolone, without a loading dose, at 5.4 mg/kg/hr
Do not initiate treatment with methylprednisolone
Initiate high-dose methyprednisolone if his neurologic status does not improve over the next 14 hours
Administer a one-time dose of methylprednisolone at a dose of 30 mg/kg
A 23-year-old man falls down a flight of stairs while intoxicated and is brought to the emergency room the following morning. On physical exam he has no motor function in his upper and lower extremities. Sensory exam shows diminished but present sensation in the perianal area and in the lower extremities. Reflex exam shows his bulbocavernosus reflex is intact. The inital CT and MRI are seen in Figures A and B. According to the American Spinal Injury Association (ASIA), how would this injury be classified?
