A 12-year-old girl has back pain after falling 20 feet and landing in the sitting position. She has no fractures or other injuries, and her neurologic examination is normal. A lateral radiograph, transverse CT scan, and reformatted sagittal CT scan are shown in Figures 25a through 25c. Which of the following methods is associated with the best long-term outcome?
Hyperextension casting of the thoracolumbar spine for 6 weeks
In situ posterior fusion with instrumentation
Posterior fusion with instrumentation, with sagittal plane correction
Posterior decompression, followed by posterior fusion with instrumentation, with sagittal plane correction
Anterior decompression and partial corpectomy, with anterior instrumentation

In a neurologically intact patient with the injury pattern shown in Figure A, B and C, what is the advantage of surgical treatment compared to early mobilization in a thoracolumbosacral orthosis?
Decreased kyphosis over time
Decreased residual back pain
Lower cost of hospitalization
Earlier return to work
No advantage - equivalent clinical outcomes
You are seeing a 68-year-old female who fell out of her second story apartment window. She complains of severe low back pain and right buttock pain. Her neurologic exam shows she is an ASIA E. Imaging shows a L3 burst fracture with 10 degrees of kyphosis, 30% loss of vertebral body height, and retropulsion of bone with 20% occlusion of the spinal canal. There is no evidence of edema in posterior ligament complex on MRI. What is the most appropriate treatment?
Spinal traction with bedrest for a minimum of 6 weeks
Spinal orthosis and early mobilization as tolerated
Laminectomy and lateral recess decompression
Laminectomy and 4 level posterior instrumented fusion
Anterior corpectomy with decompression and staged 4 level posterior instrumented fusion
In patients with a stable thoracolumbar burst fracture and no neurologic deficits, operative treatment has what long term outcome when compared to nonoperative management.
Improved sagittal balance
Decreased pain scores
Improved return to work status
Increased disability and complications
A 32-year-old male sustained an L4 burst fracture in a car accident five days ago. On initial presentation he was neurologically intact and treated in a thoracolumbar orthosis. In the last two days he has noticed increasing difficulty voiding, decreased perianal sensation, and weakness to ankle plantar flexion. Radiographs, computed tomography, and magnetic resonance imaging are shown in Figures A through D. What is the most appropriate next step in treatment?
Spinal dose corticosteroids with inpatient observation
A decompressive lumbar laminectomy without fusion
Percutaneous posterior instrumented stabilization from L2 to L5 with indirect decompression via distraction ligamentotaxis
Anterior decompresssion with strut grafting followed by posterior instrumentation
A 32-year-old man presents to the emergency department after sustaining a L1 burst fracture in a fall. A careful neurologic exam shows he is an ASIA E. MRI shows mild vertebral retropulsion with 10% central canal stenosis and no evidence of injury to the posterior ligament complex. Which of the following is true regarding surgical decompression and fixation when compared to nonoperative treatment with bracing?
Patients treated with surgery return to work earlier.
Patients treated with surgery have decreased pain scores.
Patients treated with surgery have increased complication rates.
Patients treated with surgery have improved final SF-36 scores.
All of the above
