Findings:
Known, old compression fracture of T11 and T12 vertebral body with unchanged, significant loss of height of both vertebrae and frontal spilt with gas in T12 vertebral body. No interval changes.
Newly appreciated burst fracture of L1 vertebral body involving the superior and inferior endplates with mild (20%) loss of height and minimal retropulsion, without significant central canal stenosis.
Unchanged Schmorl nodes at the superior endplate of T10 and L2 and at inferior endplate of L3 with associated loss of height.
An oblique fracture line is noted through the sacral alaa bilaterally, surrounded by a zone of stippled sclerosis. No involvement of the neural exit foraminal.
Also, partially imaged subacute fractures of the superior pubic ramus are seen bilaterally with mild displacement on the left.
Scoliotic deformity and mild to moderate spondylodegenerative changes of the spine are seen, without any significant central canal or neural exit foraminal stenosis. Moderate osteoarthritis of the sacroiliac joints are seen bilaterally.
Moderate atherosclerotic changes of the abdominal aorta and the iliac arteries. A simple cortical renal cyst is seen on the right upper pole. No intra abdominal free fluid.
Conclusion:
Acute vertebral burst fracture of L1 vertebral body with mild loss of height and minimal retropulsion without any relevant stenosis.
Known, old high-grade compression fractures of T11 and T12.
Subacute fractures of superior pubic ramus and the sacral ala are seen bilaterally with mild displacement of the superior pubic ramus on the left. Further evaluation with CT pelvis is advised.
