23. Criteria of Stability

24. Compression fractures rarely require surgery
Surgery is indicated if PLC disrupted
Relative indications for surgery
single level lumbar VB height loss >50 %
single level thoracic VB height loss >30 %
combined multi-level height loss >50 %
relative segmental or combined kyphosis >30 º

25. Burst Fx

26. Unstable Burst Fx Related to PLC integrity >30 º relative kyphosis
Loss of vertebral body height > 50%
Biplanar deformity on AP x-ray
MRI finding of disrupted PLC

27. Stable Burst Fx Criteria (burst with intact PLC)
<20-30 º kyphosis(controversial)
<50% lumbar canal compromise
<30% thoracic canal compromise
TLSO/Jewitt brace for comfort
