Abstract:

Objective　To provide anatomic data for less complications of bone cement leakage in PKP and PVP.　Methods　A total of 40 health adults underwent multi-slice CT thin slice scans and three-dimensional reconstruction. In the horizontal and sagittal CT reconstruction images, display frequency of basivertebral foramen （BF) and vertebral vein (VV）of the branches of basivertebral venous system in vertebral bodies of T8~L5 were calculated. The sagittal diameter of vertebral body (VD), BF weight (BFW), BF depth (BFD), BF high (BFH) were measured. The distance between the BF and each side inthe horizontal and sagittal CT images were also measured. The measured parameters were analyzed statistically.　Result　Display frequency of BF and VV was gradually increasing from T8 to L5. Display frequencies of BF and VV in vertebral bodies were no significantly different between male and female (P>0.05). The distance from the BF to left or right side in the horizontal CT images were not significantly different (P>0.05). The distance from the BF to the cranial or caudal endplate in the saggital CT images were significantly different (P<0.05). The distance from the BF to the cranial endplate was shorter than to the caudal endplate.　Conclusion　For clinic operators, the knowledge of anatomic distribution of BF and VV in vertebral bodies helps to reduce the occurrence of bone cement leakage in PVP and PKP.
