Abstract:
Objective To evaluate the clinical curative efficacy and to explore the leaking pathway of bone cement to verte‐bral canal through treating osteoporotic vertebral burst fractures (OVBF) by using percutaneous kyphoplasty(PKP) .Methods Ac‐cording to AO classification ,45 OVBF patients with 45 vertebras in the Erdos Central Hospital from October 2005 to May 2013 were treated by using PKP .The pathway of bone cement leaking to spinal canal and intervertebral space was determined by postop‐erative CT plain scan .The postoperative vertebral height ,Cobb angle and spinal stenosis improvement were measured .The change of VAS were compared between before and after operation .Results There were 2 cases of bone cement leaking to spinal canal .The leaking passway was mainly through basivertebral foramen .The leakage of bone cement to superior intervertebral space was higher than that to lower intervertebral space .The recovery of the vertebral height ,correction of Cobb angle and pre‐and post‐operative VAS scores had statistically significant differences (P<0 .05) .The spinal stenosis rate had no statistical difference between before and after operation(P>0 .05) .Conclusion PKP for treating OVBF is not a contraindication .The main pathway of bone cement lea‐king to spinal canal is basivertebral foramen after the treatment of OVBF by using PKP ,the leakage to intervertebral space is relat‐ed with the endplate damage .
