Purpose
To find the factors that affecting surgical outcome after vertebroplasty and kyphoplasty in osteoporotic compression fracture.
Materials and Methods
Pre-operative, post-operative, technical, radiological factors of patients who diagnosed osteoporotic compression fracture and treated with vertebroplasty or kypholasty during from January 2008 to December 2010, were compared by outcomes that acute and chronic back pain, refracture rate and maintenance of the reduction of body height.
Results
The period of acute pain after the operation was less than 3 days in groups of trauma( p=0.0262) and hospital treatment(p=0.0113) before the operation as pre-operative factors. When it comes to technical factors, the cases of vertebroplasty(p<0.0001), injection of cement(p=0.0053), the case without leakage of cement(p=0.007) and the case being under anesthesia (p<0.005)achieved statistical significance. In the groups who got conservative treatment less than 1 week (p=0.0119) and local anesthetics(p=0.0246), refractures occurred many times. The groups of non-trauma(p=0.0105), having had more than 30% compression(p=0.0244) and the group that prescribed bisphosphonate(p=0.0286) statistical significantly maintained restoration.
Conclusion
Conservative treatment in the hospital for more than 1 week before the operation, operation being under anesthesia and intake of bisphosphonate after the operation put positive effects on the outcome of vertebroplasty and kyphoplasty.
