Clinical Observation of 27 Cases with Osteoporotic Vertebral Compression Fractures Treated by PVP

Objective To investigate the leakage of bone cement and effectiveness of percutaneous vertebroplasty for osteoporosis vertebral compression fractures. Methods 42 vertebrae of 27 patients(6 male and 21 female;age range 54 ～ 89 years with the mean age of 66.7 years) with osteoporosis compression fractures were performed percutaneous vertebroplasty from January 2008 to December 2010. The leakage of bone cement was evaluated according to the post-operative image,and the pain before operation and in the second day after operation was measured by using the visual analogue scale(VAS) . Results The total of 42 vertebral bodies in 27 cases were successfully implemented percutaneous vertebroplasty,the injection volume of bone cement per vertebra was 1.5 ～ 5 ml,with an average of(2.58 ± 0.30) ml,there were seven vertebrae leakage,one was in the intervertebral discs,and the remaining six were adjacent vertebral body leakage,and the overall leakage rate was 16.7%(7/42) ,no nerve root and spinal cord compression symptoms and other complications occurred. The mean VAS pain score decreased significantly(P 0.001) from(7.5 ± 0.6) before PVP to(1.9 ± 0.3) after PVP. Conclusion PVP is effective in facilitating pain relief in patients with osteoporotic vertebral compression fractures,and is easy to be performed in basic hospital in China.
