Clinical Results Of Vertebral Compression Between Metastatic Tumor And Osteoporsis With Percutaneous Vertebroplasty

Objective To review and analyze the clinical curative effect in metastatic tumorVertebral Compression Fractures and Osteoporsis Vertebral Compression Fractures patientsafter Percutaneous Vertebroplasty.Methods From January2007to January2011,there were95cases who have anoperation because of Vertebral Compression Fractures in the department of orthopedics ofthe Fourth Affiliated of Soochow University. Adopting questionnaire investigating way tocollect the data of evaluating curative effect by telephone, letter and out-patient callback.According to the reason of Vertebral Compression Fractures, all patients were divided intotwo groups,group A(metastatic tumor),group B (Osteoporosis disease) to analyze theclinical effect according to the assessment scale proposed by Even Lin Liefa and JapaneseOrthorpeadic Assocition(JOA)、Visual analogue scales(VAS)、SF-36and radiographic.Investigatings were learned by statistics. Something was down to compare theimprovement rate of the patients and radiographic with different groups, at same time,analyzing association of the injection of PMMA and the pain grade of VAS.Results1According to the assessment scale proposed by Even Lin Liefa,there wasstatistical difference between the two groups (P＜0.01).2In two gruops, there was statistical difference between the pre-operative andpost-operative of the scores of VAS, JOA and SF-36(P<0.05).3In two gruops, there was no statistical difference between the post-operative ofthe height of anterior and middle portion of the vertebral body (P>0.05). there was nostatistical difference between the pre-operative and post-operative of the scores of theCobb angle.4There was no statistical difference of the injection of PMMA between thegroup A、 B(P>0.05)，The injection of PMMA were no associated with the pain grade ofVAS. Conclution:1) Percutaneous Vertebroplasty is a safe, effective and minimal invasivetechnique in treatment and pain relief.2) The clinical curative effect is satisfied, and there was statistical differencebetween two groups，group B better than group A.
