Abstract: 【Abstract】 Objective To assess the results of PVP, PKP and conservative therapy for the treatment of osteoporotic vertebral compression fractures with the pain degree and vertebral body height recovery. Methods A retrieval data for osteoporotic compression fractures was analyzed. Forty?five patients were included in the study and were assigned to three groups，percutaneous vertebroplasty（PVP） group，percutaneous kyphoplastygroup（PKP）group and conservative therapy，15 cases in each group. Clinical effects and Visual analogue scales（VAS），Oswsetry Disability Indexs（ODI）were recorded，and evaluated by follow?up. Results Restoration of vertebral height of anterior?wedge fracture was remark? able. Postoperative analgesic effect in PVP and PKP group was better than that of conservation treatment group, but there were not significant differences in the long?term pain relief effect between three groups. There were correlation between pain score with compression degree of anterior?wedge of vertebral body. There were four cases of bone cement leakage in PVP group during operation，and two cases in PKP group. In conservation group, pulmonary infection and bed?sore occurred in each two cases during. Conclusion Anterior wedge compression fractures in vertebrae was associated with moderate pain degree. PVP and PKP were superior to conservative treatment in short and medium term after operation.
