Percutaneous pedicle screw fixation combined with vertebroplasty for the treatment of Genant Ⅲ degree osteoporotic vertebral compression fractures / 中国骨伤

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of percutaneous pedicle screw fixation(PPSF) combined with percutaneous vertebroplasty (PVP) in the treatment of Genant Ⅲ degree osteoporotic vertebral compression fractures (OVCFs).@*METHODS@#The hospitalized 83 patients with Genant Ⅲ degree OVCFs treated by PPSF combined with PVP from June 2015 to June 2017 were retrospectively analyzed, and 83 patients treated by PVP alone from January 2013 to June 2016 were randomly selected as the control group. There were 19 males and 64 females with an average age of (73.6±11.0) years in combined group with treatment of PPSF and PVP. There were 15 malesand 68 females with an average age of (75.5±10.6) years in control group. The anterior edge height of the vertebral body and Cobb angle before operation, 1 day, and 6, 12, 24 months after operation were compared between two groups. Visual analogue scale(VAS) and Oswestry Disability Index (ODI) were used to assess the pain level and daily lumbar dysfunction for patients, respectively. The complications were observed.@*RESULTS@#The follow-up time of all patients was more than 2 years. The combined group and control group were (24.3±10.2) months and (27.5±14.8) months, respectively. There were no statistically significant differences in the anterior edge height of the vertebral body and Cobb angle at 1 day after surgery between two groups (>0.05), and there were statistically significant differences at 6, 12, 24 months after surgery between two groups (<0.01). The difference in ODI and VAS scores at 6 and 12 months after operation between two groups was statistically significant (<0.05). Postoperative complications incontrol group were higher than those in the combined group.@*CONCLUSION@#PPSF combined with PVP for the treatment of Genant Ⅲ degree OVCFs is superior to PVP alone in terms of vertebral height loss, patient satisfaction, and complications.
