Clinical effect of over-extending reduction combined with percutaneous vertebroplasty on vertebral compression fractures caused by osteoporosis

Objective To assess the clinical effect of over-extending reduction combined with percutaneous vertebroplasty(PVP)in treating vertebral compression fractures caused by osteoporosis.Methods From August 2010 to August 2011,38 patients(46 vertebraes)with vertebral compression fractures caused by osteoporosis were treated with over-extending reduction by using traction on the operation table,and then PVP was performed on the fractured vertebra.The visual analogue scale(VAS)was used to evaluate the clinical effectiveness.The preoperative and postoperative heights of the fractured vertebral body were determined,and the vertebral height recovery ratio was calculated.Results The total operations were done successfully,paravertebral leakage of filling materials occurred in 6 patients,and there was no neurological symptoms development.Postoperative back pains(in 24 h)were significantly alleviated in all patients.Patients were followed up for 12 to 28 months,with an average of 18.6 months.All patients showed no neurological symptoms or other complications o.Pre-operative,24 h,1 month and 12 months post-operative pain intensity(VAS score)were 8.4±0.6,2.4±0.4,2.5±0.7,2.4±0.6,respectively.The anterior,the middle and posterior vertebral height were restored by(57.2±16.4)%,(46.5±12.6)%,(49.6±13.3)%,respectively,and kyphotic angle was corrected by(56.9±14.1)%(Compared with the Preoperative,P0.05).Conclusion The over-extending reduction combined with PVP is an effective treatment for vertebral compression fractures caused by osteoporosis.
