Over-extending reduction combined with unilateral approach percutaneous vertebroplasty for the treatment of vertebral compression fractures due to 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 A total of 16 patients with vertebral compression fractures due to osteoporosis were treated with over-extending reduction by using traction on the operation table,and then PVP through trans-single-pedicular approach 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 Technical success was achieved in 20 vertebrae of 16 cases.Bone cement leakage was observed in front of the vertebral body(n = 5),in the side of vertebral body(n = 20) and within the intervertebral disc(n = 2).After the treatment VAS score decreased from preoperative 8.5 ± 1.2 to postoperative 2.5 ± 1.4.The vertebral height recovery ratio was(40.1 ± 23.5)%.After the surgery,the VAS score and the vertebral height were significantly improved(P 0.05).Conclusion The over-extending reduction combined with PVP through trans-single-pedicular approach is an effective treatment for vertebral compression fractures caused by osteoporosis.
