[Objective] To introduce a new technique of bone cement injection, which is safe, reliable and effective. [Methods] A retrospective study was conducted on 99 cases of undergraduate patients from 2015 to 2020, including 32 males and 67 females, aged from 64 to 85 years [(76.1 8.5) years]; The distribution of vertebral injury: T10 vertebral body 10 cases, Tll vertebral body 12 cases, T12 vertebral body 38 cases, L1 vertebral body 32 cases and L2 vertebral body 17 cases; There are 35 degree I wedge fractures, 20 degree II wedge fractures, 8 degree III wedge fractures, 6 degree I double concave fractures, 9 degree II double concave fractures, 17 degree I compression fractures and 4 degree II compression fractures. The three techniques of puncture cone target puncture fracture area, injection of bone cement target assisted by lateral injection rod and tail anchoring of bone cement pedicle were comprehensively applied to percutaneous vertebroplasty, and the operation effect was evaluated by X-ray and CT during and after operation. [Results] All the operations were successfully completed, the height of the anterior edge of the fractured vertebral body was obviously recovered, the leakage of bone cement was less, and the postoperative pain was obviously relieved. [Conclusion] The combined application of three techniques, namely target puncture in fracture area, injection of bone cement with lateral push rod and tail anchoring of bone cement pedicle, can reduce bone cement in percutaneous vertebroplasty.
