A 68 years-old woman in O-PKP group with L1, L2 and L4 OVCFs. These intraoperative images demonstrate operation techniques and procedures. The needle via point “O” to the contralateral inferior corner of vertebral body on posteroanterior imaging (A). The entry point “O” is located at the intersection of the posterior-superior margin of the pedicle and lateral margin to superior articular process on lateral imaging (B). These images (C, D) demonstrate an ideal bone cement distribution, the bone cement across the anterior one-third midline and across the midline of the vertebral body.
