A 61-year-old male patient with an A4-type osteoporotic burst fracture at the L1 level and a McCormack load-sharing score of 8 underwent short-segment cement-augmented pedicle screw fixation with kyphoplasty and SpineJack® implantation. A: The Cobb angle of the thoracolumbar segment was measured on a sagittal spine computed tomography scan (anglepre). B: Lateral spine radiography on postoperative day 1 showing anglepost. C: Pedicle screw and rod dislodgement (arrowhead) at 9-month postoperative lateral spine radiography follow-up and angleend. anglepre, preoperative Cobb angle; anglepost, 1-day postoperative Cobb angle; angleend, 9-month follow-up Cobb angle
