Cortical bone trajectory versus cement-augmented pedicle screws in osteoporotic lumbar surgery: 24-month patient-reported outcomes and recorded complications.
PURPOSE Cement-augmented pedicle screws (CPSCA) and cortical bone trajectory (CBT) screws are used to enhance the fixation strength in osteoporotic bone, but direct comparative clinical evidence remains limited. This study compared 24-month patient-reported outcomes, hospital stay, and complication profiles after CBT v...
