Abstract:[Objective] To investigate the clinical outcomes of manual reduction under general anesthesia and percutaneous cementaugmentedpedicle screw fixation in the treatment of stage IIIa Kümmell’s disease. [Methods] A retrospective study was done on 16 patientswho received manual reduction and percutaneous cement-augmented pedicle screw fixation for stage IIIa Kümmell’s disease in our hospitalfrom January 2019 to February 2023. Clinical and imaging data were evaluated. [Results] All the 16 patients were successfully operated onwithout any serious complications such as bone cement leakage, nerve and vascular injury, with the mean operation time of (96.6±11.1) minand the mean intraoperative bleeding of (93.4±13.6) ml. During the follow-up period lasted for more than 12 months, none of the 16 patientshad any recurrence of severe low back pain or revision surgery. Compared with those preoperatively, the VAS score [(7.4±0.7), (2.7±0.6),(2.3±0.7), P<0.001] and ODI scores [(74.5±3.1), (33.4±3.9), (29.9±2.8), P<0.001] were significantly improved before discharge and at thelatest follow-up. As for imaging, compared with those preoperatively, the vertebral anterior height (AH) was significantly increased [(12.2±1.1) mm, (20.4±0.9) mm, (20.2±0.9) mm, P<0.001], while the local kyphotic angle (LKA) was significantly decreased before discharge and atthe latest follow-up in the 16 patients. [Conclusion] Manual reduction and percutaneous bone cement augmented pedicle screw fixation inthe treatment of stage IIIa Kümmell’s disease trauma has the advantages of less trauma, rapid recovery, and does achieve satisfactory clinicalconsequence.
