| Objective To study the effectiveness and safety of cement short segmental fixation for Kümmell disease. Methods The medical records of 25 patients in Peking University People's Hospital who underwent cement short segmental fixation for Kümmell disease from January 2017 to June 2019 were retrospectively reviewed. We recorded the operation duration, intraoperative hemorrhage and cement use. Anterior height of affected vertebral body and Cobb angle were further evaluated by X-ray and CT during follow-up. The visual analog scale (VAS) pain score was used to evaluate the improvement of clinical symptoms,and Oswestry disability index (ODI) was used to assess postoperative functional improvement. Results The VAS grades, ODI scores, anterior heights of affected vertebrae, and Cobb angles showed statistically significant differences between pre- and postoperative and between preoperative and final follow-up values (P<0.05). While ODI scores, anterior heights of affected vertebrae, and Cobb angles showed their statistically significant differences (P<0.05) between postoperative and final follow-up, VAS grades did not(P>0.05). Conclusion Cement-enhanced pedicle screw internal fixation for Kümmell disease can reduce kyphosis, restore vertebral height and relieve pain.Although there may be long-term problems such as vertebral height, the long-term functional recovery of patients is still good and the complication rate is low, hence it is a safe and effective treatment. |
