Abstract:
Objective:To analyze the effect of inter-spinal distraction fusion and fixation (ISDFF) combined with limited decompression on the treatment of lumbar spinal stenosis in elderly patients.Methods:A total of 32 elderly patients with lumbar spinal stenosis, aged from 80 to 87 years old (mean age: 82.0±2.0 years) including 10 males and 22 females, in the Department of Orthopedics, Beijing Friendship Hospital, Capital Medical University from January 2016 to January 2020 were enrolled in this retrospective study. Clinical evaluation and imaging measurement were performed before operation, after operation, 6 months and 24 months after operation. SPSS software was used for statistical analysis. Measured data of normal distribution were expressed as means±standard deviation. One way analysis of variance was used for comparison between groups. Paired t-test was used to compare between preoperative and postoperative as well as between preoperative and 24 months′ follow-up. Results:All of the 32 patients had one or more common accompanying diseases, such as hypertension, diabetes, coronary heart disease, and so on. All patients were successfully completed the operation with a total of 32 segments. VAS score was decreased from (6.22±0.91) before operation to (1.94±0.76) at 24 months( t=16.52, P<0.001). ODI score was also demonstrated the similar trend, from (54.17±10.65) preoperatively to (19.91±4.20) at 24 months follow-up( t=15.89, P<0.001). JOA score was significantly increased from (11.69±3.36) before surgery to (23.44±1.66) at the last follow-up ( t=-19.90, P<0.001). In the change of imaging, the intervertebral angle was decreased from preoperation (9.12±4.65) to (6.77±2.70) at 24 months( t=3.53, P=0.001). The posterior disk height was increased from (0.68±0.19) cm to (0.76±0.19) cm at the last follow-up( t=-2.45, P=0.020). Conclusions:As a new type of minimally invasive internal fixator, the ISDFF combined with limited decompression can relieve the pain of elderly patients with lumbar spinal stenosis and improve the quality of life. It is suitable for the treatment of elderly patients with lumbar spinal stenosis.
