ObjectiveTo study the efficacy of minimally invasive percutaneous pedicle screw fixation using Sextant system in the treatment of senile osteoporotic spinal fractures and its effect on neurological function recovery. MethodsEighty-eight senile patients with osteoporotic fractures were selected and were divided into observation group (n=44) and control group (n=44) using random number table. The surgery-related indicators, the preoperative and postoperative Cobb angle and sagittal index, postoperative ODI score and grade of Frankel improvement were compared between the two groups. ResultsCompared with the control group, the operation duration, the incision length, intraoperative blood loss and duration for ambulation were less or shorter in the observation group (P＜0.05). The postoperative Cobb angles and sagittal indices were significantly improved in both groups, but there were no significant differences between the two groups (P＞0.05). The ODI scores in both groups decreased significantly after operation, and the descent range of the score was greater in observation group compared to the control group(P＜0.05). ConclusionFor the elderly patients with osteoporotic fractures, percutaneous pedicle screw fixation using Sextant system can significantly improve the surgery-related indicators, can ensure the correction efficacy of convex deformity, can effectively relieve the nerve damage and improve the quality of life. This approach is worthy of clinical promotion.
