Curative effect of short segment of unilateral laminectomy decompression of intervertebral bone graft fusion with pedicle screw fixation in treatment of lumbar spine instability

Abstract

Objective To investigate the curative effect of short segment of unilateral laminectomy decompression of intervertebral bone graft fusion with pedicle screw fixation in treatment of lumbar spine instability. Methods 100 cases with lumbar instability were randomly divided into the study group and control group with 50 cases in each group,the study group was treated with short segment of unilateral laminectomy decompression of intervertebral bone graft fusion with pedicle screw fixation for treatment, while the control group was treated with conventional methods of treatment. The intraoperative, postoperative situation and clinical efficacy of the two groups were observed and compared. Results The operation time, intraoperative bleeding, drainage, hospital stay and cost of hospitalization of the study group were(121.31±13.73)min, (151.24±24.65)mL, (35.34±6.79)mL,(12.03±3.22)d and(22 012.23±3 018.67)yuan respectively, which were significantly lower than those of the control group[(161.32±11.60)min,(201.32±25.46)mL,(102.35±11.87)mL,(19.42±4.31)d and(26 278.65±3 216.53)yuan](t=9.829,10.829,7.984,10.983,9.593,all P<0.05). The excellent and good rate of the study group was 92%, which was significantly higher than 70%of the control group(χ2=13.927,all P<0.05). Conclusion Short segment of unilateral laminectomy decompression of intervertebral bone graft fusion has a high curative effect in the treatment of lumbar instability, with short operation time and hospitalization time, less blood loss and postoperative drainage volume, low medical cost, which is a good operation scheme.
