Analysis of remaining symptoms after discectomy with different operation for lumbar disc herniation

Objective To analyze the incidence of remaining symptoms after discectomy with different operation, and investigate its causes and clinical significance. Methods Two hundred and twenty-four patients were followed up. The incidence of remaining symptoms and clinical situation after discectomy were observed with different operation: discectomy (110 patients, single group), discectomy with bone grafting internal fixation (70 patients, fusion group), and discectomy with dynamic fixation (44 patients, non-fusion group). The SPSS 19.0 software was used to analyze the data. Results One hundred and sixpatients (47.32%,106/224) occurred remaining symptoms in 224 patients. In single group was 69 patients (62.73%, 69/110), in fusion group was 26 patients (37.14%,26/70), and in non-fusion group was 11 patients (25.00%, 11/44). The incidence of remaining symptoms among three groups was significant difference(χ2=22.177, P=0.000). The incidence of remaining symptoms in single group was significantly higher than that in non-fusion group and fusion group (χ2=17.921, P=0.000; χ2=11.235, P=0.001). The incidence of remaining symptoms in non-fusion group and fusion group had no significant difference (χ2=1.817, P=0.178). Conclusions There is significantly different in the incidence of lumbar disc herniation with different surgery methods. Discectomy with bone grafting internal fixation and with dynamic fixation can effectively reduce the incidence of remaining symptoms.
