Abstract:

BACKGROUND: Incidence of postoperative infection in lumbar surgery is higher than that in cervical surgery. However, there are few studies on the relationship between surgical sequence and incision infection.

OBJECTIVE: To investigate whether surgical sequence is a risk factor for postoperative incision infection.
METHODS: Clinical data of 778 patients with lumbar disc herniation and lumbar spinal stenosis undergoing posterior surgical treatment were analyzed retrospectively. Age, sex, surgical sequence, operation time, blood loss, blood transfusion, internal fixator usage, Cage usage and surgical segment were used for single-factor analysis, and risk factors were confirmed by Logistic regression analysis.
RESULTS AND CONCLUSION: (1) In this study, 778 lumbar disc herniation and lumbar spinal stenosis patients had a 4.2% incidence of infection (33/778), including 23 cases of superficial wound infection and 10 cases of deep wound infection. (2) The surgical sequence (P=0.020, OR=3.050, 95%CI=1.196-7.780), age (P=0.019, OR=2.123, 95%CI=1.133-3.979), operation time (P=0.034, OR=3.035, 95%CI=1.089-8.457) and blood loss (P=0.024, OR=2.059, 95%CI=1.099-3.860), were the risk factors for postoperative infection. (3) The incision length (P=0.106, OR=1.805, 95%CI=0.881-3.969), intraoperative blood transfusion (P=0.107, OR=2.171, 95%CI=0.846-5.570), and surgical segment (P=0.206, OR=0.578, 95%CI=0.223-1.499) had no significant effect on postoperative infection. (4) In summary, for lumbar disc herniation and lumbar spinal stenosis patients except age, operation time, and intraoperative blood loss, surgical sequence is a critical risk factor for incision infection after posterior approach surgery in patients with lumbar disc herniation and lumbar spinal stenosis.
