Frequency of short-term complications caused in spondylolisthesis and lumbar disc herniation surgeries in patients with and without instrumentation

Abstract

Knowledge of the prevalence and type of short-term complications after spinal surgery can increase the neuroradiologists' view of the prevalence of short-term complications related to the implantation of surgical instruments and minimize the amount of diagnostic errors. The aim of this study is to evaluation of frequency of short-term complications caused in spondylolisthesis and lumbar disc herniation surgeries in patients with and without instrumentation. Materials and Methods: This study was as cross-sectional descriptive-analytical and the target population included all patients who underwent spine surgery due to spondylolisthesis or lumbar disc herniation in Imam Reza Hospital of Tabriz in 2022, in which surgical instruments were implanted or not, and during one year after the operation, due to the development of complications, they were referred again and were evaluated by CT or MRI. The sample size included all patients (at least 120 patients in each group) who underwent surgery for spondylolisthesis or lumbar disc herniation. The sampling method in this study was census. After entering the demographic information, history and information of the patients' files in the relevant checklists, the patients were divided into two groups, operated with or without instruments, and the frequency of short-term complications was compared between them. Results: In this study, among all the short-term complications caused by spondylolisthesis surgery, none of the variables of spondylolisthesis recurrence, collection, spondylodiscitis, spinal canal stenosis, pseudomeningocele and displacement of instruments were observed statistically significant differences between the two groups of studied patients with and without instrumentation (P>0.05). Also, in this study, among all the short-term complications caused by lumbar disc herniation surgery, none of the variables of lumbar disc herniation recurrence, collection, spondylodiscitis, spinal canal stenosis, pseudomeningocele and displacement of instruments were observed statistically significant differences between the two groups of studied patients with and without instrumentation (P>0.05).
