Abstract
ABSTRACT Objective: to investigate the frequency of recurrent lumbar disk herniation (rLDH) and evaluated risk factors of rLDH in Russian population. Methods: this was a retrospective clinical study. From January 2015 to March 2022, 218 patients having single-level LDH at three institutes were included in this clinical study and who were then observed for a minimum of 5 years postoperatively. All the patients or relatives gave informed consent to participate in this study. The levels of disk herniation were L4-L5 in 132 cases (60.5 %), and L5-S1 in 86 cases (39.4 %). Results: The rLDH group was composed of 31 male and 12 female, whose ages ranged from 18 to 57 years (34.8±9.5 years). The non-rLDH group was composed of 97 male and 78 female, whose ages ranged from 19 to 73 years (47.5±9.8 years). According to the constructed binary logistic model, body mass index (p=0.021), current smoking (p=0.017), stage of disk degeneration (p=0.043), facet tropism (p=0.037), disk height index (p=0.018) and apparent diffusion coefficient (p=0.009) are significantly associated with incidence of rLDH. Conclusions: patients with these risk factors should be paid more attention for prevention of rLDH. Level of Evidence III; Retrospective Study.
