Abstract
OBJECTIVE
This study aimed to evaluate the clinical efficacy and safety of S2-alar-iliac (S2AI) and iliac screw (IS) techniques in treating lumbosacral spondylodiscitis.
METHODS
Between January 2020 and January 2022, 28 patients suffering from lumbosacral spondylodiscitis underwent lumbosacral fixation and were divided into the IS group (14 patients) and the S2AI group (14 patients). Surgical details, demographic characteristics, preoperative and postoperative Oswestry Disability Index, visual analog scale, and complications were analyzed.
RESULTS
Twenty-eight patients were included in this study, including 14 patients treated with IS and 14 patients treated with S2AI. The 2 groups were similar in sex, age, follow-up period, total drainage volume, hospitalization stay, and fusion time. (P > 0.05) The estimated blood loss and surgical time of S2AI during surgery were significantly lower than those of IS. (P < 0.05) The visual analog scale and Oswestry Disability Index scores significantly improved in both groups from preoperative to the last follow-up. Sacroiliac joint pain was found in both groups in the follow-up period, but the incidence was not significantly different (P = 0.663). Compared with the IS approach, the incidence of symptomatic screw prominence was lower in the S2AI group, but the difference was not significant. (P = 0.088).
CONCLUSIONS
S2AI, as well as IS techniques, can achieve promising results for reconstructing lumbosacral stability in spondylodiscitis. In addition, the S2AI technique can also reduce surgical trauma and operation time.
