- W4254286872 abstract "Abstract ObjectiveDynesys stabilization (DS) is utilized to preserve mobility at the instrumental segments and prevent adjacent segment pathology (ASP) in clinical practice. However, the advantages of DS method remain controversial. This meta-analysis was to compare the radiographic and clinical outcomes between DS and instrumented fusion in patients with or without grade I spondylolisthesis at a minimum follow-up period of 2 years. MethodsWe conducted a comprehensive search of PubMed, EMBASE, Cochrane, and Web of Science databases for potentially eligible articles. Clinical outcomes were assessed in terms of surgical time, intraoperative blood loss, length of hospital stay, in-hospital complications, VAS and ODI scores, screw loosening and breakage, and reoperation. Radiographic outcomes were assessed in terms of postoperative range of movement (ROM) and disc heigh. Moreover, adjacent segment degeneration (ASDeg) and adjacent segment disease (ASDis) were evaluated. Data are expressed as risk ratio or standardized mean difference with the associated 95% confidence intervals. The meta-analysis was performed using RevMan 5.3 and STATA 15.1 software.ResultsFourteen studies with 1078 patients were included in the meta-analysis. The mean durations of follow-up ranged from 26.64 ± 5.16 months to 93.6 ± 16.5 months. The DS group was associated with significantly shorter surgical time, fewer intraoperative blood loss, shorter length of hospital stay, less in-hospital complications, lower postoperative VAS scores for low-back and leg pain than the fusion group ( P < 0.05). Moreover, the ROM at the stabilized segments of the fusion group decreased significantly ( P < 0.01) and that at the adjacent segments increased significantly compared with those of the Dynesys group ( P < 0.01). Additionally, the Dynesys group showed significantly less ASDeg than the fusion group ( P < 0.01) but showed no significant advantage over the fusion group in terms of preventing ASDis ( P = 0.33). Furthermore, the Dynesys group was insignificantly different from the fusion group in terms of ODI, screw loosening, screw breakage, surgical reoperation, and disc heigh at stabilized and adjacent segments ( P > 0.05).ConclusionDynesys stabilization showed satisfactory clinical outcomes and provided additional benefits in preserving the motion at the stabilized segments and limiting the hypermobility at the adjacent segments compared with fusion method. Dynesys stabilization represented a complementary choice in the treatment of degenerative spinal lumbar disease with or without grade I spondylolisthesis." @default.
