Type 2 sclerotic Modic change affect fusion result in patients undergoing PLIF with pedicle screw instrumentation: a retrospective study

Abstract Background Bony fusion rate was significantly lower in patients with type 3 Modic change than normal endplates. It is not known whether there are relevant differences efficiency among 2 sclerotic or non-sclerotic change, no change. Methods A retrospective study contained 196 lumbar segments 123 subjects undergoing posterior interbody (PLIF) pedicle screw instrumentation (PSI) to assess the effect of on efficiency. These endplates were allocated into groups A, B, and C, according their changes. Group had endplate sclerosis. B without C neither nor The presence determined by magnetic resonance imaging (MRI). Endplate sclerosis detected computed tomography (CT) before operation. We collected CT data months more 24 after operation bony fusion. Results Incidences 58.8% group 95.0% 94.3% C. either There significant difference between Thus, a PLIF PSI. Conclusion Type could be an important factor that affects solid may help diagnose inform choice best site for spinal
