1 Eurospine 2018 Barcelona Computed tomography analysis of L5-S1 fusion in Adult spinal deformity Comparison of whether spinopelvic fixation, ALIF vs PLIF, and cage design Jung-Hee Lee MD, Kyung-Chung Kang MD, Dong-Gune Chang MD, Tae-Jin Kim MD, Ki Young Lee MD, Won Ju Shin MD Dept of Orthopedic Surgery, Kyung Hee University, Seoul, Korea
2 Introduction In adult spinal deformity,,, Fusion to L5 : instability L5-S1 - back pain, sagittal imbalance, radiculopathy,, Fusion to S1 : pseudarthrosis - debilitating pain, sagittal decompensation - pseudarthrosis : sacropelvic fixation, interbody fusion, BMP Important to achieve optimal sagittal balance - Interbody fusion L5-S1 Horton (1996), Spine Kim (2003), KSSS Eck (2001), Spine Kim (2006), Spine Edwards (2005), Spine Ondra (2006), Spine Polly (2006), Spine Maeda (2010), Spine Purpose of this study Achieving a solid fusion of L5-S1 - risk factor analysis is important Analyze the CT of L5-S1 fusion in ASD patients who underwent surgical correction and evaluate the surgical options - whether spinopelvic fixation - S2AI vs conventional iliac fixation - ALIF vs PLIF - cage design (metal vs PEEK) - long vs short fusion
3 Materials & Methods Demographics & inclusion criteria Adult spine deformity with sagittal imbalance who underwent surgical correction 78 females Age : 70.5 years (mean) Interbody fusion L5-S1 Minimum f/u 2 years Definition and grade of fusion Analysis by CT Grade 1: no fusion Grade 2: in disk space, ossification (+) not continuous with both endplates Grade 3: bridging < 50% of the endplates Grade 4: bridging > 50% of the endplates Grade 3 & 4 : solid fusion Surgical methods UIV T10 57 T12 2 L1 4 L2 6 L3 6 L4 3 LIV : S1(n=78) Fused segments : av. 6.9 seg. Sacropelvic fixation iliac screw S2AI (n=12) (n=36) Anterior vs Posterior ALIF PLIF Without BMP (n=63) (n=15) ALIF : allo + DBM PLIF : auto + DBM

10 Discussion ASD in elderly patients 87.2% union rate in CT metal cage > PEEK cage - maximized contact surface with bone sacropelvic fixation > no fixation - iliac screw : conventional, anatomic, S2AI - S2 alar screw Limitation of this study small patients group (78 pts) no BMP ALIF allobg + DBM exact comparison PLIF autobg + DBM
11 Conclusion Significance of this study 87.2% union rate of L5-S1 in CT Union rate - sacropelvic fixation vs no fixation - metal cage vs PEEK cage no relationship with - ALIF vs PLIF - long vs short fusion - S2AI vs iliac screw Halo sign of S1 or iliac screw on X-ray - no correlation with nonunion of L5-S1
