165 What Is the Effect of Open vs Percutaneous Screws on Complications Among Patients Undergoing Lateral Interbody Fusion for Adult Spinal Deformity?

RESULTS: Of 420 patients that met inclusion criteria, 165 had complete data. One hundred thirty-seven were available for analysis after excluding 3 column osteotomies and 76 remained after propensity matching (38 cMIS and 38 HYB). There were no differences in demographics, number of levels instrumented (6.8 HYB vs 6.1 cMIS; P = .622), and pre- and postoperative radiographic results. HYB had significantly longer OR time (623 vs 490 minutes; P = .015) and larger expected blood loss (1396 vs 637; P = .001). 55.3% of HYB vs 44.7% cMIS patients experienced at least 1 COMP (P = .359). cMIS patients had significantly fewer neurological (P = .044), operative (P = .005), and minor (P = .034) COMPs. Reoperation was similar between groups (28.9% HYB, 26.3% cMIS). The most common COMP for cMIS was radiographic (n = 10; 6 with pseudoarthrosis) and neurological for HYB (n = 11; 8 with radiculopathy). Both groups saw improvement from pre- to postoperative Oswestry Disability Index, visual analog scale (VAS) back and leg (all P < .05); however, cMIS had a greater reduction in VAS leg (P = .002).
