In Brief:
Pseudarthrosis is a feared complication following spinal fusions. In 220 patients treated with minimally invasive antepsoas-lumbar fusions, arthrodesis was evaluated using follow-up computed tomography scans. Successful fusion was noted in 96.4% of operated patients and 98.3% of the fused levels. Nonetheless, smoking history, multilevel fusions, and surgery at L5-S1 remain considerable risk factors.
