Purpose: To describe the clinical outcomes and complications in a consecutive series of extreme lateral interbody fusion cases.
Methods: Retrospective cohort review of 97 consecutive patients from three centers with minimum 6-month follow-up (mean 12 months). Functional status was evaluated by preoperative and last follow-up Oswestry Disability Index score. Leg and back pain were evaluated by visual analog scales. Complications were recorded and permanent complications and neurological impairment was actively investigated at last follow-up.
Results: No permanent neurological impairment, vascular or visceral injuries were observed. Transient neurological symptoms presented in 7% of cases, all resolved within 1 month from surgery. Transient thigh discomfort was observed in 9%. Clinical success was recorded in 92% of cases.
Conclusions: Extreme lateral interbody fusion is a safe and effective technique for anterior interbody fusion.
