Minimally invasive surgeries including endoscopic surgery and mini-open surgery are current trend of spine surgery, and its main advantages are shorter recovery time and cosmetic benefits, etc. However, mini-open surgery is easier and less technique demanding than endoscopic surgery. Besides, anterior spinal fusion is better than posterior spinal fusion while considering the physiological loading, back muscle function, etc. Therefore, we aimed to introduce the modified -mini-open anterior spine surgery- MOASS and to evaluate the feasibility, effectiveness and safety in the treatment of various anterior lumbar diseases with this technique. A total of 61 consecutive patients 46 female, 15 male; mean age 58.2 years from 1997 to 2004 were included in this study, with an average follow-up of 24–52 mean 43 months. The disease entities included vertebral fracture 20, failed back surgery 13, segmental instability or spondylolisthesis 10, infection 8, herniated disc 5, undetermined lesion for biopsy 4, and hemivertebra 1. Lesions involved 13 cases at T12–L1, 18 at L1–L2, 18 at L2–L3, 22 at L3–L4 and 11 at L4–L5 levels. All patients received a single stage anterior-only procedure for their anterior lumbar disease. We used the subjective clinical results, Oswestry disability index, fusion rate, and complications to evaluate our clinical outcome. Most patients 91.8% were subjectively satisfied with the surgery and had good-to-excellent outcomes. Mean operation time was 85 62–124 minutes, and mean blood loss was 136 minimal-250 ml in the past 6 years. Hospital stay ranged from 4–26 mean 10.6 days. Nearly all cases had improved back pain 87%, physical function 90% and life quality 85%. Most cases 95% achieved solid or probable solid bony fusion. There were no major complications. Therefore, MOASS is feasible, effective and safe for patients with various anterior lumbar diseases.
