Abstract: ObjectiveTo evaluate the surgical techniques and 2-year follow-up results of Mast Quadrant-assisted modified transforaminal lumbar interbody fusion (TLIF).MethodsFrom September 2006 to October 2008,54 patients with single-level lumbar degeneration disease were treated by Mast Quadrantassisted modified TLIF.Under the guidance of C-arm,the Mast Quadrant's retractor was placed and the lower articular process of the upper vertebrae and 1/2-2/3 of the lamina,flavum ligament and hyperplastic cohesive part of the lower articular process were removed,the nerve roots and the central canal were decompressed.After cleaning up intervertebral disc space,bone grafting and pedicle screw fixation were achieved.Visual analogue scale(VAS) and Oswestry disability index(ODI) results,as well as the fusion rate at the last follow-up were analyzed.ResultsAll patients were treated by Mast Quadrant-assisted modified TLIF,in which 51 patients were followed up for 2 years.An average operating time was(178.7±63.2) min,and an average blood loss was (224.2±136.5) ml; an average postoperative drainage loss was (117.2±91.4) ml,and an average postoperative stay was(5.8±3.6) d.There were statistic significances between pre- and post-operative ODI and VAS scores,respectively.At last follow-up,51 patients were achieved radiographic fusion without internal fixation failure and other complications.ConclusionMast Quadrant-assisted modified TLIF had a good vision,was relatively safe and easy to be acceptable by surgeons,and which had a good clinical results for the patients with single-level lumbar degenerative disease.
