Background: The surgical treatment of Symptomatic Segmental Lumbar Disc Disease-SSLDD is undergoing scrutiny by health care providers, governmental, and commercial insurance carriers. We retrospectively studied 114 adult patients treated surgically by the MAST/TLIF- Minimal Access Surgical Technology/Transforaminal Lumbar Interbody Fusion for a minimum of 24 months after surgery. Outcome Measures: Patient hospitalization time, operative blood loss, surgical time, fluoroscopic time, return to work time, sex, age, implant type, segmental lordosis, disc height, spondylolisthesis reduction, fusion rate, Oswestry scores, and complications were studied. Study Design/ Setting: 114 adult patients were treated. All patients exhibited focal, single-segment, lumbar, pain-producing disease. All patients participated in six weeks of non-surgical treatments. Patient Sample: 114 patients were treated between January 2002 and December 2004. Diagnoses included spondylolisthesis, failed discectomy, axial interbody collapse, segmental stenosis, massive disc herniation, and failed posterolateral fusion Methods: A percutaneous rod-pedicle screw system, 26mm.tubular tissue retraction system, and an intra-discal cages were used fuse each segment. Results: Average hospitalization was thirteen hours. Average blood loss was 159cc. Average radiation exposure was 169 seconds. Average surgery time was 154 minutes. 90% of all patients returned to work within 10 weeks. Narcotic usage was cut by 77%. Oswestry scores improved by 50%. Conclusions: MAST/TLIF lumbar fusion surgical procedure demonstrates a low failed fusion rate, speedy return to normal work, 77% reduction in narcotic dependency, no adjacent level degeneration, dramatic reduction in hospitalization services, and no infections. MAST/TLIF lumbar fusion procedure is a prudent treatment option for symptomatic, segmental, lumbar, disc disease-SSLDD.
