Comparative Study
Modified Marmot operation versus spinous process transverse cutting laminectomy for lumbar spinal stenosis.
Retrospective comparative cohort study. ⋯ The MM operation was less invasive and produced superior clinical outcomes compared with laminectomy involving exposure of the PVM.
-
This was a cross-sectional study. ⋯ The modified LEFS had satisfactory psychometric properties in patients with LBP and could serve as a supplementary outcome measure to assess their activity limitations.
-
Retrospective clinical and radiographical review. ⋯ Routine postoperative radiographical surveillance has minimal value for asymptomatic patients after anterior lumbar interbody fusion with or without posterior fusion. Obtaining a limited number of postoperative films of these patients in the absence of clinical symptoms or risk factors could significantly reduce health care costs and unnecessary radiation exposure.
-
Retrospective case series. ⋯ To the authors' best knowledge, this study constitutes the largest series of this sort to date, with regard to both sample size and study period. The present data indicate a decreasing proportional trend over time for SDs, MDs, and anterior TP, which can be considered a representation of an institutional learning curve during a 6-year time period of performing LLIF.

Retrospective review. ⋯ LMWH prophylaxis seems to carry a very low hemorrhage risk when started 24 to 36 hours after spine surgery. Larger, prospective studies are needed to assess the safety of early delayed LMWH administration more definitively. Even with aggressive prophylaxis, patients undergoing fusion or multilevel laminectomy for degenerative disease are at significant risk for VTE.
