Case Reports
Upper-airway obstruction after short posterior occipitocervical fusion in a flexed position.
Case report. ⋯ An adequate fixation angle is necessary to avoid airway obstruction after an occipitocervical fusion, even for short upper cervical fusions, especially in patients with rheumatoid arthritis.
-
A total of 46 patients undergoing lumbar spine surgery for degenerative lumbar disease and presenting with drop foot were included in this retrospective study. ⋯ Palsy duration and preoperative strength were factors that most affected drop foot recovery following surgical intervention for spinal degeneration.

Retrospective case series with a control group. ⋯ Compared with conventional MRI, MRM affords more specific information for the presurgical diagnosis of symptomatic foraminal stenosis.

Comparative Study Clinical Trial
Total lumbar disc replacement: different results for different levels.
Prospective study analyzing midterm clinical results of total lumbar disc replacement (TDR) with ProDisc II performed at different lumbar motion segments. ⋯ The level and the number of lumbar disc replacements influence postoperative outcome significantly. Satisfactory outcome was achieved for monosegmental L4-L5 and L5-S1 disc replacement procedures with best results achieved following TDR at L4-L5. For bisegmental TDR, complication rates are significantly higher and inferior postoperative results are to be expected. The incidence of postoperative pain originating from facet and/or iliosacral joints is currently underestimated and will require further investigation.

Modified Delphi panel using Q-methodology. ⋯ Until definitive evidence is available, back disability prevention interventions will likely need to address multiple factors simultaneously and emphasize efforts to improve care provider reassurance. Consensus findings may vary depending on the panel. Research on nonoccupational participation, environmental factors at home, and reasons for discordant interpretation of evidence is needed.
