Retrospective study. ⋯ 4.

A case report. ⋯ Electrophysiological monitoring might be useful when intraoperative anatomical findings of the hemodynamic structure are inadequate. Moreover, in our case, intraoperative changes in motor evoked potentials indicated the risk to occlude one of posterior SAs, although it is said that posterior circulation of spinal cord has ischemic tolerance.

Randomized Controlled Trial
Five-year Follow-up of a Prospective, Randomized Trial Comparing Two Lumbar Total Disc Replacements.
This was a prospective, randomized, controlled, multicenter study. ⋯ This prospective, randomized study comparing two TDRs found no significant differences in outcomes during 5-year follow-up. Both provided statistically significant improvements by 6 weeks that were maintained. This results support other studies. Serum ion levels in TDR patients were well below the recommended threshold levels to merit monitoring.
