In vitro analysis. ⋯ 3D-pTi provides a scaffold for bone formation that structurally mimics cancellous bone and improves hMSC adhesion and proliferation compared to 2D-Ti and PEEK.
-
A prospective, multicenter study. ⋯ Tc-MEP alert during position change is an important sign of spinal cord injury due to alignment change at the upper thoracic spine. Tc-MEP monitoring before supine-to-prone position change was necessary to prevent spinal cord injury in surgeries for T-OPLL.
-
Case-control study. ⋯ While infrequent, patient complaints against orthopedic spine surgeons are most related to access and availability. The rate of malpractice events varies widely between surgeons.
-
A retrospective study. ⋯ Among commercially insured patients who received outpatient spine surgery, the incidence of ED visits during the 90-day postoperative period was ~9%. Our results indicate opportunities for improved postoperative care planning after outpatient spinal surgery.
-
A prospective analysis. ⋯ Screw stimulation with threshold hunting algorithm has a distinct advantage over the time-consuming insulated pilot hole stimulation, allowing an uninterrupted flow of the surgery. The present findings have documented practical usefulness and reliability of CMAP monitoring using direct stimulation of the PPS assembled to uninsulated extender sleeve.
