Segmental arteries were interrupted bilaterally at up to three levels to study the influence on spinal cord blood flow (SCBF) and function in dogs. ⋯ Interruption of bilateral segmental arteries at three levels did not damage spinal cord function in dogs, suggesting that in patients, preoperative embolization at three levels to reduce blood loss during surgery for spinal tumors would not compromise spinal cord function.

Observational study conducted within a randomized clinical trial. ⋯ Patient satisfaction may confer small short-term clinical benefits for low back pain patients. Long-term perceived improvement may reflect, in part, perceived past improvement as measured by satisfaction.

Prospective, longitudinal minimum 2-year follow-up. ⋯ Our preliminary data on multisegmental ProDisc lumbar total disc arthroplasty appear to be a safe and efficacious treatment method for debilitating lumbar spondylosis without significant facet arthropathy. In our select (non-Workers Compensation and/or medical legal) cohort of patients, we demonstrate a patient satisfaction rate of 93%. Careful and appropriate patient selection is essential in ensuring optimal surgical outcomes.

Prospective, longitudinal minimum 2-year follow-up. ⋯ Single-level Prodisc lumbar total disc arthroplasty is a safe and efficacious treatment method for debilitating lumbar discogenic LBP. Significant improvements in patient satisfaction and disability scores occurred after surgery by 3 months and were maintained at the 2-year follow-up. No device-related complications occurred. Patients with severe to moderate disc height loss as well as those with symptomatic posterior anular defects with minimal disc height loss achieve functional gains and significant pain relief. Careful and appropriate patient selection is essential in ensuring optimal surgical outcomes.

We describe our surgical experience to remove osteoid osteomas and osteoblastomas of the occipitocervical junction. In this location, vertebral artery vicinity requires special consideration. ⋯ Removal of osteoid osteomas and osteoblastomas of the occipitocervical junction is safe and efficient. Stability is preserved if more than half the joints are preserved with a proper surgical approach that minimizes bone resection.
