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.

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.

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.

A biomechanical investigation using a human cadaver, multisegmental lumbosacral spine model. ⋯ The placement of 2 small interbody cages posterolaterally tended to result in higher failure loads than central cage placement, although the results were not statistically significant. It is noteworthy that cage placement in any position resulted in a less stiff construct in compression than with an intact disc.

Survey-based descriptive study. ⋯ Variations in surgical approach to lumbar degenerative diseases may depend on a patient's clinical condition. This study found strong agreement in the approach to lytic spondylolisthesis but significant variation for other degenerative conditions of the lumbar spine. In addition, recommendation for fusion and instrumentation varied with surgeon age and training background. Previously documented geographic variations may result in part from a lack of consensus on appropriate treatment techniques for specific lumbar degenerative conditions, as well as surgeon-specific factors.
