STUDY DESIGN: Retrospective cohort study OBJECTIVE.: To determine the independent effects of operative time and surgical invasiveness on perioperative outcomes after posterior spinal fusions for adult spinal deformity. SUMMARY OF BACKGROUND DATA: Morbidity is high after posterior fusions for adult spinal deformity. While previous reports have demonstrated an association between perioperative outcomes and the extent of correction and fusion (number of posterior levels fused, pelvic fixation, combined anterior-posterior fusion), no study has looked at the independent effects of the surgical invasiveness after controlling for operative time...

Lumbar fusion is a surgical procedure performed to eliminate painful motion in a spinal segment by joining, or fusing, two or more vertebrae. Although the surgery has a high rate of producing radiographic fusion, many patients report pain, functional disability, an inability to return to work, and prolonged opioid pain reliever use following the procedure. Using the biopsychosocial model of low back pain as a framework, this review of the literature describes the biological, psychological, and social factors that have been associated with these negative outcomes...

Intramedullary spinal cord tumors (IMSCTs) represent a rare entity, accounting for 4%-10% of all central nervous system tumors. Microsurgical resection of IMSCTs is currently considered the primary treatment modality. Intraoperative neurophysiological monitoring (IONM) has been shown to aid in maximizing tumor resection and minimizing neurological morbidity, consequently improving patient outcome. The gold standard for IONM to date is multimodality monitoring, consisting of both somatosensory evoked potentials, as well as muscle-based transcranial electric motor evoked potentials (tcMEPs)...

BACKGROUND AND IMPORTANCE: Tarlov cysts, also known as perineural cysts, have been described as meningeal dilations of the spinal nerve root sheath between the peri- and endoneurium at the dorsal root ganglion. Most often they are found in the sacrum involving the nerve roots. Normally asymptomatic, they have been reported to present with radiculopathy, paresthesias, and even urinary or bowel dysfunction. Sacral insufficiency has not been a well-documented presentation. CLINICAL PRESENTATION: The patient is a 38-year-old female who started to develop left low back pain and buttock pain that rapidly progressed into severe pain with some radiation down the posterior aspect of her left leg...
