OBJECTIVE Efforts to examine the value of care-combining both costs and quality-are gaining importance in the current health care climate. This thrust is particularly evident in treating common spinal disease where both incidences and costs are generally high and practice patterns are variable. It is often challenging to obtain direct surgical costs for these analyses, which hinders the understanding of cost drivers and cost variation. Using a novel tool, the authors sought to understand the costs of posterior lumbar arthrodesis with interbody devices...

BACKGROUND AND STUDY AIM:  Cortical screws were proposed as an alternative to the traditional pedicle screws. Diverse experimental results support the biomechanical superiority of cortical screws compared to pedicle screws. Laminectomy is often part of multilevel lumbar surgeries. Laminectomy might weaken the medial bony edge at the entry of the divergently oriented screw and, thereby, the screw purchase. This study investigated the biomechanical strength of lumbar cortical screw after laminectomy...

Background: Few studies in the literature discuss operative positioning for lumbar surgery precipitating acute cauda equina syndromes (CES). Case Description: A 56-year-old male with a large L2-3-disc herniation was placed prone on a Jackson table. He immediately lost all motor and sensory evoked potentials. Signals returned to the baseline when surgery was aborted, and he was returned to the supine position. However, potentials were again lost when he was repositioned prone, following which the surgeons proceeded with surgical decompression with a good outcome...

BACKGROUND CONTEXT: Postoperative urinary retention (POUR) is a very common postoperative complication of all surgeries (5%-70%) that may lead to complications such as urinary tract infection (UTI), bladder overdistension, autonomic dysregulation, and increased postoperative length of stay (LOS). Within the field of spine surgery, the reported incidence rate of POUR is highly variable (5.6%-38%). Lack of clear stratification of surgical level, spinal pathology, and inadequate sample size are major limitations of available studies concerning POUR following spine surgery, which may lead to inconsistency in the incidence of POUR and the ability to model its occurrence and consequences...

OBJECTIVE: Some patients experience failed back surgery syndrome after lumbar spine surgery. We report the effect of additional treatments for paralumbar spine and peripheral nerve diseases addressing residual symptoms after surgery. METHODS: We enrolled 74 patients (59 men and 15 women; mean age 62.9 years) who had undergone lumbar posterior decompression surgery. Mean follow-up after initial surgery was 26.2 months (range, 13-48 months). We subsequently diagnosed paralumbar spine diseases, including superior cluneal nerve entrapment neuropathy with (n = 3) or without gluteus medius muscle pain (n = 4) and gluteus medius muscle pain alone (n = 5), and peripheral nerve diseases, including peroneal nerve entrapment neuropathy (n = 4) and tarsal tunnel syndrome (n = 1), based on persistent or recurring clinical symptoms and nerve block effects...

BACKGROUND: Adult tethered cord syndrome is a rare neurologic disorder that classically presents with back or leg pain, weakness, and urinary dysfunction. Spinal cord tethering has been associated with acquired Chiari malformations. Whereas the effects of tethered cord release on Chiari malformation symptoms have been described previously, we report an unusual case of acquired tethered cord syndrome following Chiari decompression. CASE DESCRIPTION: We report a 68-year-old man with a history of distant T12-level spinal cord injury and 2 weeks of progressive bilateral lower extremity weakness...
