We sought to evaluate the safety and efficacy of topical administration of tranexamic acid (TXA) in high-risk patients undergoing posterior lumbar interbody fusion (PLIF) surgery. ⋯ In single-level PLIF surgery, topical administration of TXA could significantly reduce total blood loss, visible blood loss, postoperative drainage, removal time of drainage tube, and LOS without increasing the risk of thromboembolic events in high-risk patients with prior histories of thrombosis.

The current study seeks to examine the association between chronic opioid use and postoperative outcomes for patients undergoing anterior cervical discectomy and fusion (ACDF) and posterior lumbar fusion (PLF). ⋯ Our analysis using a national administrative database showed that opioid dependence may be associated with worse economic outcomes for patients undergoing ACDF and PLF.

To evaluate prevalence and prognosis of postoperative coronal imbalance (CIB) and factors related to its onset and spontaneous improvement in patients with Lenke 5C adolescent idiopathic scoliosis who underwent selective thoracolumbar-lumbar fusion. ⋯ Although CIB was frequently detected in the early postoperative period after selective thoracolumbar-lumbar fusion, it mostly corrected spontaneously. Relatively younger age at surgery and less flexible lumbosacral curve may be related to postoperative CIB, and greater changes of LIV disc angle may be associated with spontaneous improvement of CIB.

We performed a retrospective cohort study to investigate the prevalence of and risk factors for asymptomatic spondylotic cervical spinal stenosis (ASCSS) in the setting of lumbar spinal stenosis (LSS). ⋯ Our findings suggest that an LLA >35.85° and a DCSA <84.50 mm2 are risk factors for the development of ASCSS. For LSS patients with an enlarged LLA and reduced DSCA, a whole spinal magnetic resonance imaging examination should be performed.

We performed a fine white fiber dissection to demonstrate the extensive connections of the corpus callosum. ⋯ The corpus callosum was found to have intricate connections with all the lobes of the cerebral hemispheres, including the insular region and the limbic and paralimbic areas. Based on the course and traverse of the callosal fibers, a transverse incision in the corpus callosum should be preferred when performing a callosotomy to access intraventricular lesions as this splits the callosal fibers instead of transecting them. The analysis of the course of the callosal radiations enhances understanding of the growth pattern of primary corpus callosal gliomas and helps to design a safe surgical strategy.
