Blood transfusions in spine surgery are shown to be associated with increased patient morbidity. The association between transfusion performed using a liberal hemoglobin (Hb) trigger-defined as an intraoperative Hb level of ≥10 g/dL, a postoperative level of ≥8 g/dL, or a whole hospital nadir between 8 and 10 g/dL-and perioperative morbidity and cost in spine surgery patients is unknown and thus was investigated in this study. ⋯ Transfusion using a liberal trigger is associated with increased morbidity, even after controlling for possible confounders. Our results suggest that modification of transfusion practice may be a potential area for improving patient outcomes and reducing costs.

Minimally invasive spine surgery has become increasingly popular in clinical practice, and it offers patients the potential benefits of reduced blood loss, wound pain, and infection risk, and it also diminishes the loss of working time and length of hospital stay. However, surgeons require more intraoperative fluoroscopy and ionizing radiation exposure during minimally invasive spine surgery for localization, especially for guidance in instrumentation placement. In addition, computer navigation is not accessible in some facility-limited institutions. ⋯ This method avoids lateral shots of fluoroscopy during screw placement and thus decreases the operation time and exposes surgeons to less radiation. At the same time, compared with the computer-navigated procedure, it is less facility-demanding, and provides satisfactory reliability and accuracy.

Prevertebral soft tissue swelling (PSTS) after anterior cervical spine surgery (ACSS) has been regarded as one of the critical complications that cause airway obstruction. Still, however, no research has dealt with how PSTS returns to presurgery status after ACSS; most recommendations are being performed without information about its natural course, focusing on acute-phase swelling after surgery. ⋯ It is necessary to pay attention to PSTS and patient conditions after ACSS for at least 1 to 6 months postsurgery, depending on surgical method and operation levels.

Lumbar epidural corticosteroid injections (LECIs) are frequently used in the treatment of lumbar intervertebral disc herniation with radiculopathy and lumbar spinal stenosis. Although widely used, their effect on the outcomes and complications of subsequent surgery is unclear. Postoperative infection can be a morbid complication following spine surgery, and recent literature has suggested that the risk may be increased in patients undergoing lumbar spinal surgery who had previously received LECIs. ⋯ The results of this study suggest that within the MHS, preoperative LECIs do not significantly increase the risk of postoperative infection after single-level lumbar decompression. If a difference does exist, it is likely small.

Several prognostic studies looked for an association between the degree of spinal cord injury (SCI), as depicted by primary magnetic resonance imaging (MRI) within 72 hours of injury, and neurologic outcome. It was not clearly demonstrated whether the MRI at any time correlates with neurologic prognosis. ⋯ From our study, 2-3 days after injury, a significant relationship was observed between the vertical diameter of T2 high-intensity area and the neurologic prognosis at discharge. Zero to 1 day after injury, the relationship between the vertical diameter of T2 high-intensity area and the neurologic prognosis at discharge was weak. Neurologic prognosis is more correlated with MRI after 2-3 days after the injury. If the vertical diameter of T2 high-intensity area was <45 mm, the patients were able to walk with or without a cane at discharge. T2 high-intensity changed area can reflect the neurologic prognosis in patients with CSCI.
