Article Synopsis
- The study aimed to evaluate how reliable cervical sagittal alignment measurements are when comparing upright radiographs to MRI in adults undergoing surgery for cervical spondylotic myelopathy.
- Researchers found that while the correlation of the C2-C7 sagittal angle was high between the two imaging methods, cervical sagittal vertical axis (SVA) and T1 tilt measurements varied significantly based on patient positions.
- The conclusion emphasized that upright radiographs are preferable for assessing global sagittal alignment when planning specific cervical surgeries, as MRI does not accurately reflect the alignment in an upright position.
Background Content: Cervical laminoplasty (LP) and laminectomy and fusion (LF) are commonly used surgical techniques for cervical spondylotic myelopathy (CSM). Several recent studies have demonstrated superior perioperative metrics and decreased overall costs with LP, yet LF is performed far more often in the United States.
Purpose: To determine the percentage of patients with CSM who are radiographically candidates for LP.
Background Context: Laminectomy with fusion (LF) and laminoplasty (LP) are commonly used to treat cervical spondylotic myelopathy (CSM). The decision regarding which procedure to perform is largely a matter of surgeon's preference, while financial implications are rarely considered.
Purpose: We aimed to better understand the financial considerations of LF compared to LP in the treatment of CSM.
Objective: To evaluate the correlation between postoperative hyperglycemia and surgical site infection among patients who underwent primary instrumented spinal fusion surgery.
Patients And Methods: We collected data on all eligible patients treated at our institution over the course of 2005-2017. We defined serum hyperglycemia using a primary threshold of serum glucose ≥140 mg/dL and used ≥115 mg/dL as a secondary test.
Study Design: Retrospective cohort study.
Objective: To evaluate the impact of incidental durotomy during spine surgery on the development of delirium in patients aged 65 and older.
Summary Of Background Data: Delirium after spine surgery has been shown to increase the risk of adverse events, including morbidity and readmissions.
Study Design: Retrospective cohort study.
Objective: To assess whether administration of prophylactic vancomycin, in addition to cefazolin decreased revision surgeries for postoperative infection (SSI) as well as the need for revisions overall.
Summary Of Background Data: In 2010 our institution implemented an antibiotic prophylaxis regimen consisting of intravenous vancomycin and cefazolin that applied to all patients receiving surgical implants.
