Comparison of Anterior versus Posterior Fixation in Traumatic Subaxial Cervical Spine Subluxation in Terms of Intraoperative Blood Loss, Surgical Time, and Length of Hospital Stay: A Prospective Observational Study

Abstract

Objective The aim of this study was to compare the outcome of anterior versus posterior fixation for traumatic subaxial cervical spine subluxation in terms of mean intraoperative blood loss, surgical time, and length of hospital stay. Materials and Methods A prospective observational study was conducted from August 25, 2022 to August 24, 2023 at the Department of Neurosurgery, Punjab Institute of Neurosciences, Lahore, Pakistan, including 60 patients (30 in each group) fulfilling the inclusion criteria. Group A had anterior cervical fixation, while group B underwent posterior cervical fixation. Patients were monitored for intraoperative blood loss, surgical time, and length of hospital stay. All the results were collected and recorded on a proforma. Results The mean age of the patients in group A was 45.40 ± 3.75 years and that in group B was 45.50 ± 4.13 years. In all, 48.8% (n = 21) were males and 52.9% (n = 9) were females in group A, while 51.2% (n = 22) were males and 47.1% (n = 8) were females in group B. The mean intraoperative blood loss was 71.60 ± 0.77 mL in group A and 101.76 ± 0.85 mL in group B. The mean surgical time was 72.73 ± 0.98 minutes in group A and 94.73 ± 0.58 minutes in group B. The mean length of hospital stay was 7.63 ± 0.55 days in group A and 12.80 ± 0.71 days in group B. Conclusion It was concluded that the anterior approach is better than the posterior approach for traumatic subaxial cervical subluxation spine in terms of low blood loss, less surgical time, and reduced hospital stay.
