Abstract
The main difference between prone and lateral surgery is that the patient’s position is changed from lateral decubitus to prone, which may work around the three principal difficulties of the standard lateral approach. The prone transpsoas (PTP) technique enables single-position surgery with more familiar patient positioning, which improves lumbar lordosis and lengthens the psoas muscle, pushing it posteriorly. Therefore, this study aimed to examine the clinical and surgical outcomes of the prone transpsoas procedure. This was a retrospective case series in which patients with up to two levels of lateral lumbar interbody fusion in the prone decubitus position for degenerative diseases were included. The outcomes of interest were classified as surgical or clinical. According to the variable distribution, Kruskal–Wallis or one-way ANOVA was used to assess variance across all groups, and the t-test or Wilcoxon test was used to examine intragroup variances. The statistical significance level was set at p < 0.05. Thirty-nine patients participated in the trial. The average operating time was 166 min (± 79 min), and the average blood loss was 182 mL (± 151 mL). The median length of hospital stay was 1 day, with an interquartile range of 1.25 days. All clinical outcomes significantly improved at 1–3, 6–12, and 24–36 months compared to baseline. There was one intraoperative (2.5%) and two post-operative complications (5.1%). According to the authors’ case experience, PTP is a safe, practical, and reproducible procedure capable of treating a wide spectrum of degenerative disorders.
