Preliminary Clinical and Radiographic Outcomes of the Prone-Angled Transpsoas Approach for Lateral Lumbar Interbody Fusion: A Consecutive Clinical Series.
Year: 2026
Type: article
Abstract: BACKGROUND AND OBJECTIVES: The prone-angled transpsoas (PAT) approach is a novel lateral lumbar interbody fusion technique that combines the workflow and sagittal alignment advantages of prone positioning with a navigated angled anterior-to-psoas trajectory. Although technical feasibility has been described, clinical outcomes remain limited. This study reports the preliminary clinical, radiographic, and perioperative outcomes of PAT for degenerative lumbar pathology. METHODS: -tests with available paired observations. RESULTS: < .001). Transient iliopsoas pain occurred in 17.1% of patients, and transient quadriceps weakness in 5.7%, with resolution by 6 weeks. Four patients (11.4%) underwent subsequent reoperation. No permanent neurological deficits, vascular injuries, cerebrospinal fluid leaks, or pneumothoraxes occurred. CONCLUSION: In this preliminary clinical series, PAT was associated with significant improvements in pain, disability, and LL. Transient approach-related symptoms occurred, whereas no permanent neurological or vascular injuries were observed. These early findings support the feasibility of PAT and warrant larger comparative studies to characterize its safety, efficacy, and durability relative to established lateral lumbar interbody fusion approaches.
