Abstract
Background
Lateral lumbar interbody fusion may be performed through lateral decubitus (LD-LLIF) or prone transpsoas (PTP) approaches. While PTP offers theoretical advantages related to single-position access and sagittal alignment, comparative data evaluating perioperative outcomes, complication profiles, and radiographic parameters remain limited. This study compares clinical outcomes, complications, and radiographic alignment between LD-LLIF and PTP, with additional subgroup analysis of staged versus single-stage LD-LLIF procedures.
Methods
A retrospective observational study was conducted at a single academic center. Adult patients undergoing LD-LLIF or PTP between August 2021 and March 2024 by fellowship-trained orthopaedic spine surgeons were identified. Demographics, comorbidities, operative parameters, radiographic measurements, and perioperative outcomes were collected. Subgroup analysis compared staged and single-stage LD-LLIF procedures. Statistical analysis utilized two-sided t-tests and chi-squared tests with significance set at p < 0.05.
Results
A total of 82 patients were included (LD-LLIF: 54; PTP: 28). Operative time was significantly longer in PTP compared to LD-LLIF (472.5 ± 204.5 vs. 266.8 ± 91.0 minutes, p < 0.001). PTP was associated with higher estimated blood loss (p = 0.056), shorter hospital stay (p = 0.050), and increased rates of dural tear (14.3% vs. 0%, p = 0.012) and transient postoperative hip flexor weakness (21.4% vs. 0%, p = 0.001). Radiographically, PTP demonstrated greater postoperative segmental lordosis (12.4 ± 4.5° vs. 10.4 ± 4.0°, p = 0.041) and Cobb angle correction (−0.8 ± 5.0° vs. −4.3 ± 5.9°, p = 0.009), with no significant differences in global lumbar or L4-S1 lordosis. In the LD-LLIF subgroup, staged procedures (n = 18) demonstrated longer operative time (292.9 ± 46.6 vs. 231.0 ± 123.7 minutes, p = 0.013), but complication rates were not significantly different compared to single-stage procedures (27.8% vs. 21.1%, p = 0.736).
Conclusion
Both LD-LLIF and PTP achieved effective radiographic correction with acceptable complication profiles. LD-LLIF and PTP may be used in the treatment of primary and revision lumbar spinal pathology. In our series, PTP was associated with longer operative time and higher neurologic complication rates. Staged LD-LLIF procedures increased operative duration without increasing complication rates. Further prospective investigation is warranted to optimize patient selection and evaluate long-term outcomes.
期刊介绍:
Seminars in Spine Surgery is a continuing source of current, clinical information for practicing surgeons. Under the direction of a specially selected guest editor, each issue addresses a single topic in the management and care of patients. Topics covered in each issue include basic anatomy, pathophysiology, clinical presentation, management options and follow-up of the condition under consideration. The journal also features "Spinescope," a special section providing summaries of articles from other journals that are of relevance to the understanding of ongoing research related to the treatment of spinal disorders.
