RESUMEN

STUDY DESIGN: Retrospective study of prospectively-collected data.OBJECTIVES: To evaluate the radiological outcomes of direct lateral lumbar interbody fusion (DLIF).SUMMARY OF LITERATURE REVIEW: DLIF, as a minimally invasive spinal surgical procedure, is useful for degenerative spinal diseases. However, few reports have evaluated the clinical and radiological outcomes of DLIF in Korea.MATERIALS AND METHODS: We analyzed 44 patients who underwent DLIF at our hospital from September 2015 to September 2017. Of these patients, 89 segments were included in this study. We measured preoperative and postoperative radiological values including the disc height, central canal area, height of the foramen, and segmental sagittal angle on magnetic resonance imaging. We also measured patients' visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores as clinical parameters.RESULTS: Statistically significant improvements were found in the height of the left and right foramina (20.8% and 25.6%, respectively), the height of the intervertebral discs (86.0% and 84.3%, respectively), the cross-sectional area of the central nervous system (33.1%), lumbar lordosis, and the lumbar segmental angle (2.7° and 8.7°, respectively) after surgery. The VAS and ODI scores also showed significant improvements (65.7% and 67.7%, respectively) when compared with the preoperative level.CONCLUSIONS: DLIF was found to be effective for the treatment of diseases such as foraminal stenosis, degenerative spondylolisthesis, and adjacent segment diseases through indirect neuro-decompression of the bilateral foramina and central vertebrae.

RESUMEN

Direct lateral lumbar interbody fusion (DLIF) has been introduced as an effective new thoracolumbar fusion technique for patients with degenerative lumbar diseases. DLIF associated with easy-to-learn, high fusion rate, improved restoration of spinal alignment, and early patient mobilization due to minimally invasive nature. However, ipsilateral L2–L5 nerve root irritation and injury are well-known complications. However, damage to the contralateral nerve root has been rarely reported and, to the best of our knowledge, there have not been any reports about contralateral nerve root injury after DLIF in Korea. Thus, we report a case of contralateral nerve root compression due to osteophyte from the lower endplate of the vertebral body and position of intervertebral cage after DLIF.
