Methods Articles about anatomical advantages and the complications of OLIF in patients with ASD were searched in CNKI, WanFang, WeiPu, and PubMed databases before December 2022. "斜外侧腰椎椎间融合术" "成人脊柱畸形" "脊柱微创手术" "oblique lumbar interbody fusion" "adult spine deformity" and "minimally invasive spine surgery" were used as key words, and the clinical effects and capability of OLIF for correction and balance restoration were explored. A total of 98 articles were searched, and 38 were finally included after articles that did not conform to the content, no available full text, were repeated studies, or had design defects were excluded. Results The procedure corridor of OLIF is between the aorta and psoas. OLIF achieves indirect neural decompression, preventing the destruction of the posterior muscular ligament complex and lowering surgical trauma, risk of bleeding, and infection. For patients with ASD, OLIF can provide partial correction to coronal and sagittal deformity, but it has limitation to correction. By inserting a lordotic cage and planning the reasonable cage area, OLIF can effectively correct lumbar lordosis and restore the trunk balance, producing a good clinical effect. When OLIF is used to treat adult spinal malformations, it damages the lumbar sympathetic chain, lumbar plexus, lumbar segmental arteries, iliac vessels, and endplates during operation owing to its special surgical approach. Conclusion OLIF is one of the effective and minimally invasive treatments for ASD and can effectively alleviate neurological deficits, restore trunk balance, reduce surgical trauma, and lower intraoperative bleeding, perioperative complications, and off-bed time. Surgical indications should be controlled because of its relatively limited capability for correction and balance restoration. Bone density, CT, MRI, and other related examinations should be improved before surgery. During an operation, surgeons should prevent damage to the peripheral vascular system and nerves to reduce surgical complications.
