In recent years, the number of publications on lumbar intercorporeal fusions has increased considerably. Since 1930, Capener, who was the first person to describe an earlier approach to the management of spondylolisthesis, to what we know today as minimally invasive surgeries. All this has led to surgery for lumbar intracorporal fusion has become a common technique to treat different pathologies such as spondylolisthesis, degenerative disc disease, recurrent disc herniations, pseudoarthrosis and spinal deformity in the sagittal and coronal plane. Historically, approaches for anterior interbody fusion have been characterized because they allow direct access to the intervertebral disc, with a higher potential fusion rate, compared to other techniques; However, the presence of certain risks such as injury of iliac vessels, injury of the peritoneal contents, ureters and of the autonomic nervous system, made it necessary to search for alternative procedures in order to obtain access to the lumbar spine with a minimum complication rate ; this is where the minimally invasive procedures of column to arise. In May 1997, Mayer describes a minimally invasive anterior approach to the lumbar spine, through a retroperitoneal approach for L2-L3 to L4-L5 spaces and a transperitoneal approach to L5-S1, which procedures are performed after fixation posterior and instrumentation. He developed this technique in 25 patients, obtaining a high fusion rate in all patients, with minimal blood loss and no evidence of postoperative complications. Kaiser et al., Reproduced this technique in 51 patients, showing a rate of 3.9% of intraoperative complications and 17.6% of immediate complications postoperatively. Later, Saraph and colleagues compared the technique described by Mayer with the traditional anterior approach; Is monitored for approximately 5.5 years and concludes that the fusion rate between the two groups is similar, however intraoperative blood loss, surgical time, and postoperative low back pain are lower in the minimally invasive technique. Hence this technique is referred to as OLIF (Oblique Lumbar Interbody Fusion) In contrast to other minimally invasive techniques such as Extreme Lateral Interbody Fusion (XLIF), it has been shown superiority considering that it produces less invasion of the psoas muscle and the lumbar plexus, allows direct visualization of the nerves, ureter and sympathetic trunk ; Thus achieving a better rate of nerve injury and improvement of pain POP
