• An anterior approach to the lumbar spine is increasingly used in performing fusion. Depending on the level to be treated, several approaches have been developed to deal with the anatomic obstacles encountered: pure anterior, oblique anterior or lateral, and trans- or pre-psoas. Conventional techniques incur risk of muscle lesion and severe bleeding, and have been replaced by minimally invasive approaches, often with video assistance after rapid closure of laparoscopic approaches with gas insufflation. There has, in parallel, been great progress in anterior spinal instrumentation systems. Non-existent when these techniques were first developed, they have become increasingly sophisticated, and now employ a variety of stand-alone or not cages and anterior screwed plate that can be associated together or to posterior fixation. Each approach and type of fixation has its specific technical requirements that need to be fully mastered so as to minimize risk, especially regarding vessels, and to enable the patient to enjoy the benefit of their very low morbidity. We shall therefore detail here each step of the pure anterior approach, which is most often used for L5S1, the oblique and lateral approaches, mainly used for L2L5, and also the preparation of the lumbar spine for anterior interbody fusion, with the respective instrumentations. We shall then consider the pros, cons and risks, and also spinal or general contraindications that may sometimes preclude this option. From this, we shall derive the specific optimal and wrong indications for anterior lumbar surgery, to help decision-making when fusion is indicated.
