The History of Anterior and Lateral Approaches to the Lumbar Spine

Anterior and lateral approaches to the lumbar spine are commonly used today for a variety of indications. These approaches can ultimately be traced back to early attempts to treat Pott's disease. Evidence of Mycobacterium tuberculosis infection of the spine dates as far back as 2400 BCE, with ancient Egyptian mummies exhibiting lesions consistent with Pott's disease. For many centuries, Pott's disease was treated conservatively, and surgery came to be used when conservative therapy was ineffective, as medical therapy had yet to become available. In 1779, Percivall Pott recommended that peripheral paraspinal tuberculous abscesses be drained after noticing that patients' lower limb function improved after the formation of spontaneous draining sinuses. Building on Pott's ideas, Ménard described the first lateral approach to the spine via a costotransversectomy approximately 1 century after Pott's theory. Most importantly, the surge in understanding anatomy with respect to developing safe corridors to the deeper structures of the human body brought together advances in technology, instrumentation, and visualization. Surgeons were thus emboldened to explore more complex anterior approaches to the spine. In 1906, Müller reported the first successful anterior approach to the spine in a patient with Pott's disease. Over the next several decades, the efforts of surgeons such as Ito, Capener, Burns, and Mercer would lead to the development of the anterior lumbar interbody fusion. The costotransversectomy later evolved into the lateral rhachotomy and lateral extracavitary approach, which along with advances in the anterior lumbar interbody fusion paved the way for the oblique lumbar interbody fusion and lateral lumbar interbody fusion.
