Study Design:
Literature review.
Objective:
To document the historical contributions from the Harvard Medical School system to the field of adult spine surgery.
Summary Of Background Data:
Despite the fact that significant contributions to the discipline of spinal surgery have derived from the Harvard system, no prior study documents the history of the Harvard spine services in a cohesive narrative.
Methods:
This historical perspective reviews the history of adult spine surgery within the Harvard system and outlines the significant contributions made by orthopedic and neurosurgical practitioners to the field. Literature reviews were performed from historical works, as well as scientific publications to fashion a cohesive review covering the history of spine surgery at Harvard from the early 19th century to the present.
Results:
The development of the spine surgical services at the three main Harvard hospitals, and significant spine surgical personalities within the system, are discussed, including W. Jason Mixter, MD, Joseph S. Barr Sr., MD, and Marius N. Smith-Petersen, MD. Substantial developments that have arisen from the Harvard teaching hospitals include the recognition of disc herniation as the cause of radicular symptoms in the lower extremities, the description of lumbar discectomy as a surgical treatment for radicular pain, osteotomy for the correction of spinal deformity, and the first attempt to create a systematic algorithm capable of informing treatment for cervical spine trauma.
Conclusion:
Despite humble beginnings, the surgeons and scientists at Harvard have influenced nearly every facet of spine surgery over the course of the last two centuries.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
