Osteochondroma is described as a capped benign bony neoplasm that forms on the outer surface of bone. These tumors affect nearly 6 million people per year. While osteochondromas most often involve the appendicular skeleton, a significant portion involve the spine with many cases located in the cervical spine. When osteochondromas involve the spine, they can present with a variety of symptoms including pain, radiculopathy and myelopathy which may necessitate surgical treatment. Spinal osteochondromas can be classified into two types: multiple osteochondromas in the context of patients with multiple hereditary exostosis (MHE), and solitary osteochondromas or solitary exostosis (SE). Previous reviews have only captured portions of the available literature on cervical osteochondromas and generally focus on either SE or those associated with MHE. The purpose of our review was to provide an extensive review of all previously reported cervical osteochondromas and to compare osteochondroma characteristics, clinical presentation and outcomes in the context of MHE and SE.
