Etiologies of cervical kyphosis are diverse and may include neuromuscular, degenerative, post-traumatic, neoplastic, and iatrogenic conditions as well as systemic conditions such as ankylosing spondylitis and rheumatoid arthritis.

Surgical correction should be considered if the patient does not respond to a nonoperative treatment or demonstrates evidence of progressive myelopathy, radiculopathy, or functional disability, such as inability to achieve horizontal gaze, tension-/kyphosis-induced myelopathy, neck pain due to head imbalance, or swallowing dysfunction related to head position. Surgical correction of cervical kyphosis is challenging and requires a clear understanding of the disease and the patient. The surgeon must be very comfortable with remobilizing the spinal column anteriorly and posteriorly, with vertebral artery anatomy and with methods of anterior and posterior correction. This chapter details the preoperative considerations and surgical procedures of two of the most common cervical osteotomies for cervical kyphosis: (1) Smith-Petersen osteotomy and the C7 subtraction osteotomy (PSO).
