RESUMEN
STUDY DESIGN: A literature review regarding the correlation between a kyphotic neck and its clinical outcomes. OBJECTIVES: This review examines normal cervical alignment, methods for assessing alignment, a specific correlation between kyphotic neck and clinical outcomes, and indications and methods of surgical treatment. SUMMARY OF LITERATURE REVIEW: Cervical kyphotic deformity is problematic in terms of HRQOL due to nerve damage or loss of horizontal gaze. MATERIALS AND METHODS: Review of the literature. RESULTS: Cervical kyphosis can be caused by postlaminectomy, degenerative disc disease, and trauma, and the symptoms exhibit diverse clinical progression including compensatory mechanisms, adjacent segment disease, changes in quality of life, and cervical myelopathy. Given the serious complications of cervical surgery, we need a deep understanding of spine anatomy, preoperative planning, and correction methods. CONCLUSIONS: It is vital to investigate cervical sagittal alignment and to perform intensive treatment and corrective surgery to achieve better clinical outcomes.
