The Study: Relationship between degree of focal kyphosis correction and neurological outcomes for patients undergoing cervical deformity correction surgery. The Facts: a. Cervical kyphosis “can lead to mechanical pain, neurological dysfunction, and functional disabilities.” b. Therefore the more you move the kyphosis toward lordosis the more improvement there might be in outcomes. c. The authors […]
The Study: Cervical spine alignment, sagittal deformity, and clinical implications: a review The Facts: a. The authors reviewed normal cervical alignment, how to measure cervical alignment in the sagittal plane and the effect of cervical misalignment (cervical kyphosis in this case) on health-related quality of life (HRQOL). b. Recent studies suggest a correlation between cervical […]
J Manipulative Physiol Ther. 2005 Mar-Apr;28(3):187-93. McAviney J1, Schulz D, Bock R, Harrison DE, Holland B. Abstract OBJECTIVE: To investigate the presence of a “functionally normal” cervical lordosis and identify if this and the amount of forward head posture are related to neck complaints. METHODS: Using the posterior tangent method, an angle of cervical lordosis was measured from C2 through C7 vertebrae on 277 lateral cervical x-rays. Anterior weight bearing […]

Comparison of axial and flexural stresses in lordosis and three buckled configurations of the cervical spine. AuthorsHarrison DE, et al. Show all Journal Clin Biomech (Bristol, Avon). 2001 May;16(4):276-84. Affiliation Abstract OBJECTIVE: To calculate and compare combined axial and flexural stresses in lordosis versus buckled configurations of the sagittal cervical curve.
