Background: Decompression and fusion with autograft is the gold standard technique in the treatment of narrowing of the cervical canal. Using polyetheretherketone (PEEK) cages or nonabsorbable polymer boxes with elasticity similar to bone, radiolucent, and the same degree of fusion reduces morbidity. methods: We carried out a prospective, longitudinal, deliberate intervention case series with e...

PURPOSE Decompression and maintaining or restoring a cervical lordosis are major goals in the surgical treatment of cervical spondylotic myelopathy (CSM). Numerous studies support the assumption that cervical lordosis is a key factor for neurological recovery and pain reduction. However, even kyphotic patients can be asymptomatic. The balance of the spine is subject of an increasing number of p...

BACKGROUND Cervical lordosis has been shown to be an important outcome of care; however, few conservative methods of rehabilitating sagittal cervical alignment have been reported. OBJECTIVE To study whether a seated, retracted, extended, and compressed position would cause tension in the anterior cervical ligament, anterior disk, and muscle structures, and thereby restore cervical lordosis or...

OBJECTIVE The maintenance of post-operative lordosis has been shown to be a key factor in decreasing adjacent level disc stress. Previous studies of the PEEK (polyether ketone) cage have used intervertebral bony fusion as the primary measure of surgical success; however, little is known about its effects on spinal curvature. Our objective was to compare the PEEK cage to the cervical plate with ...

PURPOSE The cervical dynamic rotational plating system may induce bone graft subsidence, so it may cause loss of cervical lordosis. However there were few studies for alignments of cervical spines influencing the clinical results after using dynamic rotational plates. The purpose is to evaluate the effect of graft subsidence on cervical alignments due to the dynamic rotational cervical plates a...

STUDY DESIGN This is a prospective study design. OBJECTIVE To test the interobserver and intraobserver reliabilities of 5 specific measures of global cervical sagittal alignment in patients with ankylosing spondylitis (AS), and to suggest a better means of measuring cervical sagittal alignment. SUMMARY OF BACKGROUND DATA The intraobserver and interobserver reliabilities of several different...

It is widely believed that using a pillow that allows appropriate neck support to maintain cervical lordosis during sleep can lead to better quality sleep.Conversely, use of the wrong type of pillow can compromise pain-sensitive structures and produce waking symptoms, such as cervical pain and stiffness, headaches, and arm pain; and this in turn results in reduced sleep quality. Therefore, the ...

STUDY DESIGN Retrospective study. OBJECTIVE To assess the relationship between sagittal alignment of the cervical spine and patient-reported health-related quality-of-life scores following multilevel posterior cervical fusion, and to explore whether an analogous relationship exists in the cervical spine using T1 slope minus C2-C7 lordosis (T1S-CL). SUMMARY OF BACKGROUND DATA A recent study ...

Background Previous studies on the correlation between cervical sagittal balance with improvement in quality of life showed significant results only for parameters of the anterior translation of the cervical spine (such as C2-C7 SVA). Objective We test whether a new parameter, cervicothoracic lordosis, can predict clinical success in this type of surgery. Methods The focused group involved ...
