Association between roentgenographic findings of the cervical spine and neck symptoms in a Japanese community population

Abstract

BackgroundRadiographic findings may provide clues to the underlying cause of neck symptoms. However, these associations remain controversial. This study investigates the association between roentgenographic findings of the cervical spine and neck symptoms in a Japanese community population.MethodsA total of 762 volunteers participated in this study. Sagittal radiographs of the cervical spine were taken and a questionnaire about the presence of and visual analog scale (VAS) for neck pain or stiff shoulder was completed. The sagittal alignment of the cervical spine (C2–C7) and the degenerative index were measured from lateral aspect radiographs. Three groups based on the sagittal alignment of C2–C7 were defined: straight-spine, lordotic-spine, and kyphotic-spine. The roentgenographic findings were examined in relation to symptoms.ResultsThe prevalence rate of stiff shoulder on the day of examination was significantly higher in females than males. Although the VAS for neck pain and stiff shoulder on the examination day and for stiff shoulder in the preceding 12 months were not significantly different between females and males, that for neck pain in the preceding 12 months was significantly higher in females than males. Although there was no association between the sagittal alignment of C2–C7 and neck symptoms in males or females, a significant correlation between the degenerative index and VAS for neck pain on the examination day and in the preceding 12 months was seen in females after adjusting for age. The prevalence of and VAS for neck pain and stiff shoulder were not significantly different among the three C2–C7 sagittal alignment groups.ConclusionAlthough the sagittal alignment of the cervical spine was not associated with neck symptoms, degenerative changes were associated with the severity of neck pain in females.

Clinical characteristics in patients with ossification of the posterior longitudinal ligament: A prospective multi-institutional cross-sectional study

“…OPLL was first described in the 1960s 14 and is now understood to result from heterotopic bone formation in the posterior longitudinal ligament of the spine and to be a common cause of myelopathy, especially in Asia. Although several researchers have investigated the symptoms of OPLL and the efficacy of surgery, there are few reports on pain and impairment of ADL in patients with this disorder 15,16 . Sasaki et al reviewed a sample (n = 1291) of the general population in Japan and divided it into subjects with and without OPLL 15 .…”

Association between cervical lordotic curvature and cervical muscle cross‐sectional area in patients with loss of cervical lordosis

“…There have been many studies of the effect of the loss of cervical lordosis on clinical symptoms (Harrison et al 2002b(Harrison et al , 2004McAviney et al 2005;Shimizu et al 2005). Studies of the relationship between loss of cervical lordosis and neck pain have been published but the results are controversial (McAviney et al 2005;Kumagai et al 2014;Shilton et al 2015). Grob et al compared the cervical lordosis angle between groups with and without neck pain and found no significant difference (Grob et al 2007).…”

Low prevalence of knee chondrocalcinosis and its catabolic association with serum matrix metalloproteinase 3: A rural Japanese population study

“…Many types of medical specialists are involved in this project, including orthopedic specialists, physicians, general surgeons, gynecologists, urologists, psychiatrists, dermatologists and dentists. To evaluate locomotor system function, orthopedic specialists of our department have collected biochemical and biomechanical data associated with knee OA, including that of the spine and hip joint …”
