A straight cervical spine is an underappreciated and often overlooked finding in fibromyalgia. The aim of this medical records review study was to evaluate the cervical curvature on radiographs of patients with fibromyalgia.A consecutive series of 270 cervical spine radiographs of patients with neck pain from 2015 to 2018 were retrospectively analyzed for cervical curvature using the Cobb angle measurement. One hundred fifty-five patients met full American College of Rheumatology criteria for fibromyalgia, whereas 115 subjects with other rheumatic diseases who were similar in age and education served as control subjects.Mean cervical curvature in fibromyalgia was 6.4 ± 5.2 degrees and 13.8 ± 7.4 degrees in control subjects. The more than 7-degree difference was significant (p0.001). Curvature in the magnitude of 21 degrees is at the low end of normal. At ≤10 degrees, where the cervical spine is essentially straight, there were 129 fibromyalgia patients (83.2%) and 37 control subjects (32.2%). The 51% difference was significant (p0.001).Most patients with fibromyalgia share an abnormality in common that is verifiable by a simple radiograph. In 83.2% of the patients, the cervical spine was essentially straight (Cobb angle ≤10 degrees). In fibromyalgia patients, the loss of cervical curvature was approximately 6.5 times greater than in control subjects (50.3% vs. 7.8%). A straight neck without other radiographic abnormalities may be a major anatomical abnormality in fibromyalgia that has gone unnoticed. It may assist in the diagnosis, as well as suggest increased muscle tension/pressure as a possible etiology. |
