BACKGROUND CONTEXT: @entity130 and @entity32 have been proposed as causes of acute benign spinal @entity158 , but this etiology has not been investigated. PURPOSE: To investigate the presence of periarticular tissue @entity32 and zygapophysial joint @entity603 in the cervical region using magnetic resonance imaging (MRI) in subjects with acute unilateral cervical @entity158 and limited motion (acute "crick in the neck" <48 hours from onset), as well as the feasibility of recruiting these subjects. STUDY DESIGN/SETTING: Three-month case series in a university setting and private radiology clinic. @entity1 SAMPLE: Five subjects (three @entity1 and two @entity1 ; mean age, 31.6 years; @entity5494 [ @entity5494 ], 12.4). METHODS: Each subject was examined by a researcher experienced in manual medicine to assess active range of neck movement and the side and symptomatic segmental level of @entity158 . Subjects then underwent a blinded MRI investigation, which included sagittal images through the entire neck and cervical spine and axial images from C2 to T1. Evidence of capsule or periarticular @entity4 and joint space T2 increase was recorded and scored. Additionally, signs of @entity4 , alignment, @entity66 , facet @entity5144 , and @entity612 were recorded. RESULTS: Subjects presented with mean current @entity158 of 4.8 ( @entity5494 , 1.6; visual analog scale, 0-10), worst @entity158 since onset of 7.0 ( @entity5494 , 0.7), and duration of symptoms of 12.4 hours ( @entity5494 , 14.1). The plane of active motion most commonly limited was rotation to the @entity158 side, followed by side bending to the @entity158 side and extension. No MRI findings demonstrated clear evidence of @entity1143 or @entity32 around the joints of the cervical spine. In some individuals, signs of @entity4 , altered alignment, disc and facet @entity4040 , and @entity612 were noted, but these did not appear to be related to the side of @entity158 or symptomatic level. CONCLUSIONS: No evidence of @entity32 was detected, and more sensitive imaging methods may be required to detect inflammatory changes in or around the cervical joints of subjects with acute @entity4048 . Recruitment of subjects with acute "crick in the neck" @entity158 (<48 hours duration) is difficult but feasible over a long data collection period.
