Study Design Case-control study. Background Cervical spine meniscoids are thought to contribute to neck pain and hypomobility in individuals with chronic whiplash associated disorder (WAD), however their morphology has not been studied in a clinical population. Objectives To investigate cervical spine meniscoid morphology in individuals with chronic WAD. Methods Twenty volunteers with chronic WAD (mean [SD] age 39.3 [11.0] years, 10 female) and 20 age and sex-matched controls (39.1 [10.6] years) underwent cervical spine magnetic resonance imaging. Lateral atlantoaxial and zygapophyseal joints (C2/3 to C6/7) were inspected for meniscoids. Length of meniscoid protrusion was measured and composition (adipose/fibrous/fibroadipose) assessed. Data were analyzed using Wilcoxon signed-rank tests and linear and logistic regression (P < .05). Results Meniscoids were identified in the chronic WAD (n = 317) and control (n = 296) groups. At the lateral atlantoaxial joints, median meniscoid length was greater in the control group (ventral 6.07 mm; dorsal 7.24 mm) than WAD group (ventral 5.01 mm, P = .06; dorsal 6.48 mm, P < .01). At the dorsal aspect of zygapophyseal joints, meniscoids were more frequently fibrous in the chronic WAD group (odds ratio 2.38, P < .01; likelihood ratio test [LRT] Chi-square [2] = 9.02, LRT P = .01). Conclusion In individuals with chronic WAD, lateral atlantoaxial meniscoids were shorter and dorsal cervical zygapophyseal meniscoids were more fibrous, suggesting alterations in meniscoid composition. This may have pathoanatomical implications in chronic WAD. J Orthop Sports Phys Ther, Epub 3 Sep 2016. doi:10.2519/jospt.2016.6702.
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 13 January 2018.
All research outputs
#9,389,233
of 34,365,356 outputs
Outputs from Journal of Orthopaedic & Sports Physical Therapy
#1,515
of 2,749 outputs
Outputs of similar age
#96,876
of 337,057 outputs
Outputs of similar age from Journal of Orthopaedic & Sports Physical Therapy
#30
of 43 outputs
Altmetric has tracked 34,365,356 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 2,749 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 26.7. This one is in the 44th percentile – i.e., 44% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 337,057 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 71% of its contemporaries.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
