| الملخص: | <h3>Purpose</h3><p dir="ltr">To develop a specified radiographic scoring system for the pubic symphysis and adjacent bones, and to examine the intra- and inter-rater reproducibility of this system.</p><h3>Method</h3><p dir="ltr">Development of the scoring protocol was performed in three stages using AP pelvis radiographs of 102 male adult athletes. The final protocol included 5 overall scoring items, which included further specification of locations: 1) bone lucency (erosion-like configuration and cysts), 2) proliferation, 3) fragmentation, 4) sclerosis, and 5) joint space width. Intra- and inter-rater reproducibility were determined using Cohen’s kappa statistic (κ) and intraclass correlation coefficient (ICC). The standard error of measurement (SEM) and minimal detectable difference (MDD) were also determined.</p><h3>Results</h3><p dir="ltr">We present a radiographic scoring protocol with clear definitions and examples to improve clinical usability. Intra-rater reproducibility was: bone lucency (erosion-like configuration or cysts): κ = 0.67 (95 %CI 0.56−0.78), proliferation: κ = 0.54 (95 %CI 0.38−0.70), fragmentation: κ = 0.80 (95 %CI 0.67−0.93), sclerosis: κ = 0.60 (95 %CI 0.49−0.71), and joint space width: ICC(2.1) 0.85 (95 %CI 0.78−0.89), SEM 0.4 mm, MDD 1.2 mm. Inter-rater reproducibility was: bone lucency: κ = 0.61 (95 %CI 0.50−0.72), proliferation: κ = 0.34 (95 %CI 0.20−0.48), fragmentation: κ = 0.67 (95 %CI 0.50−0.84), sclerosis: κ = 0.30 (95 %CI 0.17−0.43), and joint space width: ICC(2.1) 0.72 (95 %CI 0.59−0.81), SEM 0.5 mm., MDD 1.5 mm.</p><h3>Conclusions</h3><p dir="ltr">The Aspetar pubic symphysis radiographic scoring protocol contains five overall scoring items, with additional specifications. These five items showed moderate to almost perfect intra-rater reproducibility, and fair to substantial inter-rater reproducibility. This protocol provides the basis for use in clinical practice, and will allow future investigations of the clinical significance of radiographic changes at the pubic symphysis in athletes.</p><h2>Other Information</h2><p dir="ltr">Published in: European Journal of Radiology<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.ejrad.2020.109452" target="_blank">https://dx.doi.org/10.1016/j.ejrad.2020.109452</a></p> |
