Abstract

Hip ultrasonography with the Graf method is used worldwide. Four different projections can be used for the evaluation of sonographic images. The best projection with the lowest rate of wrong interpretation is the “standing-up right”-projection and the worst is the ‘’horizontal-cranial left’’ projection. The aim of this study was to show the concordance of two researchers using these two different projections. Hip sonographic evaluation according to the Graf method was applied to 166 infants (332 hips) comprising 84 males (50.6%) and 82 females (49.4%). The hip sonographic images were obtained in both the standing-up right and horizontal-cranial left projections. Two researchers independently measured the alpha and beta angles manually with a goniometer and classified the hip type. The alpha, beta angle measurement values, comparisons of the angles in both projections and for both researchers are presented in detail in Tables 1 and 2. The inter-observer agreement of the Graf types of hips was as follows; Graf types between researcher 1 and 2, Right hip- (standing-up right) Kappa value 0.84, Left hip- (standing-up right) Kappa value 0.77, Right hip- (horizontal-cranial left) Kappa value 0.67, Left hip- (horizontal-cranial left) Kappa value 0.64. The intraclass correlation coefficient (ICC) values of the agreement between the two researchers for all the measured hip angles were as follows; right angle ICC: 0.96, right angle ICC: 0.91, left angle ICC: 0.93, and left angle ICC: 0.59. Although the standing-up right projection is known to be the best projection with the lowest rate of wrong interpretation according to the Graf guidelines, the results of this study showed the evaluation of similar Graf hip types on the two projections. Therefore, the horizontal cranial left projection, which is considered to be the worst of the four projections, can be used safely for hip evaluation if the Graf checklist is followed appropriately.

Abstract

Graf yöntemi ile kalça ultrasonografisi dünya çapında kullanılmaktadır. Sonografik görüntülerin değerlendirilmesinde dört farklı projeksiyon kullanılabilmektedir. En az yanlış yorumlama oranı ile ‘’dik-sağ’’ projeksiyon en iyi ve ‘’yatay-baş sol’’ projeksiyon ise en kötü olanıdır. Bu çalışmanın amacı, iki araştırmacının bu iki değişik projeksiyondaki uyumunu göstermektir. Graf metoduna göre kalça sonografik değerlendirmesi 84 erkek (%50.6) ve 82 kız (%49.4) dan oluşan 166 (332 kalça) bebeğe uygulanmıştır. Sonografik görüntüler hem dik-sağ hemde yatay-baş sol projeksiyonda elde edilmiştir. İki araştırmacı birbirinden bağımsız olarak gonyometre ile elle alfa ve beta açılarını ölçmüş ve kalça tiplendirmesini yapmışlardır. Tablo 1 ve 2 de ayrıntılı olarak, alfa beta açı ölçüm değerleri, ve açıların her iki projeksiyonda ve her iki araştırmacıya göre karşılaştırması sunulmuştur. Kalçaların Graf tiplerinin gözlemciler arası uyumu şöyleydi; araştırmacı 1 ve 2 arasındaki Graf tipleri, Sağ kalça (dik-sağ) Kappa değeri 0.84, sol kalça (dik-sağ) Kappa değeri 0.77, sağ kalça (yatay-baş sol) Kappa değeri 0.67, sol kalça (yatay-baş sol) Kappa değeri 0.64 dür. Tüm ölçülmüş kalça açıları için iki araştırmacı arasındaki Intraclass Korelasyon Katsayısı (IKK) değerlerinin uyumu şöyleydi; sağ alfa açısı IKK: 0.96, sağ beta açısı IKK: 0.91, sol alfa açısı IKK: 0.93, ve sol beta açısı IKK: 0.59. Dik-sağ projeksiyon, Graf’ ın yönergelerine göre en az yanlış yorumlama oranlarına sahip olsa da, bu çalışmanın sonuçları iki projeksiyonda da Graf kalça tiplerinin değerlendirmesinin benzer olduğunu gösterdi. Bu nedenle, dört projeksiyon içinden en kötüsü olan yatay-baş sol projeksiyon, eğer Graf’ın kontrol listesine doğru bir şekilde uyulursa kalça değerlendirmesinde güvenli bir şekilde kullanılabilir.
