초록
목적: 본 연구의 목적은 견관절의 석회성 건염에서 발생하는 석회 침착물의 성상에 대한 기존의 단순 방사선학적 분류법들이 가지는 진단적 정밀도(precision)에 대한 평가로써, 관측자간 일치도를 평가하고, 석회 침착물의 치약형 성상 여부를 예측하는데 있어서의 진단적 정확도(accuracy)를 평가하여, 기존의 방사선학적 분류법들이 가지는 진단적 검사로써의 유용성에 대하여 평가하는 것이다. 대상 및 방법: 2010년 3월부터 2013년 9월까지 본원에서 견관절 석회성 건염으로 수술적 치료를 받은 26명 환자(26예 견관절)를 대상으로 후향적 연구를 시행하였다. 관절경하에서 관측한 석회 침착물의 성상은 총 26예 중 14예에서 분필 가루형이었고, 12예에서 치약형이었다. 수술 전 단순 견관절 방사선 검사상 나타나는 석회 침착물의 형태를 G
Purpose: The purpose of current study was to evaluate the validity of the existing radiological classifications as a diagnostic modality for predicting characteristics of calcific deposition in calcific tendinitis of the shoulder joint. For that purpose, we determined the inter-observer reliability for evaluating diagnostic precisions of the classification and also evaluated diagnostic accuracy of predicting the toothpaste type calcific deposition. Materials and Methods: We performed retrospective study with total 26 patients surgically treated with calcific tendinitis of the shoulder joint from March 2010 to October 2013. Two independent observers reviewed preoperative radiographs of shoulder joints, and classified the characteristics of calcific depositions according to the criteria of Gartner, DePalma and Patte. Cohen's kappa were calculated for each classifications to evaluate inter-observer reliability. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio were determined for type of calcific depositions with Gartner type III, DePalma type I, and Patte type II for predicting toothpaste type calcific deposition. Results: The values of Cohen's kappa were the highest in the classification of Patte, 0.62, and the values for the classifications of DePalma and Gartner were 0.56 and 0.36, respectively. The sensitivities for predicting toothpaste type calcific deposition in Gartner Type III, DePalma type I and Patte type II were 83.3%, 91.7%, and 58.3%, respectively. Specificities were 85.7% 50.0% and 64%, positive likelihood ratios were 5.833, 1.833 and 1.633, negative likelihood ratios were 0.194, 0.167 and 0.648, and diagnostic odds ratios were 30.00, 11.00 and 2.52, respectively. Conclusion: There were no radiologic classifications of calcific tendinitis which has both high precision and accuracy. Further studies with other diagnostic modalities such as ultrasonography are needed for predicting characteristics of calcific deposition in calcific tendinitis of the shoulder joint.
