The Correlation between Pain and Necrotic Area and Joint Effusion of Osteonecrosis of the Femoral Head in Early and Medium-Term
Abstract：Objective To study the correlation between necrosis area,joint effusion and pain in early and medium-term osteonecrosis of the femoral head. Methods 76 cases(116 hips)with osteonecrosis of the femoral head were studied. There were 47 male and 25 female with a mean age of 39 years old(21 ~ 62 y ). And there were 55 case of left hip,cases of the right hip. There 5 hips in stage Ⅰ,44 hips in stage Ⅱ,67 hips in stage Ⅲ according to ARCO. All cases underwent standard antero-posterior and frog-leg X -ray;axial CT scans and coronal,sagittal reconstruction. All cases underwent MRI examination to esti-mate the necrotic area and the effusion grade. The ARCO stage were judged according to the findings of MR,CT and X -rayg. The joint effusion estimated according to the methods of Liu. The degree of pain was judged using the methods of VRS(Verbal rating scale). The Kruskal-Wallis rank-sum test was used. Results The pain gradually worsened with the progress of the fem-oral head necrosis,The pain symptoms were worse with the necrotic area greater in stage Ⅱ and stage Ⅲ. The joint effusion and pain were positively correlated. Conclusion The correlation exist between the pain symptoms of osteonecrosis of the femo-ral head and the necrotic area and joint effusion. The pain symptoms were worse with the necrotic area and fluid volume increa-ses.
