Snippet: Degree of clinical pain was evaluated based on visual analog scale (VAS) approach. Harris score, as a standard evaluation to various hip disabilities and methods of treatment (full mark =100), was used for assigning good, satisfactory, acceptable and unfavorable conditions as higher than 89, 80-89, 70-79 and ,70, respectively. Imaging examination was performed on all patients. Volume and volume ratio of femoral necrosis were calculated based on m.....
Document: Degree of clinical pain was evaluated based on visual analog scale (VAS) approach. Harris score, as a standard evaluation to various hip disabilities and methods of treatment (full mark =100), was used for assigning good, satisfactory, acceptable and unfavorable conditions as higher than 89, 80-89, 70-79 and ,70, respectively. Imaging examination was performed on all patients. Volume and volume ratio of femoral necrosis were calculated based on magnetic resonance imaging (MRI) images. 11 All patients were examined with imaging techniques. The degree of ONFH shown on imaging was graded according to Association Research Circulation Osseous (ARCO) staging criteria. The volume and volume ratio of femoral necrosis were analyzed based on MRI images by using a published calculating method. 11 By comparing with actual measurement from surgical specimens, the MRI image-based calculation was demonstrated to be close to actual values.
