head index)、臼蓋荷重部傾斜角などの計測と、股関節症に特徴的な異常所見を理解しておくことが重要である。臼蓋形成不全に起因する亜脱臼性股関節症は、股関節の解剖学的構造に欠陥があるので、保存療法で疾患が治癒することはない。CE角が20℃以下の患者では慎重な経過観察が必要であり、何らかの股関節症状を有する若年患者に対しては、臼蓋形成術が適応となる。また、特発性大腿骨頭壊死症の早期診断においてはMRIが極めて有用で、多くの例において単純X線像より早く異常所見が出現し、壊死範囲と局在部位を正確に判定することが可能である。MRIによる大腿骨頭壊死症の特徴的な所見は、T1強調画像における帯状の低信号域(band pattern)であり、このバンドより中枢側が壊死域である。早期に壊死範囲と部位を正確に判定することは、治療方針を決定するうえで重要である。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_5_description_36":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"雑誌掲載版","subitem_description_type":"Other"}]},"item_5_description_37":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_5_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_5_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0914-8124","subitem_source_identifier_type":"PISSN"}]},"item_5_text_44":{"attribute_name":"ID(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"2010040195"}]},"item_5_text_54":{"attribute_name":"閲覧数(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"1089"}]},"item_5_text_55":{"attribute_name":"ダウンロード数(XooNIps)","attribute_value_mlt":[{"subitem_text_value":"1512"}]},"item_5_text_7":{"attribute_name":"著者
