In the present study with beagle dogs, we demonstrated that this new screw had stronger anchor effects for both normal and osteoporotic vertebrae than non-expandable spinal pedicle screws. And then, our research showed that the more expandable screw had the stronger anchor for normal vertebrae, not for osteoporotic vertebrae.","subitem_description_type":"Abstract"}]},"item_8_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2014年度～2016年度科学研究費補助金(基盤研究(C))研究成果報告書","subitem_description_type":"Other"}]},"item_8_description_64":{"attribute_name":"科研費番号","attribute_value_mlt":[{"subitem_description":"26462239","subitem_description_type":"Other"}]},"item_8_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学"}]},"item_8_text_31":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_value":"ミエダイガク"}]},"item_8_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Kaken / 科研費報告書"}]},"item_8_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"笠井, 裕一","creatorNameLang":"ja"},{"creatorName":"KASAI, Yuichi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"榊原, 紀彦","creatorNameLang":"ja"},{"creatorName":"SAKAKIBARA, Toshihiko","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-08"}],"displaytype":"detail","filename":"2018RP0021.pdf","filesize":[{"value":"166.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"2018RP0021","url":"https://mie-u.repo.nii.ac.jp/record/12415/files/2018RP0021.pdf"},"version_id":"9ac6e89c-65b8-4e43-8aa3-0e1b1fb609d6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"生体力学","subitem_subject_scheme":"Other"},{"subitem_subject":"脊椎外科","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"Expandable pedicle screw system の基礎的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Expandable pedicle screw system の基礎的研究","subitem_title_language":"ja"},{"subitem_title":"biomechanical studies of expandable pedicle screw system","subitem_title_language":"en"}]},"item_type_id":"8","owner":"15","path":["1692670416720"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2019-05-08"},"publish_date":"2019-05-08","publish_status":"0","recid":"12415","relation_version_is_last":true,"title":["Expandable pedicle screw system の基礎的研究"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-11-08T04:03:37.668495+00:00"}
