To date, there have been few reports discussing the quantitative analysis of how much the contact surface area of the cup has to decrease before the fixation strength of a press-fit cup is affected.\nIn the present study, the contact surface area of the sliding portion of the cup was varied, and this contact surface area was varied in order to conduct comparison testing of mechanical properties, to see whether there was any impact caused by the presence or absence of fins. Bone models were prepared presuming the hardness of actual human acetabula, and their mechanical properties were tested. After performing 1-mm underreaming so that the entire rim of the cup was in contact, taking into consideration possible effects from the presence or absence of bone defects caused by acetabular aplasia, bone defect models were cut so that the cup protruded beyond the rim of the acetabular cartridge and angles of 10 °, 20 °, 30 ° and 40° were created, and, presuming re-reaming with respect to the acetabula during surgery, models with 1-, 2-, 3-, 6-, and 9-mm eccentricity were tested. With the bone defect models, the contact surface area decreased (10°, 94.4%; 20°, 88.9%; 30°, 83.3% and 40°, 78.6%), while in the eccentricity models, the contact surface area increased again at eccentricities of 6 mm or more (1mm, 60.4%;2mm, 56.7%; 3 mm, 56.2%; 6 mm, 57.8%; and 9 mm, 60.4%). In the models with fins, the maximum torque values were as follows: 0°, 60.1 N/m; 10°, 58.8 N/m; 20°, 50.2 N/m; 30°, 25.3 N/m and 40°, 17.4N/m. In the models without fins, the values were as follows: 0°, 46.2 N/m; 10°, 40.4 N/m; 20°, 23.5 N/m; 30°, 13.9 N/m and 40°, 7.4N/m. There was an extreme decrease in the rotational torque value at 30 ° or more, compared to that at 20 °. In models in which eccentricity was applied, at 2 mm or more, when it is difficult for the fins to engage, there was an extreme decrease in the rotational torque. In conclusion, the decrease in the contact surface area between the cup and bone and the reduced engagement of the fins strongly affected the decrease in rotational force."}]},"item_10001_textarea_6":{"attribute_name":"抄録(日)","attribute_value_mlt":[{"subitem_textarea_language":"ja","subitem_textarea_value":"セメントレスTHA において安定したスクリューレスCup の初期固定を得るには，高い回旋開始時トルク値で初期固定力を確保し，高範囲かつ適切な接触領域の分布を示すことが重要と考える．これまでCup の接触面積がどの程度減少してしまうと，固定力に影響するか力学試験解析した報告は少ない．Cup 摺動部の接触領域を変化させ，実際のヒト寛骨臼の硬さを想定したボーンモデルを作製しフィンの有無が与える影響について力学試験を行った．Cup の辺縁全周が接触するように1mm のアンダーリーミングを行った後に，臼蓋形成不全による骨欠損の有無の影響を考慮し，Cup が臼蓋縁よりはみ出すように骨モデルを10°，20°，30°，40°の角度をつけてカットした骨欠損モデルと，術中の臼蓋に対し再リーミングを想定し1，2，3，6，9mm 偏心したモデルにおいて検討した．骨欠損モデルでは接触面積が10°：94.4%，20°：88.9％，30°：83.3%，40°：78.6％と小さくなり，偏心モデルにおいては1mm：60.4%，2mm：56.7%，3mm：56.2%，6mm：57.8%，9mm：60.4% と6mm 以上の偏心で接触面積は再増加した．最大トルク値では，フィン有りは0°：60.1N/m，10°：58.8N/m，20°：50.2N/m，30°：25.3N/m, 40°：17.4N/m．フィン無しは0°：46.2N/m，10°：40.4N/m，20°：23.5N/m，30°：13.9N/m，40°：7.4N/m であった．フィンの有無に関わらず30°で回旋トルクが著明に低下していた．力学試験においては30°以上において回旋トルク値が極端に低下した．偏心モデルでは2mm 以上で回旋トルクが極端に低下した．結論として，骨との接触面積が減少し，さらにはフィンの掛かりが減少したことが，回旋力低下の要因に大きく影響した．"}]},"item_10001_version_type_20":{"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":"河本, 豊広","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"難波, 良文","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"梅原, 憲史","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三宅, 由晃","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古市, 州郎","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"三谷, 茂","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAMOTO, Toyohiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NANBA, Yoshifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"UMEHARA, Norifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MIYAKE, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FURUICHI, Shuro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MITANI, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-03-09"}],"displaytype":"detail","filename":"KMJ-J42(2)117.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PDF","objectType":"fulltext","url":"https://kwmed.repo.nii.ac.jp/record/1842/files/KMJ-J42(2)117.pdf"},"version_id":"5a6541b9-18d6-48f6-b04a-a351083e148a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"スクリューレスカップ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"人工股関節全置換術","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"大骨頭","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"回旋抵抗","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Screwless","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Total hip arthroplasty","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Large head","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Friction torque","subitem_subject_language":"en","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Screwless Cup 摺動部の接触面圧力の力学的解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Screwless Cup 摺動部の接触面圧力の力学的解析","subitem_title_language":"ja"},{"subitem_title":"Mechanical analysis of contact pressure of\\nScrewless uncemented cup bearings","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"31","path":["597"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-03-09"},"publish_date":"2017-03-09","publish_status":"0","recid":"1842","relation_version_is_last":true,"title":["Screwless Cup 摺動部の接触面圧力の力学的解析"],"weko_creator_id":"31","weko_shared_id":-1},"updated":"2024-04-16T02:03:03.712903+00:00"}
