The object of this study was to evaluate the radiographic characteristics of C-2 using multiplanar CT measurements for anchor screw placement in patients with C-1 assimilation (CIA). Insertion of a C-2 pedicle screw in the setting of CIA is relatively difficult and technically demanding, and there has been no report about the optimal sizes of the pedicles and laminae of C-2 for screw placement in CIA. Methods. An institutional database was searched for all patients who had undergone cervical CT scanning and cervical spine surgery between April 2006 and December 2012. Two neurosurgeons reviewed the CT scans from 462 patients who met these criteria, looking for CIA and other anomalies of the craniocervical junction such as high-riding vertebral artery (VA), basilar invagination, and VA anomaly. The routine axial images were reloaded on a workstation, and reconstruction CT images were used to measure parameters: the minimum width of bilateral pedicles and laminae and the length of bilateral laminae of the atlas. Results. Seven patients with CIA were identified, and 14 sex-matched patients without CIA were randomly selected from the same database as a control group. The mean minimum pedicle width was 5.21 mm in patients with CIA and 7.17 mm in those without. The mean minimum laminae width was 5.29 mm in patients with CIA and 6.53 mm in controls. The mean minimum pedicle and laminae widths were statistically significantly smaller in the patients with CIA (p \u003c 0.05). Conclusions. In patients with CIA, the C-2 bony structures are significantly smaller than normal, making C-2 pedicle screw or translaminar screw placement more difficult."}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u9752\u5c71, \u9054\u90ce"}], "nameIdentifiers": [{"nameIdentifier": "108099", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-06-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "18MR0003_yoshi.pdf", "filesize": [{"value": "148.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 148300.0, "url": {"label": "\u5185\u5bb9\u306e\u8981\u65e8", "url": "https://soar-ir.repo.nii.ac.jp/record/20763/files/18MR0003_yoshi.pdf"}, "version_id": "5114f4de-c445-41b4-8fb8-0c73b1d486cb"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-06-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "18MR0003_shinsa.pdf", "filesize": [{"value": "103.7 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 103700.0, "url": {"label": "\u5be9\u67fb\u7d50\u679c\u306e\u8981\u65e8", "url": "https://soar-ir.repo.nii.ac.jp/record/20763/files/18MR0003_shinsa.pdf"}, "version_id": "9c79a7f6-4d27-4f16-8cfb-cd2d1db541f1"}, {"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-06-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 2, "filename": "18MR0003_ronbun.pdf", "filesize": [{"value": "391.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "\u00a9 AANS, 2014", "licensetype": "license_free", "mimetype": "application/pdf", "size": 391900.0, "url": {"label": "\u535a\u58eb\u8ad6\u6587\u306e\u5168\u6587", "url": "https://soar-ir.repo.nii.ac.jp/record/20763/files/18MR0003_ronbun.pdf"}, "version_id": "cc3d5b34-4739-46c7-aec6-d0507e3fdd18"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "thesis", "resourceuri": "http://purl.org/coar/resource_type/c_46ec"}]}, "item_title": "Radiographic measurements of C-2 in patients with atlas assimilation\uff08\u74b0\u690e\u7652\u5408\u75c7\u4f8b\u306b\u304a\u3051\u308b\u8ef8\u690e\u690e\u5f13\u6839\u3068\u690e\u5f13\u306e\u653e\u5c04\u7dda\u5b66\u7684\u691c\u8a0e\uff09", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Radiographic measurements of C-2 in patients with atlas assimilation\uff08\u74b0\u690e\u7652\u5408\u75c7\u4f8b\u306b\u304a\u3051\u308b\u8ef8\u690e\u690e\u5f13\u6839\u3068\u690e\u5f13\u306e\u653e\u5c04\u7dda\u5b66\u7684\u691c\u8a0e\uff09"}]}, "item_type_id": "14", "owner": "1", "path": ["461/848/849"], "permalink_uri": "http://hdl.handle.net/10091/00021521", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2019-06-14"}, "publish_date": "2019-06-14", "publish_status": "0", "recid": "20763", "relation": {}, "relation_version_is_last": true, "title": ["Radiographic measurements of C-2 in patients with atlas assimilation\uff08\u74b0\u690e\u7652\u5408\u75c7\u4f8b\u306b\u304a\u3051\u308b\u8ef8\u690e\u690e\u5f13\u6839\u3068\u690e\u5f13\u306e\u653e\u5c04\u7dda\u5b66\u7684\u691c\u8a0e\uff09"], "weko_shared_id": 3}
