Thus, laminoplasty is not recommended in the presence of kyphotic alignment. Nevertheless, laminoplasty may be selected for myelopathy due to multiple-segment intervertebral disc herniation or ossification of posterior longitudinal ligament despite kyphotic alignment. This study examined whether cervical alignment influences surgical outcomes. Cervical alignment before the surgery was classified into lordosis and non-lordosis, and the non-lordosis group was subclassified into reducible and non-reducible groups to determine the change in cervical alignment before and after the surgery and to analyze its relationship with spinopelvic parameters. The lordosis group showed an increase in upper cervical motion (C0-2 Range of Motion (ROM), C0-2ROM\/C0-7ROM) after surgery, while the non-lordosis group exhibited a decrease in C2-7ROM and C0-7ROM. The C0-2ROM was maintained without any reduction in the reducible group, while there was no significant change in cervical alignment and ROM of the non-reducible group. None of these changes showed significant association with the spinopelvic parameters of other sites. However, having a non-reducible type non-lordosis is not a proper indication for laminoplasty, as it does not change the alignment after surgery. Therefore, cervical alignment and reducibility should be identified before surgery.<\/jats:p>","DOI":"10.3390\/jcm9030713","type":"journal-article","created":{"date-parts":[[2020,3,6]],"date-time":"2020-03-06T09:26:41Z","timestamp":1583486801000},"page":"713","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Analysis of Cervical Spine Alignment and its Relationship with Other Spinopelvic Parameters after Laminoplasty in Patients with Degenerative Cervical Myelopathy"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2882-4477","authenticated-orcid":false,"given":"Seok Woo","family":"Kim","sequence":"first","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"},{"name":"Department of Orthopaedic Surgery, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seung Bo","family":"Jang","sequence":"additional","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyung Min","family":"Lee","sequence":"additional","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong Hwan","family":"Lee","sequence":"additional","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min Uk","family":"Lee","sequence":"additional","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Sung","family":"Yee","sequence":"additional","affiliation":[{"name":"Spine Center, Hallym University Sacred Heart Hospital, Hallym University, 896 Pyeongchon-dong, Dongan-gu, Anyang-si, Gyeonggi-do 431-070, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"956","DOI":"10.1302\/0301-620X.77B6.7593114","article-title":"Long-term follow-up of cervical spondylotic myelopathy treated by canal-expansive laminoplasty","volume":"77","author":"Kimura","year":"1995","journal-title":"J.
