Abstracts were reviewed and studies meeting the inclusion criteria were selected. The guidelines group assembled an evidentiary table summarizing the quality of evidence (Classes I\u2013III). Disagreements regarding the level of evidence were resolved through an expert consensus conference. The group formulated recommendations that contained the degree of strength based on the Scottish Intercollegiate Guidelines network. Validation was done through peer review by the Joint Guidelines Committee of the American Association of Neurological Surgeons and Congress of Neurological Surgeons.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Cervical laminoplasty has improved functional outcome in the setting of CSM or ossification of the posterior longitudinal ligament. Using the Japanese Orthopaedic Association scale score, ~ 55\u201360% average recovery rate has been observed (Class III). The functional improvement observed after laminoplasty may be limited by duration of symptoms, severity of stenosis, severity of myelopathy, and poorly controlled diabetes as negative risk factors (Class II). There is conflicting evidence regarding age, with 1 study citing it as a negative risk factor, and another not demonstrating this result.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Cervical laminoplasty is recommended for the treatment of CSM or ossification of the posterior longitudinal ligament (Class III).<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2009.1.spine08726","type":"journal-article","created":{"date-parts":[[2011,2,23]],"date-time":"2011-02-23T16:42:06Z","timestamp":1298479326000},"page":"157-169","source":"Crossref","is-referenced-by-count":64,"title":["Cervical laminoplasty for the treatment of cervical degenerative myelopathy"],"prefix":"10.3171","volume":"11","author":[{"given":"Paul G.","family":"Matz","sequence":"first","affiliation":[{"name":"Division of Neurological Surgery, University of Alabama, Birmingham, Alabama;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Anderson","sequence":"additional","affiliation":[{"name":"Departments of Orthopaedic Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael W.","family":"Groff","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Harvard Medical School and Beth Israel Deaconess Medical Center, Boston, Massachusetts;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert F.","family":"Heary","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Medicine and Dentistry of New Jersey\u2014New Jersey Medical School, Newark, New Jersey;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Langston T.","family":"Holly","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, David Geffen School of Medicine, University of California at Los Angeles, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael G.","family":"Kaiser","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, Neurological Institute, Columbia University, New York, New York;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Praveen V.","family":"Mummaneni","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of California at San Francisco, California;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy C.","family":"Ryken","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Iowa Hospitals and Clinics, Iowa City, Iowa;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanvir F.","family":"Choudhri","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Mount Sinai School of Medicine, New York, New York; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward J.","family":"Vresilovic","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Milton S.
