Twenty patients had preoperative radicular pain, and CSA was diagnosed in 14 patients. The mean age at the time of surgery was 61 years (range 43\u201377 years). The follow-up period ranged from 2 to 6.5 years (mean 3.4 years). Foraminotomy was performed at 49 sites. Neurological improvement was evaluated using the Japanese Orthopaedic Association (JOA) scoring system; radicular pain and deltoid muscle strength were also evaluated clinically. Cervical lordosis, flexion\u2013extension angles, range of motion (ROM), and the angulation and the extent of vertebral slippage at the affected nerve root levels were measured preoperatively and at last follow-up examination.<\/jats:p>\n<jats:p>The mean rate of JOA score improvement was 67.2% (range 22.2\u2013100%). In all 20 patients, preoperative radicular pain completely resolved after surgery. In all 14 patients with CSA, deltoid muscle strength improved; in approximately 80% of these patients, there was either no muscle weakness or only slight weakness. The flexion angles and ROM significantly decreased at the time of the last follow-up examination (p = 0.0402 and 0.0196, respectively). No other items changed significantly.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>The aforementioned surgical procedure was safely completed and the surgical outcomes were satisfactory for CSRM including CSA. The instability (the angulation and the vertebral slippage) did not significantly change after surgery. This procedure yielded outstanding results and should be considered an option for cervical laminoplasty in the future.<\/jats:p><\/jats:sec>","DOI":"10.3171\/spi.2006.5.2.126","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T12:21:36Z","timestamp":1201177296000},"page":"126-132","source":"Crossref","is-referenced-by-count":15,"title":["Microsurgical posterior foraminotomy with laminoplasty for cervical spondylotic radiculomyelopathy including cervical spondylotic amyotrophy"],"prefix":"10.3171","volume":"5","author":[{"given":"Kunihiko","family":"Sasai","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Kansai Medical University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayuki","family":"Umeda","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kansai Medical University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takanori","family":"Saito","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kansai Medical University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroyuki","family":"Ohnari","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kansai Medical University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ei","family":"Wakabayashi","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kansai Medical University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirokazu","family":"Iida","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Kansai Medical University, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-0050126","series-title":"Spine","doi-asserted-by":"publisher","first-page":"196","DOI":"10.1097\/00007632-199601150-00007","article-title":"Laminoplasty with foraminotomy for coexisting cervical myelopathy and unilateral radiculopathy: a preliminary report","volume":"21","year":"1996"},{"key":"b2-0050126","series-title":"Neurol Clin","doi-asserted-by":"publisher","first-page":"495","DOI":"10.1016\/S0733-8619(18)31018-1","article-title":"Electrodiagnosis of radiculopathies","volume":"3","year":"1985"},{"key":"b3-0050126","series-title":"J Spinal Disord","first-page":"179","article-title":"Cervical laminoplasty: its role in the treatment of cervical radiculopathy","volume":"1","year":"1988"},{"key":"b4-0050126","series-title":"Spine","doi-asserted-by":"publisher","first-page":"774","DOI":"10.1097\/00007632-198807000-00011","article-title":"A comparison of anterior cervical fusion, cervical laminectomy, and cervical laminoplasty for the surgical management of multiple level spondylotic radiculopathy","volume":"13","year":"1988"},{"key":"b5-0050126","series-title":"Clin Orthop Relat Res","first-page":"94","article-title":"The surgical management of cervical spondylotic radiculopathy and myelopathy","volume":"239","year":"1989"},{"key":"b6-0050126","series-title":"Spine","doi-asserted-by":"publisher","first-page":"729","DOI":"10.1097\/00007632-198510000-00007","article-title":"Technical improvements and results of laminoplasty for compressive myelopathy in the cervical spine","volume":"10","year":"1985"},{"key":"b7-0050126","series-title":"Nippon Seikeigeka Gakkai Zasshi","first-page":"135","article-title":"[The clinical consideration of the dissociated motor loss syndrome (Kee-gan) in diseases of the cervical spine (author\u2019s transl).]","volume":"54","year":"1980"},{"key":"b8-0050126","series-title":"Spine","doi-asserted-by":"publisher","first-page":"448","DOI":"10.1097\/00007632-199802150-00008","article-title":"Cervical spondylotic amyotrophy.
