Clinical and functional results were estimated using the Japanese Orthopaedic Association score. The rate of recovery and the level of postoperative axial neck pain were also recorded. The pre- and post-operative alignment of the cervical spine (Ishihara curve index indicating lordosis of the cervical spine) and the range of movement (ROM) of the cervical spine were also measured. <\/jats:p><jats:p> The mean rate of recovery of the Japanese Orthopaedic Association score at final follow-up was 52.1% (sd 24.6) and significant axial pain was reported by 19 patients (25.3%). Axial pain was reported more frequently in patients with ossification of the posterior longitudinal ligament than in those with cervical spondylotic myelopathy (p = 0.027). A kyphotic deformity was not seen post-operatively in any patient. The mean ROM decreased post-operatively from 32.8\u00b0 (sd 12.3) to 16.2\u00b0 (sd 12.3) (p &lt; 0.001). The mean ROM ratio was 46.9% (sd 28.1) for all the patients. The mean ROM ratio was lower in patients with ossification of the posterior longitudinal ligament than in those with cervical spondylotic myelopathy (p &lt; 0.001). Compared to those with cervical spondylotic myelopathy, patients with ossification of the posterior longitudinal ligament had less ROM and more post-operative axial neck pain. <\/jats:p>","DOI":"10.1302\/0301-620x.93b1.24532","type":"journal-article","created":{"date-parts":[[2011,1,1]],"date-time":"2011-01-01T00:17:53Z","timestamp":1293841073000},"page":"68-72","source":"Crossref","is-referenced-by-count":36,"title":["Long-term results of tension-band laminoplasty for cervical stenotic myelopathy"],"prefix":"10.1302","volume":"93-B","author":[{"given":"T.","family":"Motosuneya","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Saitama Medical Center, 1981, Kamoda, Kawagoe, Saitama, 350-8550, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Maruyama","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Saitama Medical Center, 1981, Kamoda, Kawagoe, Saitama, 350-8550, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Saitama Medical Center, 1981, Kamoda, Kawagoe, Saitama, 350-8550, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.","family":"Tsuzuki","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Saitama Medical Center, 1981, Kamoda, Kawagoe, Saitama, 350-8550, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Saitama Medical Center, 1981, Kamoda, Kawagoe, Saitama, 350-8550, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"42","reference":[{"key":"R1","unstructured":"Kurokawa T, Tsuyama N, Tanaka H, et al.
