After surgery, in 27 patients (81.8%) different levels of clinical improvement were demonstrated, and in five of them (15%) full recovery was observed. The Japanese Orthopaedic Association score increased from 5 to 12 (mean 9.8) preoperatively to 8 to 14 (mean 11.6) postoperatively. At 1-year follow up, the N13 cervical response was restored in nine (75%) of 12 patients with isolated presurgical abnormality and in 57.1% of those with combined abnormalities of both N13 and P14 response. Although significant clinical improvement was observed in 82% of the cases, in 24 of 33 patients MEP abnormalities persisted at least at one explored level.<\/jats:p>\n<jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic> Of several laminoplasty techniques, the one described here offers some advantages: preservation of biomechanical function of posterior muscular\u2014ligamentous complex, prevention of laminar collapse, smaller degrees in reduction of range of cervical motion, stabilization of the spine with no postoperative malalignment, and maintenance of decompressive effect that avoids recurrent stenosis. Neurophysiological studies sometimes clarified neurological disorders that were only suspected on the basis of history and\/or clinical examination, leading to early diagnosis.<\/jats:p>","DOI":"10.3171\/spi.2000.92.1.0038","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:49:51Z","timestamp":1241711391000},"page":"38-43","source":"Crossref","is-referenced-by-count":21,"title":["Open-door laminoplasty for cervical stenotic myelopathy: surgical technique and neurophysiological monitoring"],"prefix":"10.3171","volume":"92","author":[{"given":"Romeo","family":"Roselli","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angelo","family":"Pompucci","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesco","family":"Formica","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Domenico","family":"Restuccia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vincenzo","family":"Di Lazzaro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Massimiliano","family":"Valeriani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Massimo","family":"Scerrati","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"217","DOI":"10.3171\/jns.1988.68.2.0217","article-title":"Myelopathic cervical spondylotic lesions demonstrated by magnetic resonance imaging.","volume":"68","author":"Al-Mefty","year":"1988"},{"key":"b2","series-title":"Electroencephalogr Clin Neurophysiol","doi-asserted-by":"publisher","first-page":"227","DOI":"10.1016\/0013-4694(80)90217-5","article-title":"Short latency somatosensory evoked potentials: studies in patients with focal neurological disease.","volume":"49","author":"Anziska","year":"1980"},{"key":"b3","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","author":"Baba","year":"1996"},{"key":"b4","series-title":"Paraplegia","first-page":"25","article-title":"Cervical laminoplasty in patients with ossification of the posterior longitudinal ligaments.","volume":"33","author":"Baba","year":"1995"},{"key":"b5","series-title":"J Neurol","doi-asserted-by":"publisher","first-page":"626","DOI":"10.1007\/BF00878657","article-title":"Lordotic alignment and posterior migration of the spinal cord following en bloc open-door laminoplasty for cervical myelopathy: a magnetic resonance imaging study.","volume":"243","author":"Baba","year":"1996"},{"key":"b6","series-title":"J Bone Joint Surg (Am)","doi-asserted-by":"publisher","first-page":"119","DOI":"10.2106\/00004623-199301000-00016","article-title":"Cervical spondylotic myelopathy.","volume":"75","author":"Bernhardt","year":"1993"},{"key":"b7","series-title":"Spine","doi-asserted-by":"publisher","first-page":"151","DOI":"10.1097\/00007632-197706000-00008","article-title":"Cervical spondylosis with moderate to severe myelopathy: a report of seventeen cases treated by Robinson anterior cervical discectomy and fusion.","volume":"2","author":"Bohlman","year":"1977"},{"key":"b8","series-title":"Brain","doi-asserted-by":"publisher","first-page":"187","DOI":"10.1093\/brain\/75.2.187","article-title":"Neurological manifestations of cervical spondylosis.","volume":"75","author":"Brain","year":"1952"},{"key":"b9","series-title":"Spine","doi-asserted-by":"publisher","first-page":"2135","DOI":"10.1097\/00007632-199510000-00012","article-title":"Motor and somatosensory conduction in cervical myelopathy and radiculopathy.","volume":"20","author":"Chistyakov","year":"1995"},{"key":"b10","series-title":"Electroencephalogr Clinical Neurophysiol","doi-asserted-by":"publisher","first-page":"311","DOI":"10.1016\/0168-5597(92)90107-M","article-title":"The contribution of magnetic stimulation of the motor cortex to the diagnosis of cervical spondylotic myelopathy.
