“…For example, rates of occurrence and magnitudes of deformity after laminectomy have been reported. 7,22,23 This progressive kyphosis is widely considered to contribute to deterioration of clinical symptoms. 24,25 In open-door laminoplasty, preservation of the SS and IS ligaments has been recommended, 26 whereas in midsagittal laminoplasty, preservation of the NL has been recommended.…”

“…Miyazaki et al 11 reported on 46 patients with CSM or OPLL who had spinal instability or deformity. Their patients underwent French door laminoplasty and on-lay posterolateral bone graft placement, with an average follow-up of 53 months (range 12-118 months).…”

Object The objective of this systematic review was to use evidence-based medicine to examine the efficacy of cervical laminectomy and fusion for the treatment of cervical spondylotic myelopathy (CSM). Methods The National Library of Medicine and Cochrane Database were queried using MeSH headings and keywords relevant to cervical laminectomy, fusion, and CSM. Abstracts were reviewed, after which studies that met the inclusion criteria were selected. The guidelines group assembled an evidentiary table summarizing the quality of evidence (Class I–III). Disagreements regarding the level of evidence were resolved through an expert consensus conference. The group formulated recommendations which 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/Congress of Neurological Surgeons. Results Cervical laminectomy with fusion (arthrodesis) improves functional outcome in patients with CSM and ossification of the posterior longitudinal ligament (OPLL). Functional improvement is similar to laminectomy or laminoplasty for patients with CSM and OPLL. In contrast to laminectomy, cervical laminectomy with fusion it is not associated with late deformity (Class III). Conclusions Laminectomy with fusion (arthrodesis) is an effective strategy to improve functional outcome in CSM and OPLL.

“…29,30 There is a paucity of literature on the correlation between kyphotic deformity and clinical or neurologic outcomes and even some data suggesting there is no such correlation. 30,31,32 Augmenting a laminoplasty with modern instrumentation, however, has been shown to help preserve lordosis. 33 We had noticed progressive kyphosis in 12% (2/17) of our patients at four year follow-up.…”

Background Chronic compression of the cervical spinal cord leads to a clinical syndrome of cervical spondylotic myelopathy (CSM). Clinical symptoms of cervical spondylotic myelopathy (CSM) or cervical myeloradiculopathies result in spinal cord and root dysfunction. The primary aims of surgical intervention for multilevel myelopathy are to decompress the spinal cord and maintain stability of the cervical spine. Secondary aims are to minimize complications which include long-term pain and motion loss. Laminoplasty as either single-door or double-door technique and with/without instrumentation is an established mode of surgical treatment.The purpose of our study was to evaluate the result of single-door laminoplasty technique, supported with instrumented fixation in patients with multilevel degenerative cervical spondylotic myeloradiculopathy. MethodsA prospective and without control study has been conducted in the institution in 17 patients with CSM, operated by canal expansive single-door laminoplasty (Hirabayashi technique) between April 2010 to April 2015. These patients were followed up for at least 3 years with both clinical and radiographic evaluations. ResultsOn clinical evaluation, 15 of the 17 patients (87%) experienced relief of their symptoms. According to the Nurick classification, 11 patients' demonstrated improvement by one grade, two patients improved by two grades, two patients were unchanged and two had worsening of the Nurick grade. ConclusionsThe results of this study regarding the use of open-door laminoplasty with instrumented fixation suggest that this technique is a satisfactory alternative for cases of multilevel cervical spondylotic myelopathy without deformation.
