Abstract Background and Study Aim Cervical spondylotic myelopathy (CSM) is a common degenerative disease that mainly occurs in elder patients, leading to different degrees of neurological dysfunction. Spinal cord involvement is mainly distributed at the C3–C7 segments, but it may also involve up to the C2 level. This study aimed to assess the clinical efficacy and safety of open-door laminoplasty using a new extensor attachment-point reconstruction technique for treating CSM involving the C2 segment. Patients and Methods Fifty-nine patients with CSM involving the C2 segment and undergoing open-door laminoplasty were included in this retrospective study. Based on the titanium plate used in the operation, patients were divided into two groups, a reconstructed titanium plate fixation (RPF) group (n = 28) and a conventional titanium plate fixation (CPF) group (n = 31). Improvements in neurological function, cervical range of motion (ROM), cervical curvature index (CCI), preservation of posterior cervical muscle mass, and axial symptoms were compared between the two groups. Results There were no significant differences in operative time and intraoperative blood loss between the groups (p > 0.05). The Japanese Orthopaedic Association (JOA) score significantly increased in both groups postsurgery (p < 0.05); the neurological recovery rate was similar between the two groups (64.1 ± 13.3% vs. 65.9 ± 14.7%, p > 0.05). There was no significant loss of cervical ROM in either group (p > 0.05). The anteroposterior dural sac diameter at the C2 level was significantly enlarged in both groups (p < 0.05). Alternatively, CCI was significantly reduced in the CRP group (p < 0.05) but unchanged in the RPF group (p > 0.05). The cross-sectional area of the posterior cervical muscles was also significantly reduced in the CPF group (p < 0.05) but maintained in the RPF group (p > 0.05). Finally, axial symptoms were more severe in the CPF group than in the RPF group (p < 0.05). Conclusion Laminoplasty is an effective surgical procedure for CSM involving the C2 segment. The reconstructed titanium plate achieved superior maintenance of cervical curvature and reduced both muscle atrophy and severity of axial symptoms compared with titanium conventional plates.

Background: Cervical spondylotic myelopathy (CSM) is one of the most common diseases in the geriatric population. Decompressive laminectomy or laminoplasty is the predominant surgical procedure of choice, but there remains debate as to which procedure is optimal for managing CSM. Methods: Here, we retrospectively analyzed 64 patients with CSM undergoing laminectomy (39 patients) versus laminoplasty (25 patients). The data were collected included respective Japanese orthopedic association (JOA) scores, Nurick grades, and Visual analog scale (VAS) values preoperatively versus 12 months postoperatively. Results: The JOA score after 1 month improved in both groups utilizing laminectomy or laminoplasty. However, at 12 postoperative months, the JOA scores and Nurick grades showed greater improvement following laminoplasty, despite no differences in postoperative pain and complication rates. Conclusion: Patients with cervical spondylotic myelopathy undergoing laminoplasty (25 patients) showed better 12-month postoperative outcomes (JOA scores and Nurick grades) versus those having laminectomies (39 patients).

Cervical spondylotic myelopathy (CSM) is a degenerative process which may result in clinical signs and symptoms which require surgical intervention. Many treatment options have been proposed with various degrees of technical difficulty and technique sensitive benefits. We review laminoplasty as a motion-sparing posterior decompressive method. Current literature supports the use of laminoplasty for indicated decompression. We also decribe our surgical technique for an open-door, or “hinged”, laminoplasty.

Abstract Purpose To provide imaging evidence of the feasibility and clinical efficacy of a new full lamina back shift spinal canal enlargement technique by comparing its imaging parameters to those of single open-door miniature titanium plate internal fixation.Methods A retrospective analysis was conducted on 64 patients with multisegment cervical spondylotic myelopathy caused by cervical stenosis. Of these, 32 underwent the new full lamina back shift spinal canal enlargement technique (observation group), and 32 underwent single open-door miniature titanium plate internal fixation (control group). The CT data of both groups were imported into Mimics 17.0 software to measure the median sagittal diameter and cross-sectional area of the spinal canal. Photoshop CS5 was employed to measure the drift distance of the spinal cord on MR images to perform a comparative study of the imaging parameters from the two groups.Results The T2-weighted MR images in both groups showed continuous recovery of the cerebrospinal fluid signal in the C3–C7 range. The new full lamina back shift spinal canal enlargement technique was significantly superior to single open-door miniature titanium plate internal fixation with respect to the spinal canal cross-sectional area and the median sagittal diameter (P<0.05). No significant difference was detected in the drift distance of the spinal cord between the two groups (P>0.05).Conclusion The new full lamina back shift spinal canal enlargement technique achieved a thorough spinal canal decompression effect on imaging while ensuring a reasonable spinal drift distance and few surgical complications. The clinical curative effect of the new technique was precise.

Background: Cervical spondylotic myelopathy is a degenerative disease of the intervertebral disc and vertebral body of the spine that causes cervical spinal cord injury due to central vertebral canal stenosis. Its prevalence is higher in the elderly. Treatment is usually surgical when the spinal cord is affected either clinically with pyramidal release or radiologically with the altered spinal cord. Objective: The rationale of this study is to analyze the myelomalacia and the ossification of posterior longitudinal ligament as prognostic factors in the postoperative evolution of patients with cervical canal compression who underwent laminoplasty by open-door or french-door techniques. Methods: We performed a retrospective analysis of 18 surgical cases of spondylotic cervical myelopathy of the same senior neurosurgeon, using the chi-square test to analyze prognostic factors for patients’ postoperative evolution in the Nurick scale, after open-door or french-door laminoplasty. Results: The comparison between pre and postoperative showed an improvement of 71.43% of cases that did not have ligament ossification compared to 45.45% of cases that presented posterior longitudinal ligament ossification. Also, there was a better prognosis in patients without myelomalacia, as 71.43% of them improved their condition against only 45.45% improvement in those with myelomalacia. Conclusion: There is a need for further studies with larger samples to expressively prove that the presence of longitudinal ligament ossification and the previous presence of myelomalacia are factors of worse prognosis in the postoperative evolution of patients with cervical spondylotic myelopathy submitted to laminoplasty.

Abstract CERVICAL LAMINOPLASTY IS becoming a popular technique for the treatment of cervical myelopathy that is the result of multilevel canal stenosis. Many variations in this technique, which was originally created in Japan, have been developed, all with the goal of increasing canal space and reconstructing the posterior bony arch. We describe our extensive experience with this procedure for the treatment of cervical spondylotic myelopathy.
