“…Early diagnosis and accurate clinical evaluation are mandatory to achieve better treatment results. [1][2][3][4] The Japanese Orthopedic Association (JOA) developed a scoring system to quantify clinical impairment of patients with CSM, allocate them according to the degree of impairment, and thus suggest the best timing for surgery. Moreover, the JOA score for CSM is used worldwide in studies about CSM as a valuable tool for severity and outcome evaluation.…”

“…Moreover, the JOA score for CSM is used worldwide in studies about CSM as a valuable tool for severity and outcome evaluation. 1,[5][6][7] The JOA score for CSM has 4 domains that cover most myelopathy symptoms: (1) Motor dysfunction of upper extremity; (2) motor dysfunction of lower extremity; (3) sensory deficit (upper and lower extremities and trunk); and (4) sphincter dysfunction. The total score is obtained by summation of the 4 domains resulting in a maximum of 17 points.…”

Background: Cervical spondylotic myelopathy (CSM) is the most common degenerative dysfunction of the spinal cord in the cervical spine in patients older than 55 years. The Japanese Orthopedic Association developed a scoring system to quantify clinical impairment of CSM patients, allocate them according to the degree of impairment, and suggest best timing for surgery. The original version evaluates the upper limb motor function through the ability of feeding with chopsticks, which are not intrinsic in western populations. To compare severity and treatment improvement of any diseases, it is preferable to have modified and translated versions of questionnaires and scores closest to the original ones. The authors present a prospective cohort study to validate the 17-point Brazilian Portuguese translated version of the modified Japanese Orthopedic Association (mJOA-BR17) survey.Methods: Patients with CSM (n = 36) were allocated to the disease group, while age-and sex-matched healthy volunteers (n = 34) were recruited for the control group. Comparison of statistical analysis of mJOA-BR17 domains for each group was established. After the translation and adaptation of mJOA-BR17, the validation was made through application to the 2 groups.Results: There were statistical differences between groups in total mJOA-BR17 score (CSM, 14.

“…These changes ultimately lead to cervical stenosis. 7 Osteoarthritic degeneration of the cervical spine can cause irreversible damage to the spinal cord. Therefore, for moderate to severe CSM, surgery is the preferred treatment.…”

Effect of Titanium Miniplate Fixation on Hinge Fracture and Hinge Fracture Displacement Following Cervical Open-Door Laminoplasty

2020

Background: Cervical spondylotic myelopathy is a neuromotor disorder responsible for functional limitations and decreased daily activities. Expansive open-door laminoplasty is the widely accepted procedure for the treatment of multilevel cervical spondylotic myelopathy. Among the various fixation procedures to secure the open lamina, miniplate fixation provides better clinical and radiological outcomes. However, the immediate effects on hinge fracture and hinge fracture displacement following miniplate fixation have not been proven until now. The purpose of our study was to elucidate the impact of cervical open-door angle on the status of spinal cord expansion and hinge fracture, hinge fracture displacement, and the role of implants used during surgery. Methods: For this retrospective study, 122 patients who had undergone surgery from September 2016 to November 2017 with preoperative and postoperative radiographs were enrolled. Clinical and radiological outcomes were assessed before and after surgery. Results: There were no significant differences in demographics, surgery time, blood loss, medical comorbidities, or perioperative and postoperative complications between 2 groups. The recovery rate and Nurick score before and at the follow-up show no statistical significance between the 2 groups, P value. .05 (P ¼ .672) and P. .05 (P ¼ .553), respectively. The statistical analysis shows that the mean hinge fracture in the miniplate group with a cervical open angle .308 was 2.42 6 1.68 and with a ,308 open angle, 0.05 6 0.23; whereas, in the anchor group the mean hinge fracture in .308 cervical open angle was 2.227 6 2.50 and in ,308 was 0.409 6 0.503. The results revealed statistical significance between 2 implant groups, P ¼ .024 in the aspect of hinge fracture displacement and implant used. Conclusion: Laminoplasty by titanium miniplate fixation holds the laminae securely, prevents hinge fracture displacement, and promotes spinal cord expansion better than suture anchor fixation.
