Objective. To investigate the clinical effects of posterior laminectomy and decompression plus lateral mass screw-rod internal fixation for the treatment of multisegment cervical spinal canal stenosis and the improvement of cervical curvature and range of motion in patients. Methods. A total of 68 patients with multisegment cervical spinal stenosis who were treated in our hospital from January 2019 to June 2020 were selected and randomly divided into the control group and the observation group according to the random number table, with 34 patients in each group. The patients in the control group were treated with traditional posterior cervical open-door laminoplasty with silk suture fixation, while those in the observation group were treated with posterior cervical laminectomy and decompression plus lateral mass screw-rod internal fixation. The perioperative index of patients in the two groups was recorded, and the clinical efficacy of patients was evaluated. The patient’s JOA score, cervical physiological curvature, and cervical range of motion were evaluated. The occurrence of complications was recorded during follow-up. Results. The amount of intraoperative bleeding and postoperative rehabilitation training time in the observation group was less than that in the control group ( P < 0.05 ). There was no significant difference in operation time between the two groups ( P > 0.05 ). The total effective rate of the observation group was significantly higher than that of the control group ( P < 0.05 ). The JOA scores at 1 week, 6 months, and 12 months after operation in the observation group were higher than those in the control group ( P < 0.05 ). The physiological curvature of cervical spine in the observation group at 1 week, 6 months, and 12 months after operation was higher than that in the control group ( P < 0.05 ). The cervical range of motion at 12 months after operation in the observation group was significantly higher than that in the control group ( P < 0.05 ). The incidence of postoperative complications in patients of the observation group was significantly lower than that of the control group ( P < 0.05 ). Conclusion. Posterior laminectomy and decompression plus lateral mass screw-rod internal fixation can help patients to improve various clinical symptoms caused by nerve compression and obtain better improvement of cervical curvature and range of motion. It is an ideal surgical method for the treatment of multisegment cervical spinal canal stenosis, and it is conducive to improving the clinical efficacy of patients.

Abstract Background Increased spinal cord motion has been proven to be a relevant finding within spinal canal stenosis disclosed by phase-contrast MRI (PC-MRI). Adapted PC-MRI is a suitable and reliable method within the well deliberated setting. As the decision between conservative and operative treatment can be challenging in some cases, further diagnostic marker would facilitate the diagnostic process. We hypothesize that increased spinal cord motion will correlate to clinical course and functional impairment and will contribute as a new diagnostic marker. Methods A monocentric, prospective longitudinal observational trial on cervical spinal canal stenosis will be conducted at the University Medical Center Freiburg. Patients (n = 130) with relevant cervical spinal canal stenosis, being defined by at least contact to the spinal cord, will be included. Also, we will examine a control group of healthy volunteers (n = 20) as proof-of-principle. We will observe two openly assigned branches of participants undergoing conservative and surgical decompressive treatment (based on current German Guidelines) over a time course of 12 month, including a total of 4 visits. We will conduct a broad assessment of clinical parameters, standard scores and gradings, electrophysiological measurements, standard MRI, and adapted functional PC-MRI of spinal cord motion. Primary endpoint is the evaluation of an expected negative correlation of absolute spinal cord displacement to clinical impairment. Secondary endpoints are the evaluation of positive correlation of increased absolute spinal cord displacement to prolonged evoked potentials, prediction of clinical course by absolute spinal cord displacement, and demonstration of normalized spinal cord motion after decompressive surgery. Discussion With the use of adapted, non-invasive PC-MRI as a quantitative method for assessment of spinal cord motion, further objective diagnostic information can be gained, that might improve the therapeutic decision-making process. This study will offer the needed data in order to establish PC-MRI on spinal cord motion within the diagnostic work-up of patients suffering from spinal canal stenosis.

SummaryThis report describes the management of clinically significant, single level cervical spinal canal stenosis associated with articular facet hypertrophy in a three-year-old Great Dane dog, by combined surgical decompression and spinal stabilization. Spinal column stabilization was achieved by ventral application of two String of Pearls locking plates and subsequent decompression was accomplished by unilateral facetectomy. The six-month postoperative reassessment examination confirmed satisfactory clinical outcome with a complete return to normal activity, resolution of neurological deficits and maintenance of implant positioning.
