Cervical Diseases Prediction Using LHVR Techniques

The stabilizing mechanisms of cervical spine spondylosis are involved in the degenerating segmentation vertebra,which often causes pain.Health of the individual is affected,both physically and mentally.Due to depression,nervous-ness,and psychological damages occur thereby losing their human activity func-tions.The nucleus pulposus of spinal disc herniation is prolapsed through a deficiency of annulusfibrosus.A jelly-like core part of the disc contains proteins that cause the tissues to become swollen when it touches the nucleus pulposus.The proposed Gradient Linear Classification(GLC)algorithm is used for the effi-cient automatic classification of disc degeneration herniation of Inter vertebral/vertebra in a cervical disc.Distance between the disc degeneration is classified through gradient operator and is estimated using the rotation of angles between the correlations.Specialists of the orthopedic spine are searching for high-preci-sion algorithms,which are achieved using proposed Linear Hybrid Vertebra Regression(LHVR)diagnostic techniques to identify the degree of cervical disc degeneration using an accurate location.Our experimental results have been used to determine a high range of classification in predicting the spinal cord which saves handling time and accomplishes high accuracy in detection.

Follow-up Study on the Motion Range after Treatment of Degenerative Disc Disease with the Bryan Cervical Disc Prosthesis

This study examined effect of a new intervertebral cervical disc prosthesis in relieving the neurological symptoms and signs, improving the patients＇ ability to perform daily activities, reducing pain, and maintaining the stability and segmental motion. From December 2003 to October 2004, 12 patients, who had received 14 replacements of cervical artificial discs, were followed-up for 2 to 8 months （with a mean of 5.2 months）. Of them 5 had cervical spondylotic myelopathy and 7 had cervical disc herniation. The patients included 7 males and 5 females, with their age ranging from 35 to 62 y and a mean of 50.3 y. Single-level replacements were performed in 10 cases and 2 cases received two-level replacement. Operation time of the single-level surgery averaged 130±50 rain and the time of two-level surgery was 165±53 min on average （from skin incision to skin suturing）. Neurological or vascular complications during or after surgery was not observed. Japanese Orthopedic Association scores （JOA scores） increased from 8.6 to 15.8 on average. There was no prothesis subsidence or excursion. Replaced segments were stable and the range of motion was partially restored, being 4.68° （3.6°-6.1°） in flexion and extension position and 3.51 ° （2.5°-4.6°）, 3.42° （2.6°-4.3°） in left and right bending position. No obvious loss of physiological curvature was noted. CT or MRI follow-up showed that excursion was less than 1.5 mm） in 2 of 14 levels and between 1.5 mm and 3 mm） in 1 of 14 levels. No ossification in the replaced levels was observed. It is concluded that satisfactory short-term results were achieved in the 12 cases of artificial disc replacements. Different from anterior cervical discectomy and fusion, the replacement could achieve quick functional recovery and did not lead to the movement limitation of cervical vertebrae. At least a 5-years follow-up was needed to assess the long-term effect of the prosthesis on its neighboring segments.

Anterior and Posterior Approach Results for Treatment of Cervical Myelopathy in the Elderly: A 10-Year Experience in a Mexican Institution

Introduction: Degeneration of the cervical spine (CDSD) prevalence is nearly 90% by the 7th decade. This is the first research that compares the outcomes between the Anterior Approach (AA) and Posterior Approach (PA) to cervical myelopathy (CM) in the elderly. Materials and Methods: A retrospective observational study of electronic health records at the Hospital Central Sur de Alta Especialidad (HCSAE), PEMEX from January 2010 to May 2020 with patients older than 60 years submitted to cervical surgery. For the analysis we elaborated two groups according to the surgical approach: AA vs PA;we analyzed the trans-operative behavior, the immediate outcome, and after 3 months, 6 months, and 1 year. Results: As a total of 145 patients, the prevalence of CM in elderly was the 63.8% with a median age of 69 (64 - 75) years. We found statistical differences in strength outcome only in the P3m (p = 0.011), for sensitivity we found major prevalence of affection in the PA group. We didn’t report a significant difference in the Neck Disability Index (NDI) at all measures, but the PA presented a major incapacity. The Nurick scale results were significant in all stages (p < 0.05);and presented improvement compared with presurgical period (p < 0.001). Discussion: Patients show significant improvements in outcome measures with either anterior or posterior surgery. Both approaches are highly efficacious in preventing neurologic deterioration and in most cases improve neurological function with appropriate postoperative management like rehabilitation, pain management, and psychological support. Conclusion: The patients submitted to surgical medullary decompression presented a favorable outcome despite the age and the higher prevalence of comorbidities;whereby we favor the surgical treatment in all patients in a case-to-case selection to generate a positive impact on functional outcomes.

Adjacent segment disease after anterior cervical decompression and fusion： analysis of risk factors on X-ray and magnetic resonance imaging

Background Adjacent segment disease （ASD） is common after cervical fusion.The aim of this study was to evaluate the risk factors for ASD on X-ray and magnetic resonance imaging （MRI）.Methods Patients included in this study had received revision surgeries after developing symptomatic ASD following anterior decompression and fusion.A control group that had not developed ASD was matched 1：1 by follow-up time and fusion segments.Plate-to-disc distances （PDDs）,developmental cervical canal stenosis on X-ray,cervical disc degeneration grading,and cervical disc bulge impingements on preoperative MRI were measured and compared between the ASD group and the control group.Results Thirty-four patients with complete radiographic data were included in the ASD group.The causative segments of ASD included nine cases of C3-4,18 cases of C4-5,three cases of C5-6,and four cases of C6-7.The ASD occurred at the upper adjacent segments in 26 patients and at the lower adjacent segments in eight patients.PDD distributions were similar between the ASD group and the control group.Developmental cervical canal stenosis was a risk factor for ASD,with an odd ratio value of 2.88.Preoperative cervical disc degenerations on MRI were similar between the ASD group and the control group.In the upper-level ASD group,the disc bulge impingement was （19.7±9.7）％,which was significantly higher than that of the control group of （11.8±4.8）％.Conclusions ASD was more likely to develop above the index level of fusion.Developmental cervical canal stenosis and greater disc bulge impingement may be risk factors for the development of ASD.
