Application of a modified surgical position in anterior approach for total cervical artificial disc replacement

BACKGROUND Total cervical artificial disc replacement(TDR)has been considered a safe and effective alternative surgical treatment for cervical spondylosis and degenerative disc disease that have failed to improve with conservative methods.Positioning the surgical patient is a critical part of the procedure.Appropriate patient positioning is crucial not only for the safety of the patient but also for optimizing surgical exposure,ensuring adequate and safe anesthesia,and allowing the surgeon to operate comfortably during lengthy procedures.The surgical posture is the traditional position used in anterior cervical approach;in general,patients are in a supine position with a pad under their shoulders and a ring-shaped pillow under their head.AIM To investigate the clinical outcomes of the use of a modified surgical position versus the traditional surgical position in anterior approach for TDR.METHODS In the modified position group,the patients had a soft pillow under their neck,and their jaw and both shoulders were fixed with wide tape.The analyzed data included intraoperative blood loss,position setting time,total operation time,and perioperative blood pressure and heart rate.RESULTS Blood pressure and heart rate were not significantly different before and after body positioning in both groups(P>0.05).Compared with the traditional position group,the modified position group showed a statistically significantly longer position setting time(P<0.05).However,the total operation time and intraoperative blood loss were significantly reduced in the modified position group compared with the traditional position group(P<0.05).CONCLUSION The clinical outcomes indicated that total operation time and intraoperative blood loss were relatively lower in the modified position group than in the traditional position group,thus reducing the risks of surgery while increasing the position setting time.The modified surgical position is a safe and effective method to be used in anterior approach for TDR surgery.

Total Spondylectomy of C2 and Circumferential Reconstruction via Combined Anterior and Posterior Approach to Cervical Spine for Axis Tumor Surgery

As a result of the complex anatomy in upper cervical spine, the operative treatment of axis neoplasms is always complicated. Although the procedure for the second cervical vertebra （C2） surgery had been described previously in diverse approaches and reconstruction forms, each has its own limita- tions and restrictions that usually result in less satisfactory conclusions. The purpose of this study was to evaluate the operation efficacy for axis tumors by using a combined anterior （retropharyngeal） cervical and posterior approach in achieving total resection of C2 and circumferential reconstruction. Eight con- secutive C2 tumor patients with mean age of 47.6 years in our institute sequentially underwent vertebra resection and fixation through aforementioned approach from Jan. 2006 to Dec. 2010. No surgical mor- tality or severe morbidity occurred in our group. In terms of complications, 2 cases developed transient difficulty in swallowing liquids （one of them experienced dysphonia） and 1 developed cerebrospinal fluid leakage （CSFL） that was resolved later. During a mean follow-up period of 31.9 months, the visual analogue scale （VAS） and Japanese orthopedic association （JOA） score revealed that the pain level and neurological function in all patients were improved postoperatively, and there was no evidence of fixa- tion failure and local recurrence. It is concluded that the anterior cervical retropharyngeal approach permits a visible exposure to facilitate the C2 vertebra resection and perform an effective anterior re- construction at the same time. The custom-made mesh cage applied in our cases can be acted as a firm and convenient implant in circumferential fixation.

Effect of cervical spine surgery on the biomechanics of the cervical spine

In clinical practice,cervical spine surgery inevitably alters the original physiological structure of the cervical spine,thus causing changes in the original biomechanical properties of the cervical spine.The biomechanical properties of the cervical spine are particularly significant as it is an essential structure that supports the head and connects the trunk.Different cervical spine surgery options can have different effects on the biomechanics of the cervical spine.Therefore,this review will discuss recent research advances on the effects of cervical spine surgery on cervical spine biomechanics.We hope that this review will provide some theoretical basis for future studies on the biomechanical effects of cervical spine surgery on the cervical spine.

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.

SELECTION OF SURGICAL APPROACH TO TREAT TRAUMATIC INSTABILITY OF SUBAXIAL CERVICAL SPINE

Objective To evaluate the clinical outcomes of surgical therapy in treating traumatic instability of subaxial cervical spine through either anterior or posterior approach. Methods According to the Allen-Fergurson's classification, we retrospectively studied 42 cases of traumatic instability of subaxial cervical spine through either anterior or posterior surgical reconstruction. Patients requiring approach for either reduction or decompression were not included. Results The average follow-up interval was 3 years and 2 months. The anterior and posterior reconstructions were 24 and 18 cases, respectively. Before operation, the average scores of JOA and VAS were: 12.1 and 6.9 for anterior group, and 12.3 and 7.2 for posterior group. At the final assement, the scores of JOA and VAS improved to 16.0 and 2.2 for anterior group, and 15.7 and 2.6 for posterior group. The average ASIA motor scores of anterior and posterior group improved to 68.2 and 65.5 at the final follow-up from 58.4 and 59.7 before operation, respectively. The ASIA grade (A-E) was converted to a numeric score. The average scores before operation in the anterior and posterior group were 3.3 and 3.4, and increased to 3.8 and 3.7 at the final follow-up. After operation, there were different extent improvements of average radiological parameter, such as Cobb angle, vertebral body translation and disc height ratio. The average operation time and blood losing were 122 min and 125 mL for anterior group, and 153 min and 287 mL for posterior group. Fusion was achieved in all patients and 4 and 2 complications occurred at the anterior or posterior group. Conclusion The results showed that there were no obvious difference in parameters, such as neurological assements, functional grades, fusion rate, operation time and blood losing, between anterior and posterior group, except the virtues of anterior group in reconstruction and maintaining physiologic cervical lordosis and intervertrbal disc height occurred.

Multilevel oblique corpectomies as an effective surgical option to treat cervical chordoma in a young girl

Chordomas are malignant tumors arising from notochordal remnants. They are the most frequent tumors of the spine after plasmacytomas. Only 6% of chordomas are localized to the cervical level. In young patients, chordomas are rare and unpredictable. Despite this, the treatment of choice remains the total resection, as much as possible, followed by proton beam radiation. This case was managed using a precarotid and retrocarotid approach at the same time. The tumor was completely resected with the edges free from disease. The cervical spine was stabilized with an anterior plating C2-C4. Eighteen months after surgery the patient is still free from illness. Multilevel oblique corpectomies are an available and safe option for the treatment of upper cervical chordomas.

有限元法预测颈椎前路椎间盘切除融合螺钉置入位置对内固定稳定性的影响

背景:在颈椎前路椎间盘切除融合过程中,螺钉放置角度会影响内固定系统的稳定性。目的:有限元分析法预测不同螺钉放置角度对颈椎前路椎间盘切除融合过程中内固定系统应力的影响,寻找螺钉最佳放置角度。方法:采用三维重建法建立颈椎力学模型,模拟颈椎侧弯、直立和前屈等3种不同的工况。在SolidWorks 2017软件中,建立颈椎前路钢板和螺钉模型,根据螺钉的不同放置角度建模,a为内侧偏移,b为理想位置,c为外侧偏移,d为向下偏移,e为向上偏移。观察不同螺钉放置角度下内固定的应力分布,并记录其应力和位移。结果与结论:①构建全颈椎及前路钢板置入后的有限元模型,在相同工况下,钢板上螺钉的不同置入角度对脊柱生物力学改变无明显差别;②但微观数值显示,在侧弯工况下,向外偏移(c)螺钉位置的抗侧弯性能最好;在直立工况下,向下偏移(d)螺钉承载效果最好;在反屈工况下,向外偏移(c)螺钉抗屈效果最好;③在不同的运动工况下,内固定装置的固定效果是相对稳定的;当螺钉向内侧、外侧、向下或向上放置时,3种工况下的内固定效果相差10%,但位移变化较小;这说明在临床实际操作中同时满足承重、抗弯、抗屈的最佳螺钉位置是不存在的;④提示颈椎前路间盘切除融合术中钢板螺钉的置入方向对颈椎的力学稳定性影响不大;在颈椎侧屈、直立、前屈运动时,不同方向的螺钉角度对颈椎内固定装置的稳定性影响不大;因此在临床手术中无需刻意追求螺钉的置入方向。

Surgical resection of intradural extramedullary tumors in the atlantoaxial spine via a posterior approach

BACKGROUND The anatomical features of the atlantoaxial spine increase the difficulty of complete and safe removal of atlantoaxial intradural extramedullary(IDEM)tumors.Studies concerning surgical interventions via a posterior approach are limited.AIM To investigate the safety and efficacy of atlantoaxial IDEM tumor resection using a one-stage posterior approach.METHODS We retrospectively analyzed clinical databases for one-stage atlantoaxial IDEM tumor resection via a posterior approach between January 2008 and January 2018.The analyzed data included tumor position,histopathological type,pre-and postoperative Japanese Orthopedic Association(JOA)scores and Nurick grades,postoperative complication and recurrence status.RESULTS A total of 13 patients who underwent C1-C2 Laminectomy and/or unilateral facetectomy via the posterior approach were enrolled in the study.In all cases reviewed,total tumor resection and concomitant C1-C2 fusion were achieved.The average follow-up was 35.3±6.9 mo(range,26-49 mo).A statistically significant difference was noted between the preoperative JOA score(11.2±1.1)and the score at the last final follow-up(15.6±1.0)(P<0.05).A statistically significant difference was noted between the preoperative Nurick grade(2.3±0.9)and that at the last follow-up(1.2±0.4)(P<0.05).However,no statistically significant difference was noted between the preoperative and last follow-up C1-2 Cobb angle and C2-7 Cobb angle(P>0.05).No mortalities,severe complications or tumor recurrence were observed during the follow-up period.CONCLUSION Total resection of atlantoaxial IDEM tumors is feasible and effective via a posterior approach.Surgical reconstruction should be considered to avoid iatrogenic kyphosis and improve spinal stability and overall clinical outcomes.
