Purpose. To compare radiographic and clinical outcomes after anterior cervical discectomy in patients with cervical degenerative disc disease using PEEK cages or PMMA spacers with a minimum 1-year follow-up.Methods. Anterior cervical discectomy was performed in 107 patients in one or two levels using empty PEEK cages (51 levels), Sulcem PMMA spacers (49 levels) or Palacos PMMA spacers (41 levels) between January, 2005 and February, 2009. Bony fusion, subsidence, and sagittal alignment were retrospectively assessed in CT scans and radiographs at follow-up. Clinical outcome was measured using the VAS, NDI, and SF-36.Results. Bony fusion was assessed in 65% (PEEK cage), 57% (Sulcem), and 46% (Palacos) after a mean follow-up of 2.5 years. Mean subsidence was 2.3–2.6 mm without significant differences between the groups. The most pronounced loss of lordosis was found in PEEK cages (−4.1°). VAS was 3.1 (PEEK cage), 3.6 (Sulcem), and 2.7 (Palacos) without significant differences. Functional outcome in the PEEK cage and Palacos group was superior to the Sulcem group.Conclusions. The substitute groups showed differing fusion rates. Clinical outcome, however, appears to be generally not correlated with fusion status or subsidence. We could not specify a superior disc substitute for anterior cervical discectomy. This trial is registered withDRKS00003591.

This study was conducted to validate the safety and efficiency of biomimetic nanohydroxyapatite/polyamide 66 (n-HA/PA66) composite in animal model (rabbit) and report its application in anterior cervical discectomy and fusion (ACDF) for 4, 12, and 24 weeks. N-HA/PA66 composite was implanted into one-side hind femur defects and the control defects were kept empty as blank controls. A combination of macroscopic and histomorphometric studies was performed up to 24 weeks postoperatively and compared with normal healing. 60 cervical spondylosis myelopathy and radiculopathy patients who were subjected to ACDF using n-HA/PA66 and PEEK cage were involved in this study with six-month minimum follow-up. Their radiographic (cage subsidence, fusion status, and segmental sagittal alignment (SSA)) and clinical (VAS and JOA scales) data before surgery and at each follow-up were recorded and compared. Nanohydroxyapatite/polyamide 66 composite is safe and effective in animal experiment and ACDF.

Purpose: Anterior cervical discectomy and fusion is considered as a standard procedure for treating cervical degenerative disc disease. This retrospective study aimed to analyze the radiographic outcome of using a novel cushion titanium cage (Baui Z-Brace Dynamic Fusion Cage). Methods: Fifty-seven patients who received either single-, double-, or three-level interbody fusion surgeries were enrolled. Data from initial status after surgery and postoperative follow-ups for five years were obtained. The patients were divided into three groups according to different levels of cage implantation: 1-level ([Formula: see text]), 2-level ([Formula: see text]), and 3-level ([Formula: see text]). Follow-up time and fusion rate of radiographs were subjected to evaluation. Results: The lateral view of plain radiographs manifests no evident cage subsidence ([Formula: see text][Formula: see text]mm) and dislodgment in 1-, 2-, and 3-level cage implantation. The follow-up time is three years in 1-level and two years in 2- and 3-level. The CT scans at the final follow-up among different levels of cage implantation manifested bony fusion. The measurement of the Hounsfield unit indicates the bone growth inside the cage compared with control case, demonstrating solid bony fusion among groups at the final follow-up. Conclusions: The data confirm that the specialized Z-shaped structure of the cushion titanium cage may provide the interfragmentary motion stimulating innate bony fusion for sustained improvement.

Objective:  To assess the outcome of anterior cervical discectomy and fusion (ACDF) with PEEK cage. Material and Methods:  This prospective study was conducted in the Departments of Neurosurgery Prime Teaching Hospital and Irfan General Hospital Peshawar. Patients undergoing one level ACDF with PEEK cage fixation were enrolled in the study. Patients who needed multiple level ACDF or corpectomy with plating and redo cases were excluded from the study. A proforma, which included age, gender, address, level of prolapsed disc, sign and symptoms, pain score, MRI findings were filled. All patients were assessed on day of discharge and on follow-up visit after one month. Data was analyzed with SPSS version 22. Results:  Total 95 patients were included out of which 58 (61%) were male and 37 (39%) were female. Range of patients` Age was from 27 years to 64 years with 50.4 years mean age. Most patients (65%) had C6 radiculopathy. 58 patients (61%) had right sided radicular pain. 5 patients (5.26%) had radiculomyelopathy. C5 – C6 was the most common level operated (68 patients). Excellent results were achieved in 75 patients (79%) while satisfactory results in the rest of patients using Odom’s criteria. Bony fusion occurred in 92% of patients at 6 months. Conclusion:  ACDF with PEEK cage fixation is a safe and beneficial procedure in one level cervical prolapse disc disease

Abstract Background Biomechanical studies have demonstrated that uncovertebral joint contributes to segment mobility and stability to a certain extent. Simultaneously, osteophytes arising from the uncinate process are a common cause of cervical spondylotic radiculopathy (CSR). For such patients, partial uncinatectomy (UT) may be required. However, the clinical efficacy and sagittal alignment of partial UT during anterior cervical discectomy and fusion (ACDF) have not been fully elucidated. Methods A total of 87 patients who had undergone single level ACDF using a zero-profile device from July 2014 to December 2018 were included. Based on whether the foraminal part of the uncovertebral joint was resected or preserved, the patients were divided into the ACDF with UT group (n = 37) and the ACDF without UT group (n = 50). Perioperative data, radiographic parameters, clinical outcomes, and complications were compared between the two groups. Results The mean follow-up was 16.86 ± 5.63 and 18.36 ± 7.51 months in the ACDF with UT group and ACDF without UT group, respectively (p > 0.05). The average preoperative VAS arm score was 5.89 ± 1.00 in the ACDF with UT group and 5.18 ± 1.21 in the ACDF without UT group (p = 0.038). However, the average VAS arm score was 4.22 ± 0.64, 4.06 ± 1.13 and 1.68 ± 0.71, 1.60 ± 0.70 at 1 week post operation and at final follow up, respectively, (p > 0.05). We also found that the C2-7 SVA and St-SVA at the last follow-up and their change (last follow-up value − preoperative value) in the ACDF with UT group were significantly higher than ACDF without UT group (p < 0.05). No marked differences in the other cervical sagittal parameters, fusion rate or complications, including dysphagia, ASD, and subsidence, were observed. Conclusions Our result indicates that ACDF using a zero-p implant with or without partial UT both provide satisfactory clinical efficacy and acceptable safety. However, additional partial UT may has a negative effect on cervical sagittal alignment.

Background: Anterior cervical discectomy with fusion (ACDF) is challenging with respect to both patient selection and choice of surgical procedure.Objectives: The aim of this study was to evaluate the clinical outcome of anterior cervical discectomy and fusion with an artificial cage made of polyetheretherketoneMaterials & Methods: From January 2012 to January 2017, 80 consecutive patients referred to the Department of spine surgery, Bangabandhu Shekh Mujib Medical University were recruited for the study. Postoperative Clinical outcome assessed with Nurick scale for myelopathy, Odom's criteria for functional outcome and Visual Analogue Scale (VAS) for both neck and arm pain. Radiological fusion was assessed by X-ray. Operative complications were reported.Results: 36 patients were operated for one level discectomy and fusion with PEEK cages and 44 patients for two levels. There were 48 (60%) males and 32 (40%) females. The age of the patients ranged from 30-72 years, a mean ± SD 45 ± 8.34. At the 2 years clinical follow-up, there were significant post operative improvements of Nurick scale, and VAS comparative to preoperative record. According to Odom's criteria, 72/80 patients (90%) were graded excellent-good.Conclusion: Anterior cervical discectomy and fusion with polyetheretherketone (PEEK) cage is an effective treatment of cervical myelopathy having higher fusion rate and lack of donor site morbidity.KYAMC Journal Vol. 9, No.-1, April 2018, Page 32-34
