<p class="abstract"><strong>Background:</strong> Anterior cervical discectomy (ACD) was used for management of degenerative cervical disc disorders (DCDD) in previous days. Further research and developments in management of DCDD led to evolution of standard and widely used operative technique as anterior cervical discectomy and fusion (ACDF) by either anterior cervical plate (ACDF-ACP) with bone grafting or stand-alone cage (ACDF-SAC). There is less data available in literature regarding when and where to use ACDF-ACP and ACDF-SAC.</p><p class="abstract"><strong>Methods:</strong> The study was conducted on 20 patients operated in Government Medical College and Hospital and Pacific Hospital and Research Centre, Aurangabad from June 2018 to March 2020. These patients divided into group A - 10 patients, operated by ACDF-SAC which are further divided as group Aa - 6 patients - operated for single level ACDF-SAC and group Ab - 4 patients - operated for two level ACDF-SAC, group B - 10 patients, operated by ACDF-ACP which are further divided as group Ba - 5 patients - operated for single level ACDF-ACP and group Bb - 5 patients - operated for two level ACDF-ACP. Patients evaluated preoperatively and postoperatively using X-ray cervical spine anteroposterior (AP) and lateral views, MRI cervical spine, visual analogue scale (VAS) for pain, Robinson’s criteria and Cobb’s angle.<strong></strong></p><p class="abstract"><strong>Results:</strong> In our study we found, ACDF-SAC has small incision size, less intraoperative time, easy to carry out for surgeons, less intraoperative complications and better clinical outcome as compared to ACDF-ACP. Whereas only radiological results were better in ACDF-ACP than ACDF-SAC.</p><p class="abstract"><strong>Conclusions:</strong> ACDF-SAC is superior to ACDF-ACP for appropriately selected patients and in well experienced hands.</p>

Object Although smoking has been shown to negatively affect fusion rates in patients undergoing multilevel fusions of the cervical and lumbar spine, the effect of smoking on fusion rates in patients undergoing single-level anterior cervical discectomy and fusion (ACDF) with allograft and plate fixation has yet to be thoroughly investigated. The objective of the present study was to address the effect of smoking on fusion rates in patients undergoing a 1-level ACDF with allograft and a locked anterior cervical plate. Methods This study is composed of patients from the control groups of 5 separate studies evaluating the use of an anterior cervical disc replacement to treat cervical radiculopathy. For each of the 5 studies the control group consisted of patients who underwent a 1-level ACDF with allograft and a locked cervical plate. The authors of the present study reviewed data obtained in a total of 573 patients; 156 patients were smokers and 417 were nonsmokers. A minimum follow-up period of 24 months was required for inclusion in this study. Fusion status was assessed by independent observers using lateral, neutral, and flexion/extension radiographs. Results An overall fusion rate of 91.4% was achieved in all 573 patients. A solid fusion was shown in 382 patients (91.6%) who were nonsmokers. Among patients who were smokers, 142 (91.0%) had radiographic evidence of a solid fusion. A 2-tailed Fisher exact test revealed a p value of 0.867, indicating no difference in the union rates between smokers and nonsmokers. Conclusions The authors found no statistically significant difference in fusion status between smokers and nonsmokers who underwent a single-level ACDF with allograft and a locked anterior cervical plate. Although the authors do not promote tobacco use, it appears that the use of allograft with a locked cervical plate in single-level ACDF among smokers produces similar fusion rates as it does in their nonsmoking counterparts.

Object The authors report the short-term results of anterior cervical discectomy and interbody fusion performed via an endoscopic approach. Methods Thirty-six patients who underwent anterior cervical discectomy and fusion (ACDF) performed using endoscopic surgery were selected for this study. The indications for surgery were cervical disc herniation caused by neck injury, spondylotic myelopathy, cervical radiculopathy, and solitary ossification of the posterior longitudinal ligament (OPLL). The involved levels included C3–4, C4–5, C5–6, and C6–7. The working channel was inserted through a 20-mm transverse incision, the protruding discs or area of OPLL were excised for complete decompression, and then an appropriate intervertebral polyetheretherketone fusion cage was implanted. Results The time spent in surgery was 120 minutes on average (range 50–150 minutes), and the mean blood loss was 55 ml (range 20–140 ml). There were no intraoperative complications and no symptoms of irritation in the laryngopharynx after surgery. However, postoperative hemorrhage of the incision occurred in 1 case. The follow-up period ranged from 26–50 months (mean 38.5 months). Postoperative Japanese Orthopaedic Association and visual analog scale scores improved significantly. Conclusions Endoscopic surgery for ACDF can produce satisfactory results in patients with cervical disc herniation, cervical myelopathy, or radiculopathy. The optimal levels for this procedure are C4–5 and C5–6. Compared with a traditional approach, this technique has great advantages in terms of cosmetic results, intraoperative visualization, and postoperative recovery course. Nevertheless, every precaution should be taken to avoid possible complications, such as postoperative hemorrhage.

OBJECTIVE The use of osteobiologics, engineered materials designed to promote bone healing by enhancing bone growth, is becoming increasingly common for spinal fusion procedures, but the efficacy of some of these products is unclear. The authors performed a retrospective, multi-institutional study to investigate the clinical and radiographic characteristics of patients undergoing single-level anterior cervical discectomy with fusion performed using the osteobiologic agent Osteocel, an allograft mesenchymal stem cell matrix. METHODS The medical records across 3 medical centers and 12 spine surgeons were retrospectively queried for patients undergoing single-level anterior cervical discectomy and fusion (ACDF) with the use of Osteocel. Pseudarthrosis was determined based on CT or radiographic imaging of the cervical spine. Patients were determined to have radiographic pseudarthrosis if they met any of the following criteria: 1) lack of bridging bone on CT obtained > 300 days postoperatively, 2) evidence of instrumentation failure, or 3) motion across the index level as seen on flexion-extension cervical spine radiographs. Univariate and multivariate analyses were then performed to identify independent preoperative or perioperative predictors of pseudarthrosis in this population. RESULTS A total of 326 patients met the inclusion criteria; 43 (13.2%) patients met criteria for pseudarthrosis, of whom 15 (34.9%) underwent revision surgery. There were no significant differences between patients with and those without pseudarthrosis, respectively, for patient age (54.1 vs 53.8 years), sex (34.9% vs 47.4% male), race, prior cervical spine surgery (37.2% vs 33.6%), tobacco abuse (16.3% vs 14.5%), chronic kidney disease (2.3% vs 2.8%), and diabetes (18.6% vs 14.5%) (p > 0.05). Presence of osteopenia or osteoporosis (16.3% vs 3.5%) was associated with pseudarthrosis (p < 0.001). Implant type was also significantly associated with pseudarthrosis, with a 16.4% rate of pseudarthrosis for patients with polyetherethereketone (PEEK) implants versus 8.4% for patients with allograft implants (p = 0.04). Average lengths of follow-up were 27.6 and 23.8 months for patients with and those without pseudarthrosis, respectively. Multivariate analysis demonstrated osteopenia or osteoporosis (OR 4.97, 95% CI 1.51–16.4, p < 0.01) and usage of PEEK implant (OR 2.24, 95% CI 1.04–4.83, p = 0.04) as independent predictors of pseudarthrosis. CONCLUSIONS In patients who underwent single-level ACDF, rates of pseudarthrosis associated with the use of the osteobiologic agent Osteocel are higher than the literature-reported rates associated with the use of alternative osteobiologics. This is especially true when Osteocel is combined with a PEEK implant.

Objectives: The aim of this study is to compare patients undergoing single level anterior cervical discectomy without fusion (ACD) versus anterior cervical discectomy with fusion (ACDF). Methods: A retrospective analysis of 50 patients with degenerative cervical spondylosis of them 25 had undergone ACD without fusion and remaining 25 undergone ACDF at either C4-C5, C5- C6 level or at C6-C7 level. Results: The kinematic analysis included the range of motion, intervertebral angulations, anteroposterior translation and disc height assessed for the cervical functional spinal units at the operated level and adjacent levels. At the operated level of C4-C5, C5-C6 and C6-C7, the range of motion and the translation were minimal in the anterior cervical discectomy without fusion (ACD) group, but absent in the cervical discectomy with fusion (ACDF) group. The superior adjacent levels range of motion and the translation were greater in the ACDF group compared with the ACD group. But both groups had almost similar results in term of hospital stay, mean time for improvement and patient satisfaction. Conclusion: The clinical results of anterior cervical discectomy without fusion (ACD) and anterior cervical discectomy with fusion (ACDF) were comparable. In cervical discectomy without fusion, the elastic fibrous intradiscal scar at the operated level allows a small degree of mobility and the adjacent cervical levels are not overstressed. Fusion is not routinely required in single level cervical disc herniation until it is associated with instability, loss of cervical lordosis, hard disc, osteophytic bar and multi-segmental disease. So ACD is a better option in single level cervical disc disorder than ACDF. J Dhaka Medical College, Vol. 27, No.1, April, 2018, Page 29-35
