“…Except for the immediate stability, the clinical performance of an anterior cervical fixation device is also dependent on the long-term stability offered by the maintenance of the strength of the screw-vertebra fixation. Cases of delayed screw loosening or breakage have been reported in previously published studies [25,26]; in spite of successful spine arthrodesis, the incidence has been estimated as high as 5.2% [27]. To assess the morbidity of screw loosening, the stresses on the screw-vertebra interface were recorded in the present study, as too much stress on this region might be the leading cause in clinical series [23].…”

Background Anterior cervical plate and cage fixation system (ACPC) used in anterior cervical corpectomy and fusion (ACCF) is reported to incur excess complications. This study aimed to introduce integrated fixation cage (IFC) into ACCF to eliminate the anterior cervical plate (ACP)-related complications. Material/Methods One validated intact and 3 ACCF-simulated C3–C7 cervical spine models were developed. In ACCF models, C5 was corpectomied and fixed by IFC or ACPC. For each model, 1.0 Nm moments of flexion, extension, lateral bending, and torsion were imposed on the C3 vertebra. The range of motion (ROM) of each segment and the stress distribution on screw-vertebra interface, bone graft, and cage-endplate were recorded and analyzed. Results ROMs of C3–C7 were not different in any motion condition between IFC and ACPC models. The maximal von Mises stress on screw-vertebra interface of the IFC model was lower than that of the ACPC models in flexion, extension, and lateral bending, but higher in rotation. The maximal von Mises stress on bone graft of the IFC model was higher compared with the ACPC models, except in flexion. The IFC model showed a higher maximal von Mises stress on cage-endplate interface in all motion planes. Conclusions Based on finite element analysis, IFC provided identical C3–C7 construct stability as ACPC. Compared with ACPC, IFC showed better biomechanical performance on screw-vertebra interface and bone graft, but worse biomechanical performance on cage-endplate interface.

“…The route of the migration is the gastrointestinal trunk more frequently [6]. However, respiratory system is a very rare and alternative route for this complication, which was reported three times in the literature [7][8][9]. In this report, we present two complications of ACFS.…”

“…Rare cases such as aspiration and intrathoracic migration have also been reported in the literature [7][8][9]. The clinical presentation of foreign bodies migrating to the thorax involves acute airway obstruction and recurrent infections [9]. In the literature, one of the patients [8] had intermittent fever, and the other one [9] had coughing for 2 months.…”

“…There are several reports [2,21,22] referring to partial or total migration of the fixation device to gastrointestinal system via oral cavity and pharyngoesophageal perforation after ACFS. Rare cases such as aspiration and intrathoracic migration have also been reported in the literature [7][8][9]. The clinical presentation of foreign bodies migrating to the thorax involves acute airway obstruction and recurrent infections [9].…”

“…The clinical presentation of foreign bodies migrating to the thorax involves acute airway obstruction and recurrent infections [9]. In the literature, one of the patients [8] had intermittent fever, and the other one [9] had coughing for 2 months. In our second case, the patient had no complaints because of no verbal response due to tracheostomy and no fever or coughing was found.…”

Study design: A case report to emphasize the treatment of two different pharyngeal perforation cases, one of which occurs in early and one in the late post-operative period.Objective: We aimed to remind the risk of pharyngeal perforation which is a rare but life-threatening complication in anterior cervical fusion surgery.Summary and background data: Pharyngeal perforation is a serious complication of anterior cervical fusion surgery. If it is not diagnosed in the early period and the treatment is delayed, catastrophic consequences may occur which may cause death such as septicemia, mediastinitis, pneumonia and meningitis. Methods and results:We shared the presentation of our two cases. In the first case, pharyngeal perforation and spontaneous extrusion of the C2-C3 fixation device occurred after eight years from surgery. The fixation device removed and the pharyngeal wall repaired surgically. In the second case, one of the upper screws perforated the posterior pharyngeal wall in the early post-operative period and migrated to the right bronchus. The fixation device excision was achieved with rigid bronchoscopy, and the pharyngeal perforation was treated symptomatically. Conclusions:The patients who underwent anterior cervical fusion surgery that contains the C3 level are at risk of pharyngeal perforation. If the fixation device migrated to the thoracic cavity, it should be removed by interventional and/or surgical methods for the prevention of infection. The treatment of pharyngeal perforation after anterior cervical fusion surgery should be planned by multidisciplinary team that involves spine surgeons as well as otolaryngologists.
