No screw loosening, implant migration or implant failures, atlantoaxial redislocation, or signs of instability were observed in any of the patients during the follow-up period. Subaxial cervical spine fracture is commonly seen with high impact accidents such as motor vehicle accidents. C2 fractures typically occur due to a combination of compression, hyperflexion, and hyperextension. Furthermore, the average improvement in neurological function was 87.4 %. Pathophysiology C1 fractures typically result from axial loading. The average of patients JOA scores at the final follow-up was significantly higher than that of their preoperative scores. The patients were followed up for an average of 19.6 months (ranged from 9 to 36 months). The purpose was to investigate mortality, complication, and fusion rates in patients with odontoid fracture, depending on age, comorbidities, fracture type, and treatment. Bony fusion was seen in all patients postoperatively. Abstract Purpose The French Society of Spine Surgery (SFCR) conducted a prospective epidemiologic multicenter study. The majority of C2 fracture types are type-II dens fractures. Type III: A fracture occurring in the body of the axis underlying the dens. C2 fractures are associated with a 20 and 40 increased risk of mortality within 3 months and 2 years, respectively. Type I: A fracture of the upper part of the process (the tip.) Type II: A Fracture at the base of the dens. Neurologic status was evaluated using the Japanese Orthopaedic Association (JOA) scoring system.Īll seven patients had complete release, and satisfactory reduction. Epidemiology The incidence of C2 fractures increased 135 from 2000 to 2011 in the Medicare population. C1-C2 were then fixed through pedicle screws and rods, and then fused posteriorly by single stage. The present study was carried out to focus on the nuances involved. Anterior atlantoaxial release was performed through anterior transoral approach, followed by partial resection of the odontoid process. Introduction : Odontoid fractures constitute 9-20 of all adult cervical spine fractures. This study included seven cases of IAAD caused by odontoid fracture malunion, collected from January 2008 to January 2011. We also evaluated the clinical efficacy of this surgery. This study aimed to introduce a surgical method of transoral anterior release, odontoid partial resection, and reduction with sequential posterior fusion for the treatment of IAAD caused by odontoid fracture malunion. Odontoid fractures can happen at any age, but the injury occurs most often in adolescents or older patients. However, no study has reported the surgical method for the management of IAAD caused by odontoid fracture malunion. The odontoid process is a unique peg-like bony structure of the C2 (second cervical) vertebra in the neck that physicians sometimes refer to as the dens ( Fig. Several techniques have been introduced to manage irreducible atlantoaxial dislocation (IAAD). ![]()
