    AIM: In this study, 31 patients with a diagnosis of Type II odontoid fractures were reported. All patients were treated with anterior transodontoid screw fixation and clinical outcomes were reported. MATERIAL and METHODS: In this study, the retrospective clinical analysis of 31 patients with traumatic type II odontoid fractures who were treated through anterior transodontoid fixation in Neurosurgery Department at VKV American Hospital between 1998 and 2012 was performed. The age, sex, cause of injury, diagnosis time, neurological examination before and after surgery, follow-up period were evaluated. The neurological status of patients was classified according to the Frankel scale. RESULTS: In 4 patients, 2 transodontoid screws were inserted. The mean hospital stay was 3.35 days. Posterior occipito-cervical fusion was done in 1 patient due to the lack of fusion in the first operation. No vascular injury, screw malposition, infection, neurologic deterioration, or complications were observed during the peroperative and postoperative stage. The mean postoperative follow-up period was 36 months after surgery. Radiological imaging of patients were performed at the early and late postoperative stage. CONCLUSION: We found satisfying fusion rates and better patient comfort during the postoperative period. We think that stabilization and fusion through a transodontoid screw is a minimal invasive method.

    Context: This study was designed to understand and define the special radio-anatomic morphometry of C7 vertebra by using multidetector computed tomography (MDCT). Aims: The major aim of the study was to detect the gender- and side-related morphometric differences of C7 vertebra among subjects. Setting and design: Our radiology unit database scanned for MDCT sections of the C7 vertebra. Materials and Methods: A total of 214 patients (134 men, 80 women) were selected. A detailed morphometric evaluation of C7 was done. Statistical analysis used: T test, ANOVA. Lamina length (P < 0.001), pedicle length (P < 0.001), outer cortical (P = 0.01) and inner cancellous pedicle (P < 0.001) width, pedicle angle to sagittal plane (P < 0.001) values were statistically significantly different on the right versus left side. When the results were stratified by gender, lamina length, inner cancellous lamina height, pedicle length, inner cancellous pedicle height, outer cortical pedicle width, lateral mass anteroposterior length, anteroposterior length of C7 corpus, height of C7 corpus (P < 0.001), C6-7 (P = 0.013) and C7-T1disc height (P = 0.04), transverse foramina perpendicular width at C7 (P = 0.046) values were found to be statistically significantly different. Vertebral artery most commonly enters into the transverse foramina at C6 level. Conclusions: Gender and side differences are important factors for preoperative planning and showed significant differences among subjects. MDCT is a practical option for investigating the exact anatomical features of osseous structures.
