A finite element model of cervical spine was three-dimensionally reconstructed through computed tomography (CT) scan, recording the edges of image using Snigraphics V18.0 software, and calibrating in sequence of point, line, area, and solid. The stress distribution of cervical C_(3-4) was analyzed using compute aided design to validate the availability of reconstructed models. Results showed that the three-dimensional finite element cervical C_(3-4) was feasible in simulation analysis. These indicate that the established three-dimensional finite element models can simulate biomechanical experiments, providing foundations for analyzing biomechanical performance of local structure of this finite element model under various pressure conditions.

Objective To analyze the clinical manifestations,treatment and prognosis of adult medulloblastoma (MB).Methods A total of 163 cases of adult MB,confirmed by surgical and pathological diagnosis,were retrospectively analyzed about the clinical manifestations,imaging,treatment and prognosis.There are 108 males and 55 females in the group,whose average age was 28.6-year-old.Results The main clinical manifestations include headache,nausea,vomiting,dizziness,gait disturbance,hypopsia,diplopia,hearing loss and cerebellum crisis.Gross total resection was achieved in 90 cases,subtotal resection in 67 cases and biopsy in 6 cases.Survival time from surgery to progression or death or the last date of follow-up were measured and estimated by the Kaplan-Meier method.Among a total of 160 follow-up patients with MB,postoperative overall survival time was from 7 to 170 months,median survival time was (127±6) months (95％ CI 115.3-138.68).The 5-year overall survival time of adult MB patients was 73.1％ (120/163).The log-rank test was used to compare the significance of the following prognostic variables.Among all clinical factors,patients undergoing the craniospinal irradiation had a significantly better survival rate than those without this treatment (44 months vs 34 months,x2 =8.712,P =0.003).Conclusion Good therapeutic effect of MB be achieved by adopting surgical resection with early enough craniospinal irradiation.Recurrence and metastasis are the two main factors for bad prognosis in adult MB.
