BACKGROUND:Denis B thoracolumbar burst fractures are common spinal injury and may be involved in the upper end plate injury. Fracture reduction and pedicle screw fixation are used to repair above injury. This scheme can effectively achieve the aim of correcting deformity, but the trabecular bone after crushing cannot be fuly recovered. OBJECTIVE:To observe the repair effect of fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body on Denis B thoracolumbar burst fracture, and compare with fracture reduction and pedicle screw fixation alone. METHODS:Clinical data of 70 cases of Denis B thoracolumbar burst fractures, who were treated in the Department of Orthopedics, Zhangjiagang Aoyang Hospital from January 2012 to December 2014, were retrospectively analyzed. According to repair scheme, they were equaly divided into two groups. Patients in the control group received fracture reduction and pedicle screw fixation. Patients in the observation group received fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body. Oswsetry Disability Index, height of anterior border of injured vertebral body, lower back pain visual analogue scale and vertebral kyphosis Cobb’s angle were compared and observed between the two groups before repair, 1 week, 3 and 6 months after repair. RESULTS AND CONCLUSION:No significant difference in Visual Analogue Scale was detected at 1 week, 3 and 6 months after repair between the observation and control groups (P > 0.05). Oswsetry Disability Index was significantly lower in the observation group than in the control group (P < 0.05). No significant difference in the height of anterior border of injured vertebral body was detected between the observation and control groups (P > 0.05). Cobb’s angle was significantly lower in the observation group than in the control group (P < 0.05). These findings suggest that fracture reduction and pedicle screw fixation + artificial bone graft in vertebral body obtained good repair effects on Denis B thoracolumbar burst fracture, not only effectively corrected Cobb’s angle and the height of anterior border of injured vertebral body, but also helped to restore normal spinal loads by filing bone in the injured vertebral body.

Objective In order to improve the teaching effectiveness of anatomy in nursing, this article made an exploration on the experimental teaching reform combined with the characteristics of nursing profession. Methods The nursing students of class 1and 2 of 2013were set as the research object. The class 1 (110) as experimental class, class 2 (110) for the control group. In the experimental class, the reform of teaching method and teaching quality was improved by adjusting the teaching syl-labus and teaching contents. The control class used the traditional experimental teaching method. The experiment class' teaching reform research of the human anatomy carried on the 1 semester. Exam achievement evaluation and the questionnaire survey were adopted to assess the teaching effect. SPSS 13.0 software was used to do statistical analysis and t test was used to compare two groups of students test scores, experiment grades, test scores and total scores. Results Experimental theory examination results [(47.80±7.30) vs. (44.85±8.38)], experiment grades [(15.48±1.76) vs. (14.55±2.19)], ex-periment test scores [(15.52±2.22) vs. (14.35±2.64)], total score [(78.80±8.99) vs. (73.75±10.53)] were better than control group (P<0.05). In questionnaire survey,more than 80% of the students think that the reformed teaching method can help to improve the teaching effect. Conclusion In human anatomy experiment teaching reform, the reformed experiment teaching method can significantly improve students' scores and the teaching effect. It is better than the traditional method, and is worth publicizing.
