新型脊柱固定器治疗多节段脊柱骨折12例

多节段脊柱骨折(multiple segmental spinal injuries ,MSSI)的治疗在临床上是一个较难解决的问题,笔者利用新型脊柱固定器(new spinal fixation instrument,NSFI) [1]可灵活组装并延长的特点,治疗胸腰椎及腰椎MSSI,取得良好效果.报告如下.

内源性神经干细胞与脊髓损伤

1992年Reynodl与Wesis首次报告体外成功培养神经干细胞(neural stem cell,NSC),NSC的应用研究逐渐成为生命科学研究的热点.

Objective: To provide the experience in imaging diagnosis of cervical spine and spinal cord injuries in children.Methods: Imaging data of cervical spine and spinal cord injuries in 62 children were retrospectively reviewed.The routine radiography including the lateral,anteroposterior and open-mouth odontoid views were performed in all the patients. Tomography was available for 25 patients, and flexion-extension lateral views for 28patients, CT scanning for 21 patients, MRI for 26 patients.Results: Of these patients, 46 patients were identified with injuries of upper cervical spine (9 with atlantal arch fracture, seven with axial fracture, 21 with odontoid fracture, 1 with atlantal arch fracture combining with odontoid fracture, and 1 with atlantal transverse ligament disruption); 7 patients sustained injuries of lower cervical spine (3 fractures of vertebral body, 2 dislocations and 6fracture-dislocations ); 2 patients had multiple noncontiguous cervical injuries; and 3 had cervical spinal cord injury without radiographic abnormalities (SCIWORA).Conclusions: Imaging assessment is of great importance in the diagnosis of cervical spine and spinal cord injuries in children. Whenever cervical spine and spinal cord injuries are suspected for children patients, and the three-views should be routinely indicated. MRI should be routinely performed in all children with cervical SCIWORA.
