[An imaging study on location of the anterior border of facets and the posterior border of vertebral bodies in lower cervical spine].

Objective: To explore the location of the anterior border of facets and the posterior border of vertebral bodies in lower cervical spine,and to provide a quantitative data to evaluate the correct length of transarticual screws in lower cervical spine during procedure.

Methods: One hundred standard lateral X-ray films and fifty CT films on cervical spine were used to measure the distance of the anterior border of facets and the posterior border of vertebral bodies in lower cervical spine. HS, HM and HI were defined as parameters, which means the distance between the anterior border of the superior (HS), median (HM) and inferior (HI) part of facets and the posterior border of corresponding vertebral bodies.

[Anterior decompression and reconstruction for the treatment of burst thoracolumbar fractures with anterior and median column injury].

Objective: To explore the treatment of anterior decompression and reconstruction for burst thoracolumbar fractures with anterior and median column injury and to evaluate the therapeutic effect.

Methods: Thirty-four patients suffering from burst thoracolumbar fractures with anterior and median column injury (male 22 and female 12, aged from 20 to 63,with an average of 40.5 years) were treated by anterior decompression and reconstruction from May 2001 to October 2006.
