PLIF with a titanium cage and excised facet joint bone for degenerative spondylolisthesis--in augmentation with a pedicle screw.
To determine the validity of posterior lumbar interbody fusion (PLIF) using a titanium cage filled with excised facet joint bone and a pedicle screw for degenerative spondylolisthesis. ⋯ PLIF using a titanium cage filled with excised facet joint bone and a pedicle screw provided a satisfactory clinical outcome and an excellent union rate without harvesting and grafting the autologous iliac bone.

The authors report 4 cases of Charcot spine treated surgically. In the surgical treatment, combined anterior and posterior with extensive debridement, autogenous bone grafting, and posterior instrumentation is the main therapeutic modality. Some cases with mild bone destruction could be treated by posterior interbody fusion. For the unstable, symptomatic Charcot spine, surgical treatment can provide excellent results.

Thoracic pedicle screw insertion in scoliosis using posteroanterior C-arm rotation method.
Previous researches have emphasized the importance and difficulties in accurate thoracic pedicle screw insertion in scoliosis patients. However, there has been no report on accuracy of the insertion using posteroanterior C-arm fluoroscopy rotated to allow en face visualization of the pedicle in humans. This study aimed to evaluate the accuracy of the thoracic pedicle screw insertion technique using a C-arm fluoroscopy rotation method for the treatment of scoliosis. ⋯ Thoracic pedicle screw insertion in scoliosis patients using the posteroanterior C-arm rotation method allows en face visualization of both pedicles by rotating the C-arm to compensate for the rotational deformity, making it a practical, simple and safe method.
