An experimental study using cadaveric vertebrae. ⋯ The new cannula may improve vertebroplasty by significantly easing cement injection. It is cost effective and can be easily integrated into the existing procedure.
-
Prospective case series with historical controls (normative data). ⋯ CLBP patients, especially men, seem to have a reduced aerobic fitness level compared with the normative population. No explanatory factor for that loss could be identified.
-
A reliability study was conducted. ⋯ The ossification-kyphosis angle in the sagittal view of MRI has potential as an indicator of the effectiveness of posterior decompression in this disease. It is thought that there is a critical point of posterior decompression at nearly 23 degrees of the ossification-kyphosis angle of the decompression site. When the ossification-kyphosis angle is more than 20 degrees , the presence of echo free space should be carefully confirmed in intraoperative ultrasonography.

Test-retest design to examine interrater reliability. ⋯ Reliability of the classification algorithm was good. Further research is needed to identify sources of disagreements and improve reproducibility.
