Multicenter Study Comparative StudyA comparative study between local bone graft with a cage and with no cage in single posterior lumbar interbody fusion (PLIF): a multicenter study.
A retrospective study was performed to compare the clinical and radiological results between local bone graft with a cage and without using a cage in patients treated with posterior lumbar interbody fusion surgery. ⋯ Local bone graft without a cage is as beneficial as that with a cage for PLIF. Comparing with local bone graft using a single cage, we believe that the purely local bone graft is a more ideal way in single PLIF.

Multicenter Study Comparative StudyGrip force monitoring on the hand: Manugraphy system versus Jamar dynamometer.
For clinical grip force assessment, the Jamar dynamometer is a wide accepted tool. Users have to be aware that this method does not represent all grip efforts applied. The Manugraphy system is a tool that measure total grip force as well as identify load distribution patterns of the hand while gripping cylinders wrapped with calibrated capacitive matrix sensor mats. The aim of this study was to validate an assessment setting of the Manugraphy system for clinical use. Further, the relationship and difference between the Manugraphy system and the Jamar dynamometer were investigated. ⋯ The force values, obtained using the two systems, have a high correlation but are not directly comparable. Both systems allow valid and constant grip force measurement. As the sensor mat detects all forces applied perpendicularly to the cylinder surface, it characterizes grip force better than the Jamar dynamometer. In addition, information about load distribution of the hand is gained.
