文献抄读--Cannulated Screw and Cable are Superior to Modified Tension Band in the Treatment of Transverse Patella Fractures 101 patients with a mean age of 56, were selected for the study. All of the patients were suffered patellar fractures with AO classification of 34-C1 and C2. Among those patients, 49 were performed cable-cannulated screw fixation, and 52 were performed modified k- wire fixation. Titanium cable-cannulated screw tension band fixation The figure are showing the method of cable-cannulated screw fixtion. Firstly ,two k-wires were introduced pass through the patellar fractures. Then ,the cannulated screw were screwed along with the k- wire. And two cables were threaded through the screws and tightened the fracture. Fracture fragment gaps, knee functional rehabilitations, fracture healing times, plications were evaluated pared between two types of fixations. Conclusion : ? The cable-cannulated screw tension band technique showed superior results and could be considered as an alternative method for treatment of transverse patellar fractures. puter Assistance Improve the Clinical and Functional Scores in Total Knee Arthroplasty? ? 73 patients were selected for analysis with a follow-up at lest 8 years. 36 patients were operated with the aid puted navigation, and 37 patients were performed standard arthroplasty surgery. ? wireless image-free navigation system (Stryker Image Free Computer Navigation System, versions and ; Stryker- Leibinger , Freiburg, Germany) .?
