Treating Displaced Patellar Fracture with Longitudinal Incision & Internal Fixation of the Sidelong Anterior Tension-band Wiring

Objective To explore the clinic effects of treating the displaced patellar fracture with a small longitudinal midline incision and internal fixation of the sidelong figure-of-eight anterior tension-band wiring.Methods 93 cases of the displaced patellar fractures were internal fixated with the sidelong figure-of-eight anterior tension-band wiring(1.2 mm) simply,which made a longitudinal midline incision,it length can be made equal to the diam of patella approximately,that gives to enough expose the entire anterior surface of the patella and the patellar tendons.Results Follow-up for 6 to 30 months,93 cases were all obtained bony union.By Zhang Chun-cai score,there were 67 cases excellent,23 good and 3 fair,the excellent and good rate was 96.8%.Conclusion Treating patellar fracture with the fixation methods are very stabilization,and can functional exercise in early.It had similar results to reports using modified(with Kirschner wires) tension band techniques.The methods is simple and mini-trauma and invasive device minimally which results in fewer complications,especially as fractures traversed and comminuted with relative larger fragments are concerned.
