DHS AND ANTI-ROTATIONAL SCREW VS CANNULATED SCREWS IN FEMORAL NECK FRACTURES. THERE ARE DIFFERENCE IN CLINICAL OUTCOME AND INCIDENCE OF AVN?

The purpose of this study was to compare the period of union, functional outcomes and complications of patients with femoral neck fractures treated with percutaneous cannulated screws versus dynamic hip screw (DHS) and antirotational screwWe enrolled 160 consecutive patients with a fracture of the neck of the femur,according to Garden classification treated from 2010 to 2011. The average age was 67.8 years. The patients were referred for treatment with cannulated screws or to treatment with DHS plate and anti-rotational screw. All patients were followed up with a minimum follow-up of 1 year. The Harris Hip Score was used.In the two study groups the differences in consolidation and functional results were not statistically significant. The increased risk of avascular necrosis is realted with the degree of displacement rather than the surgical treatment. The blood loss was significantly lower in group I, due to the smaller incision (screws were applied percuataneously).The preliminary results of our study were a not superiority of one surgical technique over the other, by assessing the time to bone healing and the functional results.
