Key result
Placing both fixating screws within 3 mm of the femoral neck cortex in displaced fractures yielded a higher healing rate than placing only one screw in close contact (88.9% vs 59.1%; p<0.05).
Why the study?
Does cortical screw support improve the rate of union in femoral neck fractures?
Observational (n=72)

Cortical screw support may improve union rates in displaced femoral neck fractures; leaves open the need for randomized confirmation.
Lindequist et al. (1995) conducted an observational in Femoral neck fractures (n=72). Both fixating screws placed within 3 mm from the femoral neck cortex vs. Only one screw placed within 3 mm from the femoral neck cortex was evaluated on Fracture healing/union (p=<0.05). Placing both fixating screws within 3 mm of the femoral neck cortex in displaced fractures yielded a higher healing rate than placing only one screw in close contact (88.9% vs 59.1%; p<0.05).
