Key result
An apex-distal screw configuration for femoral neck fixation tolerated a greater mean load to failure (11,330 N) compared with an apex-proximal configuration (7,795 N) in human cadaveric femora.
Why the study?
Does an apex-distal screw configuration tolerate higher loads to subtrochanteric fracture compared to an apex-proximal configuration in human cadaveric femora?
Does an apex-distal screw configuration tolerate higher loads to subtrochanteric fracture compared to an apex-proximal configuration in human cadaveric femora?
Absolute Event Rate: 11330% vs 7795%
An apex-distal configuration for cannulated screw fixation of femoral neck fractures tolerates higher loads to failure than an apex-proximal configuration in a cadaveric model.
No takes yet. Share an insight, caveat, or question.
May favor apex-distal screws for greater cadaveric load tolerance; hypothesis-generating and should not yet change practice.
Oakey et al. (2006) studied Femoral neck fracture. Apex-distal screw configuration vs. Apex-proximal screw configuration was evaluated on Ultimate load to failure (force to fracture). An apex-distal screw configuration for femoral neck fixation tolerated a greater mean load to failure (11,330 N) compared with an apex-proximal configuration (7,795 N) in human cadaveric femora.
