The mean age was 42 years, 36% were female, and the average Pauwels' angle of fractures was 55 degrees. There were 305 patients treated with multiple cannulated screws (MCS) and 260 treated with a fixed-angle (FA) construct. Treatment failures were 46% overall, but was more likely to occur in MCS constructs versus FA devices (55% vs. 36%, <jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.001). When FA constructs were substratified, the use of a sliding hip screw with addition of a medial femoral neck buttress plate (FNBP) <jats:italic toggle=\"yes\">and<\/jats:italic> \u201cantirotation\u201d (AR) screw demonstrated better results than either FNBP or AR screw alone or neither with the lowest overall construct failure rate of 11% (<jats:italic toggle=\"yes\">P<\/jats:italic> &lt; 0.036).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>Historically used fixation constructs for femoral neck fractures (eg, multiple cannulated screws and sliding hip screw) in young and middle-aged adults performed poorly compared with more recently proposed constructs, including those using a medial femoral neck buttress plate and an antirotation screw. Fixed-angle constructs outperformed multiple cannulated screws overall, and augmentation of fixed-angle constructs with a medial femoral neck buttress plate and antirotation screw improved the likelihood of successful treatment. Surgeons should prioritize fixation decisions when repairing displaced femoral neck fractures in patients.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>LEVEL OF EVIDENCE:<\/jats:title>\n            <jats:p> Therapeutic Level III.
