A comparison was made between patients with femoral neck shortening (&gt;5 mm) and those without (&lt;5 mm).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>A total of 45 patients were included in this study. The mean age of the patients was 70.2 (50\u201389) years, and 68.9% were women. No early postoperative complications, such as postoperative infection, deep vein thrombosis, or pulmonary embolism, were observed. All patients achieved bone union within 23 weeks. The average femoral neck shortening was 2.6 mm (0\u201316.8), with femoral neck shortening &gt;5 mm observed in 7 patients (15.6%). Significant femoral neck shortening was observed in patients with displaced fractures compared with those with nondisplaced fractures (<jats:italic toggle=\"yes\">p<\/jats:italic> = 0.006). One patient developed avascular necrosis of the femoral head. No metal fixation failure was observed.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>In patients aged 50 years or older, TFNA fixation for nondisplaced femoral neck fractures demonstrated relatively minimal femoral neck shortening and a low complication rate, indicating that it is an effective technique for treating these fractures. However, for displaced fractures, surgeons should be mindful of the potential for excessive neck shortening and carefully select the surgical method.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>LEVEL OF EVIDENCE:<\/jats:title>\n            <jats:p>Therapeutic Level IV.
