Abstract Introduction Osteosynthesis of femoral neck fractures (FNFs) is an important treatment option, especially for younger patients. We aimed to assess the rate early implant-related complications in FNF osteosynthesis using Femoral Neck System (FNS). Patients and methods Consecutive patients diagnosed with displaced or nondisplaced FNFs were treated FNS this prospective, observational, multicenter investigation. followed up minimally 3 months 12 if radiologic bone union no pain was not achieved beforehand. Predefined treatment-related adverse events (AEs, defined as implant failure, loss reduction, iatrogenic fractures, deep infection, surgical revision), union, patient-reported Harris hip score (HHS) EQ-5D-5L index assessed. Results One hundred twenty-five included study. Thirty-eight (30.4%) (Garden III IV), 37 (29.6%) vertical (Pauwels type III). AE at 8 patients, 6.4% (95% CI, 2.8–12.2), months, 11 8.8% 4.5–15.2). Cumulative incidences 68% 90% 6 98% months. The mean changes HHS between preinjury -7.5 [ – 21.1] [6.2]) 0.03 0.21] [0.15]), respectively; neither statistically significant. Conclusion current study on resulted complication rates 2.8–12.2) 4.5–15.2) On average, returned function quality life. may also indicate that conventional wisdom treating stable aged 60 80 years need be reconsidered.
