PURPOSE: To evaluate fixation failure following femoral neck system fixation (FNS) for intracapsular femoral neck fractures (FNF) and to determine whether fracture characteristics, particularly fracture orientation, were associated with fixation failure. METHODS: A retrospective cohort study was performed at a Level I trauma center. 82 patients with intracapsular femoral neck fractures treated with FNS fixation were included. Fixation failure was defined as implant cut-out, loss of fixation, nonunion, or revision surgery. Associations between fracture characteristics and fixation failure were evaluated. RESULTS: The mean age was 70.1 ± 12.7 years, with a mean follow-up of 22.2 ± 10.2 months. Eight fixation failures occurred (9.8%). Pauwels classification was significantly associated with fixation failure (p
