OBJECTIVES: This study assesses the efficacy of dynamic hip screw (DHS) versus cannulated screws for femoral neck fractures, focusing on femoral neck shortening, avascular necrosis (AVN) incidence, and functional outcomes. METHODS: Design: Retrospective cohort study. Setting: Academic Level I Trauma Center. Patient Selection Criteria: Included were patients with femoral neck fractures treated with DHS or cannulated screws, with follow-up data available. Outcome Measures and Comparisons: Main outcomes were femoral neck shortening, incidence of AVN, and Harris Hip Score (HHS) for functional assessment.
