Reoperation for sliding hip screws vs cannulated cancellous screws in femoral neck fractures: A study from the Danish Fracture Database Collaborators.

Introduction: It is still debated whether to use cannulated cancellous screw (CCS) or sliding hip screw (SHS) implants for femoral neck fracture (FNF) patients but there are no studies large enough to evaluate on smaller differences. The aim were to compare the reoperation and mortality rates of a large cohort of FNF patients above 60 years of age with internal fixation using CCS and SHS implants, with stratification by fracture classification.

Methods: This register study employed prospectively collected data from 2014 to 2018 from the Danish Fracture Database, including 2-year follow-up and data on age, sex, surgery, comorbidity and fracture classification.
