• ABSTRACT
    • Background Femoral neck fractures are common injuries. Although many studies have compared two-hole dynamic hip screw (DHS) versus multiple cannulated cancellous screw (CCS) fixation for undisplaced intracapsular fractured neck of femurs (NOF), there is no consensus on which surgical technique results in better outcomes. The aim of our study was to compare DHS and CCS for undisplaced NOFs. The primary outcomes were reoperation and mortality rates at one year postoperatively. Methodology A retrospective analysis was performed involving all patients who underwent fixation with DHS/CCS for an undisplaced intracapsular NOF at our hospital between January 2016 and December 2020. All patients had a minimum follow-up time greater than one year. All patients underwent a standardised NOF protocol. Patients either underwent DHS or CCS fixation according to surgeon preference, and there was no randomisation to either group. Results A total of 41 patients underwent fixation with DHS compared to 32 who underwent CCS. The reoperation rate at one year was 9.8% in the DHS group compared to 6.3% in the CCS group. This difference was not statistically significant (p = 0.588). The one-year mortality rate was similar between groups at 22.0% and 21.9% in the DHS group and the CCS group, respectively (p = 0.994). Registrar-level surgeons performed 80.5% of DHS compared to 59.4% of CCS, and consultant surgeons performed 4.9% of DHS compared to 25% of CCS. Conclusions There was no significant difference in revision rates or complications seen between CCS and DHS. A significantly higher percentage of CCS fixations were performed by consultant-grade surgeons at our hospital compared to DHS. This study provides further data on the choice of fixation method for intracapsular fractures. It also reports on the grade of the operating surgeon at our unit, which may be a factor in the quality of fixation and ultimately reoperation rates.
