Abstract

Purpose
This study compared the clinical and radiological results of the femoral neck system (FNS) and cannulated compression screws (CCS) for the fixation of femoral neck fractures.
Materials and Methods
Patients who underwent FNS or CCS internal fixation for femoral neck fractures between January 2016 and January 2022 were analyzed retrospectively. The hip joint function using the Harris hip score (HHS) was evaluated three months and one year after surgery. The operation time, fracture healing time, and associated surgical complications in the two groups were compared and analyzed statistically.
Results
Seventy-nine patients were categorized into 38 FNS and 41 CCS groups. The FNS group had a longer operation time and higher postoperative HHS at three months (p<0.01). Femoral neck shortening was lower in the FNS group (p=0.022). There were no significant differences in the fracture healing time and other complications.
Conclusion
There were no differences in most clinical outcomes and complications between the two groups except for the three-month HHS and femoral neck shortening. This study suggests that FNS could be an alternative to CCS for treating femoral neck fractures.
