# Clinical application of the femoral neck system in the treatment of femoral neck fractures

## TL;DR

This study compares two surgical methods for treating femoral neck fractures and finds that the femoral neck system leads to faster healing and fewer complications.

## Contribution

The study provides evidence that the femoral neck system is more effective than cannulated compression screws for treating specific femoral neck fractures in young to middle-aged patients.

## Key findings

- The FNS group had significantly shorter healing time and higher hip scores compared to the CCS group.
- Femoral neck shortening and hardware failure were less frequent in the FNS group.
- FNS is associated with fewer fixation-related complications and better early hip function recovery.

## Abstract

The research was conducted to assess the therapeutic efficacy of the femoral neck system (FNS) and cannulated compression screw (CCS) in treating femoral neck fractures classified as Pauwels type II and III in young to middle-aged patients.

This retrospective cohort study included 46 patients treated at Yanbian University Affiliated Hospital between January 2021 and March 2023. Patients were allocated into two groups: FNS (n = 24) and CCS (n = 22). Clinical indicators, including bone healing duration, Visual Analog Scale (VAS), Harris Hip Score (HHS), and postoperative complications, were compared.

Satisfactory fracture reduction was consistently accomplished in all individuals, with observation continuing over 9 to 24 months. Baseline characteristics were comparable across both groups. The FNS group showed a significantly shorter healing time (4.00 ± 1.00 vs. 4.79 ± 1.39 months, P < 0.05), and higher HHS at 3 and 6 months following surgery (P < 0.05). VAS scores and 1-month HHS showed no significant differences between groups. Femoral neck shortening (4.2% vs. 27.3%, P = 0.043) and hardware failure (4.2% vs. 31.8%, P = 0.020) were significantly less frequent in the FNS group, while rates of femoral head necrosis (4.2% vs. 9.1%) and nonunion (12.5% vs. 13.6%) were comparable.

FNS promotes faster fracture recovery, reduces fixation-related complications, and improves early hip function, making it a reliable and efficient option for surgical stabilization of femoral neck fractures in young and middle-aged populations.
