Introduction

Intracapsular fracture neck of femur has been a challenge to orthopedic surgeons and internal fixation with conventional technique is often associated with poor outcomes. The BDSF technique introduced by Filipov has shown encouraging clinical outcomes and reduced fixation failure rates in published series. However, comparative data between BDSF and conventional cancellous screw fixation (CFIX) remain limited. This study aimed to compare the clinical and radiological outcomes of both fixation modalities.

Methodology

A prospective comparative study was conducted for 2 years including 60 patients, treated with either BDSF (Group A, n = 30) was compared with CFIX method (Group B, n = 30) in displaced fracture neck of femur. Functional outcomes were assessed using Modified Harris Hip scoring system (HHS) and radiological outcome was assessed by serial hip X-ray.

Results

93.33% cases united post-operatively in group A and 90% cases in Group B but it was not statistically significant. All the failure cases had Garden IV fractures & posterior comminution. Average union time in BDSF method was 12.55 weeks compared to 14.68 weeks in CFIX (p < 0.05). Significantly superior functional outcomes at 1 month and 3 months in BDSF group (mean HHS 85.28 and 87.80) compared to CFIX group (mean HHS 72.20 and 82.07) (p < 0.05).

Conclusion

The BDSF technique demonstrated earlier union and better early functional outcomes compared with CFIX, with comparable overall union and complication rates. These findings suggest that BDSF may be a promising alternative fixation option for displaced intracapsular neck of femur fractures.
