Functional and Radiological Outcomes of Calcar Buttress Biplane Double-Supported Screw Fixation (BDSF) Using a...

Area of Science:

• Orthopedic Surgery
• Traumatology
• Biomedical Engineering

Background:

• Intracapsular femoral neck fractures in adults aged 40-60 pose treatment challenges.
• Calcar buttress fixation enhances load transfer via dual cortical support.

Purpose of the Study:

• Evaluate functional and radiological outcomes of calcar buttress BDSF using a locking compression screw system.
• Assess outcomes in adults aged 40-60 with intracapsular femoral neck fractures.

Main Methods:

• Prospective observational study of 25 patients (aged 40-60) with intracapsular femoral neck fractures.
• Closed reduction and internal fixation with calcar buttress BDSF and a titanium locking compression screw system.
• Assessed using Harris Hip Score (HHS) and Visual Analogue Scale (VAS) at 1, 3, 6, and 12 months.

Main Results:

• Significant improvement in mean HHS from 72.72 at 1 month to 87.84 at 12 months (p < 0.001).
• Mean VAS decreased significantly from 8.04 to 2.68 (p < 0.001).
• 96% overall radiological union at 12 months; excellent/good outcomes in 84% of patients.

Conclusions:

• Calcar-buttress BDSF fixation is a promising head-preserving technique for intracapsular femoral neck fractures in this age group.
• Encouraging early functional and radiological results observed.
• Larger comparative studies are needed due to modest sample size and wide confidence intervals.
