Clinical Report: Evaluating Treatment Options for Vancouver B2 PFFs

Overview

This study compares the outcomes of open reduction and internal fixation (ORIF) versus stem revision (SR) for Vancouver type B2 periprosthetic femoral fractures (PFFs). Findings indicate that while SR is traditionally considered the gold standard, ORIF may be a viable alternative in selected cases.

Background

Periprosthetic femoral fractures (PFFs) are serious complications following total hip arthroplasty (THA), with an incidence of 3.5% after primary THA and up to 12% after revision. Vancouver type B2 fractures, characterized by a loose stem and good bone stock, pose unique treatment challenges. The optimal management strategy remains unclear, necessitating a comparison of surgical options.

Data Highlights

Key Findings

• 56 patients with Vancouver type B2 PFFs were initially reviewed, with 48 included in the analysis.
• Patients were divided into two groups: 25 underwent stem revision (SR) and 23 underwent open reduction and internal fixation (ORIF).
• The preoperative assessment for ORIF included specific criteria related to fracture location and stem type.
• Radiographic outcomes were evaluated based on the Beals and Tower criteria for stability and healing.
• Complications and functional outcomes were compared between the two surgical approaches.

Clinical Implications

Surgeons should consider both ORIF and SR for Vancouver B2 PFFs, weighing the patient's specific circumstances and fracture characteristics. The decision-making process should involve careful intraoperative assessment of stem stability.

Conclusion

The study highlights the need for further investigation into the optimal treatment for Vancouver B2 PFFs, suggesting that ORIF may be a suitable alternative to SR in selected cases.
