[Fixation of trochanteric or subtrochanteric fractures using dynamic external fixators].

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Context:

• Trochanteric and subtrochanteric fractures often occur in elderly patients with significant operative risks (ASA III or IV).
• Existing fixation methods may pose challenges for high-risk patient populations.

Purpose:

• To present a novel dynamic external fixation system for managing trochanteric or subtrochanteric fractures.
• To evaluate the suitability of the Citieffe/CH-N fixator for elderly patients with high operative risk.

Summary:

• The Citieffe/CH-N fixator utilizes a 9 mm dynamic screw inserted into the femur neck and head.
• The system allows for controlled impaction, dynamic fixation via screw gliding, and distraction for deformity correction.
• This technique provides a simple, rapid solution with a low operative risk profile.

Impact:

• The dynamic external fixation system offers a minimally invasive approach for complex fractures in vulnerable patients.
• Potential for reduced operative time and complications compared to traditional methods.
• Facilitates fracture healing and deformity correction with adjustable dynamic capabilities.
