Mandibular fracture reduction with eccentric dynamic compression plate: new treatment for an old problem

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• Orthopedic Surgery

Background:

• Mandibular fractures present challenges in fixation, particularly in edentulous patients.
• Existing fixation methods may have limitations in achieving optimal bone healing.
• The Speissl Eccentric Dynamic Compression Plate (EDCP) and Dynamic Compression Plate (DCP) offer a novel approach.

Purpose of the Study:

• To describe the technique and theory of EDCP and DCP application for mandibular fracture fixation.
• To report initial clinical experience with these plates in edentulous or nearly edentulous patients.
• To evaluate the efficacy and outcomes of EDCP/DCP in mandibular fracture repair.

Main Methods:

• Application of 15 EDCP/DCP plates in ten patients with edentulous or nearly edentulous mandibles.
• Surgical fixation of mandibular fractures using the described compression plate techniques.
• Clinical follow-up to assess bony healing and complications over 18 months.

Main Results:

• Satisfactory bony healing was achieved in 14 out of 15 mandibular fracture sites.
• Four out of 15 fracture sites experienced soft tissue infections.
• The overall bony union rate was high, indicating successful fracture consolidation.

Conclusions:

• The EDCP and DCP techniques demonstrate significant potential for effective mandibular fracture fixation.
• While soft tissue infections are a concern, satisfactory bony healing rates suggest clinical viability.
• This technique may revolutionize mandibular fracture therapy, especially in challenging patient populations.
